The position at common law is that frustration discharges the parties only from duties of future performance. Rights accrued before the frustrating event therefore remain enforceable but those which have not yet accrued do not arise. This may cause hardship, as exemplified in Chandler v Webster. Here money for hire of a room for the King's coronation was due in advance. Not all the monies had been paid when the coronation was postponed, but the hirer was still liable to pay the full amount. The payment had fallen due before the frustrating event.
