Double Jeopardy Implication

Manifest Necessity Doctrine (United States v. Perez, 22 U.S. 579): When a mistrial is declared over the defendant's objection, the Fifth Amendment guarantee against double jeopardy bars retrial unless the court substantiates a "high degree" of necessity. A genuinely deadlocked hung jury represents the classic manifest necessity, provided the judge conducted adequate inquiry.
Tuey-Rodriguez Instruction (Commonwealth v. Tuey / Commonwealth v. Rodriquez, 364 Mass. 87): Massachusetts rules mandate caution before declaring deadlock. A judge must typically deliver a balanced Tuey-Rodriguez charge urging jurors to reconsider their views without coercing a verdict. In the Lindsay Clancy trial scenario, defense grounds challenge whether this inquiry was prematurely aborted.
Emergency Stay & G.L. c. 211, § 3: The trial court's 60-minute stay permits defense counsel to petition a Single Justice of the Supreme Judicial Court. If the Single Justice stays proceedings, the jury remains impaneled while the appellate court reviews whether manifest necessity legally exists.

|---|---|---|---|
| Genuine Deadlock (Hung Jury) | Manifest Necessity (Court inquiry confirms no reasonable probability of agreement) | Contested or Neutral | Permitted: Jeoaprdy does not terminate; state may retry on original indictment. |
| Premature Mistrial (No Necessity) | Unsubstantiated (Court failed to exhaust deliberative alternatives / Tuey-Rodriguez) | Preserved Objection | BARRED: Double jeopardy attaches; retrial dismissed with prejudice. |
| Prosecutorial / Judicial Bad Faith | Goaded mistrial standard (Oregon v. Kennedy / Com. v. Ellis) | Defense Motion or Objection | BARRED: Retrial prohibited if state deliberately provoked mistrial. |
