Tratado de doble nacionalidad — DESMENTIDO POSITIVO

No bilateral dual-nationality or sub-citizenship treaty confers Singapore nationality. ASEAN and Commonwealth membership create no nationality pathway (Art 139 Commonwealth-citizen status is a consequence of, not a route to, citizenship). Positive disconfirmation.

Evidence-pinned eligibility & rules:

• Commonwealth-citizen status under Art 139 is a STATUS attaching to existing Singapore citizens, not an acquisition route: every person who is a citizen of Singapore enjoys, by virtue of that citizenship, the status of a Commonwealth citizen in common with citizens of other Commonwealth countries. The Article confers no means of acquiring Singapore citizenship and operates only consequentially on persons who are already citizens. [Art 139(1)]
• Existing law applies to a citizen of the Republic of Ireland who is not also a Commonwealth citizen as it applies to a Commonwealth citizen, except so far as Parliament otherwise provides. This is a status-equivalence rule (a colonial-era Commonwealth-Ireland legacy provision), not a pathway for an Irish citizen to acquire Singapore citizenship. [Art 139(2)]
• POSITIVE DISCONFIRMATION: there is no bilateral or multilateral treaty conferring Singapore nationality. Membership in ASEAN and the Commonwealth does not create a sub-citizenship or any nationality-acquisition pathway; the modes of acquiring Singapore citizenship are exhaustively those listed in Art 120(2) — birth, descent, registration (or pre-Constitution enrolment), and naturalisation. No bilateral dual-nationality agreement exists. [Art 120(2); Art 139(1)]
