Examination of evidence by Town Board.

When in a contested case a majority of the members of the Town Board who are to render the final decision have not heard the case or read the record, the decision, if adverse to a party to the proceeding other than the Sewer District itself, shall not be made until a proposal for decision is served upon the parties and an opportunity is afforded to each party adversely affected to file exceptions and present briefs and oral argument to the members who are to render the decision.
