(1) Applicable rules. On application by the organizers of a municipal insurance mutual under s. 611.11 (4), the commissioner may by order, after a hearing, relax any requirements of this chapter to facilitate the formation, financing and governance of the mutual. In the same order, the commissioner shall impose substitute requirements designed to implement the purposes of s. 611.02 (2) as elaborated in this chapter.

(2) Regulation. Except as provided in sub. (3), the provisions of chs. 600 to 646 that apply to other mutuals organized or operating under this chapter apply also to municipal insurance mutuals.
