• noun
1
A trial rendered invalid and terminated before a verdict is reached because of a fundamental procedural error, misconduct, or the inability of the jury to reach a consensus.
Example
"The judge declared a mistrial after the jury remained deadlocked following five days of intense deliberation."
Word Nuance & Usage
A mistrial is not the same as an acquittal; because no valid verdict has been reached, the case is not closed and the prosecution may usually seek a new trial (retrial) without violating the rule against double jeopardy.
