key case: R (Lord Carlile) v Secretary of State for the Home Dept
Home Secretary had excluded a dissident Iranian politician, Maryam Rajavi (who was living in Paris), from the UK. She had been invited by Lord Carlile and two other members of the House of Lords to address a meeting in Westminster, but an exclusion order had been upheld. Mrs Rajavi had links to a formerly proscribed organisation and the Home Secretary was concerned that there could be repercussions in relation to general UK-Iranian political relations. Article 10 interests had been engaged. However, with the exception of Lord Toulson, who dissented, the justices held that the interference had been proportionate. Essentially the majority believed that the Article 10 rights engaged were not sufficiently significant to put at risk what Lady Hale called the UK's 'fragile but imperative' relationship with Iran
