The Supreme Court on Thursday afternoon granted the federal government’s request to be allowed to enforce a federal anti-money-laundering law while the government’s appeal moves forward in the conservative U.

The law requires potentially millions of local businesses to disclose their “beneficial owners,” or anyone with at least a 25% interest or who controls the business, to a federal regulator.

Enforcement of the Corporate Transparency Act, which requires millions of companies to disclose their true ownership, remains on hold despite a U.S. Supreme Court ruling in favor of the Treasury Department.
