30(3)Where in the opinion of the Registrar General a caveat forwarded to him pursuant to subsection (2) has been improperly registered in that the interest claimed thereunder is not an interest in land or should be registered in the form of an instrument that creates an interest or passes an estate in the land, he shall make an order directing the registrar, after the expiration of such time as the Registrar General shall specify in the order, unless an appeal is taken within that time, to withdraw the caveat from registration.
