Neither the Mayor nor any Councilmember shall vote or participate in discussion or deliberation on any question in which he or she has a substantial personal or financial interest, direct or indirect, including an interest held through a spouse or family member, other than the common public interest, or on any question concerning his or her own conduct. In the event the Mayor or any Councilmember has such an interest, he or she shall declare such interest. Whether or not such a declaration is made, the remaining Councilmembers may determine by a majority vote whether said interest does in fact constitute a conflict of interest. When such conflict of interest is established, the Mayor or Councilmember affected shall not vote on the matter, and the remaining Councilmembers shall take any further action they deem to be in the best interests of the Town. If such conflict of interest was not disclosed and is established with respect to a matter already considered by the Town Council, the remaining members of the Town Council shall take any action they deem to be in the best interests of the Town, including, but not limited to, terminating the unperformed portion of any contract entered into when such a conflict of interest existed. This Section and any ordinance adopted in furtherance thereof shall abrogate and replace any common law doctrine on this subject. (Amended January 17, 2019)
