Landlord and tenant – Covenant against assignment without consent. A landlord of a block of flats was not entitled, without breach of covenant, to grant a licence to a lessee to carry out work which would breach an absolute covenant contained in a lease of her flat where the leases of other flats required him to enforce covenants at the request of a lessee of one of those other flats. The Court of Appeal, Civil Division, accordingly granted a declaration to that effect.
