Ashburn Anstalt v Arnold

 is an English land law case decided by the Court of Appeal. It establishes that in English law rent is not required for the creation of a tenancy. However its judgement on the requirements on certainty of duration of a lease has been discredited by "Prudential Assurance Co v London Residuary Body" 2 AC 386
Facts.
Arnold & Co had a lease of some business premises at 126 Gloucester Road, Kensington, London. It sold the lease to Matlodge Ltd subject to a promise the old lessee could remain for free in occupation as ‘licensees’ until any redevelopment on a quarter's notice in writing, and that on redevelopment that they should get a lease of a shop in a prime position at the development with 1000 square metres and car parking. Then Cavendish Land Co Ltd acquired both the freehold and the lease, accepting the contractual duties to Arnold & Co. Then Cavendish was taken over by Legal & General Assurance Society Ltd, which accepted the contract. Then L&G sold its freehold to Ashburn Anstalt, which also took the freehold ‘subject to’ the Arnold & Co contract. It had no redevelopment plans but sought possession anyway.
Arnold & Co argued that its interest bound Ashburn Anstalt, as: 1. it was a lease, and thus an overriding interest under LRA 1925 section 70; 2. if it was just a licence, it should bind anyway, under "Errington v Errington" or be a constructive trust.
Evans-Lombe QC sitting as judge in the High Court held the agreement created only a licence but that licence bound Ashburn Anstalt, and possession was refused.
Judgment.
Fox LJ held that Arnold & Co were considered to be occupying on a lease which bound the new landlord. Rent was not necessary to create a tenancy, the occupation agreement was certain enough, and it was thus an overriding interest, as they were in actual occupation, even though it was not registered as an estate contract, applying "Street v Mountford". If they had only had a contractual licence, Arnold & Co could not have asserted its right against Ashburn Anstalt. Any suggestion in "Errington v Wood" that a licence creates an interest in land was wrong, according to "Thomas v Sorrell". A mere contractual licence could not bind as a constructive trust without there being an express promise. It was uncertain whether a rent was necessary for having a tenancy, relying on "Street v Mountford", however "Radaich" was held to be the authoritative definition, and that did not include any mention of a rent. There would only be a constructive trust, continued Fox LJ, if,
Neill LJ and Bingham LJ concurred.
