As you appear to be on a one man anti EU crusade with three similarly themed new threads in one morning, I have had the campaign vehicle POL'd and made ready for you.
Too much time and not enough to do. It's not morning here and the ECHR is not an EU institution.
I'm not here defending the pirates - but the court case was not about the charges that were preferred - it was the failure of France to comply with arrest procedures - and there are procedures in place to extend the period of arrest, which the French authorities didn't follow. If I was arrested by the French (or any other country subject to the ECHR), and I was held under these conditions - in effect, unlawfully - I'd be seeking recompense, too. Ain't it a b!tch to live in a society where there is the Rule of Law, with little political interference, with the inherent Right to appeal (qv 'Lee Rigby Muzzie Killers thread...blah, blah...). It's called a liberal democracy, get over it.
