A federal judge temporarily blocked a Los Angeles law requiring businesses seeking city contracts to disclose any links to the National Rifle Association (NRA).

The Los Angeles City Council passed an ordinance in February requiring companies doing business with the city to disclose any financial connections to the gun-rights advocacy organization.

The NRA responded with a federal lawsuit against the city, arguing the policy silences NRA members and supporters in the city by forcing them to disclose their ties with the organization.

U.S. District Judge Stephen V. Wilson granted a preliminary injunction prohibiting enforcement of the ordinance while the case moves forward.

However, the judge granted the city’s motion to dismiss claims the ordinance violates the NRA’s equal protection rights under the Fourteenth Amendment and the ordinance has the effect of compelling speech.

Also, the judge removed Mayor Eric Garcetti and the city clerk as defendants in the lawsuit.

The city may appeal the ruling or the NRA may request the injunction be made permanent.
