Which of the following statement (s) is are correct NOT about The International Court of Justice ('ICJ')?

There is no category of cases which are required to refer to the court compulsorily.

The court may have jurisdiction to decide cases in which the parties agree to appear before the court, on their own behest, and agree to be bound by the decision of the ICJ. The court may also be a forum if provided for in a treaty between parties and in certain cases it is compulsory to refer to the court with regards to certain disputes. The court may also give advisory opinions under Articles 65-68 of the Statute of the ICJ to countries. These are not binding but are merely referrals to the ICJ to understand the point of law on the matter. The ICJ is thus, one of the primary sources of dispute resolution available with regards to international disputes when parties are agreeable to settle them on their own accord
