Observer Status to States

Observer status is a privilege granted by some organizations to non-members to give them an ability to participate in the organization’s activities. Observer status is often granted by intergovernmental organizations (IGO) to non-member parties and international nongovernmental organizations (INGO) that have an interest in the IGO’s activities. Observers generally have a limited ability to participate in the IGO, lacking the ability to vote or propose resolutions.
