LONDON (AP) — Prince William and Kate Middleton’s aggressive legal strategy over topless photos of Britain’s likely future queen is the first salvo in what could be a decades-long tug-of-war over their family’s privacy.

A French court ruled in favor of the royal couple on Tuesday in their fight over the photos, but the scope of that ruling will be limited.

The unauthorized topless photos of Kate have already been widely published in France, Italy, Ireland and on the Internet.
