An EU court has ruled for the third time that European Union countries are wrong to freeze the funds of an Iranian opposition group that has been placed on the bloc's list of terrorist organizations. The European Court of First Instance says the rights of defense of the People's Mujahedeen Organization of Iran were violated and that the EU nations did not provide sufficient proof to back their move to blacklist the group. The court's ruling , issued Thursday, is the latest development in a legal showdown between the Iranian group and the 27-nation bloc. The Paris-based group says it is not a terrorist organization and it has waged a six-year legal battle in the EU's court to clear its name. EU countries have refused to conform to two previous rulings.
