7.3 Immunities of Special Missions

Special missions — temporary delegations for a particular task (negotiations, summits, state funerals) — governed by the New York Convention on Special Missions (1969) (modest ratifications; much accepted as custom): consent-based entry (the sovereignty gate); the head of delegation and diplomatic staff enjoy immunity equivalent to VCDR diplomats while the mission lasts; premises' inviolability. The margins: ad hoc envoys' uncertain status; high-level visits (the visiting head of government's complete inviolability); UN conference delegates' regime. The practical Nepali note: the summit-and-conference era (SAARC, BIMSTEC, BRI forums) runs on special-mission immunity — the state protocol manuals codifying the custom.
