Dinah Rose QC is a human rights lawyer of great distinction. A former Barrister of the Year, she has appeared in several high profile cases, ranging from extraordinary rendition and Julian Assange to the admissions policy of the Jewish Free School. After the Jimmy Savile scandal, the BBC appointed her to investigate bullying and sexual harassment among its staff. She resigned on principle from the Liberal Democrats in protest at Nick Clegg’s support for the secrecy provisions of the Coalition’s Justice and Security Act 2013. An admirer of Lord Pannick and the late Lord Lester, scourges of authoritarian governments, she is a pillar of the liberal legal establishment. Why, then, is Ms Rose suddenly under fire from Stonewall and other LGBT lobby groups? There are two reasons. The first is that she is representing the Cayman Islands in a case brought by a lesbian couple that has now reached the Privy Council, the final court of appeal for many Caribbean jurisdictions. Her critics claim that she is helping the Cayman government to ban same sex marriage. Edwin Cameron, a former South African judge, has accused her of litigating “on behalf of homophobia in the Caribbean”.
