The governing body of each statutory or home rule charter city, county, school district, regional agency, or other political subdivision, except a town, must have on record a policy that controls travel outside the state of Minnesota for the applicable elected officials of the relevant unit of government. The policy must be approved by a recorded vote and specify:
(1) when travel outside the state is appropriate;
(2) applicable expense limits; and
(3) procedures for approval of the travel.
The policy must be made available for public inspection upon request. Subsequent changes to the policy must be approved by a recorded vote.
