Give correct answer and complete explanation.

Ang worked at a Red Robin's in California and believed she was discriminated against by the manager, Pat. Ang then filed a lawsuit against Red Robin's and Pat in the U.S. District Court in California. There was prior precedent from the U.S. Court of Appeals for the Tenth Circuit that dealt with Ang's exact issue. Ang argued that the prior case was binding on the U.S. District Court in California.
