the question of compensation will remain whether an order of injunction is or is not passed. It cannot surely be urged that in a suit for specific performance the plaintiff is entitled to ask, during the pendency of litigation, that the defendant in whom the legal title still vests should be restrained from using the property. If the plaintiff were so entitled, then in a suit for specific performance the defendant would be required to vacate the property which he had contracted to sell or lease. That surely cannot be the law."
