Substitute amendment

An amendment that completely replaces language in a bill with different language. Substitute amendments can be offered in subcommittee, committee, or on the floor. If accepted, the substitute "kills" the replaced text. A form of substitute amendment occurs when a motion is made to "strike all after the enacting clause" of a bill passed by the other Chamber "and insert in lieu thereof" the text of its own, already-approved legislation. The result of this is two versions of a bill under one bill number,and is the first step toward a conference to resolve the differences between the two versions.
