The Constitution of the International Brotherhood of Boilermakers is the primary governing document of the union. It governs the actions of the International and local lodges, as well as those of all officers, staff, and members at all levels of the union. When necessary, the International president interprets the Constitution, but its language can be changed only by a vote of delegates at a Consolidated Convention.
