COKER v. TAYLOR WOODROW (Civil Case No. 290/66))  SLSC 1211 (05 February 1967);

Landlord and Tenant -fixtures-removal-fixtures affixed by tenant not generally severable without landlord's consent
If one party to a contract by his conduct leads another party to believe that the strict rights arising under the contract will not be insisted upon, intending that the other should act on that belief, and he does act on it, then the first party will not afterwards be allowed to insist on the strict rights when it would be inequitable for him to do so, and he will be taken to have waived performance of the relevant condition of the contract (page 42, lines 21-24, 27-33).
