This procedure relies on a member in a minority fearing that raising an objection will expose it to the charge of obstructiveness and, thereby, the perils of isolation.
Silence procedure is employed by NATO, the OSCE, in the framework of the Common Foreign and Security Policy of the European Union (EU) and, no doubt, in numerous other international bodies.
Organisations making extensive use of the procedure are, among others, the European Union, NATO and the Organization for Security and Co-operation in Europe (OSCE).
If no amendments are proposed (if no one 'breaks the silence') before the deadline of the procedure, the text is considered adopted by all participants.
'Breaking the silence' is only a last resort in case a participant still has fundamental problems with parts of the text and is therefore the exception rather than the rule.
