“Where the order is still executory, as in the present case, and one of the parties applies to the court to enforce the order, the court may refuse if, in the circumstances prevailing at the time of the applications, it would be inequitable to do so.”
“With respect to cases where there is an undertaking or an order that is still executory the approach to determining whether or not to set aside or vary the order is, as the appellant submits, based upon it being inequitable to hold to the terms of the original order in the light of a significant change of circumstances. Given that this is a case about an executory order, it is not necessary to engage any further with the Appellant's wider submission regarding the test where the jurisdiction may arise in other circumstances.”
“It must be strongly emphasised that in Barder itself, Lord Brandon observed at page 10 that the order under appeal was executory. Yet, fully aware of the decision in Thwaite, the Committee did not decide the case by reference to that doctrine. I agree with Ms Kisser that the Committee must be taken as having impliedly rejected this route as a legitimate source of relief.”
“The first question in deciding whether to exercise the Thwaite jurisdiction is whether there has been a significant (and necessarily relevant) change of circumstances since the order was entered into; and the second question is whether, if there has been such a change, it would be inequitable not to vary the order. For myself, I do not find the words "cautious" and "careful" particularly helpful. There are two requirements to the use of the jurisdiction and their application will ensure that the Thwaite jurisdiction is used with care. There is no additional test or hurdle set out by the Court of Appeal in Bezeliansky which is the case that binds me.”
