U.S. Court of Appeals for the Ninth Circuit

762 F.3d 971 (9th Cir. 2014)

Challenged EPA's decision regarding greenhouse gas emissions from stationary sources under the Clean Air Act. The court applied Chevron deference to the agency's interpretation but remanded for further explanation of the agency's reasoning on the regulatory threshold.

824 F.3d 919 (9th Cir. 2016)

Held en banc that the Second Amendment does not protect a right to carry a concealed weapon in public, upholding San Diego County's restrictive concealed carry permit policy. Later effectively overruled by the Supreme Court's decision in NYSRPA v. Bruen (2022).

847 F.3d 1151 (9th Cir. 2017)

Upheld a temporary restraining order blocking enforcement of President Trump's first travel ban executive order. The court rejected the government's argument that the President's immigration decisions are unreviewable by the judiciary, finding the states had standing and were likely to succeed on due process claims.

189 F.3d 808 (9th Cir. 1999)

Held that a social worker's warrantless entry into a family home and strip search of children, conducted under threat of removal, violated the Fourth Amendment. Established that the government cannot use child welfare investigations to circumvent constitutional protections against unreasonable searches.

786 F.3d 733 (9th Cir. 2015)

Held en banc that an actress's performance in the anti-Islam film 'Innocence of Muslims' did not create an independent copyright interest in her five-second appearance, reversing a prior panel's controversial order requiring YouTube to remove the video. Addressed the intersection of copyright and free speech.
