Landlord and tenant – Breach of covenant to repair. The Court of Appeal, Civil Division, allowed the defendant tenant's appeal on two issues arising out of proceedings brought by the claimant landlord for alleged breach of repairing covenants contained in the lease of business premises. Among other things, it held that the tenant's replacement of the tiled carpeting system with a strip carpet system shortly before the determination of the lease had constituted a permitted alteration and the tenant had not been in breach of covenant in relation to the carpets.
