Since private act charters and home rule charters are different, a great deal of careful reading is necessary to determine purchasing rules for each type of municipality. If the charter does not mention purchasing and competitive bidding, buying for the municipality is governed by the 1983 Municipal Purchasing Law.
Generally, if the charter has provisions governing competitive bidding and purchasing, the municipality is governed by the charter. However, due to the vagueness of some charter provisions, it may be difficult to know if a municipality is exempt from the 1983 Municipal Purchasing Law. Each municipality must make a decision about this.
