What is a meeting of all members of the Senate or the House called?

A meeting of all members of the Senate or the House is referred to as a Joint Session. This term specifically denotes a gathering where both chambers of the state legislature come together to conduct business, often for significant events such as a governor's address or to consider particular legislation. In a Joint Session, all legislators participate collectively, promoting collaboration and communication between the two bodies.

The other terms, while related to legislative processes, define different aspects or events. A Special Session is called to address specific legislative matters outside the regular session schedule, while a Constitutional Convention involves assembling delegates to discuss and propose changes to the state constitution. The General Assembly refers to the collective legislative body, which encompasses both the Senate and the House but does not specifically indicate a gathering of all members. Therefore, the term Joint Session accurately captures the essence of the assembly of all legislators from both houses.
