Honduras) – Application by Guatemala for Permission to Intervene. The ICJ has traditionally been extremely cautious in permitting third-state interventions in cases, but it has now responded to ongoing critiques of that position and has opened up the possibilities for intervention in meaningful ways. In some ways, it may have shifted its approach to intervention toward a more permissive model, similar to that of many constitutional courts.
