No act or omission in connection with any registration in the Mineral and Petroleum Titles Registration Office shall be invalidated by any formal defect, whether such defect occurs in any deed passed or registered or in any document upon the authority of which any such deed has been passed or registered or which is required to be produced in connection with the passing or registration of such deed, unless a substantial injustice has by such act or omission been done, which in the opinion of the court cannot be remedied by any order of court.
