US v. Leon (1984) established the Good Faith doctrine. What does it say about evidence obtained with a defective warrant?

• A. Good Faith doctrine allows admissibility.
• B. The Exclusionary Rule prohibits all evidence obtained in good faith.
• C. Warrantless searches always valid if cops believe they are lawful.
• D. The Fourth Amendment does not apply to state actions.

Answer: (A)

The main idea tested is how the Good Faith doctrine works after US v. Leon. Leon holds that if police act in objective good faith and rely on a warrant that is later found defective, the evidence seized under that warrant can be admitted in court. In other words, the Exclusionary Rule does not automatically exclude such evidence just because the warrant turns out to be defective. The key point is that the officers’ reliance on the warrant was reasonable and not a product of misconduct or ill intent. There are limits, though: if the warrant is so obviously deficient that no reasonable officer would rely on it, or if the magistrate’s decision was tainted by fraud or a complete abandonment of judicial role, then the evidence may still be excluded. But in the typical defective-warrant scenario, the evidence remains admissible, which is why the correct choice is that the Good Faith doctrine allows admissibility.
