The Supreme Court will alllow North Dakota to enforce its voter ID law.
Opponent of the law said it disenfranchises the Native American population who do not have standard addresses.
The Supreme Court on Tuesday refused to toss out an appeals court order that allows North Dakota to enforce its voter ID requirement during the 2018 elections.
The request to toss out the order came from a group of Native American residents who are challenging a new state law that requires voters to present identification that includes a current residential street address.
The challengers argued the new rule disenfranchises a disproportionate share of the population because many Native American voters live on reservations without standard addresses.
The District Court agreed and temporarily blocked the North Dakota secretary of state from enforcing the new requirements during the primary elections, but the 8th U.S. Circuit Court of Appeals blocked that court order last month.
