Jones v London Borough of Merton [2008] EWCA Civ 660, [2008] All ER (D) 185 (Jun)
The liability of a tolerated trespasser to pay mesne profits to a former landlord terminates when the tolerated trespasser decides to give up possession and removes his belongings from the dwelling house, not at the time when the former landlords are formally notified that he is no longer in possession of the dwelling. This is so even though the tolerated trespasser continued to retain the keys to the dwelling.
