What it's about

The Armed Career Criminal Act can increase a federal sentence when a person has prior convictions for qualifying drug offenses.

Question presented

Can a conviction under state law be treated as a serious drug offense for purposes of a longer sentence under the federal Armed Career Criminal Act, if the state law violated did not at the time of federal sentencing set a maximum prison term of at least 10 years, but had done so at the time the crime was committed?

What the Court decided

Holding

The District Court properly applied ACCA’s sentencing enhancement to McNeill because all six of his prior drug convictions were for “serious drug offenses.” 598 F. 3d 161, affirmed.

Result
Affirmed

The Court's reasoning

The Court said the sentence increase was proper because all six of McNeill’s prior drug convictions counted as “serious drug offenses.”

The vote

Majority author
Clarence Thomas

What's next

The appeals court’s judgment remains in place, and McNeill’s enhanced federal sentence continues.
