Guidelines for Lobbyists

Adherence to these rules and guidelines in the everyday conduct of legislative matters enhances the legislative process.  Failure to observe them  inhibits the interchange of information and discredits the legislative process and those who participate therein.

Lobbyists should familiarize themselves with Article XXIX of the Colorado Constitution, Colorado Revised Statutes 24-6-301 through 24-6-309, and any rules of the General Assembly concerning lobbying (Joint Senate and House Rule 36; Senate Rules 31 and 41; House Rules 39, 40 and 41).

Professional lobbyists wear a blue identification badge that differentiates them from legislative staff.

The following are summarizations and the relevant statutes should be reviewed if specific questions arise.

  • The drafting, introduction, sponsorship, consideration, debate, amendment, passage, defeat, approval, or veto by any covered official on any bill, resolution, amendment, nomination, appointment or report, or any other matter pending or proposed for consideration by either the General Assembly or a committee thereof, whether or not the General Assembly is in session;
