A resolution, rule, or order of a joint board dealing with a subject authorized by Section 22.014 or 22.081 is effective only on approval of the governing authorities of the constituent agencies. On approval, a resolution, rule, or order of the joint board has the same effect in the territories or jurisdictions involved as an ordinance, resolution, rule, or order of the public agency would have in its own territory or jurisdiction.
