OPINION
ANNE GARDNER, Justice.
Appellant Betty W. appeals a final order terminating her parental rights to her three children, D.W., T.W., and S.G. In [629]*629four issues, she complains that (1) the one-year dismissal deadline imposed by section 268.401(a) of the Texas Family Code violates the Separation of Powers Clause of the Texas constitution; (2) the trial court erred by denying her motion to extend the one-year dismissal deadline; (3) section 263.405(i) of the family code, barring review by appellate courts of issues not listed in a statement of points in the trial court, violates the Separation of Powers Clause of the Texas constitution; and (4) section 263.405® also violates due process under the United States Constitution. We hold that Betty failed to preserve her first issue under the rules of appellate procedure; that section 263.405® violates the Separation of Powers Clause of the Texas constitution; but that, on the merits- of Betty’s second issue, the trial court did not abuse its discretion by overruling Betty’s motion to extend the one-year dismissal deadline. Accordingly, we affirm.
I. Procedural Background
Betty is the biological mother of D.W., T.W., and S.G.1 The Texas Department of Family and Protective Services (“Department”) filed a petition seeking to terminate the parent-child relationship between Betty and her two older children, D.W. and T.W., on June 6, 2005. Betty gave birth to S.G. on July 12, 2005. The Department subsequently filed an amended petition adding S.G.
The trial court set a final hearing in this case for April 3, 2006. Betty filed a “Motion For Extension Of Time To Dismiss Suit Or Render Final Order And Alternative Motion For Continuance” on March 22, 2006. She sought to extend the final hearing deadline by 180 days or, alternatively, to continue the trial date until a time closer to the original dismissal deadline.2 The trial court’s docket sheet reflects that the trial court granted Betty a continuance but only reset the final hearing to May 16, 2006, still within the existing one-year dismissal deadline. Prior to the beginning of the termination hearing on May 16, 2006, Betty’s trial counsel re-urged her motion requesting a 180-day extension, but the trial court denied it.
After a hearing on the merits, the trial court found that Betty knowingly placed or knowingly allowed the children to remain in conditions or surroundings which endangered their physical or emotional well-being, that Betty engaged in conduct or placed the children with persons who engaged in conduct which endangered their physical or emotional well-being, and that termination of the parent-child relationship was in the best interest of the children. The trial court rendered its final order terminating Betty’s parental rights to all three children on May 16, 2006.
On May 31, 2006 — the fifteenth day after the trial court entered its termination order — Betty’s trial counsel filed a notice of appeal and statement of points for appeal, raising only insufficient-evidence [630]*630points.3 On June 1 — the sixteenth day- — • the trial court granted trial counsel’s motion to substitute and appointed appellate counsel to represent Betty.
On June 6 — the twenty-first day after the trial court signed its final order — appellate counsel filed a “Motion for New Trial and Supplemental Statement of Points on Appeal.” In her supplemental points, Betty contended that the evidence was factually insufficient to support the trial court’s order and that family code section 263.405(i) violates the separation of powers provision of the Texas constitution and the Due Process Clause of the United States Constitution. This appeal followed.
II. Discussion
As previously noted, Texas Family Code section 263.401 provides a one-year dismissal deadline for a suit affecting the parent-child relationship filed by the Department that requests termination or con-servatorship, with a one-time extension of 180 days based upon proof of “extraordinary circumstances”:
(a) Unless the court has rendered a final order or granted an extension under Subsection (b), on the first Monday after the first anniversary of the date the court rendered a temporary order appointing the department as temporary managing conservator, the court shall dismiss the suit affecting the parent-child relationship filed by the department that requests termination of the parent-child relationship or requests that the department be named conservator of the child.
(b) The court may not retain the suit on the court’s docket after the time described by Subsection (a) unless the court finds that extraordinary circumstances necessitate the child remaining in the temporary managing conservator-ship of the department and that continuing the appointment of the department as temporary managing conservator is in the best interest of the child. If the court makes those findings, the court may retain the suit on the court’s docket for a period not to exceed 180 days after the time described by Subsection (a).4
The version of family code section 263.405® applicable to this suit provides:
The appellate court may not consider any issue that was not specifically presented to the trial court in a timely filed statement of the points on which the party intends to appeal or in a statement combined with a motion for new trial.5
Thus, section 263.401 deals with the dismissal deadline while section 263.405® deals with what issues we may consider on appeal.
A. Section 263.401’s Dismissal Deadline and Separation of Powers
In her first issue, Betty argues that the legislative dismissal deadline found in section 263.401 violates the separation of powers provision of the Texas constitution by interfering with the trial courts’ judicial [631]*631power to determine the timing and speed of disposition of causes. But Betty failed to raise this issue in the trial court.
To preserve her complaint for our review under the Texas Rules of Appellate procedure, Betty must have presented to the trial court a timely request, objection, or motion that states the specific grounds for the desired ruling, if the grounds are not apparent from the context of the request, objection, or motion, and she must have obtained an explicit or implicit ruling from the trial court.6 If a party fails to do this, error is not preserved, and the complaint is waived.7 Even a constitutional challenge to the facial validity of a statute may apparently be waived if not properly raised in the trial court.8
Betty argues the Separation of Powers Clause renders the dismissal statute void so that preservation of her first issue in the trial court was not required. But the cases she relies upon involved challenges to void judgments, which can be attacked at any time, not void statutes.9 Betty is not contending that the judgment is void; she is complaining that the judgment is erroneous because the statute in question imposes arbitrary deadlines that prevented her from properly presenting her defense.10 Thus, Betty’s complaint does not involve the type of challenge of facial unconstitutionality of a statute that may be asserted for the first time on appeal.
Betty also concedes in her brief that neither her original nor her supplemental statement of points contained a complaint regarding the constitutionality of section 263.401. Because Betty never raised the constitutionality of section 263.401 in the trial court, she cannot raise that issue on appeal.11 Therefore, we overrule her first issue.
B. Trial Court’s Denial of Betty’s Motion to Extend Dismissal Deadline
1. Preservation of Error
In her second issue, Betty argues that the trial court erred by denying her [632]*632motion for a 180-day extension of the dismissal deadline because she showed extraordinary circumstances. Unlike Betty’s first issue, this issue was preserved for appeal not just once but twice pursuant to appellate rule 33.1 — first by her pretrial motion for extension of the final hearing deadline by 180 days and second by her action in re-urging that motion before trial began — and she obtained a ruling by the trial court on both occasions.12
2. New Section 263.405(i) as a Bar to Considering Betty’s Second Issue
Nevertheless, the Department contends that section 263.405© bars us from considering Betty’s second issue because she failed to list it in her original statement of points filed within fifteen days after the judgment was signed as required by section 263.405(b). This brings us to Betty’s third issue, in which she contends that, to the extent section 263.405® bars our consideration of her issue on the merits, it violates the Separation of Powers Clause of the Texas constitution.13
As a threshold matter, we must determine whether we are precluded from considering Betty’s third issue challenging the constitutionality of section 263.405® because that issue was likewise not included in her original statement of points. As we have already noted, while Betty did not challenge section 263.405(i)’s constitutionality in her original statement of points, she did list that “point” in her supplemental statement of points and motion for new trial.14
Nevertheless, because her supplemental statement of points was not filed within the fifteen-day period required by section 263.405(b), the Department argues that section 263.405® bars us from even considering Betty’s complaints about that section’s constitutionality. But our ability to consider points not filed in the trial court within fifteen days did not even come into question until after the appeal reached this court.
Specifically, Betty’s complaint of the unconstitutionality of section 263.405® under the Separation of Powers Clause raises the question of whether that statute unduly interferes with this Court’s own power and authority to exercise its core judicial functions. This issue could not have been addressed by the trial court in the first instance and thus need not have been preserved in the trial court to be raised here.15
[633]*633We hold that Betty properly preserved her complaint that the statute violates the Separation of Powers Clause by raising the issue in her brief in this court.
a. History of Section 263.405(i)
Chapter 263 of the family code provides for hearings for temporary and permanent placement, conservatorship, and termination of parental rights in cases involving dependent and neglected children removed from their homes and placed in foster care by the Department. In 1997, the legislature enacted amendments to chapter 263 to reduce delays in the time spent in foster care by a child awaiting a final decision in a proceeding to terminate parental rights by imposing a one-year limitation for a final order with the possibility of a onetime 180-day extension.16
In 2001, the legislature passed additional amendments to the family code to expedite both the hearing and appeals processes. Section 109.002 was amended to provide that all termination appeals are to be “accelerated” and governed by the procedures for an accelerated appeal under the Texas Rules of Appellate Procedure.17 Section 263.405 was amended to require additional postjudgment and appellate steps regarding final orders involuntarily terminating parental rights.18 The stated intent of these amendments was, again, to accelerate the appeal process and thereby “help to minimize the time that a child has to be subject to lengthy and distressing court proceedings.”19 Specifically, section 263.405(b), added in 2001, provides:
Not later than the 15th day after the date a final order is signed by the trial judge, a party intending to appeal the order must file with the trial court a statement of the point or points on which the party intends to appeal. The statement may be combined with a motion for new trial.20
This court and several of our sister courts of appeals have recognized that the purposes of section 263.405(b) were to eliminate frivolous appeals in termination cases, reduce the costs associated with such appeals, and reduce appellate delays.21 However, we and other courts of appeals also held that failure to file a statement of points or to list a complaint in the statement of points does not deprive us of jurisdiction over the appeal22 nor neces[634]*634sarily waive review of an issue on appeal.23 Specifically, this court held that such failure does not constitute a waiver when the appellee does not establish prejudice, following the liberal approach adopted by the supreme court when an appellant has requested only a partial reporter’s record but has failed to file a statement of points as required by appellate rule 34.6(c).24
Expressing its disapproval of this line of cases as seeming to “effectively repeal” the statute’s effort to address postjudgment delay, the legislature enacted section 263.405(i), effective September 1, 2005, instructing us that we may not consider any issue not presented to the trial court in a timely filed statement of points.25 The House Bill Analysis for that statute states that cases interpreting section 253.405(b) have frustrated the legislature’s goal to speed up the postjudgment process by “bog[ging] down the [system] with mistakes” that could have been easily corrected at the trial level by the granting of a new trial.26 The Bill Analysis further states that section 263.405(i) clarifies the legislature’s intent by conclusively establishing that “the Legislature expects litigants to comply with Section 263.405(b)” because compliance as intended “would correct any wrongs 30 days after trial, as opposed to extending reversals months or years after trial.”27
b. Separation of Powers
A court will not pass on the constitutionality of a statute if the particular case before it may be decided upon independent alternative grounds.28 But section 263.405(i) by its own terms bars us from considering Betty’s issues challenging the constitutionality of that section as well as her second issue on the merits because those issues were not listed in her original statement of points. Nor are we at liberty to determine that any unconstitutionality was “harmless” because the statute says we may not “consider” Betty’s second issue to determine whether she would be entitled to prevail on the merits if the statute did not preclude us from reviewing her complaint.29 Therefore, we are directly confronted with the issue of the constitutionality of section 263.405(f).30
[635]*635We start with the presumption that the legislature intended to comply with the United States and Texas constitutions.31 If possible, we must interpret a statute in a manner that renders it constitutional.32 Mindful of these admonitions, we turn to the question of whether section 263.405(i) is unconstitutional as a violation of the Separation of Powers Clause. Since its enactment, several courts of appeals have questioned the practical application and constitutionality of the statute, but we are aware of no case that has addressed its constitutionality under the Separation of Powers Clause.33
Section I of article II of the constitution provides:
The powers of the Government of the State of Texas shall be divided into three distinct departments, each of which shall be confided to a separate body of magistracy, to-wit: Those which are Legislative to one; those which are Executive to another, and those which are Judicial to another; and no person, or collection of persons, being of one of these departments, shall exercise any power properly attached to either of the others, except in the instances herein expressly permitted.34
The Separation of Powers Clause is violated (1) when one branch of government assumes power more properly attached to another branch or (2) when one branch unduly interferes with another branch so that the other cannot effectively exercise its constitutionally assigned powers.35 Any attempt by one branch of government to interfere unduly with the powers of another is null and void.36 As stated in a landmark case on this subject by the Supreme Court of Texas:
The separation of powers was believed by Montesquieu, by Blackstone, and by American Constitution makers of the eighteenth century to be one of the chief and most admirable characteristics of the English Constitution.
A principle which is the very foundation of the government of the United States and of the several states must be deemed one essential to the preservation and liberties of the people, and should be thoughtfully and faithfully observed by all clothed with the powers of government.37
[636]*636The judicial power is vested in the courts created by the constitution and, as provided in the Separation of Powers Clause, is not subject to change by the legislature “except in the instances herein expressly permitted.”38 Article V, section 1 of the Texas constitution vests “[t]he judicial power of this State ... in one Supreme Court, in one Court of Criminal Appeals, in Courts of Appeals, in District Courts ... and in such other courts as may be provided by law.39 Article V, section 6(a) of the constitution expressly grants the courts of appeals appellate jurisdiction co-extensive with the limits of their respective jurisdictions, which shall extend to “all cases of which the District Courts or County Courts have original or appellate jurisdiction, under such restrictions and regulations as may be prescribed by law. Provided, that the decision of said courts shall be conclusive on all questions of fact brought before them on appeal or error.”40
Article V, section 6(a) of the constitution also grants courts of appeals “original or appellate jurisdiction, under such restrictions and regulations as may be prescribed by law.” 41 Thus, our jurisdiction over an appeal may arise from either (1) the general constitutional grant, or (2) a specific statutory grant of jurisdiction as may be prescribed by the legislature.42
The Department first argues that our jurisdiction in termination cases is purely statutory and not constitutional because the right to appeal in a termination suit in Texas is expressly granted by the family code.43 Thus, the Department contends, the legislature may place such restrictions on the right of appeal as it chooses. We disagree.44
Our judicial power is conferred by the constitution.45 Our constitutional jurisdiction extends to appeals in all cases of which the district courts have original jurisdiction, which includes termination cases46 Appeals in termination cases have [637]*637long predated section 109.002 of the family code and its predecessor statutes.47 Family code section 109.002(a) merely recognizes our existing appellate jurisdiction in termination cases, i.e., “as in civil cases generally.”48
The Department next posits that the legislature still retains the power to impose restrictions and regulations on our appellate jurisdiction, which it has done by enacting section 268.405®. This is so, the Department argues, because our constitutional jurisdiction is granted subject expressly to “such restrictions and regulations as may be prescribed by law.”49 Thus, the Department contends, our jurisdiction is not absolute but is subject to limitation by the legislature.
We agree that our constitutionally granted jurisdiction is not absolute. But neither is the legislature’s power to restrict and regulate the appellate courts’ jurisdiction unlimited.50 Specifically; “[i]t is [ ] when the functioning of the judicial process in a field constitutionally committed to the control of the courts is interfered with by the executive or legislative branches that a constitutional problem arises.”51 We recently acknowledged that the legislature may restrict and regulate our constitutional jurisdiction over appeals from orders terminating parental rights.52 But in the same paragraph, we pointed out that the legislature cannot interfere with our constitutionally granted powers and that any attempt to do so would be null and void.53 The legislature plainly may not interfere with the functions and powers of the judicial branch so as to usurp [638]*638those functions and powers.54
The Department also asserts that section 263.405(i) is a permissible restriction on our judicial power, relying upon cases holding that the legislature may not only restrict or limit but may even deny altogether the right of appeal. But Texas already provides the right of appeal from a judgment terminating parental rights.55 Where appellate court review is permitted, the avenues for appeal must be kept free of unreasonable restrictions that hinder the exercise of our power of appellate review.56 Moreover, restricting the individual right of appeal of a litigant is not the same as restricting our judicial power. While due process prevents undue restriction on parents in exercising their right of appeal, it is restrictions on our judicial power that implicate the doctrine of separation of powers.57
All but one of the cases relied upon by the Department merely involved questions of statutory construction of language of statutes limiting the right of appeal; in none of those cases was the separation of powers doctrine raised.58 The last case relied on by the Department, Rushing v. State, is also distinguishable.59 The court of criminal appeals held in that case that the claim in question was merely a “particular kind of jurisdictional claim of legislative creation” under the juvenile court system that had been created by the legislature, so that the legislature retained power to prescribe the requirement for preservation of error as to the claim without violating the Separation of Powers Clause.60 The court also based its hold[639]*639ing, in part, on its own precedent that rules of appellate procedure could not trump statutes in criminal cases.61 But terminations of parental rights are not criminal cases. And, as we have previously noted, both the district courts’ and the appellate courts’ power in parental termination suits is constitutional rather than statutory.62 And, finally, neither section 263.405(b) nor (i) is a preservation of error statute like the statute in Rushing.
The Department argues that section 263.405© does not interfere with the “appellate [c]ourt’s discretion or power to rule on issues once they are properly before the court. It merely creates a process which litigants must follow to bring an issue before the [c]ourt.” We agree that section 263.405® is intended as a procedural rule.63 But this is not the end of our inquiry.
Nothing in section 263.405® suggests that the legislature intended by that statute to substitute the statement of points for the rules of civil and appellate procedure in order to preserve error in cases involving involuntary termination of parental rights. No one would suggest that Betty could have preserved error regarding her complaint of the denial of an extension of the one-year dismissal deadline only after trial by listing it in a statement of points filed fifteen days after the final order was signed. Nothing in either (b) or © suggests that timely filing a statement of points listing all of the issues to be raised on appeal will bring an issue listed in that statement before the appellate court. A prospective appellant must still have timely and properly complied with all applicable rules of procedure governing preservation of error in order for any complaints to be considered on appeal. Contrary to the Department’s position, neither section 263.405©) nor © “creates a process which litigants must follow to bring an issue before the [appellate c]ourt.”
In order to be properly before the appellate court, any complaints must have been timely called to the trial court’s attention before or during trial (including complaints related to pleadings, voir dire, admissibility of evidence, charge errors, or improper jury argument), or they must be listed in a timely filed postjudgment motion (for complaints seeking rendition) or in a motion for new trial (for complaints seeking remand such as factual insufficiency of evidence to support jury findings and complaints that require evidence to be produced at the new trial hearing).64
The rules of civil and appellate procedure have the force and effect of [640]*640statutes and as binding supreme court decisions.65 Accordingly, we must continue to observe and follow those rules; we have no authority to deviate from them.66 Under appellate rule 47.1, a court of appeals must hand down a written opinion that addresses “every issue raised and necessary” to the final disposition of an appeal.67 Therefore, pursuant to appellate rule 33.1, we must address and decide the merits of Betty’s second issue because she properly preserved it for appeal by her motion for extension of the dismissal deadline that she timely presented and then re-urged prior to trial.68
Section 263.405© prohibits us from considering Betty’s second issue even though it was properly preserved. But for the reasons stated below, we hold that section 263.405© is void because it violates the Separation of Powers Clause of the constitution to the extent that it forecloses our power to review issues properly preserved for appeal because the statute unduly interferes with our substantive power as an appellate court to rehear and determine issues on the merits that were decided in the court below.69
The legislature may not “infringe upon the substantive power of the Judicial department under the guise of establishing ‘rules of court,’ thus rendering the separation of powers doctrine meaningless.”70 Even in the period before the Rule Making Act of 1939 when rules of procedure were prescribed by statute,71 the supreme court held that “[t]he legislature [may] regulate the procedure by which jurisdiction conferred by the constitution may be exercised ... and procedure in the appellate courts, but it [may] not substantially impair the constitutional jurisdiction granted [641]*641nor practically defeat its exercise.”72
In Meshell v. State, the court of criminal appeals was faced with whether the version of the Speedy Trial Act then in effect encroached upon the substantive powers of the judicial branch in violation of the Separation of Powers Clause or whether by that Act the legislature legitimately provided a statutory procedural rule to guide in enforcement of a substantive right.73 The court held the Act unconstitutional by imposing a deadline on readiness for trial by county attorneys, as members of the judicial branch, although the Act purported to establish only a procedural guideline for enforcement of a defendant’s right to a speedy trial.74
The court’s analysis in Meshell focused, first, on the nature of the legislative action complained of and, second, on whether that action encroached on the power of the judicial branch.75 The court first identified the substantive right the legislature intended to enforce by imposing procedural guidelines, i.e., the right to a speedy trial, but observed that, from its plain language, the Act was directed only at expediting the prosecutor’s preparation and readiness for trial, not at expediting actual commencement of trial.76 The court concluded the Act thus did not accomplish the stated objective, even incidentally, of speeding a case to trial, but only guaranteed a dismissal to the defendant if there was prose-cutorial delay in preparing for trial. In so doing, the court concluded, the legislature encroached upon the exclusive prosecutorial discretion of the county attorney and thereby violated the Separation of Powers Clause.77
In Williams v. State, the court of criminal appeals focused on the effect of legislative encroachment on the judicial power.78 The court held that a statute requiring a ninety-five percent remittitur of a judgment forfeiting bond if statutory requirements were met within two years after judgment, in effect, was a modification of a final judgment and thus violated the separation of powers provision because it usurped the judicial branch’s function and power over final judgments.79 In Armadillo Bail Bonds v. State, the court of criminal appeals considered a similar statute that the legislature apparently enacted in an attempt to circumvent the holding in Williams, limiting a trial court’s authority to enter a final judgment until eighteen months after a forfeiture was entered.80
The court in Armadillo Bail Bonds observed that certain judicial functions are so fundamental that courts alone may determine when and how those functions are to be exercised.81 The court concluded that [642]*642there must remain some realm of judicial “activity so fundamental and so inherent in its very nature as a court that to divest it of its absolute command within these spheres is to make meaningless the very phrase judicial power.”82 Looking to decisions of other states, the court found a consensus of opinion — with which it agreed — that when and how cases shall be decided may not be dictated by the legislature but are matters solely for the judicial branch of government.83
The Armadillo Bail Bonds court reasoned as follows: the statute would compel the trial court to refrain from exercising a part of its “core power,” i.e., entry of final judgment, for a year and a half; and if that requirement were valid, then “nothing prohibits the legislature from imposing an interminable delay in obtaining final judgment.”84 In short, if the statute were valid, then the legislature would have the power to “render the Judiciary impotent with respect to entry of final judgments;” therefore, the statute unduly interfered with the judiciary’s effective exercise of its constitutionally-assigned power and was invalid as a violation of the Separation of Powers Clause.85
We first apply the Meshell analysis to section 263.405(i). As we have seen, that section was added in an effort to enforce the requirement of a timely statement of points in order to give the trial court an opportunity to correct its own errors by granting a new trial, thereby minimizing postjudgment and appellate delays. We share the legislature’s concern with post-judgment and appellate delays as well as its desire to reduce the time children removed from their parents must spend in foster care. We also share its concern with eliminating frivolous appeals and reduction in costs, two other stated purposes of section 263.405(b) in requiring the statement of points.
But section 253.405® is not directed at those goals, even incidentally. Instead, it is directed at simply prohibiting exercise of our appellate power to review issues. Rather than expediting the postjudgment and appellate process and cutting down on delay, it merely guarantees the Department an affirmance of all errors not listed in a statement of points, regardless of merit. The consequence of sections 263.405(b) and (i) together is that, if complaints are not listed in a timely filed statement of points, even meritorious complaints otherwise timely and properly preserved for appeal under the rules are forever barred from appellate review.
Moreover, neither section 263.405(b) nor (i) expedites the postjudgment or appellate process; the appellate rules and the family code already provide for an accelerated appeal process for judgments terminating [643]*643parental rights.86 The fifteen-day filing deadline for a statement of points neither accelerates nor expedites any timetable for postjudgment motions or for the necessary steps for appeal. Because the termination order is a final judgment, the appealing party still has thirty days under rule of civil procedure 329b to file a motion for new trial, an additional fifteen days after the statement of points is due.87 The times for filing other postjudgment motions and for perfecting an appeal still begin with the signing of the final termination order, and the accelerated appellate timetable still begins to run from the date the final order is signed, with the notice of appeal still due twenty days after the order is signed,88 the reporter’s record and clerk’s record still due sixty days after the notice of appeal is filed,89 and the appellate briefing schedule still beginning twenty days thereafter.90
The House Bill Analysis for section 263.405(i) also states that the new section, by prohibiting courts of appeals from considering issues not included in the statement of points, accomplishes the purpose of allowing the trial court “to correct any errors within thirty days after trial or grant a new trial, thereby avoiding lengthy appeals.”91 But new section 263.405(i) does no such thing.92 Making the statement of points mandatory upon pain of waiver does not ensure errorless judgments nor eliminate the necessity for an appeal. Nothing in the statute provides any guarantee that filing a statement of points will cause a trial court to be any more likely to correct its errors or to grant a new trial so as to eliminate the requirement for an appeal than when error is timely and properly presented to the trial court pursuant to the rules of procedure. If a statement of points in the trial court sufficed to obtain correction of errors, our existence as an appellate court as contemplated by the constitution would be rendered totally unnecessary.
Thus, section 263.405(b) creates a dupli-cative procedural hurdle over and above the long-established procedural rules for preservation of error; yet compliance with that statute does not preserve error for appeal. The statute merely adds additional cost and delay instead of reducing it while section (i) ultimately precludes our review of claims that have otherwise been properly preserved, resulting in affirmance in otherwise meritorious appeals as well as frivolous ones.
Our existing civil trial and civil appellate procedural schemes designed and promulgated by the supreme court already carry out the stated goals of the legislature. The existing rules minimize delay, they assure that parties must bring every complaint of error to the attention of the trial court in a timely manner, and they provide the trial court ample opportunity at every [644]*644step of the trial proceedings to cure its own errors and grant new trials when needed, so as to eliminate unnecessary appeals. But they also allow meritorious claims to be reviewed and corrected on appeal.93
Why is the statutory mandate — that an issue cannot be considered on appeal if not listed in a timely filed statement of points — different from preservation of error requirements imposed by the rules of civil and appellate procedure? After all, doesn’t the statute, like the rules, provide that appellate courts cannot consider issues not properly and timely raised in the trial court? Yes, but there are significant differences. First, as already discussed above, a statement of points does not preserve error for appeal, unlike preservation of error rules. The statement of points only serves a purpose in the trial court to allow it to consider whether issues are frivolous. Second, unlike preservation of error rules that require presentation of a motion, objection, or request to and a ruling by the trial court, there is no requirement that the trial court even rule on the statement of points.
Third, appellate courts interpret and apply the rules of procedure promulgated by the supreme court liberally so as to resolve issues on the merits whenever possible.94 In contrast, by the statute clearly prohibiting appellate courts from considering any issue not listed in a statement of points, appellate courts are deprived of any discretion to allow consideration of issues even when literal application of the terms of the statute defeats the aim of resolving appeals on the merits.95 Finally, as the supreme court has pointed out, while the civil and appellate rules promulgated by that court do place restrictions upon the right of access to an appellate tribunal, those restrictions “serve to provide a more [645]*645orderly and efficient judicial system.”96 For the reasons so well articulated by our sister courts, we are unable to see how sections 268.405(b) or (i) serve to provide a more orderly or efficient judicial system.97 Thus, under the Meshell analysis, section 263.405(i) is not directed at the goals the legislature seeks to accomplish. Instead, it merely guarantees that the Department wins by blocking the exercise of our appellate judicial function. As in Meshell, under the guise of establishing a procedural rule by the statute in question, the legislature has unduly interfered with our substantive appellate powers.
This conclusion is reinforced by utilizing the Armadillo Bail Bonds approach. Section 263.405® interferes with our power to exercise discretion in determining whether to consider issues not listed in a statement of points, even in absence of prejudice to the Department. The statute bars our consideration of all issues not listed even when they were properly preserved for review under the rules of procedure. In effect, the legislature decides for us that complaints not listed in a timely statement of points are waived. In so doing, section 263.405(i) infringes upon our ability to exercise a “core power” reserved for the judicial branch by telling us not only how we must rule on issues brought before us but that we cannot consider those issues at all.98 We hold that section 263.405® is, therefore, void as a violation of the separation of powers provision of the Texas constitution.99 We sustain Betty’s third issue in part.
3. Review of denial of motion to extend dismissal deadline
Because section 263.405® is void, we are not barred by that statute from considering points that were not listed in a statement of points so long as they were properly preserved for appellate review. Thus, we are now able to turn to the merits of Betty’s second issue, whether the trial court erred by denying her motion to extend the dismissal deadline under section 263.401(b).
a. Factual background
On June 4, 2005, in response to a 9-1-1 call made by Betty, eleven-month-old T.W. was taken to the Cook Children’s Medical [646]*646Center emergency room, unconscious and suffering from severe head trauma. A CT scan revealed T.W. had suffered a parietal skull fracture with subdural and epidural bleeding. Dr. Tom Haddock, who saw T.W. in the emergency room, testified that her injuries were consistent with her head having been slammed against a hard object, and the amount of bleeding indicated extreme force had been used. Dr. Haddock also testified that he observed scabbed-over linear stripes on T.W.’s right forearm, consistent with her having been struck with a rope or wire. T.W. also had linear striping and bruising to her upper back. T.W. was admitted to the pediatric intensive care unit and remained there for almost a month.
On the same date that T.W. was admitted to the hospital, the Department took three-year-old D.W. to Cook Children’s for an evaluation because his sibling had been admitted to intensive care. D.W.’s body displayed numerous old scars on his back, buttocks, and hands, all indicative of physical abuse. Betty told a Department investigator that Stevie G., by whom she was eight months pregnant with another child, had inflicted all of the marks on D.W. and T.W. and that, during the eleven months she and Stevie had been together, Stevie had been hitting D.W. and T.W. with a switch or belt until he left marks. Betty later admitted to Detective Eel that her mother, Janice W., as well as Stevie, hit the children. Betty went on to tell the Department investigator that around 1:45 a.m. of the day T.W. was taken to the emergency room, Stevie had hit T.W.’s head against the wall twice, yelling at her to go to sleep. She also said Stevie had inflicted the linear marks on T.W.’s arm.
Betty told Detective Ezelle at least two different stories concerning T.W.’s injuries. She first said that T.W. woke up in the middle of the night, vomiting, and that she did not realize Stevie had injured T.W. Betty later said that T.W. woke up around 2:00 a.m. and began vomiting around 3:00 or 4:00 a.m. She also said Stevie hit T.W. with a belt, and when he put her back on a pallet on the floor, her head hit the wall more than once. When Detective Ezelle visited Betty’s house, he found an indentation in the wall above a pallet.
At the time of the termination hearing, T.W., then twenty-three months old, had just begun walking with the assistance of braces on both legs. T.W. suffers ataxia, which affects the parts of the nervous system that control balance and movement, and because her balance is so poor, she needs a compression suit to walk on her own. T.W. also suffers from frequent seizures, has problems swallowing clear liquids, and has some loss of vision. In July of 2005, Betty gave birth to S.G., who was placed in foster care the day after her birth. At the time of the termination hearing, all three children had been placed together in one foster home.100
April Hawkins was the Department caseworker assigned to Betty’s case. She testified that all three children had medical and physical issues. Hawkins said that Betty had stopped attending Department-funded counseling on March 23, 2006, about seven weeks before trial. Based on her observations of Betty with the children, Hawkins did not think Betty could raise the children on her own. During the visits, Betty would hold the baby and not interact with the other two children. Although Betty had completed a parenting-skills class, Hawkins said that she did not [647]*647see Betty use any such skills except on the baby. All three children were in pull-ups or diapers, and on one occasion it took Betty thirty minutes to change two diapers.
Hawkins testified that Betty had substantially complied with her service plan except for obtaining stable housing. One factor out of Betty’s control was the recent influx of hurricane victims, which made obtaining housing through the housing authority more difficult. Betty lived with her mother, Janice, and Betty had identified Janice as one of the people who was hitting the children. Also, Janice had failed to protect Betty from sexual abuse by Betty’s stepfather. According to Betty, who said she was a teen at the time, Janice was aware of the abuse but did nothing to stop it. Moreover, Hawkins testified that Betty continued to see Stevie, the man who had injured T.W.
As part of her service plan, Betty underwent an assessment at MHMR, but MHMR denied her any services because Betty functioned below the minimum level necessary to qualify for services. Hawkins testified that the Department thought Betty should make another attempt to obtain MHMR services, and she thought that Betty had an appointment to be reassessed in the month following trial.
b. Standard of review
Because an extension of the dismissal date is similar to a continuance and because section 268.401(b) does not indicate which appellate standard of review to apply, we apply the abuse of discretion standard.101
To determine whether a trial court abused its discretion, we must decide whether the trial court acted without reference to any guiding rules or principles; in other words, we must decide whether the act was arbitrary or unreasonable.102 Merely because a trial court may decide a matter within its discretion in a different manner than an appellate court would in a similar circumstance does not demonstrate that an abuse of discretion has occurred.103
An abuse of discretion does not occur where the trial court bases its decisions on conflicting evidence.104 Furthermore, an abuse of discretion does not occur as long as some evidence of substantive and probative character exists to support the trial court’s decision.105
c. Discussion
Betty argues that the trial court abused its discretion by failing to find that her upcoming appointment with MHMR and the influx of hurricane victims — a factor beyond Betty’s control that made it impossible for her to find stable housing through the housing authority — were extraordinary circumstances that justified an extension of the dismissal deadline.106 We disagree.
The trial court first considered Betty’s motion to extend the dismissal deadline on March 28, 2006. But there is no record of that hearing or the evidence. Because no record was made of the March 28 hearing, [648]*648we must presume that the evidence supported the trial court’s ruling and, therefore, we hold that the trial court did not abuse its discretion in denying Betty’s pretrial motion.107
Betty re-urged her motion at the beginning of the final hearing. Betty presented no evidence pertaining to the motion, but trial counsel asserted that Betty needed a 180-day extension because MHMR had provided her with the name of an entity that was willing to provide services to her beginning a month later and because “she’s still receiving difficulty from the Housing Authority in terms of having an apartment available to her.” Because Betty presented no evidence when she re-urged her motion, she cannot show that the trial court abused its discretion when it denied her motion.108
To the extent Betty’s second issue encompasses the overruling by operation of law of her motion for new trial, in which she argued that the trial court erred by failing to grant her 263.401(b) motion, after the trial court heard evidence pertinent to her motion to extend the dismissal deadline, we hold that the trial court did not abuse its discretion. The evidence presented to the trial court during the final hearing did not render the denial of the motion arbitrary or unreasonable. Hawkins testified that, contrary to counsel’s pretrial assertion, Betty’s upcoming appointment with MHMR was merely for reassessment, not for definite placement in a service program. In light of all of the other evidence presented at trial, we cannot say that the trial court abused its discretion by failing to find extraordinary circumstances that justified a 180-day extension of the dismissal deadline. We overrule Betty’s second issue.
III. Conclusion
Having sustained Betty’s third issue in part and overruled it in part, having overruled her first and second issues, and not reaching her fourth issue, we affirm the trial court’s final order terminating her parental rights to D.W., T.W., and S.G.
