how do the functions of the ICJ differ from those of the International Criminal Court?

Answer 1

The International Court of Justice has jurisdiction over all disputes involving international entities unlike the Internationa Criminal Court whose jurisdiction involves only the trial of crimes involving international issues.

Answer 2

The International Court of Justice is basically an arbitrator that resolves disputes between two or more nations. It functions as an international settlement court to help bring closer to disputes or issues that the nations could not handle themselves.

The International Criminal Court is a criminal court that tries individuals (people) for crimes of an international nature. The Lockerbie bombing would be an example of this. This court can try people who have criminal actions against a country or have violated an international law, like a human rights violation.
