"I think it important that this court should not do or say anything which creates the impression that people are liable to be penalised for not enforcing their strict legal rights. It is a very unfortunate state of affairs when people feel obliged to take steps which they do not wish to take, in order to preserve their legal rights, and prevent the other party acquiring rights against them. So the court in using its equitable jurisdiction must, in my judgment, approach these cases with extreme care."
