362.6  Conflict of interest.
  A measure voted upon is not invalid by reason of conflict of interest in an officer of a city, unless the vote of the officer was decisive to passage of the measure. If a specific majority or unanimous vote of a municipal body is required by statute, the majority or vote must be computed on the basis of the number of officers not disqualified by reason of conflict of interest. However, a majority of all members is required for a quorum. For the purposes of this section, the statement of an officer that the officer declines to vote by reason of conflict of interest is conclusive and must be entered of record.
