delivered the opinion of the Court.
This сase presents the question whether defense counsel’s agreement to a trial date outside the time period required by Article III of the Interstate Agreement on Detainers bars the defendant from seeking dismissal because trial did not occur within that period.
I
The Interstate Agreement on Detainers (IAD) is a compact entered into by 48 States, the United States, and the District of Columbia to establish procedures for resolution of one State’s outstanding charges against a prisoner of another State. See N. Y. Crim. Proc. Lаw § 580.20 (McKinney 1995); 18 U. S. C. App. § 2; 11A U. L. A. 48 (1995) (listing jurisdictions). As “a eongressionally sanctioned interstate compact” within the Compact Clause of the United States Constitution, Art. I, § 10, cl. 8, the IAD is a federal law subject to federal construction.
Carchman
v.
Nash,
*112
A State seeking to bring charges against a prisoner in anоther State’s custody begins the process by filing a detainer, which is a request by the State’s criminal justice agency that the institution in which the prisoner is housed hold the prisoner for the agency or notify the agency when release is imminent.
Fex
v.
Michigan,
In this case, New York lodged a detainer against respondent, who was a prisoner in Ohio. Respondent signed a request for disposition of the detainer pursuant to Article III of the IAD, and was returned to New York to face murder and robbery charges. Defense counsel filed several motions, which, it is uncontested, tolled the time limits during their pendency.
On January 9, 1995, the prosecutor and defense counsel appearеd in court to set a trial date. The following colloquy ensued:
“[Prosecutor]: Your Honor, [the regular attorney] from our office is engaged in a trial today. He told me that *113 the Court was to set a trial date today. I believe the Court may have preliminarily discussed a May 1st date, and [the regular attorney] says that would fit in his calendar.
“The Court: How is that with the defense counsel?
“[Defense Counsel]: That will be fine, Your Honor.”164 Misc. 2d 1032 , 1035, 627 N. Y. S. 2d 234, 236 (Cty. Ct., Monroe County 1995).
The court scheduled trial to begin on May 1.
On April 17, 1995, respondent moved to dismiss the indictment, arguing that the LAD’s time limit had expired. The trial court found that as of January 9, 1995, when the trial date was set, 167 nonexcludable days had elapsed, so that if the subsequent time period was chargeable to the State, the 180-day time period had indeed expired. However, the trial court concluded that “[d]efense counsel’s explicit agreement to the trial date set beyond the 180 day statutory period constituted a waiver or abandonment of defendant’s rights under the IAD.” Id., at 1036, 627 N. Y. S. 2d, at 237. Accordingly, the court denied respondent’s motion to dismiss.
Respondent was subsequently convicted, following a jury trial, of murder in the second degree and robbery in the first degree. On appeal, respondent аrgued that the trial court erred in declining to dismiss the indictment for lack of a timely trial under the IAD. The New York Supreme Court, Appellate Division, affirmed the decision of the trial court. 244 App. Div. 2d 927, 668 N. Y. S. 2d 126 (1997). The New York Court of Appeals, however, reversed and ordered that the indictment against respondent be dismissed; defense counsel’s agreement to a later trial date, it held, did not waive respondent’s speedy trial rights under the IAD. 92 N. Y. 2d 406,
*114 II
No provision of the IAD prescribes the effect of a defendant’s assent to delay on the applicаble time limits. We have, however, “in the context of a broad array of constitutional and statutory provisions,” articulated a general rule that presumes the availability of waiver,
United States
v.
Mezzanatto,
What suffices for waiver depends on the nature of the right at issue. “[Wjhether thе defendant must participate personally in the waiver; whether certain procedures are required for waiver; and whether the defendant’s choice must be particularly informed or voluntary, all depend on the right at stake.”
United States
v.
Olano,
Scheduling matters are plainly among those for which agreement by counsel generally controls. This case does not involve a purported prospective waiver of all protection of the IAD’s time limits or of the IAD generally, but merely agreement to a specified delay in trial. When that subject is under consideration, only counsel is in a position to assess the benefit or detriment of the delay to the defendant’s case. Likewise, only counsel is in a position to assess whether the defense would even be prepared to proceed any earlier. Requiring express assent from the defendant himself for such routine and often repetitive scheduling determinations would consume time to no aрparent purpose. The text of the IAD, moreover, confirms what the reason of the matter suggests: In allowing the court to grant “good-cause continuances” when either “prisoner or his counsel” is present, it contemplates that scheduling questions may be left to counsel. Art. 111(a) (emphasis added).
Respondent offers two arguments for affirmance, both of which go primarily to the propriety of allowing waiver of
*116
any sort, not to the specifics of the waiver here. First, he argues that by explicitly providing for the grant of “good-cause continuances,” the IAD seeks to limit the situations in which delay is permitted, and that permitting other extensions of the time period would override those limitations. It is of course true that waiver is not appropriate when it is inconsistent with the provision creating the right sought to be secured.
E. g., Crosby
v.
United States,
Second, respondent argues that the IAD benefits not only the defendant but society generally, and that the defendant may not waive society’s rights. It is true that a “right conferred on a private party, but affecting the public interest, may not be waived or released
if such waiver or releasе contravenes the statutory policy” Brooklyn Savings Bank
v.
O'Neil,
Society may well enjoy some benefit from the IAD’s time limits: Delay can lead to a less accurate outсome as witnesses become unavailable and memories fade. See,
e. g., Sibron
v.
New York,
Finally, respondent argues that even if waiver of the IAD’s time limits is possible, it can be effected only by affirmative conduct not present here. The New York Court of Appeals adopted a similar view, stating thаt the speedy trial rights guaranteed by the IAD may be waived either “explicitly or by an affirmative request for treatment that is contrary to or inconsistent with those speedy trial rights.” 92 N. Y. 2d, at 411,
* * *
The judgment of the New York Court of Appeals is reversed.
It is so ordered.
Notes
It was suggested at oral argument that agreement in open court to a trial date outside the allowable time period can itself be viewed as a “necessary or reasonable continuanсe” for “good cause shown in open court.” Although an agreed-upon trial date might sometimes merit this description, it is far from clear that it always does so, or that it does so here. Because we find waiver, we do not consider under what circumstances an аgreed-upon delay could fit within the good-cause provision.
This feature, among others, makes respondent’s analogy to the federal Speedy Trial Act of 1974, 18 U. S. C. §3161
et seq.,
inapt. The time limits of the Speedy Trial Act begin to run automatically rather than upon request, §§ 3161(a), (b); dismissаl may sometimes be without prejudice, §§ 3162(a)(1), (2),
United States
v.
Taylor,
In concluding that objectiоn to a specified delay may be waived, we are mindful that the sending State may have interests distinct from those of the prisoner and the receiving State. This case does not involve any objection from the sending State, and we do not address what recourse thе sending State might have under the IAD when the receiving State and prisoner agree to, and the court allows, an inordinate delay. Cf. Article V(e) (“At the earliest practicable time consonant with the purposes of this agreement, the prisoner shall be returned to the sending State”).
