The international court of justice of the UN is located in the Peace Palace. The Peace Palace is in the Hague, Netherlands. This court helps to settle international disputes. This court consists of 15 different judges from various nations, who serve a nine year term. Along with settling disputes, countries can use this court as a way to gain outside legal advice on domestic cases.
Well according to how the 15th amendment went i think that they were happy because it gave some some more freedom or rights to be able to vote and give an opinion of what they want. It defiantly was a good thing.
