19.—Where the Court, on an application for a new tenancy under this Part finds that the tenant is not entitled to a new tenancy—

(a) if the notice of intention to claim relief includes a claim in the alternative for compensation, the Court shall hear and determine the claim and fix the amount of any compensation;

(b) if the notice of intention to claim relief does not include a claim in the alternative for compensation, the Court may, on the application of the tenant, if having regard to all the circumstances of the case the Court thinks proper to do so, amend the notice in such terms as the Court thinks proper by inserting in it a claim in the alternative for compensation and thereupon deal with that claim in accordance with paragraph (a).
