A reading of all the words contained in section 5o(1)(f) of the Act supports the conclusion that the Legislature intended that the term "entertainment facility" constitute a structure or building that has a known seating capacity of 2,500 or more persons, or that has signs above each public entrance stating that the facility has a seating capacity of 2,500 or more persons. Since the Legislature has not required that an entertainment facility be totally self-enclosed, such a facility could consist of a bandshell, amphitheater, or similar structure, provided it has the required, known seating capacity noted above or has appropriate signage above each public entrance indicating a seating capacity of 2,500 or more. This reading of section 5o(1)(f) is supported by the legislative history of 2000 HB 4530, enacted as 2000 PA 231. Both House Legislative Analyses, HB 4530, June 8, 1999, and January 4, 2001, state that HB 4530 would "[p]rohibit a licensee from carrying a concealed weapon in certain public places, such as a school, theater, sports arena, library, or hospital." There is no mention in either bill analysis that an outdoor recreation park, by itself, would constitute a gun-free zone. It is appropriate to rely on the legislative history because of the ambiguity in the statutory language. Luttrell v Dep't of Corr, 421 Mich 93, 103; 365 NW2d 74 (1985).
While the Legislature could certainly have included municipal and other outdoor recreation parks within the Act's list of gun-free zones, it chose not to do so. An entertainment facility having a seating capacity of 2,500 or more persons clearly refers to a building or other structure. Accordingly, if an outdoor recreation park includes a band shell, amphitheater, or similar structure that has the required seating capacity, that portion of the park would constitute a gun-free zone under section 5o(f) of the Act.
