(1)An appeal may be brought out of time if on an application for the purpose an inspector or the Board is satisfied that there was a reasonable excuse for not bringing the appeal within the time limited, and that the application was made thereafter without unreasonable delay, and gives consent in writing; and the inspector or the Board, if not satisfied, shall refer the application for determination by the Commissioners.
(2)If there is a right to elect to bring the appeal before the Special Commissioners instead of before the General Commissioners, the Commissioners to whom an application under this section is to be referred shall be the General Commissioners unless the election has been exercised before the application is so referred.
