ACCORDING to Section 56, an agreement to do an act impossible in itself is void (for example, an agreement to discover treasure by magic). Supervening impossibility or illegality refers to the intrusion or occurrence of an unexpected event or change of circumstances beyond the contemplation of the parties; such event or change of circumstances must be so fundamental as to be regarded by law as striking at the root of contract as a whole or the basis of the contract no longer exists.
