The Bureau of the Human Rights Council has released in February a new proposal for the list of speakers. This proposal is very similar to the second proposal dated last November.
In this new proposal, States indicate by email, two weeks before the UPR session, on which States under Review (SuR) they wish to intervene. Then the Bureau lists States inscribed by SuR and by alphabetical order. Finally it is decided, by drawing of lots, which State on each list will take the floor first followed by the rest of them.
