Publication of the Colorado Revised Statutes occurs several months following the end of each regular legislative session. Prior to such publication, the Office of Legislative Legal Services prepares the Digest of Bills and concurrent resolutions as required under section 2-3-504, C.R.S. The Digest consists of summaries of all bills and concurrent resolutions enacted by the Sixty-seventh General Assembly at its First Regular Session ending May 6, 2009. The summaries include the dates bills are approved and the effective dates of the bills. The Digest is not a substitute for the text of the bills or for provisions of Colorado Revised Statutes, but gives the user notice of and summary information on recent changes to the statutes.
