Legislative History Overview

A legislative history is a record of sources documenting a bill’s passage into law. The most important legislative history source documents are:

  • Committee reports
  • Floor debate
  • Original and amended bills, and
  • Committee hearings

A legislative history can take many forms, including the following:

  • A collection of the full source documents
  • A list of source documents
  • A narrative of a bill’s passage into law
  • A law as originally passed with all amendments made by subsequent Congresses

Why research legislative history? Researching legislative history is sometimes used to interpret the meaning of statutory text, though such a practice is criticized by some. Legislative history can also help you understand the purpose and function of a statute, i.e., what it was intended to do and how it was intended to do it. Students and new associates will often be tasked with the job of compiling a legislative history. So knowing about legislative history will let you hit the ground running.
