§ 109. Appearances of municipal corporations. Each municipal
corporation shall have the right to appear as a party before the
commission or before any court in any action or proceeding involving

any of its residents. Any city, village, county or town may appropriate
and expend such an amount as the governing body of such municipality may
determine to be necessary for the purpose of paying the expenses of the
employment of expert and technical advisors, engineers, accountants,
appraisers, attorneys, and other persons in connection with any matter
to be presented to the commission in any action or proceeding involving
electric, gas and water rates, service or other matters to which it is a
party.
