Dear colleagues,

in the doctrinal literature usually three sui generis subjects of international law are mentioned:

Holy See, ICRC and the Sovreign Order of Malta.

My question is, do you know about any other entities of their own kind, that possess international legal personality, but do not fall under any category of subjects of international law (state, international organisation, insurrectional movement, individual...)

Other question is, is ICRC really a subject sui generis, when its subjectivity is based namely on Geneva Convention, but these themselves are recognizing that this legal status may apply also to "other impartial humanitarian organization"

Thank you for your opinions and answers.
