OPINION

Justice TODD.

In this appeal by the Commonwealth, we accepted review to consider whether Appellee John Brock waived his speedy trial claim under Pa.R.Crim.P. 600, either by failing to file a written motion to dismiss, or by failing to appear for a trial listing. We hold that Rule 600 requires a defendant to file a written motion to dismiss, and that, by failing to appear in court on the day his or her case is listed for trial, a defendant waives his or her Rule 600 claim. Accordingly, we reverse.

On June 3, 2003, the Commonwealth filed a criminal complaint against Brock, charging him with burglary, attempted murder, aggravated assault, criminal trespass, and firearms violations. Brock was arrested on June 16, 2003. The case was first listed for trial on December 15, 2003, but was continued numerous times until March 8, 2005. On that date, Brock, who was on house arrest pursuant to Pa. R.Crim.P. 600(E),1 failed to appear for court. A bench warrant for his arrest was issued on March 18, 2005; however, when police went to his residence on that date, he was not there. Thereafter, the Commonwealth made no further efforts to locate him.

On January 25, 2006, Brock was arrested in Williamsport, Pennsylvania on unrelated charges. On that same day, a Williamsport police officer notified authorities in Philadelphia that Brock was in custody, but no attempt was made to secure his return to Philadelphia for trial. On September 27, 2006, authorities from the State Correctional Institute at Camp Hill ("SCI-Camp Hill") notified Philadelphia police that Brock was in custody on an unrelated matter. At this point, the Commonwealth arranged for Brock's return to Philadelphia to stand trial on the June 3, 2003 charges.

On May 24, 2007, Brock's attorney orally argued that he was entitled to the dismissal of all charges, with prejudice, pursuant to Pa.R.Crim.P. 6002 because more than 365 days of non-excludable time had elapsed from the date of the filing of the original criminal complaint. That same day, the trial court held a hearing on Brock's oral motion. Eight months later, the trial court held a second hearing on January 18, 2008, at which the Commonwealth argued that Brock waived his Rule 600 claim by failing to file a written motion. Additionally, the Commonwealth asserted that Brock waived his Rule 600 claim by failing to appear for the trial listing on March 8, 2005. On January 18, 2008, the trial court granted Brock's motion and dismissed the charges against him.

In granting Brock's motion to dismiss, the trial court concluded, inter alia, the Commonwealth failed to exercise due diligence between January 25, 2006 (the day it was notified that Williamsport police had Brock in custody) and September 27, 2006 (the day it was notified that Brock was in custody at SCI-Camp Hill) because it made no attempt to have Brock returned to Philadelphia for trial. Thus, the trial court found this 244-day period chargeable to the Commonwealth, and held that, at the time Brock moved for discharge, there already had been 504 days of non-excludable time and the run date for Rule 600 had expired. The trial court further rejected the Commonwealth's contention that Brock waived his Rule 600 claim by failing to file a written motion. Citing Commonwealth v. Bowes, 839 A.2d 422 (Pa.Super.2003), the trial court stated "Rule 600 contains no requirement that a motion to dismiss be written." Trial Court Opinion, 3/19/08, at 5. The Commonwealth appealed.

On June 8, 2010, the Superior Court affirmed the trial court's decision in an unpublished memorandum opinion. The Superior Court first rejected the Commonwealth's argument that Brock waived his Rule 600 claim by failing to file a written motion. Like the trial court, the Superior Court relied on its decision in Bowes for the proposition that an oral motion is sufficient to preserve a Rule 600 claim. The court further rejected the Commonwealth's argument that Brock waived his Rule 600 claim by failing to appear in court on March 8, 2005, the date his case was listed for trial. The court reasoned that a trial commences under Rule 600 when the first substantial step toward the guilt-determining process occurs, and, because there was no evidence that such first step occurred on March 8, 2005, trial had not commenced, and thus Brock had not waived his Rule 600 claim. Commonwealth v. Brock, 435 EDA 2008, unpublished memorandum at 7, 4 A.3d 678 (Pa.Super. filed June 8, 2010).

Thereafter, the Commonwealth filed a petition for allowance of appeal, which this Court granted to address the following question: "Did the trial court err in dismissing the serious charges against defendant under Rule 600, where he waived his Rule 600 claim by failing to file a motion to dismiss, and by voluntarily failing to appear for the March 8, 2005 trial listing?" Our standard of review in evaluating a Rule 600 claim is whether the trial court abused its discretion. Commonwealth v. Selenski, 606 Pa. 51, 58, 994 A.2d 1083, 1087 (2010). We begin by addressing the Commonwealth's argument that Brock waived his Rule 600 claim by failing to file a written motion to dismiss.

Rule 600, titled "Prompt Trial," provides, in relevant part:

Pa.R.Crim.P. 600.

The Commonwealth contends the Superior Court's holding below — that an oral motion to dismiss was sufficient — conflicts with this Court's decision in Commonwealth v. Drake, 489 Pa. 541, 414 A.2d 1023 (1980). In Drake, the defendant made an oral motion for dismissal pursuant to former Pa.R.Crim.P. 1100, now Rule 600.3 The trial court denied the motion on the merits. On appeal, the Superior Court affirmed, but concluded the defendant had waived his Rule 1100 claim by failing to file a written application to dismiss. Upon further appeal, this Court affirmed the Superior Court's decision, explaining that Rule 1100(g)4:

Id. at 544, 414 A.2d at 1024-25 (footnote omitted).5

In response to the Commonwealth's argument, Brock first suggests that, "[e]ven assuming that as a general rule motions to dismiss under Rule 600 should be in writing," the trial court in this case did not abuse its discretion by granting his oral motion to dismiss in this case because: (1) the Commonwealth "readily responded" to the oral motion by participating in a review of the docket and calculation of the run date without objection; (2) the Commonwealth was granted a continuance to conduct an investigation for purposes of rebutting evidence introduced by Brock in support of his motion; and (3) the Commonwealth "expressed a mere pro forma objection to the absence of a written motion" after it presented evidence at the second hearing. Appellee's Brief at 10.

Additionally, with respect to this Court's decision in Drake, Brock contends this Court should not "regard its 1980 decision pertaining to Rule 1100 as automatically applicable to Rule 600. After all, the legislature knows how to legislate a requirement that a pretrial motion be written." Id. at 11.6 As an example, Brock points to Pennsylvania's Rape Shield Statute, which provides, in part, that a "defendant who proposes to offer evidence of the alleged victim's past sexual conduct pursuant to subsection (a) shall file a written motion and offer of proof at the time of trial." 18 Pa.C.S.A. § 3104(b).

Brock further suggests that Drake should not apply because:

Appellee's Brief at 11.

Upon review, we conclude the Superior Court erred in determining Drake was not controlling, and in holding that an oral motion to dismiss is sufficient to preserve a Rule 600 claim. In attempting to distinguish this Court's decision in Drake, the Superior Court below reasoned:

Brock, 435 EDA 2008, at 5.

Although the language of Rule 1100, now Rule 600, has been amended several times, under both versions of the rule, the relevant language is substantially the same, and a defendant is required to serve a copy of the motion to dismiss upon the attorney for the Commonwealth. Former Rule 1100(g) provided:

Pa.R.Crim.P 1100(g). As noted supra, Rule 600(G) currently provides, in relevant part:

Pa.R.Crim.P. 600(G). Additionally, the comment to Rule 600 expressly provides, "A copy of the motion must be served on the attorney for the Commonwealth, who has a right under this rule to be heard on the motion." Pa.R.Crim.P. 600 cmt.

Thus, contrary to the Superior Court's suggestion, Rule 1100 was never "abolished," and the pertinent language of former Rule 1100 and Rule 600, including that a defendant "may apply to the court" and that a "copy of such motion shall be served upon the attorney for the Commonwealth," remains the same.

Critically, as we explained in Drake, the requirement that a copy of a motion to dismiss "be served upon the attorney for the Commonwealth" clearly presupposes the filing of a written motion. Drake, 489 Pa. at 544, 414 A.2d at 1024; see also Commonwealth v. Martin, 479 Pa. 609, 613 n. 3, 388 A.2d 1361, 1364 n. 3 (1978) (Rule 1100(g) clearly contemplates a written requirement in light of the mandate that a copy be served upon the attorney for the Commonwealth). Drake remains good law, and the Superior Court erred in ignoring the plain language of Rule 600 and Drake's mandate. Thus, we reiterate that a motion to dismiss pursuant to Pa. R.Crim.P. 600 must be made in writing, and a copy of such motion must be served on the Commonwealth's attorney. To the extent Bowes holds otherwise, it is hereby disapproved.

Nevertheless, Brock alternatively argues that we should not find he waived his Rule 600 claim by failing to file a written motion under the circumstances of this particular case. Specifically, Brock notes that the prosecutor did not object to proceeding with a review of the docket pursuant to his oral motion, and made only a pro forma objection to the lack of a written motion nearly eight months later at a second hearing on the issue. Appellee's Brief at 11. We need not address this contention, however, as we find Brock waived his Rule 600 claim on a distinct basis.

As noted above, the Commonwealth also contends Brock waived his Rule 600 claim by failing to appear in court on the date his case was listed for trial, despite having been notified that he must appear on that date. In support of its contention, the Commonwealth relies on this Court's decision in Commonwealth v. Steltz, 522 Pa. 233, 560 A.2d 1390 (1989), wherein we held that a defendant's voluntary absence from a scheduled trial date resulted in waiver of his rule-based right to a speedy trial. Specifically, the defendant in Steltz appeared for the call of the trial list on the morning of the day trial was scheduled to begin, which fell within the Rule 1100 run date. The jury venire was empanelled and jury selection was scheduled to begin at 3:00 p.m. that same day, but when the defendant failed to appear at that time, the trial judge ordered a recess until the next morning. The defendant again failed to appear, and was apprehended eleven days later. Trial was rescheduled for a date outside the Rule 1100 date, and, on that day, the defendant filed a pre-trial motion to dismiss pursuant to Rule 1100. The trial court granted the motion, and the Superior Court affirmed. Upon appeal by the Commonwealth, this Court reversed, stating:

Id. at 235, 560 A.2d at 1391 (emphasis added).

The Superior Court in the instant case distinguished Steltz on the basis that the defendant therein absconded only after the first step toward the guilt-determining process had occurred — namely, the jury venire had been empanelled. The Superior Court noted Rule 600 provides that, where a defendant is at liberty on bail, trial must commence no later than 365 days from the date on which the complaint is filed, and reasoned that, for purposes of determining when a trial has commenced,

Commonwealth v. Brock, 435 EDA 2008, at 6 (quoting Commonwealth v. Fooks, 345 Pa.Super. 145, 497 A.2d 1346, 1348 (1985)). The Superior Court concluded that, because the trial court did not direct the parties to proceed to "any stage which leads directly into the guilt determining process," trial had not "commenced" in the instant case, and, therefore, Brock did not waive his Rule 600 claim. For the following reasons, we reject the Superior Court's attempt to distinguish Steltz.

Subsection (B) of Rule 600 provides "[f]or the purpose of this rule, trial shall be deemed to commence on the date the trial judge calls the case to trial, or the defendant tenders a plea of guilty or nolo contendere." Pa.R.Crim.P. 600(B). The comment to Rule 600 provides, inter alia:

Pa.R.Crim.P. 600 cmt.

Former Chief Justice Eagen discussed the meaning of the comment to Rule 600 in Commonwealth v. Lamonna:

473 Pa. 248, 260, 373 A.2d 1355, 1361 (1977) (Eagen, C.J., concurring)

Rule 600 was designed to prevent unnecessary prosecutorial delay in bringing a defendant to trial. For purposes of calculating whether a defendant is brought to trial within the time constraints of Rule 600, requiring that commencement of trial be marked by a substantive, rather than a pro forma, event prevents the Commonwealth from manipulating the Rule 600 clock by initiating superficial or non-substantive court proceedings. Requiring that the commencement of trial be marked by a substantive event places an obligation on the Commonwealth to ensure that the spirit behind Rule 600 is not compromised.

However, when a defendant deliberately fails to appear in court on the day his case is listed for trial, these concerns simply are not implicated. As we explained in Steltz, a trial date for one defendant is a delay for another, and the failure of a defendant to appear at any proceeding to which he was summoned impacts not only the trial judge, attorneys, and jurors, but also other defendants who are awaiting trial. The impact of the defendant's failure to appear is equally adverse regardless of the stage of the proceedings; once a case has been is listed for trial, it is irrelevant whether the defendant absents himself before the proceedings commence or after a substantive event had occurred, as in Steltz. A defendant cannot be permitted to frustrate the judicial process in this manner.

Accordingly, as in Steltz, we hold that Brock, in voluntarily failing to appear for his scheduled trial listing, waived his Rule 600 claim. Thus, his trial shall be at the reasonable convenience of the trial court.7 Steltz, 522 Pa. at 235, 560 A.2d at 1391.

For the reasons set forth above, we reverse the decision of the Superior Court, and remand this matter for further proceedings.

Justice ORIE MELVIN did not participate in the decision of this case.

Justice SAYLOR, EAKIN, BAER and McCAFFERY join the opinion.

Chief Justice CASTILLE files a concurring opinion.

Chief Justice CASTILLE, concurring.

I join the Majority Opinion, subject to a point of clarification respecting footnote 7, which states that the Majority does not mean to suggest that appellee has waived any potential claim based upon a constitutional right to a speedy trial. Maj. Op. at 1022. I also write to supplement the Majority's discussion on the waiver arising from appellee's failure to appear.

First, and pertinent to footnote 7, appellee may well have, in fact, waived any claim involving his constitutional right to a speedy trial. However, if the intention of footnote 7 is merely to convey the Majority's belief that appellee's failure to appear at his trial did not result in automatic waiver of his constitutional speedy trial right, I concur. But, that is not to suggest that there was any meritorious constitutional argument to be forwarded here; the point is that a failure to appear defeats the Rule-based right.

Second, as the Majority has noted, in Commonwealth v. Steltz, 522 Pa. 233, 560 A.2d 1390 (1989), this Court held that a defendant's voluntary absence from a scheduled trial date results in waiver of his Rule-based speedy trial rights, and Steltz remains good law. As the Majority notes, the panel's attempted distinction of Steltz is unpersuasive; moreover, it is not the proper function of the lower courts to seek to narrow the plain import of this Court's unambiguous legal holdings. It should be remembered that trial notices and subpoenas are not social invitations, to be declined or ignored at the whim of the defendant. Any contrary approach, at least in the context of Rule 600, would be absurd. To reward a defendant's failure to appear by invocation of Rule 600 can only act to encourage similar gaming by a defendant, and others in the future. Because of the extreme nature of the Rule 600 remedy — discharge — waiver appropriately should follow.1
