Section 6612 - Appeal from Board's decision(a) Any person or persons, jointly or severally affected by any decision or nondecision of the Board, or any taxpayer, or any officer, department, board or bureau of the State, may appeal to the Superior Court in and for the county in which the use in question is wholly or principally located by filing a petition, duly verified, setting forth that such decision is illegal, in whole or in part, specifying the grounds of the illegality. Any such appeal shall be perfected within 30 days of the decision of the Board. (b) The Court may affirm, reverse or modify the Board's decision. The Board's findings of fact shall not be set aside unless the Court determines that the record contains no substantial evidence that would reasonably support the findings. If the Court finds that additional evidence should be taken, the Court may remand the cause to the Board for completion of the record.7 Del. C. 1953, § 6612; 59 Del. Laws, c. 213, § 1.;
