Any of the rules can be changed with each new Congress, but in practice each new session amends a standing set of rules built up over the history of the body in an early resolution published for public inspection.[54] Before legislation reaches the floor of the House, the Rules Committee normally passes a rule to govern debate on that measure (which then must be passed by the full House before it becomes effective). For instance, the committee determines if amendments to the bill are permitted. An "open rule" permits all germane amendments, but a "closed rule" restricts or even prohibits amendment.
