Guantánamo case: What is the reason for the denial of legal action?

This case was one of worldwide recognition because of the barbarities that were taking place in that prison and to which no international support entity could provide a solution due to the political or governmental irregularities under which the country where it was located: Cuba, was governed. Many external actors tried to demonstrate that the prison subjugation was not approved and the violation of human rights was a key factor for its closure.
