In Under Appeal of Booz, 111 Pa. Commw. 330, 533 A.2d 1096 (Pa. Cmwlth. 1987), the applicant applied to the board for a variance to permit the expansion of its tractor repair service to include sales and leasing of new tractors and trailers. Applicant also sought to erect two signs advertising its dealership. At the hearing, opponents appeared and presented testimony in opposition to the variance. The board thereafter granted a variance for erection of the signs. As to the actual expansion of the business, the board granted a special exception instead of a variance. In determining that a remand was appropriate this court stated: Where, as here, the application of an alternate legal theory is first undertaken by the Board at the time of the deliberation, the Board must likewise provide notice and an opportunity to be heard to any objectors who entered an appearance at the first hearing. Such notice may be accompanied either by individual written notice to the objectors or by public notice of a second hearing specifying the legal theory which the Board has determined to be applicable. Since Appellees in the instant case were not afforded notice and an opportunity to satisfy their burden in opposition to the grant of a special exception to Appellants, we find it necessary to remand for further proceedings. Id. at 1099.
