37 N.Y.2d 58 (1975)
A defendant, represented by counsel, who pleads guilty to a lesser charge after a trial has begun, waives the right to assert a double jeopardy defense, unless the guilty plea was induced by prosecutorial vindictiveness or other unconstitutional factors affecting the plea itself.
Summary
La Ruffa was initially indicted for first-degree murder, convicted of second-degree murder, and then retried for first-degree murder after his initial conviction was reversed. During the second trial, he pleaded guilty to second-degree murder. He later argued that the second trial for first-degree murder violated his double jeopardy rights. The New York Court of Appeals held that La Ruffa waived his double jeopardy defense by pleading guilty, distinguishing the case from *Blackledge v. Perry* where prosecutorial vindictiveness was a factor. The court reasoned that double jeopardy is a waivable defense and the guilty plea, made with counsel, constituted such a waiver in the absence of vindictiveness or coercion.

Issue(s)
<n
Whether a defendant waives his double jeopardy defense by pleading guilty to a lesser charge after a trial has commenced.
Holding
<n
No, the original decision of affirmance is adhered to. A defendant, with the advice of counsel, waives his double jeopardy defense by pleading guilty to a lesser charge unless the plea was the product of prosecutorial vindictiveness or the plea proceedings were directly affected by antecedent unconstitutionality.
Court’s Reasoning
The court distinguished this case from *Blackledge v. Perry*, emphasizing that *Blackledge* was grounded in due process concerns related to prosecutorial vindictiveness (escalating charges in response to the defendant’s exercise of appeal rights), which was absent in La Ruffa’s case. The court stated that “*Blackledge*, a due process holding, does not change this. While the practical effect of a double jeopardy defense may be to prevent a trial from taking place, it must first be affirmatively raised.” The court relied on *Tollett v. Henderson* and reiterated the principle that a guilty plea, entered knowingly and intelligently with the advice of counsel, generally waives the right to challenge prior constitutional deprivations. The court also emphasized that the plea was entered “in accordance with the then existing constitutional law of double jeopardy.” Absent vindictiveness or some other factor rendering the plea involuntary, the defendant’s plea constituted a waiver of his double jeopardy claim. The court noted that double jeopardy rights are waivable if not timely asserted. The court held that before a guilty plea will not work a waiver, there must be or have been a vindictive or retaliatory escalation of crime charged or sentence for a defendant who pursued his constitutional rights, a circumstance totally absent here.
