(a) Representation by a former city council member or former board or commission member. A person who was a member of the city council, a board or commission, or another city body shall not represent any person, group, or entity (other than himself or herself or his or her relative) for a period of one year after the termination of his or her official duties:
(1) before the city council or that board, commission, or body;
(2) unless the board, commission, or body of which the former city official or employee was a member is only advisory in nature:
(A) before city staff having responsibility for making recommendations to, or taking any action on behalf of, the city council or that board, commission, or body; or
(B) before a board, commission, or other city body that has appellate jurisdiction over the board, commission, or body of which the former city official or employee was a member, if any issue relates to his or her former duties.
(b) Representation before the city. A former city official or employee shall not represent for compensation any person, group, or entity (other than himself or herself or his or her relative) before the city for a period of one year after termination of his or her official duties. This subsection does not apply to a person who was classified as a city official only because he or she was an appointed member of a board, commission, or other city body. For purposes of this subsection, "compensation" means money or any other thing of value that is received, or is to be received, in return for or in connection with such representation.
(c) Representation in litigation adverse to the city. A former city official or employee shall not, for a duration of one year after completing his or her service with the city, represent any person, group, or entity (other than himself or herself or his or her relative) in any litigation to which the city is a party, if the interests of that person, group, or entity are adverse to the interests of the city and the matter is one in which the former city official or employee personally participated prior to termination of his or her official duties or is a matter substantially related to such a matter.
