Morris v Baron and Co: HL 1918

The House drew a distinction between a variation of a contract required to be evidenced in writing, and the rescission (or discharge) of such a contract. The former was itself required to be evidenced in writing; the latter was not.
Lord Dunedin said: ‘The criterion is in the question whether what is intended to be effected by the second contract is rescission or variation.’
Lord Parmoor said that the determining factor on which the appeal depended was the intention of the parties at the time when the second agreement was made.
Whether a variation amends the principal agreement or discharges and replaces it depends on the intention of the parties. To establish a discharge and replacement, ‘there should have been made manifest the intention in any event of a complete extinction of the first and formal contract, and not merely the desire of an alteration, however sweeping, in terms which are still subsisting’
