根據 contract law
因為typhoon出現
所以係Frustration(履約受挫)
Frustration of a contract occurs when unforeseen events, beyong the parties' control and not provided for in the contract, cause a contracct to become incapable of being performed.
如果出現這情況
any money paid before the frustrating event is recoverable.
any money payable before the frustrating event is no longer payable,
the court has a discretion to allow a party who has incurred expenses before the frustrating event to retain or recover money to cover them , and
where prior to frustration one party has received a valuable benefit, the court may order the payment of a 'just sum' for it.
