Section 5 Power of court in action for specific performance.

Where an action is instituted for the specific performance of a contract relating to registered land, the court before which the action is pending may cause all or any parties who have registrable rights in the land, or have entered cautions or inhibitions against the same, to appear in the action and show cause why the contract should not be specifically performed, and the order of the court in the action shall be binding on those parties or any of them.
