Some of the latest criticisms come from Peru and Venezuela . Venezuela subsequently withdrew from the system after President Hugo Chávez declared the court 's decision to rule Venezuela guilty of holding a prisoner in " inhumane " jail conditions . Up to then , Trinidad and Tobago had been the only state to withdraw . Peru tried to do so , but did not follow the appropriate procedure . The last of these criticisms is directed against the Court 's decision in the case of the Mapiripán Massacre declaring that some people were murdered with the consent of the Colombian state , a few of whom were subsequently found alive
