The Court quickly disposed of Old Chief's first argument, which was that Rule 401 required the district court to exclude the name of the crime of which he had been convicted. Rule 401 defines "relevant" evidence as evidence that makes a fact of consequence more or less probable than without it. Because the fact of a prior felony conviction was an element of the crime of being a felon in possession of a firearm, the Court reasoned that the record of Old Chief's prior conviction was relevant under Rule 401. Hence, if "relevant evidence is inadmissible in the presence of other evidence related to it, its exclusion must rest not on the ground that the other evidence has rendered it "irrelevant," but on its character as unfairly prejudicial, cumulative or the like, its relevance notwithstanding."
