Headline: Court allows Montana law to bar juries from considering voluntary intoxication when deciding a defendant’s mental state, making it harder for intoxicated defendants to use drunkenness to negate criminal intent.

Supports prosecutorial proof of intent where intoxication evidence is excluded.

Summary

Background

A man camping and drinking in Montana was found in the back of a car after two people in the front seat were shot dead. His blood-alcohol level was very high and a gun with discharged casings was near the brake pedal. He was tried for two counts of deliberate homicide, an offense that under Montana law requires proof that the defendant acted "purposely" or "knowingly." Montana law §45-2-203 told the jury not to consider voluntary intoxication when deciding whether the defendant had the required mental state.

Reasoning

The Montana Supreme Court had ruled that excluding intoxication evidence violated the defendant’s right to present a defense and to have the jury consider evidence on every element. The U.S. Supreme Court, in the judgment announced by Justice Scalia, reversed. The majority said the Due Process Clause does not guarantee an absolute right to introduce all relevant evidence, pointed to a long common-law tradition rejecting intoxication as an excuse, and accepted state choices about defining mental-state rules or excluding such evidence for policy reasons. Justice Ginsburg concurred, viewing the statute more as a legislative redefinition of mens rea. Several Justices dissented, arguing the exclusion undermined a defendant’s fair opportunity to challenge proof of intent.

Real world impact

The ruling permits Montana’s approach and supports similar statutes in other States that bar use of voluntary-intoxication evidence to negate intent. Defenders must adjust strategies where such exclusions exist, while prosecutors may face fewer obstacles proving intent. The decision leaves room for States to define crimes and evidence rules differently.

Dissents or concurrances

Dissenting Justices argued the blanket exclusion unacceptably weakened a defendant’s ability to raise reasonable doubt about an essential element of the crime.
