In Keeling v. City of Grand Junction, 689 P.2d 679 (Colo. App. 1984), the Court held that city employees did not have a vested contractual right in the continuance of a particular rate or method of compensation. This decision was based, in large part, on the principle that a legislative body cannot enter into a contract that will bind succeeding bodies and thereby deprive them of the unrestricted exercise of their legislative power.
