United States Supreme Court - public oral arguments and investitures

The Supreme Court building, opened in 1935, regularly conducts public oral arguments during its term, a formal ritual of the U.S. judicial process that allows advocates to present and answer questions before the justices. The building is also used for ceremonial investitures and formal events when newly appointed justices are publicly introduced. Court proceedings follow long‑standing protocols for attire, oral presentation, and courtroom decorum.
