# Tanner v. United States

## Holding used

Voluntary juror intoxication is not an outside influence under the federal no-impeachment rule, which operates alongside trial safeguards and admissible nonjuror evidence.

## Material limitation

The decision does not erase Rule 606(b)'s textual exceptions or the later constitutional racial-bias exception.

## Official source and pinpoints
