The Board of Appeals may render its decision in summary format, setting forth the Board’s decision and conditions imposed, if any, without enumerating detailed findings which formed the basis for its determination. Any person aggrieved by a decision of the Board of Appeals may, within 30 days after filing of the summary decision in the office of the City Clerk, file a written demand with the City Clerk, demanding that the Board of Appeals adopt and file a long form decision. The City Clerk shall deliver this demand to the Chairman of the Board of Appeals, who shall cause the Board of Appeals to adopt and file a long form decision with the City Clerk. Such long form decision shall fully set forth the circumstances of the case, shall contain a full record of the findings on which the decision is based, and, if such decision is not in accordance with any recommendation of the Planning Board, shall state the reasons therefor. If any aggrieved person seeks judicial review without having requested a long form decision, the Chairman or a member of the Board of Appeals may submit the Board's findings by affidavit as part of the Board's court pleadings. The Board may also adopt a long form decision to include with its papers in opposition to the petition.
