Alvarez v. Smith, 558 U.S. 87 (2009), was a United States Supreme Court decision on seizure of property by the Chicago Police Department, however the case was declared moot by the Court as the parties agreed that there was no longer contention over the property seized.

The Appeals Court overruled its precedent and held that DAFPA did not provide the adequate mechanisms for owners to challenge the seizure of their property.

The Seventh Circuit remanded the case back to the District Court and ordered it to devise a mechanism by which an owner can contest the seizure of his property.

In oral argument the court learned that the parties no longer disputed ownership of the property in question.

Therefore, the majority opinion, written by Justice Breyer, declared the case moot and vacated the judgment of the Seventh Circuit.
