“100. In the present case, the mere fact that the Vice President of the Appeal Tribunal was sitting in London when he refused Mr Tehrani's application for leave to appeal does not mean that his decision is the decision of an English tribunal. The Appeal Tribunal was the creature of the 1999 Act which extends to the whole of the United Kingdom. Under para 6(1) of Schedule 2 to that Act, the Tribunal had to sit anywhere that the Lord Chancellor directed. Until 2002, it was indeed in the habit of sitting outside London - in Cardiff and in Glasgow, for instance - when that was convenient to the parties and their advisers. In 2002, in order to save time and to improve the efficiency of its operations, the tribunal adopted the practice of sitting in London and using video links to take submissions from representatives in other centres, such as Glasgow. But, equally, in theory at least, the tribunal could have set up its main offices in, say, Aberystwyth or Aberdeen and conducted the bulk of its hearings by video link to centres in England. However it arranged its operations and wherever it sat, the Appeal Tribunal remained the same and the law which it applied remained exactly the same. It was, in essence, a United Kingdom body, capable of sitting throughout the United Kingdom and applying exactly the same law throughout the United Kingdom based on a statute extending to the whole of the United Kingdom. Since the law applied by the Appeal Tribunal is just as much part of the law of Scotland as part of the law of England, when called upon to do so, the Court of Session is fully equipped to carry out the core function of judicial review, which is to ensure that the decision-maker acts within, and in accordance with, his legal powers. In that situation it would be much too crude an approach for the Court of Session to regard the Appeal Tribunal as a foreign tribunal for purposes of judicial review simply because it took a decision in London or Cardiff, but as a Scottish tribunal, within the scope of the court's jurisdiction, simply because it took a decision in Glasgow.” 101. If it would be wrong to rely simply on the place where the Appeal Tribunal took its decision as determining the jurisdiction of the Court of Session, it would be equally wrong to go to the opposite extreme and to assert that in all cases all the United Kingdom courts enjoy concurrent jurisdiction to review the decisions of the tribunal just because the tribunal could sit and apply the same law in all parts of the United Kingdom. So, for instance, where the asylum seeker was given limited leave to enter at an English port, was living in England, appealed to an adjudicator sitting in England, was refused leave to appeal by the Appeal Tribunal in England and was liable to be removed from England, there would be no basis for saying that the Court of Session had power to interfere in such wholly English proceedings by judicially reviewing the decision of the Appeal Tribunal.”
