A more thorough explanation:

The Central American Court of Justice was a court established by a convention in 1908 between five countries: Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. The purpose of the court was to ensure that these countries maintained peaceful relations and did not resort to using force against each other.

For example, if one country felt that another country was violating their rights or causing harm, they could bring their case to the Central American Court of Justice instead of taking matters into their own hands. This helped to prevent conflicts and promote cooperation between the countries.

However, the convention that created the court only lasted for ten years, and the court ceased to exist in 1918.
