Section 4(4) of the Foreign Compensation Act 1950 stated: “The determination by the commission of any application made to them under this Act shall not be called into question in any court of law”
However the House of Lords determined that the ouster clause exempting the determination from legal review did not apply, as there was no valid determination in the first place.
So essentially if the tribunal were to make a determination consistent with the law then yes that wouldn't be subject to judicial review, but if they make an error of law then their determination is not valid and therefore is subject to review. Take that, parliamentary overreach!
