A sold his business to B on the condition that B help maintain his widow,
C, once A had died. B reneged on the promise and C sued him.
HL held that 3rd party beneficiaries of a contract cannot sue on it, due to privity of contract. However C was able to sue for specific performance of the duty as the executrix of A’s will.
HL said specific performance should be used if it would provide a “more perfect justice”
