Lord Chief Justice Lord Judge said that while courts should always take the rulings of the Strasbourg-based court into account, they were not bound by them.
His comments are set to further fuel the debate over the human rights act, as a commission set up by David Cameron looks at the case for a British bill of rights.
But in giving evidence to the Lords constitution committee, a split over the issue emerged between two of Britain’s most senior judges.
Lord Phillips, the president of the Supreme Court and a former lord chief justice, told the peers: “In the end, Strasbourg is going to win so long as we have the human rights act, and the human rights act is designed to give effect to that part of the rule of law which says we must comply with the convention.
“If we have Strasbourg saying, ‘You can’t do that’, it raises some very real problems.”
But Lord Judge said: “I would like to say that maybe Strasbourg shouldn’t win and doesn’t need to win.”
He added: “For Strasbourg there is a debate yet to happen, it will have to happen in the Supreme Court, about what we really do mean in the human rights act, what parliament means in the human rights act, when it said that courts in this country must ‘take account’ of the decisions of the European Court of Human Rights.
“I myself think it’s at least arguable that, having taken account of the decision of the court in Strasbourg, our courts are not bound by them.
“We have to give them due weight, and in most cases obviously we would follow them, but not I think necessarily.”
