These were 3 cases where the secretary of state granted planning permission himself under various statutes, and local protesters argued that this breached their convention rights to have civil rights and obligations determined by an independent and impartial tribunal, under Article 6 of ECHR. HL said these powers were subject to judicial review which would be by an independent tribunal so that the actual powers conferred on the secretary of state were NOT in breach of article 6 ECHR.
Lord Slynn: the Home Secretary is not really usurping a judicial function since it is for the executive to decide what is in the interests of the country regarding planning restrictions. The common law has developed judicial review of such executive actions, so that ultimately an “independent tribunal” will have control. He also reiterates that mistake of fact can be a grounds for judicial review.
Lord Clyde: He declines to comment on the precise scope of judicial review.
