In Weeks v. United States, the Court establishes the Exclusionary Rule (evidence unconstitutionally obtained must be excluded from trial. The decision states that federal police (or law enforcement) agents violated the plaintiff's Fourth Amendment rights when they entered his house without a warrant, and that therefore the confiscated private documents later used to convict him of illegally operating a lottery through the mail should have been excluded at his trial. The decision overturns Weeks's conviction.
1915
The Court strikes as unconstitutional an Oklahoma "grandfather clause" limiting the right to vote to only those men whose grandfathers had been eligible to vote in 1867 (and therefore excluding all men of African descent). The decision in Guinn v. United States holds that the Oklahoma law is a violation of the Fifteenth Amendment, which extends the right to vote to U.S. citizens of all races.
