Three key components of the UN’s internal justice system are the Office of Staff Legal Assistance (OSLA), the UN Dispute Tribunal (UNDT) and the UN Appeals Tribunal (UNAT).

The table below lists which staff can make use of each of the three components and which cannot. Note that all staff listed below can appeal to the UN Appeals Tribunal, but some staff from some entities can appeal administrative decisions directly to UNAT without applying to the UNDT first. The UN Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) has its own dispute tribunal. The decisions of the UNRWA Dispute Tribunal can be appealed to UNAT.
