Finally an answer in one of Harry's personal crusades By Rhiannon Mills, royal correspondent This is a case that meant so much to Prince Harry that he flew to the UK from America to hear for himself everything that was said in public and private during the two-day appeal. Security for him and his family, and the decision to take away their automatic right to police protection, has been one of the most contentious issues since he stepped away from royal life. In a nutshell - he was appealing against a High Court ruling that found the Home Office had acted lawfully when it decided to downgrade his level of security when he visits the UK, with it being assessed on a case by case basis. It was ruled last year that the Executive Committee for the Protection of Royalty and Public Figures' (Ravec) approach to the duke and his family's security was not "irrational" and was proportionate. In a two-day hearing in April, Harry's barristers told the Court of Appeal that he was "singled out" for "inferior treatment" and that his safety, security and life are "at stake". They say he has never asked for special treatment - just to be treated the same as other high profile individuals. The Home Office, which is legally responsible for Ravec's decisions, opposes the appeal. Its lawyers told the court Ravec's decision was taken in a "unique set of circumstances" and there was "no proper basis" for challenging it. It's clearly a very personal crusade for Harry. Following the hearing in April, he spoke to reporters, telling them he is aware that even if he wins he may not get what he wants, or get Ravec to change its policy, but he sees this as a point of principle. It also appears it is having an impact on his personal relationships. There have been suggestions his belief the King could have done more to help is one of the reasons for ongoing fractures in his relationship with his father.
