"In view of my conclusion as to the jurisdiction of the court in a case under the LRA 1925, the question arises whether that jurisdiction has been abrogated or otherwise affected by the 2002 Act. The first thing to notice is that there is no provision in the 2002 Act which expressly so provides. Accordingly, one could only hold that the earlier jurisdiction has been abrogated or otherwise affected by the 2002 Act if its continued existence in its original form were incompatible with the scheme of the 2002 Act. In order to consider such a possibility it was necessary to consider, as I have done, the provisions of the LRA 1925 and of the LCA 1925 and of the LCA 1972 to see why it was the case that those statutory provisions were not considered to be incompatible with the inherent jurisdiction. In my judgment, there is no sufficient change of substance between the earlier provisions and the provisions now in the 2002 Act which would justify the conclusion that the existence of the inherent jurisdiction is incompatible with the 2002 Act, whereas it was compatible with the earlier legislation. I conclude that the jurisdiction, recognised and developed by the courts, in relation to the vacation of cautions registered under the LRA 1925, applies also in relation to unilateral notices registered under the 2002 Act. That jurisdiction applied in different ways in relation to cautions to protect claims which were unsustainable and in relation to cautions to protect claims which were well arguable. In the present case, on the material before me, the claimants claim is well arguable. Accordingly, I cannot order the cancellation of the unilateral notice on the ground that his claim is without substance. The earlier cases where the underlying claim was well arguable only went so far as to require an undertaking in damages from the beneficiary of the caution, as a condition of keeping the caution in place. However, the clear philosophy of those cases was that the court should not allow the beneficiary of the notice to have the protection of the notice pending trial without the court considering the position of the registered proprietor and whether, and if so how, the proprietor should be protected pending trial. The court proceeded on the basis of an analogy with the position it would adopt if the beneficiary of the notice had, instead of registering a notice, applied for an interim injunction. I will therefore consider, in accordance with the philosophy in the earlier cases what the court would do, as between these parties, if the claimant applied for an interim injunction pending trial and, in that context, I will take into account any adverse effect on the defendant of the court granting such an injunction."
"If the Laws were to act wrongfully in withholding a certificate referred to in the restriction, then the Haiders could take steps to remedy the position. They could apply to the registrar to disapply the restriction. That procedure might take time if the Laws objected and the objection had to be determined by the FtT. Another possibility would be for the Haiders to apply in the Chancery Division for an order vacating the restriction under the jurisdiction recognised in Nugent v Nugent[2015] Ch 121 . That jurisdiction can be exercised on an interim application to the court and the established practice is to adopt a robust approach to the determination of any issues between the parties. Further, if the Laws showed that they had an arguable case to maintain the restriction, the court would have power to permit the restriction to remain but only if the Laws gave an undertaking in damages."
''… it is a maxim in the common law that a statute made in the affirmative without any negative expressed or implied doth not take away the common law.'
"The way in which the inherent jurisdiction may be exercised depends on the court's assessment of the claim to the alleged interest which is sought to be protected by the unilateral notice. If the claim lacks substance, then the court can vacate the unilateral notice without more ado. In a clear case, the jurisdiction can be exercised on an interim application without a trial and a robust approach is appropriate. The authority which encourages the court to adopt a robust approach is The Rawlplug Co Ltd v Kamvale Properties Ltd. If the claim has some substance, then the court approaches the matter in the same way as it would an application, by the party who has entered the unilateral notice, for an injunction restraining the registered proprietor from dealing with the property in a way which was incompatible with the claim, until the claim is determined. If the court is persuaded that the case is one where the registered proprietor ought to be restrained from dealing with the property in that way, then the court normally allows the entry to remain on the register but only on terms that the person with the benefit of the entry on the register undertakes to the court to pay compensation to the registered proprietor if it should transpire that the claim fails and the entry ought not to have been made. This undertaking is the equivalent of the undertaking in damages which a claimant is required to give in a case where the claimant obtains an interim injunction."
