OPINION OF THE COURT
In this рrosecution for burglary and related charges, the issue is whether a defendant who pleaded guilty forfeited the right to contend that the fact-finding process of the Grand Jury, culminating in an indictment against him, was impaired by the prosеcutor’s introduction of inadmissible hearsay.
During the Grand Jury presentation, the complainant, Harold Stickney, testified that shortly after midnight his wife awoke him after hearing noises outside their home, and called 911; that he saw defendant on their back porch holding a snow shovel; that he watched as defendant unsuccessfully tried to open the sliding glass door to the house, then kicked it in; and that, after pointing an antique gun at defendant, the two struggled and the police arrived. Washington County Deputy *229 Sheriff Scott Stark testified that, at the scené, he saw Stickney on the ground, and also heard someone running from the house in the snow, whereupon he and his partners chased and apprehendеd defendant. According to Stark, defendant stated he was on the Stickney property to shovel snow.
Defendant testified on his own behalf before the Grand Jury, admitting a history of alcohol and drug abuse. He claimed that on the night of the incident, he was “all strung out” on prescription medication, felt “extremely paranoid” and wanted to get some fresh air to cool down. Defendant acknowledged going onto the Stickney property, first to the garage and then to the porch, where he picked up a blue shovel that, in the light over the garage, prompted him to hallucinate. Then he saw Harold Stickney holding a gun.
Following this testimony, the prosecutor played а portion of a videotaped television newscast containing first a reporter’s lead-in and then an interview with defendant. The reporter’s full remarks, about a minute in length, noted that elderly homeowners had thwarted an intrudеr in an attempted break-in, and that defendant was charged with the crime. The prosecutor played two portions of these remarks — the record does not reveal which portions were actually shown to the grаnd jurors — before fast-forwarding to defendant’s interview. In the interview, defendant claimed to have been on the Stickney property to help them shovel snow.
After playing the videotape, the prosecutor advised thе grand jurors that “the only thing we are offering this for, ladies and gentlemen, is the statement made by — that’s the basic statement, the statement that he gave.” The prosecutor then cross-examined defendant about his conflicting statеments. At the conclusion of the proceedings, the prosecutor instructed the grand jurors that “only that portion of the tape where [defendant] is making a statement should be considered by you as evidence. The rest of it should be stricken from your deliberations in this case.” Defendant was indicted on charges of first degree burglary, attempted second degree burglary, second degree assault and first degree reckless endangerment.
Defendant sought dismissal of the indictment on the ground that the Grand Jury proceeding was defective because the videotaped remarks amounted to unsworn hearsay that prejudiced him (CPL 210.20, 210.35). The motion court found that the prosecutor had played the reporter’s remarks inadvertently, and denied the application, concluding both that the *230 prosecutor submitted the tape for the purpose of showing defendant’s contradictory statemеnt and that the reporter’s remarks were, in substance, also testified to under oath by the witnesses in the Grand Jury. Defendant thereafter pleaded guilty to one count of attempted first degree burglary and the Appellate Division affirmed, concluding that defendant’s plea amounted to a “waiver” of the contention that the videotape was improperly admitted before the Grand Jury. We now affirm.
Discussion
A plea of guilty, as we have repeatedly observed, generally marks the end of a criminal case, not a gateway to further litigation (Pe
ople v Taylor,
A guilty plea does not, however, extinguish every claim on appeal. The limited issues surviving a guilty plea in the main relаte either to jurisdictional matters (such as an insufficient accusatory instrument) or to rights of a constitutional dimension that go to the very heart of the process (such as the constitutional speedy trial right, the protectiоn against double jeopardy or a defendant’s competency to stand trial)
(see, People ex rel. Battista v Christian,
Defendant contends that his guilty plea did not “waive” his right to seek dismissal of the indictment on the ground that the prosеcutor, by showing portions of the videotaped reporter’s remarks, impaired the integrity of the Grand Jury proceeding. Defendant’s claim, actually a matter of forfeiture, does not activate a question of jurisdictiоn. Before a person may be publicly accused of a felony, and required to defend against such charges, the State must persuade a Grand Jury that sufficient legal reasons exist to believe the person guilty
(People v Iannone,
Additionally, a defendant may not forfeit a claim of a constitutional defect implicating the integrity of the process. Ordinarily, following a defendant’s admission of culpability as to the crime charged, a guilty plea does forfeit a claim “that

the criminal proceedings preliminary to trial were infected with impropriety and error”
(People v Di Raffaele, supra,
at 240). As the United States Supreme Court has explained, a guilty plea “renders irrelevant those constitutional violations not logically inconsistent with the valid establishment of factual guilt and which do not stand in the way of conviction, if factual guilt is validly established”
(Menna v New York,
Defendant in essence seeks a review of the fact-finding process engaged in by the grand jurors with respect to the videotaped remarks. While his cоnstitutional right to be prosecuted on a jurisdictionally valid indictment survived the guilty plea, his right to challenge this evidence did not

By contrast, here, the motion court held that thеre was sufficient evidence before the Grand Jury to support every ele

ment of the crimes charged. Obviously, on a motion to dismiss the indictment, the fact that inadmissible evidence, inadvertently adduced, has been introduced into criminal proceedings does not necessarily alter the validity of the proceedings; rather, such a defect renders the indictment dismissible when the remaining evidence is insufficient to sustain the indictment
(People v Avant,
Defendant relies additionally on our statement that “defects in Grand Jury proceedings (as opposed to claims of insufficiency of evidence to support the indictment, which are barred by CPL 210.30 [6]) may be raised even after a plea of guilty”

Accordingly, the order of the Appellate Division should be affirmed.
Judges Smith, Levine, Ciparick, Wesley and Rosenblatt concur.
Order affirmed.
Notes
. Forfeiture occurs by operation of law as a consequence of the guilty plea, with respect to issues that do not survive the plea. Waiver occurs when a defendant intentionally relinquishes or abandons a known right that would otherwise survive a guilty plea
(see, People v Thomas,
. A defendant may raise, after a guilty plea, certain constitutional claims such as the voluntariness of a plea
(People v Seaberg, supra,
. Claims that are foreclosed by a guilty plea have, for example, included pre-indictment prosecutorial misconduct
