OPINION
HAYES, Judge.
The appellant, Ronald Rickman, appeals the post-conviction court’s summary dismissal of his third petition for post-conviction court relief. In 1978, the appellant was convicted of first degree murder and sentenced to death for the contract killing of Deborah Lee Groseclose, the wife of his co-defendant, William Groseclose. In 1981, our supreme court affirmed the appellant’s conviction. State v. Groseclose and Rickman, 615 S.W.2d 142 (Tenn.), cert. denied, 454 U.S. 882, 102 S.Ct. 367 (1981). In 1982, the appellant filed his first petition for post-conviction relief, which the post-conviction court denied following the appointment of counsel and a full evidentiary hearing. This court affirmed the lower court’s judgment. Groseclose and Rickman v. State, No. 9 (Tenn.Crim.App. at Nashville, February 16, 1984). Our supreme court denied the appellant permission to appeal, and the United States Supreme Court denied certiorari. Rickman v. Tennessee, 469 U.S. 963, 105 S.Ct. 363, 83 L.Ed.2d 299 (1984). In 1985, the appellant filed a Petition for Writ of Habeas Corpus in federal district court. Subsequently, in 1989, while his habe-as corpus petition was still pending in federal [690]*690district court, the appellant filed his second petition for post-conviction relief. In 1990, the post-conviction court dismissed the appellant’s petition without an evidentiary hearing. This court affirmed the lower court’s judgment. Rickman v. State, No. 15, 1991 WL 174141 (Tenn.Crim.App. at Jackson, September 11, 1991), perm, to appeal denied, (Tenn. 1992). In 1994, pursuant to the appellant’s motion for partial summary judgment of his habeas corpus petition, the federal district court vacated the appellant’s sentence of death. Rickman v. Dutton, 854 F.Supp. 1305 (M.D.Tenn.1994). Thereafter, in a separate opinion, the federal district court vacated the appellant’s conviction for first degree murder. Rickman v. Dutton, 864 F.Supp. 686 (M.D.Tenn.1994). The federal district court’s opinions are now on appeal before the United States Court of Appeals for the Sixth Circuit.
Nevertheless, on April 13, 1995, the appellant filed the instant petition for post-conviction relief, his third petition.1 On May 24, 1995, the appellant filed before the post-conviction court a “Motion to Abate Proceedings,” pending resolution of the federal appeal.2 The appellant asserted that affir-mance by the Sixth Circuit of the federal district court’s decisions would render the instant post-conviction proceedings moot. On July 7, 1995, the appellant further submitted to the post-conviction court a motion for appointment of counsel. On March 6, 1996, the post-conviction court denied the appellant’s motions and dismissed the appellant’s petition, finding that the appellant had raised no claims in his third petition for post-conviction relief that had not been previously determined or waived.3
On appeal, the appellant presents the following issues for our consideration:
(1)Whether the appellant is entitled to a new sentencing hearing pursuant to our supreme court’s decision in State v. Middlebrooks, 840 S.W.2d 317 (Tenn. 1992);
(2) Whether the appellant was denied his right, under the Tennessee constitution, to a unanimous jury verdict;
(3) Whether the appellant was involuntarily administered “mind-dulling drugs” during his trial in violation of the United States Supreme Court’s holding in Riggins v. Nevada, 504 U.S. 127, 112 S.Ct. 1810, 118 L.Ed.2d 479 (1992);
(4) Whether the death penalty infringes upon the appellant’s fundamental right to life in violation of the Tennessee and United States constitutions;
(5) Whether the State’s plea offer of a life sentence infringed upon the appellant’s right to trial and resulted in the arbitrary imposition of a sentence of death in violation of the Tennessee and United States constitutions;
(6) Whether the appellant was sentenced by an impartial jury in violation of the Tennessee and United States constitutions;
(7) Whether, in violation of the state and federal constitutions, the grand jury was tainted by gender discrimination in the selection of grand jury fore persons in Shelby County;
(8) Whether the appellant was denied effective assistance of counsel at trial or in any subsequent proceeding in violation of the state and federal constitutions.
Following a review of the record, we affirm the post-conviction court’s judgment.
ANALYSIS
The appellant contends that the post-conviction court erred in dismissing his peti[691]*691tion for post-conviction relief.4 The State contends that the appellant’s petition is time-barred by the statute of limitations. Tenn. Code Ann. § 40-30-102 (1990)(“[a] prisoner in custody under sentence of a court of this state must petition for post-conviction relief ... within three years of the date of the final action of the highest state appellate court to which an appeal is taken”). Our supreme court affirmed the appellant’s conviction in 1981, prior to the enactment of the three year statute of limitations and prior to the effective date of the statute on July 1, 1986. The new limitations period applied to existing causes prospectively from this effective date. Abston v. State, 749 S.W.2d 487, 488 (Tenn.Crim.App.1988). See also Sands v. State, 903 S.W.2d 297, 301 (Tenn.1995)(the supreme court acknowledged the “Abston rule”). Accordingly, the statute of limitations expired in the appellant’s ease on July 1,1989.
Regardless of the applicability of the statute, under Burford v. State, 845 S.W.2d 204 (Tenn.1992), and Sands, 903 S.W.2d at 297,5 to the various issues raised by the appellant, the appellant asserts that the State did not rely upon the statute of limitations when arguing before the post-conviction court and cannot rely upon this defense on appeal. In its answer to the appellant’s petition and in proceedings before the post-eonviction court, the State argued that the court should dismiss the appellant’s petition, because the appellant’s case was pending before the United States Court of Appeals for the Sixth Circuit. Inexplicably, in its response, the State did not allege the expiration of the statute of limitations, nor did it raise the defenses of waiver and previous determination or address the merits of the appellant’s petition.
Generally, with respect to those seeking post-conviction relief, this court will not address post-conviction issues that were not raised in the petition or addressed in the post-conviction court. Brown v. State, 928 S.W.2d 453, 457 (Tenn.Crim.App.), perm, to appeal denied, (Tenn.1996)(citing State v. Smith, 814 S.W.2d 45, 49 (Tenn.1991)). The appellant correctly observes in his brief that this court has similarly declined to adopt a position of the State taken for the first time on appeal. State v. Perry, No. 03C01-9401-CR-00016, 1995 WL 433319 (Tenn.Crim.App. at Knoxville), perm, to appeal denied, (Tenn.1995). Moreover, the statute of limitations is an affirmative defense which the State must plead and prove. Smith v. State, 873 S.W.2d 5, 6 (Tenn.Crim.App.1993). Failure to do so constitutes a waiver of the defense. Id. (citations omitted). See also Sandusky v. State, No. 01C01-9404-CC-00142, 1995 WL 84030 (Tenn.Crim.App. at Nashville, March 2, 1995)(a statute of limitations defense may not be raised for the first time on appeal). The post-conviction court may raise the issue sua sponte. Id. See also Handley v. State, 889 S.W.2d 223, 224 (Tenn.Crim.App.1994). However, in the instant case, the court did not address this defense.
Nevertheless, in Sands, 903 S.W.2d at 299, our supreme court, in the context of Tenn. R. Civ. P. 8.03’s specific pleading requirement, held that this court did not err in applying the statute of limitations to the appellant’s coram nobis claim, despite the State’s failure to specifically plead the period of limitations applicable to coram nobis actions, either in its motion to dismiss the appellant’s petition for a writ of coram nobis and/or post-conviction relief or at the hearing before the trial court. The State - did cite the statute of limitations applicable to post-conviction petitions. Id. Accordingly,, the court concluded [692]*692that the appellant had received fair notice of the defense. Id. The supreme court observed:
Although Tenn. R. Civ. P. 8.03 does require that a statute of limitations defense be specifically pleaded, it is well settled that failure to do so does not result in a waiver of the defense if the opposing party is given fair notice of the defense and an opportunity to rebut it. In other words, the purpose of the specific pleading requirement is to prevent a party from raising a defense at the last moment and thereby prejudicing the opposing party’s opportunity to rebut the defense.
Id. (citations omitted). In Smith, 873 S.W.2d at 6-7, this court suggested, consistent with the above rationale, that when a defense has not been pled, but the petitioner has raised the issue in his own pleadings, there is no waiver. In the instant case, as pointed out by the State, the appellant addressed the statute of limitations defense in his petition for post-conviction relief and in his brief on appeal. Additionally, appellant’s counsel raised the issue of the statute of limitations before the post-conviction court when arguing before the court that the appellant’s petition should- not be dismissed. Appellant’s counsel conceded that the statute of limitations had already run, but cited exceptions to application of the statute. These facts are distinguished from those in Perry. The proof reveals that the appellant was clearly aware of the statute of limitation and its importance. Thus, the State’s failure to specifically plead the defense of statute of limitation did not prejudice the appellant. Accordingly, the State may, on appeal, rely upon the defenses of statute of limitation, waiver, and previous determination in support of its position.
However, the appellant contends that the post-conviction court failed to enter specific findings as to each issue raised by the appellant in his petition. In effect, the appellant challenges the post-conviction court’s compliance with Tenn.Code Ann. § 40-30-118(b)(1990). Tenn.Code Ann. § 40 — 30—118(b) provides:
Upon the final disposition of every petition, the court shall enter a final order, and ... shall set forth in the order or a written memorandum of the case all grounds presented and shall state the findings of fact and conclusions of law with regard to each such ground.
This court has observed that, “[ajlthough this requirement has been determined to be mandatory, the failure of the trial judge to abide by the requirement does not always mandate a reversal of the trial court’s judgment.” State v. Swanson, 680 S.W.2d 487, 489 (Tenn.Crim.App.1984) (citations omitted). See also Swanson v. State, 749 S.W.2d 731, 736 n. 3 (Tenn.1988). Noncompliance by the posteon-viction court does not warrant a reversal if the record is sufficient to effectuate a meaningful appellate review. Brown v. State, No. 03C01-9107-CR-00233, 1992 WL 143878 (Tenn.Crim.App. at Knoxville, June 26,1992). Even if not ideal in form, the order of dismissal in this case does set forth the reasons for the post-conviction court’s dismissal of the appellant’s petition. “[Wjhere the record of the proceedings contains the reasons of the trial judge for dismissing the petition, the record is sufficient to effectuate meaningful appellate review.” Watkins v. State, No. 1121, 1989 WL 106974 (Tenn.Crim.App. at Knoxville, September 18, 1989).
Of course, we must still determine if the post-conviction court properly dismissed the appellant’s petition without appointing counsel and without an evidentiary hearing. This court has observed that there is a discernible trend toward appointing counsel to assist pro se appellants in post-conviction proceedings, providing opportunities to amend petitions, and allowing evidentiary hearings.6 Carmley v. State, No. 03C01-9305-CR-00167, 1994 WL 7086 (Tenn.Crim.App. at Knoxville, January 13, 1994). Nevertheless, “a clear but patently non-meritorious petition may be dismissed summarily,” without the appointment of counsel or an evidentiary hearing. Martucci v. State, 872 [693]*693S.W.2d 947, 949 (Tenn.Crim.App.1993); Cureton v. Tollett, 477 S.W.2d 233, 236 (Tenn.Crim.App.1971). A petition sets forth a colorable claim if it alleges facts showing that the conviction resulted from an abridgment of a constitutional right and demonstrates that the ground for relief was not previously determined or waived. Carmley, No. 03C01-9305-CR-00167.
We must therefore determine whether the appellant’s claims have been waived or previously determined. Tenn. Code Ann. § 40-30-112 (1990) provides:
A ground for relief is ‘previously determined’ if a court of competent jurisdiction has ruled on the merits after a full and fair hearing.... A ground for relief is “waived’ if the petitioner knowingly and understandingly failed to present it for determination in any proceeding before a court of competent jurisdiction in which the ground could have been presented.
Initially, the record conclusively demonstrates that the appellant’s claim of ineffective assistance of counsel has been previously determined.7 The appellant contends, however, that any waiver was not knowing and understanding. See Tenn.Code Ann. § 40-30-112(b)(l). Moreover, he asserts that the objective standard of waiver articulated by the supreme court in House, 911 S.W.2d at 705, should not be “retroactively” applied to his case. He contends that such application would violate due process and ex post facto provisions of the Tennessee and United States Constitutions.
In House, our supreme court concluded that “[w]aiver in the post-conviction context is to be determined by an objective standard under which a petitioner is bound by the action or inaction of his attorney.” Id. at 714. However, in articulating this objective standard of waiver, the court observed that “Tennessee eases dealing generally with the concept of waiver in the post-conviction context apply an objective standard and impute the conduct of counsel to their clients.” Id. at 713. The court then applied this standard to the appellant in that case. In Melson v. State, No. 02C01-9402-CR-00023, 1996 WL 422565 (Tenn.Crim.App. at Jackson), perm, to appeal denied, (Tenn.1996), in its order denying the appellant’s petition for a rehearing, this court rejected the appellant’s argument that the waiver standard set forth in House should not be applied retroactively “ ‘to a petitioner who has relied on the plain language of the post-conviction statute.’” Indeed, we noted that relevant case history indicated that the statute, prior to the supreme court’s opinion in House, did not require personal waiver. Id. See also O’Guinn v. State, No. 02C01-9510-CC-00302 n. 1, 1997 WL 210890 (Tenn.Crim.App. at Jackson, April 29, 1997)(in applying House, this court observed that “[w]hile it is true that House was not issued until three months after the trial court’s dismissal of Appellant’s claim, the concept of an objective waiver standard was well-established prior to that ruling”). Thus, we must reject the appellant’s argument that House altered the situation of the appellant to his disadvantage. State v. Bragan, 920 S.W.2d 227, 241 (Tenn. Crim.App.1995), perm, to appeal denied, (Tenn.1996)(citing State v. Pearson, 858 S.W.2d 879, 882 (Tenn.1993)). See also State v. Ricci, 914 S.W.2d 475, 480 (Tenn.1996)(“[a]n ex post facto law contains two critical elements ... [fjirst, the law must apply to events occurring before its enactment; second, it must disadvantage the of[694]*694fender affected by it”). The supreme court’s decision in House did not change the law, but merely clarified existing law. Accordingly, application of the objective waiver standard to the appellant’s case violates neither ex post facto nor due process provisions of the Tennessee and United States Constitutions.8
Even in the context of an objective waiver standard, the appellant contends that several issues could not have been presented in any earlier proceeding. Tenn.Code Ann. § 40 — 30—112(b)(1). Clearly, “the waiver provision cannot logically or legally ‘apply to a defense [or grounds for relief] ... which did not exist and could not have been asserted by the most diligent counsel at the [prior] hearing.’” Swanson, 749 S.W.2d at 735 (citing Pruett v. State, 501 S.W.2d 807, 809 (Tenn.1973)). See also Burford, 845 S.W.2d at 208 (“[b]efore a state may terminate a claim for failure to comply with procedural requirements ..., due process requires that potential litigants be provided an opportunity for the presentation of claims at a meaningful time and in a meaningful manner”). Additionally, Tenn.Code Ann. § 40-30-105 permits a petitioner to rely upon “a right that was not recognized as existing at the time of the trial if either constitution requires retrospective application of that right.”
Nevertheless, we conclude that the record supports the post-conviction court’s finding that the appellant has waived the following issues:9 whether the appellant was denied his right, under the Tennessee constitution, to a unanimous jury verdict; whether the death penalty infringes upon the appellant’s fundamental right to life in violation of the Tennessee and United States constitutions; whether the State’s plea offer of a life sentence infringed upon the appellant’s right to trial and resulted in the arbitrary imposition of a sentence of death in violation of the Tennessee and United States constitutions; whether the appellant was sentenced by an impartial jury in violation of the Tennessee and United States constitutions; and whether, in violation of the state and federal constitutions, the grand jury was tainted by gender discrimination in the selection of grand jury forepersons in Shelby County.10
[695]*695A. MIDDLEBROOKS CLAIM
The appellant has not waived his argument that, in violation of our supreme court’s decision in Middlebrooks, 840 S.W.2d at 317, the State relied upon the felony murder circumstance to both prove first degree murder and to render the appellant death eligible. In Barber v. State, 889 S.W.2d 185 (Tenn.1994), cert. denied, U.S. , 115 S.Ct. 1177 (1995), the supreme court held that the decision in Middlebrooks announced a new rule that should be applied retroactively pursuant to Meadows, 849 S.W.2d at 748. See also Sample v. State, No. 02C01-9505-CR-00131,-00139,1996 WL 551754 (Tenn.Crim. App. 1996)11 Nevertheless, a review of the record reveals that the jury returned a verdict of guilt as to count one of the indictment. Count one of the indictment charged the appellant with “feloniously, wilfully, deliberately, maliciously and premeditatedly Kill[ing] and Murderfing]” the victim. Accordingly, the indictment only encompassed premeditated first degree murder or what was referred to as common law murder. See Tenn.Code Ann. § 39-2402(a)(1977). Thus, Middlebrooks is inapplicable12
[696]*696B. FORCED MEDICATION
The appellant next contends that, in violation of his due process rights, he was forcibly administered “mind-dulling” medication during his trial. In his first post-conviction petition, filed in 1982, the appellant asserted that he was incompetent to stand trial as a result of the State’s administration of Meprobamate and Dalmane during trial. On appeal, this court concluded that the record did not preponderate against the trial court’s finding to the contrary. Groseclose and Rickman, No. 9. In 1985, the appellant filed a federal writ of habeas corpus alleging, inter alia, that “he was unconstitutionally administered Meprobamate and Dal-mane by the State at critical stages of his trial.” Rickman, 864 F.Supp. at 712. The appellant’s second post-conviction petition filed in 1989, and while the federal writ was still pending, alleged no claim of forced medication. In 1994, the federal district court for the Middle District of Tennessee, relying upon Riggins v. Nevada, 504 U.S. 127, 112 S.Ct. 1810, 118 L.Ed.2d 479 (1992),13 concluded that, because the appellant had been “administered drugs which cause drowsiness and may inhibit their ability to follow the proceedings, due process requires a showing that such medication is necessary to accomplish an essential state policy.” Rickman, 864 F.Supp. at 713. In April 1995, the appellant, relying upon Riggins as a new rule of law, filed the instant petition alleging, inter alia, that he was “involuntarily administered mind-dulling drugs during the trial” in violation of his state and federal due process rights.14
[697]*697The existence of a constitutional right to refuse involuntarily administered medication grounded upon a liberty interest under the due process clause of the Fourteenth Amendment is undisputed. In Washington v. Harper, 494 U.S. 210, 221, 110 S.Ct. 1028, 1036, 108 L.Ed.2d 178 (1990), the Supreme Court recognized the existence of a “significant liberty interest [of a convicted prisoner] in avoiding the unwanted administration of anti-psychotic drugs.”15 The Court also stated: “The forcible injection of medication into a nonconsenting person’s body represents a substantial interference with that person’s liberty.” Id. at 229, 110 S.Ct. at 1041. Although the Court refused to find an absolute liberty interest of a competent person to refuse psychotropic drags, it recognized that the substantive protections of the Due Process Clause, under certain circumstances, limit the forced administration of psychotropic drags to inmates. Id. at 243, 110 S.Ct. at 1048.
In Riggins v. Nevada, 504 U.S. 127, 135, 112 S.Ct. 1810, 1815, 118 L.Ed.2d 479 (1992), the Supreme Court applied the Fourteenth Amendment principles of Harper to the pretrial and trial setting for detained defendants.16
Although the Supreme Court’s announcement in Riggins was perhaps new to the appellant when he filed his third post-conviction petition, Riggins created neither a new nor novel constitutional rule of law.17 See Riggins, 504 U.S. at 151, 112 S.Ct. at 1823 (Thomas, J., dissenting) (liberty interest recognized in Harper); see also State v. Van Orden, 64-7 N.E.2d 641, 644 (Ind.App. 4 Dist. 1995) (“[T]he holding in Riggins does not apply retroactively to Van Orden’s trial result.” Teague, 485 U.S. at 933, 108 S.Ct. at 1106). Cf. Heffernan v. Norris, 48 F.3d 331, 334 (8th Cir.1995) (holding that Riggins does not present novel constitutional issues). But [698]*698see Giannini v. State, No. 02C01-9603-CR-00091, 1997 WL 11267 (Tenn.Crim.App. at Jackson, Jan. 15, 1997). Clearly, the liberty interest arising from the involuntary administration of medication was recognized in Harper, which was decided in 1990.18 The appellant first raised this issue in the state courts in his third postconviction petition filed in 1995. Accordingly, we find the issue of forced medication barred by the applicable three year statute of limitations.
Notwithstanding our holding that the appellant’s forced medication claim is time barred, we are also compelled to note that the instant case does not invoke the due process protections afforded by Harper and Riggins. The Supreme Court, in Riggins, narrowly defined those circumstances under which the due process procedures set forth in Harper are required; the threshold determination being whether the appellant was forcibly medicated, i.e., whether the medication was unwanted, compelled, over objection, or involuntary, and not whether the State may administer medication.19 Riggins, 504 U.S. at 133, 112 S.Ct. at 1814. Accord Magwood v. State, 689 So.2d 959, 985 (Ala.Cr.App.1996), cert. denied, (Ala.1997); Ferguson v. Singletary, 632 So.2d 53, 56 (Fla.1993); Van Orden, 647 N.E.2d at 644; Ex Parte Thomas, 906 S.W.2d 22, 24 (Tex.Crim.App.1995). Although no evidentiary hearing was held in the instant case, the proof in the record from the 1982 post-conviction proceeding does not reflect that the medication received by the appellant was involuntary or forced upon him. Indeed, the findings of fact of the federal district court indicate that the attending psychiatrist informed the appellant as to the nature and identity of the medication prior to its administration. Rickman, 864 F.Supp. at 713. Moreover, there is no indication that the appellant, at any time, objected to being medicated. In a post-conviction petition, the appellant must establish his allegations by a preponderance of the evidence. McBee v. State, 655 S.W.2d 191, 195 (Tenn. Crim.App.1983). However, he fails to show anywhere in the record that he was forced to take the medication or that there was even an objection to his being medicated.20 Thus, we conclude that the Fourteenth Amendment implications addressed in Harper and Rig-gins have no application to the case before us. See Riggins, 504 U.S. at 133, 112 S.Ct. at 1814. Accordingly, the appellant’s due process contention is without merit.
The remaining issue, thus, involves the appellant’s Sixth Amendment right to counsel as observed in Riggins. “Competence to stand trial is rudimentary, for upon it depends the main part of those rights deemed essential to a fair trial, including the right to effective assistance of counsel, the rights to summon, to confront, and to cross-examine witnesses, and the right to testify on one’s own behalf or to remain silent without penalty for doing so.” Riggins, 504 U.S. at 139-40, 112 S.Ct. at 1817 (Kennedy, J., concurring) (citing Drope v. Missouri, 420 U.S. 162, 171-172, 95 S.Ct. 896, 903-904, 43 L.Ed.2d 103 (1975)). Accord Pate v. Robinson, 383 U.S. 375, 86 S.Ct. 836, 15 L.Ed.2d 815 (1966); State v. Stacy, 556 S.W.2d 552 (Tenn.Crim.App.1977); Mackey v. State, 537 S.W.2d 704 (Tenn.Crim.App.1975). However, the mere fact that the appellant was receiving medication during the course of a trial does not per se render him incompetent. See generally State v. DeAngelis, 200 Conn. 224, 511 A.2d 310 (1986); State v. Hampton, 253 La. 399, 218 So.2d 311 (1969); People v. Hardesty, 362 N.W.2d 787 (Mich.App.1984). [699]*699The appellant’s competency was previously litigated in his first post-conviction petition. Groseclose and Rickman, No. 9. As such, this issue has been previously determined and is without merit.
For the foregoing reasons, the judgment of ■ the post-conviction court dismissing the appellant’s petition is affirmed.
