On any application under section 140 or 141 or to bring land under this Act, the Registrar may grant the application although the certificate to be issued or the rectification of the register to be made upon that application may affect land comprised in any other certificate of title if it appears that the land so affected has been included in such other certificate of title by reason of some error in survey or other misdescription unless the title to the land so affected has been theretofore determined in a contested proceeding under this Act or in any court of competent jurisdiction in which the right to the possession of that land was in question.
