could be said to be frustrated if a change in circumstances occurs which is the
fault of neither party and could not be foreseen. If a contract is considered frustrated,
then it is held that the parties have no obligation to one another. In this
instance Mr. Spark might argue that frustration did occur as his wife had gone into
labour, 2 months before
he had anticipated. This is not something Mr. Spark could have foreseen.
Therefore, he might argue that the contract had become frustrated; and so he
was not obligated to do the work set out in the contract.
