Morrison v. Jacobs (1945) 1 KB 577

Scott, L.J., said: "The sole question before the court is whether after the expiration of the contractual tenancy the mere fact of the landlord receiving rent for the dwelling house from the tenant affords any evidence that the landlord had entered on a new contractual tenancy to take the place of the tenancy which had expired. In my opinion, it does not. The true view is that the landlord takes the rent, knowing that the tenant is granted a statutory tenancy by the Rent Restrictions Acts and that his right to gain possession of his dwelling house depends entirely on his establishing that he brings himself within the conditions laid down by the Acts."
