Section 22

Where in any proceedings in court under section 16 for the recovery of possession of any controlled premises or any part thereof or for the ejectment of a tenant or subtenant or joint-tenant therefrom it appears to such court that neither an apportionment of the rent as between the premises and any sublet part thereof nor a determination of the rent of the part so sublet or held by a joint-tenant has previously been made by the Tribunal, the court may, if it thinks fit, refer the matter to the Tribunal for its determination, and the Tribunal shall thereupon proceed as if an application for apportionment had been made under section 21.
