Where in any proceedings under this Part for the recovery of possession of any premises or any part thereof or for the ejectment of a tenant or sub-tenant therefrom it appears to the 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 sublet part has previously been made by the Board or any court, the court may make such an apportionment or determination, whether or not an order or judgment is given in the proceedings for the recovery of possession or the ejectment of the tenant or sub-tenant.
