71.25(14)(b) (b) Before the department of revenue grants permission to any corporation to use an alternative method of allocation under par.

(a), the department of revenue shall submit the proposed alternative method of apportionment to the cochairpersons of the joint committee for review of administrative rules, together with a description of the proposed alternative and the reasons for the proposed alternative. If, within 14 days after receipt of the proposed alternative method, the cochairpersons of the joint committee for review of administrative rules do not notify the department of revenue that the proposed alternative must be promulgated as an administrative rule in order to be used, the department of revenue may give final approval to the proposed method without promulgating an administrative rule. If the cochairpersons of the joint committee for review of administrative rules notify the department of revenue within 14 days after receipt of the proposed alternative that the proposed alternative must be promulgated as an administrative rule, the proposed alternative may not be used until it is promulgated as an administrative rule under ch. 227.
