The Constitution derives its authority from the Student body of the Institute of Technology Sligo. The only way to make amendment to the constitution is through a referendum. A referendum may be called on any issue by: (1) A Union General Meeting. (2) A SRC Meeting. (3) 10% of the Student Body. (4) The Union Executive Committee. All referenda are to be decided by a three-fifths majority. A quorum of 10% of the Union membership is required to validate a referendum. All motions must be posted on the main Union notice boards at least 5 college days before the referendum for constitutional amendments. The original text and the proposed amendment must be posted on main Union notice boards 5 days in advance also.

The Union and its officers shall, at all times, act within the General Law and its Constitution. The constitution is downloadable here.
