You can take a convention State to court if one of its ships causes pollution damage. The State is considered to have given up its right to claim it is sovereign and cannot be sued. This applies if the State is a CLC State and the damage is from oil, or a Bunker Oil Convention State and the damage is from bunker oil. You cannot take the property of a convention State to pay for the damage. The court can still make a decision about the damage, but it cannot force the State to give up its property. This rule is about ships owned by convention States and pollution damage. If you are suing under section 345 or 346 for pollution damage, the convention State is treated as if it has agreed to the court's jurisdiction. This means the court can hear the case and make a decision. The convention State has effectively waived its right to claim it is sovereign and cannot be sued, in certain circumstances, such as when the pollution damage is from oil or bunker oil.
