21.—(1) A person who serves a notice of intention to claim relief may, at any time not less than one month thereafter, apply to the Court to determine his right to relief and (as the case may be) to fix the amount of the compensation or the terms of the new tenancy to which he is found to be entitled.

(2) If he does not do so within three months after service of the notice, any person on whom the notice was served may apply to the Court to determine the matters to which the notice relates.

(3) An application under this section may be made, heard and determined either before and in anticipation of or after the termination of the tenancy.
