Rehearing and review of prior decisions. Upon motion initiated by any member and adopted by the unanimous vote of the members present, the Development Board shall review, at a rehearing held upon notice given as upon an original hearing, any order, requirement, decision, interpretation, or determination of the Development Board not previously reviewed. Upon such rehearing, and provided it shall then appear that the rights vested prior thereto in persons acting in good faith in reliance upon the order, requirement, decision, interpretation, or determination reviewed will not be prejudiced thereby, the Development Board may, upon the concurring vote of all the members then present, reverse, modify, or annul its original order, requirement, decision, interpretation, or determination.
