Rehearing. A motion for the zoning board of appeals to hold a
rehearing to review any order, decision or determination of the board
not previously reheard may be made by any member of the board. A
unanimous vote of all members of the board then present is required for
such rehearing to occur. Such rehearing is subject to the same notice
provisions as an original hearing. Upon such rehearing the board may
reverse, modify or annul its original order, decision or determination
upon the unanimous vote of all members then present, provided the board
finds that the rights vested in persons acting in good faith in reliance
upon the reheard order, decision or determination will not be prejudiced
thereby.
