An association can be described as an organized body of individuals who have some interest, activity, or purpose in common. The role of an association in the legislative process is very important. One way to illustrate how important an association is to the legislative process is to show the effect it has on a certain piece of legislation. The vehicle used to show this importance is House Enrolled Act 1104, a bill passed by the 1992 Indiana General Assembly on mine subsidence. The paper is divided into four distinct sections. The first section introduces mine subsidence, describes the federal legislation, describes the state legislation, and informs the reader off the need for new legislation concerning mine subsidence. The second section introduces the major players and explains who they are, what they wanted from the legislation, and what they contributed to the legislation. The third section follows House Enrolled Act 1104 through the legislative process. The last section summarizes the changes to the mine subsidence statute and describes some observations of the author.
