Bruton v London and Quadrant Housing Trust [1999] UKHL 26 is an English land law case that examined the rights of a 'tenant' in a situation where the 'landlord', a charitable housing association had no authority to grant a tenancy, but in which the 'tenant' sought to enforce the duty to repair on the association implied under landlord and tenant statutes. The effect of the case is to create the relationship of de facto landlord and tenant between the parties.
