The Reed Smith Shipping Group recently published a client alert that looks at the effectiveness of what are commonly termed “no variation” or “anti-oral variation” clauses (i.e. clauses which purport to prevent the contract in question from being amended absent compliance with specified requirements). They are commonly found in commercial contracts in numerous guises. Normally they specify that to be effective, any amendment to the contract must be in writing and signed by the contracting parties. In the alert, we specifically look at the recent MWB Business Exchange Centres Ltd. v. Rock Advertising Ltd.  EWCA Civ 553 decision under English law.
