A federal appeals court on Friday ruled that potentially hundreds of defendants charged for their actions at the Jan. 6, 2021, Capitol riot had their sentences improperly lengthened, raising the possibility that many will have to be resentenced.

The U.S. Court of Appeals for the District of Columbia Circuit ruled that Jan. 6 defendants who obstructed Congress‘s efforts to certify the 2020 election had their sentences improperly lengthened by federal judges who determined they had interfered with the “administration of justice.”
