WASHINGTON — The Supreme Court on Tuesday declined to hear a Second Amendment challenge to a California law that imposes a 10-day waiting period on firearms purchases.

As is their custom, the justices gave no reasons for deciding not to hear the case. The court has turned away many Second Amendment cases in recent years, to the frustration of gun-rights groups and some conservative justices.

Justice Clarence Thomas filed an impassioned 14-page dissent in the case, Silvester v. Becerra, No. 17-342. “As evidenced by our continued inaction in this area,” he wrote, “the Second Amendment is a disfavored right in this court.”

In 2008, in District of Columbia v. Heller, the Supreme Court ruled that the Second Amendment protects an individual right to keep guns at home for self-defense.
