WIGGINS, J.
*525¶ 1 Michael Gehrke was charged with second degree murder, predicated on second degree assault, for the death of Christopher Pineyro. Immediately before the State rested its case, the trial court allowed the State to amend its charges to include first degree manslaughter. The jury found Gehrke guilty of first degree manslaughter but not second degree murder.
¶ 2 Gehrke asks us to order the trial court to vacate his conviction for first degree manslaughter and dismiss with prejudice, arguing that allowing the amendment violated his constitutional right to be informed of the charges against him. We hold that allowing the State to amend its charge after completing its case in chief and immediately prior to resting violated Gehrke's constitutional right. We agree with Gehrke and reverse the decision of the Court of Appeals and remand to the trial court for vacation of his conviction, dismissal of the first degree manslaughter charge with prejudice, and further proceedings consistent with this Opinion.
FACTS AND PROCEDURAL HISTORY
¶ 3 Michael Gehrke was convicted of first degree manslaughter for the death of Christopher Pineyro, who died after being stabbed in a street fight with Gehrke. The two men had a history of conflict. At trial, the opposing sides offered conflicting accounts of the fight. According to Gehrke, he had just arrived at a friend's house in a vehicle driven by his girlfriend when Pineyro rode up to him on a bicycle. Pineyro stated that he had "something" for Gehrke and stopped his bicycle. Pineyro then reached behind himself and began to "shed his things." Gehrke reacted and kicked Pineyro's bike frame, which hit Pineyro in the leg. Pineyro and the bike fell to the ground together.
¶ 4 When Pineyro stood up, he was wielding a hammer. Gehrke drew a pocketknife. Pineyro began swinging the hammer at Gehrke, and Gehrke backed away. Pineyro advanced, and Gehrke retreated approximately 17 feet, toward a fence. Gehrke testified that he saw no opportunity to get any farther back and that "I thought that if I didn't do something, he would - he would back me up against the fence and hit me with the hammer." Gehrke jabbed at Pineyro twice with the knife, fatally wounding Pineyro in the neck. The police arrived and Gehrke admitted to striking Pineyro, saying, "I'm the guy. I stabbed him and it was self-defense."
¶ 5 The State charged Gehrke with second degree felony murder predicated on second degree assault. Clerk's Papers (CP) at 1. On the first day of trial, the prosecutor stated that the State was considering amending the charges to include first degree manslaughter as an alternative charge but noted that he was not currently seeking such an amendment. The prosecutor told the trial court, "I don't think that it would be prejudicial [to amend the charge], and it's a lesser offense.[1 ][The defense was] not in favor of that [amendment], therefore, I'm not going to submit that, but I did put them on notice that, at the conclusion of the State's case, I may be moving for that to be charged in the alternative."
¶ 6 After the State called its last witness but before it had formally rested, the prosecutor moved to amend the information to add a manslaughter charge. The State made clear that it intended to rest even if the amendment was not allowed ("The State does intend on. resting [regardless] of the Court's decision [to allow the amendment] in this *526case."). Defense counsel objected to the prosecutor's motion to amend, on the grounds that manslaughter is not a lesser included offense of felony murder and that Gehrke did not mount a defense to manslaughter, which requires an element of recklessness not required for felony murder.
¶ 7 The trial court granted the State's motion to amend the information. The court explained that Gehrke's possible defense strategy against a first degree manslaughter charge was "essentially the same" as the defense he had presented to the second degree murder charge. It is unclear from the record whether the trial court believed that the manslaughter charge was a lesser included offense of the original felony murder charge.
¶ 8 The jury was apparently unable to agree as to whether Gehrke was guilty of second degree murder.2 It found Gehrke guilty of first degree manslaughter.
¶ 9 Gehrke appealed. The Court of Appeals affirmed the trial court, holding that, under CrR 2.1(d), Gehrke could not demonstrate prejudice because his defense at trial was self-defense and that would have also been his defense to the amended charge. Gehrke petitioned this court for review, which we granted.
STANDARD OF REVIEW
¶ 10 We review a trial court's ruling on a proposed amendment to an information for abuse of discretion. State v. Lamb, 175 Wash.2d 121, 130, 285 P.3d 27 (2012) (citing State v. Schaffer, 120 Wash.2d 616, 621-22, 845 P.2d 281 (1993) ).
ANALYSIS
¶ 11 The trial court violated Gehrke's constitutional rights by allowing the State to add an alternative charge against Gehrke after it finished its case in chief and immediately before it rested.
I. Criminal defendants are entitled to receive notice of the nature of the charges and an opportunity to present a defense
¶ 12 It is a central right, provided in our constitution, that "[i]n criminal prosecutions the accused shall have the right ... to demand the nature and cause of the accusation against him." WASH. CONST. art. I, § 22. Pursuant to this right, "[t]he accused, in criminal prosecutions, has a constitutional right to be apprised of the nature and cause of the accusation against him. ... This doctrine is elementary and of universal application, and is founded on the plainest principle of justice." State v. Ackles, 8 Wash. 462, 464-65, 36 P. 597 (1894). The "accused must be informed of the charge he is to meet at trial and cannot be tried for an offense not charged." State v. Carr, 97 Wash.2d 436, 439, 645 P.2d 1098 (1982). Thus, "defendants have a right to be fully informed of the nature of accusations against them so that they may prepare an adequate defense. This right is satisfied when defendants are apprised with reasonable certainty of the accusations against them." State v. Leach, 113 Wash.2d 679, 695, 782 P.2d 552 (1989) (citations omitted).3
A. Criminal rules that allow for midtrial amendments operate within the confines of the constitution and cannot be read to contravene the constitution
¶ 13 The constitutional rights created by article I, section 22 inherently limit *527when and whether the State may make midtrial amendments to its information. State v. Olds, 39 Wash.2d 258, 261, 235 P.2d 165 (1951) (holding that "a new count charging a different crime ... would contravene Art. I, § 22, of the state constitution"). Thus, although CrR 2.1(d) -used here by the State to amend its information midtrial-provides that "[t]he court may permit any information or bill of particulars to be amended at any time before verdict or finding if substantial rights of the defendant are not prejudiced," this rule is inherently limited by article I, section 22. State v. Pelkey, 109 Wash.2d 484, 490, 745 P.2d 854 (1987) (referring to what was then CrR 2.1(e) but is now 2.1(d) ).
¶ 14 Courts of this state have long made clear that CrR 2.1 (d) is thus limited by our constitution. See, e.g., State v. Lutman, 26 Wash. App. 766, 768, 614 P.2d 224 (1980). In Lutman, the defendant was originally charged with hit-and-run and failure to yield. Id. at 767, 614 P.2d 224. At the conclusion of evidence, the trial court granted "a motion to amend the complaint to negligent driving." Id. Lutman was convicted of negligent driving and appealed. Id. The relevant criminal rule in effect at the time permitted an information " 'to be amended at any time before judgment' " if the amendment did not prejudice the defendant. Id. at 768, 614 P.2d 224 (quoting JTR (Justice Court Traffic Rules) 3.04). Nevertheless, the Court of Appeals held that this rule "cannot bear an interpretation which would contravene [article I, section 22]" of the constitution and that "[a]n amendment during trial stating a new count charging a different crime violates this provision." Id. at 768, 767, 614 P.2d 224.
¶ 15 In Carr, this court extended the holding in Lutman to the pretrial amendment of an information, reaffirming Olds in the process. 97 Wash.2d at 440, 645 P.2d 1098. In Carr , the defendant was originally charged with failing to register to carry goods intrastate. Id. at 438, 645 P.2d 1098. Prior to trial, the prosecution discovered that the goods in question were to be transported interstate, to Utah, not intrastate. Id. Just before trial began, the prosecutor amended the information to charge the defendant under a different statute, which required that he register to carry goods interstate. Id. The trial court granted Carr a one-week continuance to prepare for the new charge, as well as an additional continuance at the conclusion of the State's case. Id. Carr was found guilty of the amended charge. Id. We held that despite the difference in the timing of the amendments made in Carr and in Lutman , the concerns in Carr were "analogous to the Lutman case." Id. at 440, 645 P.2d 1098. We noted that in Lutman, amending the complaint to a new charge "[a]t the conclusion of the evidence" violated Lutman's rights to be informed of the accusations against him. Id. There was no substantive difference in Carr , as we held that "amending the complaint at the start of trial violated Carr's right to be informed of the accusations against him." Id.
B. Pelkey and its progeny
¶ 16 Five years after we decided Carr , the court accepted review of Pelkey . 109 Wash.2d at 488, 745 P.2d 854. The State originally charged Pelkey with one count of bribery. Id. at 486, 745 P.2d 854. However, "[a]t the conclusion of the presentation of the State's case at trial," the State amended the information to charge trading in special influence, a different crime. Id. We held that allowing the amendment violated Pelkey's article I, section 22 rights. Id. at 491, 745 P.2d 854.
¶ 17 The State argued that under CrR 2.1, the defendant bears the burden of establishing that prejudice resulted from the midtrial amendment. Id. at 490, 745 P.2d 854. We rejected this argument, repeating that CrR 2.1 operates "within the confines of article I, section 22" and that "[w]e cannot sustain an interpretation of a court rule which contravenes the state constitution." Id. Accordingly, we reversed Pelkey's conviction. Id. at 491, 745 P.2d 854.
¶ 18 In doing so, we created a rule that
[a] criminal charge may not be amended after the State has rested its case in chief unless the amendment is to a lesser degree of the same charge or a lesser included offense. Anything else is a violation of the defendant's article 1, section 22 right to demand the nature and cause of the accusation against him or her.
*528Id. A violation of this right is per se prejudicial for the purposes of CrR 2.1.
¶ 19 The bright-line rule established in Pelkey , which prohibits certain midtrial amendments, is not concerned with whether the State has formally rested. As Justice Utter repeatedly stated in the Pelkey decision, a trial court cannot allow the "State to amend the information ... after the State completed presentation of its case in chief." Id. at 487, 745 P.2d 854 (emphasis added); see also id. at 485, 745 P.2d 854 (other instances of this language). In State v. Markle, we reaffirmed this, stating that "amending a criminal charge after the State had presented its case in chief violate[s] the defendant's state constitutional rights under article 1, section 22 to be informed of the charges against him when the new charge is not a lesser included offense or an offense of a lesser degree." 118 Wash.2d 424, 433, 823 P.2d 1101 (1992) (emphasis added). Indeed, in Markle we did not even evaluate whether the State had formally rested-that the amendment was made at the end of the State's case in chief (described as a "midtrial amendment") was enough to disqualify it as "reversible error per se." Id. at 437, 823 P.2d 1101.
¶ 20 On the other hand, we have declined to apply Pelkey's bright-line rule when the State amends its case in the midst of its case in chief, when the defendant has an opportunity to respond meaningfully to the amendment. Schaffer, 120 Wash.2d at 620-21, 845 P.2d 281. In Schaffer, the trial court initially denied the State's motion to amend for lack of evidence of the charge sought. Id. at 618, 845 P.2d 281. In response, the State called an additional witness to testify. Id. After the witness's testimony, the State renewed its motion, and the trial court granted the amendment. Id. The defense then had the opportunity to cross-examine the witness (which it did), after which the State rested. Id. Schaffer was found guilty of the amended charge. Id. We upheld the amendment, noting that the rule established in Pelkey did not extend to this situation. Id. at 620-21, 845 P.2d 281. The court will grant relief in these circumstances only if the defendant was prejudiced by the amendment. CrR 2.1(d). In so doing, Schaffer reaffirmed the Pelkey rule, noting that the State cannot amend its information "following the close of the State's case." Id. at 621, 845 P.2d 281.
II. The amendment to the information violated Gehrke's constitutional rights to receive notice of the nature of the charges and an opportunity to present a defense
¶ 21 Here, the State moved to amend the information immediately before resting its case. The State told the court, upon moving to amend, that it "intend[ed to] rest[ ] [regardless] of the Court's decision [to allow the amendment]." Gehrke argues that the Pelkey rule applies to this situation. We agree. By informing the court that it would rest its case regardless of the court's decision of the amendment, the State made clear that it had completed its case in chief. As Pelkey and Markle stated expressly, when the State has completed its case in chief, it cannot amend the information. Pelkey, 109 Wash.2d at 487, 745 P.2d 854 ; Markle, 118 Wash.2d at 433, 823 P.2d 1101. In light of that, we agree with Gehrke. The Pelkey rule applies, and the amendment is barred as per se prejudicial.4
¶ 22 Situations like the one before us now are within the scope of the Pelkey rule because when the State explicitly states that *529it will rest its case after moving to amend, it has functionally rested its case in chief. Pelkey , Markle , and Schaffer reiterate that the Pelkey rule applies when the State has completed its case in chief. If these statements are to mean something, they must mean, at least, that when the State has made it clear that it will rest its case, then it may no longer amend. We hold, therefore, that in a situation like the one before us here, where the State made it clear that it has completed its case in chief, the Pelkey rule applies.
¶ 23 The dissent argues, and the concurrence agrees, that Gehrke's case cannot be within the scope of the Pelkey rule because the Pelkey rule requires that the State formally rest its case; without such ritual formalism, the dissent indicates, the Pelkey rule cannot apply. Dissent at 534; concurrence at 533.
¶ 24 But this is wrong. Pelkey never required the talismanic invocation of the phrase, "the State rests." Only once does the Pelkey opinion state that its bright-line rule applies when the State "has rested its case." Pelkey, 109 Wash.2d at 491, 745 P.2d 854. In every other instance, Justice Utter makes clear that the Pelkey rule applies once the State has completed its case in chief. Id. at 485-86, 745 P.2d 854.5 In the face of this, it does not matter whether the State has "formally rested" its case. Rather, Pelkey was, and remains, concerned with whether the State had completed its case in chief.6 When the State informs the trial court that after its motion to amend, it will rest its case, then it has completed its case in chief. That is what the State did here. Accordingly, the Pelkey rule applies.
¶ 25 This is not to say that formalities are irrelevant. The formality of Miranda7 warnings, for instance, are central to criminal procedure. But the rule advocated for by the dissent and the concurrence would make formal resting the only indicator of whether the Pelkey rule applies and would elevate formality over reality in a manner that undermines Pelkey. Such a formalistic rule ignores the underlying logic of that case. Pelkey held that article I, section 22 assures that a defendant will not be faced with a situation where the State can amend its case without affording the defendant an opportunity to adequately respond. See Schaffer, 120 Wash.2d at 620, 845 P.2d 281 (citing Leach, 113 Wash.2d at 695-96, 782 P.2d 552 ). Were the State allowed to amend prior to resting but when it has made clear that it has completed its case in chief (as was the case here), the Pelkey rule would be rendered toothless. From the defendant's perspective - the perspective *530the Pelkey rule is concerned about - there is no difference between allowing an amendment immediately before the State rests and immediately after, in a situation where, as here, the State has made clear it will rest regardless of whether the court allows the amendment. Any "unsettl[ing]" of the Pelkey rule is perpetrated by the dissent and the concurrence, not by our opinion. See dissent at 534; concurrence at 533. Pelkey therefore applies.
¶ 26 Applying Pelkey in the instant case creates no "unnecessary confusion" for litigants, trial judges, or appellate courts. Dissent at 534; see also concurrence at 533. Pelkey's bright-line rule remains intact. Litigants and judges both are given a clear statement of the law: when the State has made it abundantly clear that it will rest its case after moving to amend, irrespective of the decision on that amendment, then the State has completed its case in chief and the Pelkey rule applies. No substantial "factual finding" is required of appellate courts to understand when this has occurred. See dissent at 534. Here, all that was required was to look at what the State actually said : that it would rest its case after moving to amend, irrespective of whether that amendment was permitted. A trial court and an appellate court need only take a prosecutor at his or her word to resolve this question.
¶ 27 We do not move the line of where the Pelkey rule applies any further into the State's case in chief than did Pelkey or Schaffer. The facts here, indeed, are very specific, concerning a likely rare situation in which the State has said it will rest after amending. Schaffer 's holding that the Pelkey rule does not apply in the midst of the State's case in chief thus stands. If the State had not completed its case in chief-and, for instance, had made clear that were the amendment denied, it would then call witnesses whose testimony would be used to support the amendment, as the State did in Schaffer -the outcome of this case would be different. That would not fall within the Pelkey rule. But that is not what happened. The State made it clear that it had completed its case in chief. In such a situation, the Pelkey rule applies.
¶ 28 Contrary to the State's arguments, the amended charge in this case more closely resembles the amendments made in Pelkey and Markle than that made in Schaffer. As in Pelkey and Markle, the State here did not move to amend until it had finished presenting its entire case in chief. Gehrke was not given an opportunity during the State's case to defend against the amended charge of manslaughter, which contains an element not present in felony murder: recklessly causing the death of another. He had not been charged with manslaughter during voir dire, and he was unable to cross-examine any witnesses called by the State with the objective of raising a reasonable doubt as to recklessness in the death of Pineyro. All the concerns that this court had in Pelkey and reaffirmed in Markle exist with equal force here.
¶ 29 This case is unlike Schaffer, in which the trial court initially denied the State's motion, forcing the State to present additional testimony to support the amended charge. 120 Wash.2d at 618, 845 P.2d 281. In Schaffer, following the new witness testimony, the State renewed its motion and it was granted. Id. Importantly, "Schaffer had the opportunity to cross-examine the key witness ... with full knowledge of the proposed amendment" after the amendment was allowed. Id. at 622, 845 P.2d 281. Here, the amendment came after the State had presented all its witnesses, and Gehrke was not able to cross-examine any witnesses regarding the new manslaughter charge.
¶ 30 Schaffer indeed demonstrates why we must answer as we do today. There, we noted that when protecting defendants' rights to fair notice of the charges and the opportunity to present a defense, "this court has avoided technical rules. Instead, we have tailored our jurisprudence toward the precise evil that article I, section 22 was designed to prevent-charging documents which prejudice the defendant's ability to mount an adequate defense by failing to provide sufficient notice." Schaffer, 120 Wash.2d at 620, 845 P.2d 281 (citing Leach, 113 Wash.2d at 695-96, 782 P.2d 552 ).
¶ 31 The State also argues that the State's informing Gehrke of the possibility of a later amendment prior to voir dire provided *531adequate notice. Suppl. Br. of Resp't at 12. We disagree. Warning a defendant that the State "may" charge an additional offense after the State presents its evidence does not provide the "reasonable certainty" necessary to satisfy the defendant's constitutional right to be properly informed of the charges. See Leach, 113 Wash.2d at 695, 782 P.2d 552 ("[D]efendants have a right to be fully informed of the nature of accusations against them so that they may prepare an adequate defense. This right is satisfied when defendants are apprised with reasonable certainty of the accusations against them." (citations omitted) ); see also City of Seattle v. Proctor, 183 Wash. 299, 304, 48 P.2d 241 (1935) ("[A defendant] is entitled to have the nature of the accusation against him sufficiently stated for the further reason that he may be enabled to prepare his defense."). Nor does a pretrial oral alert "fully inform[ ]" the defendant of the nature of the accusations such that the defendant should be expected to mount a defense against the hypothetical charge. Leach, 113 Wash.2d at 695, 782 P.2d 552. The State's implication that defendants must form a defense around the possibility of additional charges is entirely antithetical to our constitutional guaranties under article I, section 22.
¶ 32 Were it considered adequate notice to advise the defendant that another charge "may" be added, the defendant would be uniquely harmed. The defendant, once told that the prosecution might add another charge, would have the option either to proceed as if that charge will never be brought or to alter the defense to address that possibility. This creates a dilemma. If the defendant chooses to act as if the charge will never be brought but the prosecution does bring the additional charge at the close of the State's case, then the defendant will have insufficiently prepared to defend against it. However, if the defendant expends time and resources defending against the charge and the prosecution declines to bring it, then the defendant will have wasted that time and those resources, which would otherwise have solely been utilized defending against the actual charge brought. Given that what to charge (and not to charge) rests solely in the hands of the State-and that in any criminal case the power of the State vastly outweighs that of the criminal defendant-the State cannot avoid the rules established by Pelkey and its progeny merely by dropping pretrial hints regarding possible additional or amended charges. To permit the State to wait until resting its case to amend the information would allow fundamental unfairness to creep into the trial, and "our system of the administration of justice suffers when any accused is treated unfairly." Brady v. Maryland, 373 U.S. 83, 87, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963). The State must put all of its cards on the table at the outset; the State may not bluff.
¶ 33 Not only is a verbal hint insufficient to notify a defendant of the charges but, here, the prosecutor did not even give Gehrke an accurate warning against which he could have mounted a defense. In telling Gehrke that the State "may" add a charge, the prosecutor also mistakenly indicated that first degree manslaughter was a lesser offense to felony murder. If manslaughter were a lesser included offense, it would by its nature require no additional notice and no changes to the defense at trial, as a lesser included offense necessarily contains only elements present in the charged offense. State v. Berlin, 133 Wash.2d 541, 545, 947 P.2d 700 (1997). However, the prosecutor's warning to Gehrke was misleading: first degree manslaughter is not a lesser included offense to Gehrke's original felony murder charge. State v. Gamble, 154 Wash.2d 457, 469, 114 P.3d 646 (2005) ("We hold that first degree manslaughter is not a lesser included offense of second degree felony murder where second degree assault ... is the predicate felony."). Second degree felony murder based on second degree assault requires the State to prove that the defendant "acted intentionally and 'disregard[ed] a substantial risk that [substantial bodily harm] may occur,' " while first degree manslaughter requires the State to prove that the defendant " '[knew] of and disregard[ed] a substantial risk that a [homicide] may occur.' " Id. at 467-68, 114 P.3d 646 (alterations in original) (emphasis omitted) (quoting RCW 9A.08.010(1)(c) ). Further, "[b]ecause manslaughter requires the proof of a mens *532rea element [recklessness] vis-à-vis the resulting death, while felony murder as charged here [predicated on second degree assault] does not, it cannot be a lesser included offense to the State's felony murder charge." Id. at 469, 114 P.3d 646. Therefore, the prosecutor's warning did not alert Gehrke to such additional elements or the crucial differences between the two crimes. Thus the State cannot convincingly argue that the erroneous "warning" provided Gehrke with constitutionally sufficient notice to mount a defense against the then hypothetical charge.
¶ 34 The State also argues that Gehrke's failure to request a continuance is evidence that the amendment should be upheld. This, too, is inapposite. Failure to seek a continuance indicates a lack of surprise and prejudice only when the amendment is made at the beginning of trial. See State v. Brown, 74 Wash.2d 799, 801, 447 P.2d 82 (1968) (holding that failure to request a continuance after an information is amended at the start of trial is "persuasive of a lack of surprise and prejudice"). When the State amends the charges after it has presented its entire case in chief, as it did here, a continuance is of little value: a jury has been picked, opening arguments have been made, and the defense has already cross-examined the State's witnesses-all based on the offense as charged. See Pelkey, 109 Wash.2d at 490, 745 P.2d 854 ("All of the pretrial motions, voir dire of the jury, opening argument, questioning and cross examination of witnesses are based on the precise nature of the charge alleged in the information."). Furthermore, Gehrke's attorney indicated that he would have sought a continuance had the information been amended prior to the commencement of trial.
¶ 35 Finally, the State's amendment also does not fit into either of the two exceptions to the rule against midtrial amendments. These exceptions apply when the amendment either is to a lesser degree of the original charge or is a lesser included offense of the original charge. Pelkey, 109 Wash.2d at 491, 745 P.2d 854. Here, the State initially charged Gehrke with second degree felony murder predicated on second degree assault and then moved to amend to first degree manslaughter. As we held in Gamble, "first degree manslaughter is not a lesser included offense of second degree felony murder where second degree assault ... is the predicate felony." 154 Wash.2d at 469, 114 P.3d 646 ; see also Berlin, 133 Wash.2d at 550, 947 P.2d 700. Thus, the first degree manslaughter charge could not have been a lesser included offense. See id. First degree manslaughter is also not a lesser degree felony murder. Therefore, neither of the exceptions to the rule applies.8
¶ 36 In light of this, we hold that by allowing this amendment to the information, the trial court abused its discretion as it acted on an erroneous view of the law set down in Pelkey . State v. Quismundo, 164 Wash.2d 499, 504, 192 P.3d 342 (2008) ("a court 'would necessarily abuse its discretion if it based its ruling on an erroneous view of the law' " (quoting Wash. State Physicians Ins. Exch. & Ass'n v. Fisons Corp., 122 Wash.2d 299, 339, 858 P.2d 1054 (1993) ) ).
III. We remand to the trial court for vacation of Gehrke's conviction and dismissal of the first degree manslaughter charge with prejudice
¶ 37 Gehrke has asked us to order that his manslaughter conviction be dismissed *533with prejudice pursuant to the mandatory joinder rule. The mandatory joinder rule provides that related charges against a defendant shall be consolidated for trial. CrR 4.3.1(a). Charges are related within the meaning of this rule if "they are within the jurisdiction and venue of the same court and are based on the same conduct." CrR 4.3.1(b)(1). In the case of an untimely amendment to the information, the mandatory joinder rule requires dismissal with prejudice of the charge in the late-filed amendment (unless the ends of justice exception applies). See State v. Dallas, 126 Wash.2d 324, 327-28, 892 P.2d 1082 (1995) (citing Pelkey, 109 Wash.2d at 491, 745 P.2d 854 ).
¶ 38 In light of this clear precedent, we agree with Gehrke. We remand to the trial court for vacation of his conviction and dismissal of the first degree manslaughter charge with prejudice.9
CONCLUSION
¶ 39 For the foregoing reasons, we reverse the Court of Appeals and remand to the trial court for vacation of Gehrke's conviction and dismissal of the first degree manslaughter charge with prejudice, and for further proceedings consistent with this opinion.
