# Blackledge v. Allison

## Holding or rule used

Strong plea-declaration presumption without an invariably insurmountable bar to specific collateral allegations.

## Material limitation

Use only for the bounded proposition in the linked § 2255 module. State-habeas holdings are not silently converted into direct § 2255 holdings; record, circuit, local, deadline, custody, waiver, and classification issues remain separate where identified.
