QUESTION $2$

$[20$ Marks$]$

A written agreement was concluded by Mr A and $MrB$ for the building of a wall. In addition, a Shifren clause was added $($any

amendment of the contract must be in writing and signed by the parties$).$ The party requesting the wall $($Mr A$)$ then asked

that the height of the wall be increased for an additional fee. The request was in the form of an email with a normal

signature of the requestor. Mr B replied and agreed to change the size of the wall. Examine and discuss whether the

amendment is valid given the existence of the Shifren clause.
