The following rules shall govern the conduct of city officers in their dealing with the city:
(A) Anti-nepotism. Unless the Council shall by 5/7 vote, which shall be recorded as part of its official proceedings, determine that the best interests of the city shall be served and the party considered by such a vote has met the requirements for appointive office or employment specified in this Charter, the following relatives of any elective or appointive officer are disqualified from holding any appointive office or employment during the term for which said elective or appointive officer was elected or appointed; spouse, child, parent, grandchild, grandparent, brother, sister, half-brother, half-sister, or the spouse of any of them. All relationships shall include those arising from adoption. This section shall in no way disqualify such relatives or their spouses who are bona fide appointive officers or employees of the city at the time of the election or appointment of said official.
(B) General conflict of interest. Members of the Council or of any board or commission of the city, or any city administrative official or employee, shall refrain from voting or otherwise participating in any issue or matter, including any contract with the city or the sale of any land, material, supplies and services to the city, in which he or a member of his family, or a corporation in which he or a member of his family is a stockholder, shall have a proprietary or financial interest, direct or indirect, or as the result of which he or a member of his family may receive or gain a financial benefit, direct or indirect. In addition, such interest or possible benefit shall be made known in timely fashion by the city official or employee involved. Willful concealment of such a proprietary or financial interest or possible benefit, or violation of other requirements of this section, shall constitute malfeasance in office or position and constitute grounds for forfeiture of such office or position. Violation of this section with the knowledge expressed or implied of the person or corporation contracting with or making a sale to the city shall render such contract or sale voidable by the City Council or City Manager.
