When is the Guinea-Bissau referendum 2026?

Polling day is 2026-08-30 (officially set).

When will the final result of the Referendum on the entry into force of the new Constitution of the Republic: "Concorda com a entrada em vigor da nova Constituição da República aprovada pelo Conselho Nacional de Transição?" race be official?

Expected between 2026-09-03T00:00:00Z and 2026-09-30T23:59:59Z (UTC), confidence estimate. ESTIMATE. The CNE homologates its provisional count as definitive once the appeal deadlines pass without a challenge. Under the electoral law (arts. 142-147, assumed to apply by analogy) appeals to the Supreme Court of Justice plenary are lodged within 48 h, answered within 48 h and decided within a further 48 h; no referendum-specific deadline was found because the Referendum Law text is not online. The window opens two days after the provisional count and closes at the end of 30 Sep 2026, deliberately late to allow for an appeal. Happened: in a communiqué of Thu 3 Sep 2026 the CNE declared the 1 Sep figures definitive, 'Não havendo reclamações ou impugnações sobre a votação e o apuramento, os dados proclamados no passado dia 1 de Setembro foram homologados como definitivos', and sent the general count record to the organs of sovereignty (ANG, 4 Sep 2026). The time of day is unknown, so replacedAt on the provisional stage uses midday. Press report only; the communiqué was not found on cne.gw, so observedAt is not set. No court-validation step was found: the Supreme Court proposed the convocation of the referendum (per the decree, ANG 6 Jul 2026) but no source reports it having to confirm the result.

The CNE's national count, which it called provisional. There is no official running count on the night. On Mon 31 Aug 2026 CNE executive secretary Idriça Djaló said the CNE 'prevê a divulgação dos resultados provisórios ... na terça feira (01)' (ANG, 31 Aug 2026). The window is that announced day (local time = UTC). For elections, electoral law art. 94 allows up to 10 days ('Entre 7 a 10 dias a contar da data do encerramento da votação'); the Referendum Law text was not found, so its own deadline is unknown. Happened: the CNE president announced the general count at a ceremony on Tue 1 Sep 2026: Yes 383,116 (70%), No 160,954 (30%), 572,712 voters of 914,428 registered (Jornal Nô Pintcha, 1 Sep 2026; ANG, 1-2 Sep 2026, which prints slightly different totals). Press reports only; not seen on cne.gw, so observedAt is not set. Polls: opened 07:00 (ANG, 30 Aug 2026) and closed 17:00 GMT (Euronews, 30 Aug 2026; electoral law art. 69).
Replaced on the live page by the final result from Thu 3 Sept, 12:00.
