# Arizona v. Washington

## Holding used

Manifest necessity requires a high degree of necessity and sound discretion, while no formulaic phrase or express recital is invariably required if the record shows careful deliberation.

## Material limitation

The degree of deference varies with the basis for mistrial; the complete trial record and alternatives remain essential.
