UN General Assembly First Committee adopts Resolution L.56 on autonomous weapons (1 November 2023)

On Wednesday 1 November 2023, the United Nations General Assembly's First Committee — the disarmament and international security committee — adopted draft resolution L.56 on lethal autonomous weapons systems by 164 votes in favour, 5 against, and 8 abstaining. The resolution, tabled by Austria with 43 co-sponsoring states, was the first stand-alone resolution on autonomous weapons systems ever adopted by a UN General Assembly body and the moment at which the file moved from the consensus-blocked Convention on Certain Conventional Weapons (CCW) track in Geneva to a majority-voting UN General Assembly process in New York. For the Campaign to Stop Killer Robots, a coalition then of more than 250 non-governmental organisations across 70 countries, the vote was the strategic break the campaign had been working toward for more than a decade — the moment described in the coalition's own account as "a decision to put the issue squarely on the diplomatic agenda of the General Assembly" — and the proximate cause of the UN Secretary-General report that would follow nine months later.

Context

The resolution arrived after roughly nine years of multilateral discussion under the Convention on Certain Conventional Weapons in Geneva, where the campaign's first decade had been spent — first in informal expert meetings (87 states attended the first such meeting in May 2014) and then, from December 2016, under a formal Group of Governmental Experts mandate. The CCW operates by consensus, and through the late 2010s a small number of states — including, on the campaign's account, the United States, Russia, the United Kingdom, Israel, and South Korea — used the consensus rule to block movement toward a negotiating mandate.

By 2023 a substantial cross-regional bloc of states had begun working the parallel UN General Assembly track. In February 2023, 33 Latin American and Caribbean states issued the Belén Communiqué in Costa Rica calling for urgent negotiation of a legally binding instrument — a regional bloc commitment that established the political plausibility of moving the file out of the CCW. The Austrian Foreign Ministry, working with national coalitions and the Stop Killer Robots Steering Committee, drafted what became draft resolution L.56 over the subsequent months and tabled it in the First Committee for the 78th session of the General Assembly.

What happened on the day

The First Committee took up draft resolution L.56 on the afternoon of 1 November 2023, in the General Assembly chamber at UN Headquarters in New York. The resolution was adopted by a recorded vote of 164 in favour, 5 against, and 8 abstaining.

The 43 co-sponsoring states named in the coalition's own contemporaneous record were: Antigua and Barbuda, Austria, the Bahamas, Barbados, Belgium, Belize, Bulgaria, Cabo Verde, Costa Rica, Croatia, Cyprus, Czechia, Denmark, the Dominican Republic, Ecuador, Fiji, Germany, Guatemala, Honduras, Hungary, Iceland, Ireland, Italy, Kazakhstan, Kiribati, Liechtenstein, Luxembourg, the Maldives, Malta, Mexico, Montenegro, the Netherlands, New Zealand, North Macedonia, Norway, the Philippines, the Republic of Moldova, San Marino, Sierra Leone, Slovenia, Sri Lanka, Switzerland, and Trinidad and Tobago. The co-sponsor list spans Europe (continental and Nordic), Latin America and the Caribbean, the Pacific, sub-Saharan Africa, Central Asia, and South Asia — the cross-regional spread that the campaign had identified as the threshold for moving the file out of the CCW.

Substantively, the resolution stressed "the urgent need for the international community to address the challenges and concerns raised by autonomous weapons systems," noted concerns including the possibility of these systems lowering the threshold for conflict and contributing to proliferation, and requested the UN Secretary-General to prepare a report reflecting the views of member states on the humanitarian, legal, security, technological, and ethical concerns raised by autonomous weapons systems and on possible approaches to addressing them. The resolution also placed "Lethal autonomous weapons systems" on the General Assembly's agenda for the following session — the procedural step that converted what had been a Geneva-track topic into a New York-track topic with annual standing.

The campaign's public framing of the day was the #VoteAgainstTheMachine hashtag and the coalition's own headline figure: 164 states "vote against the machine", with the coalition committing that it "will not cease pushing for this outcome" until a binding international instrument is in place.

Significance

The 1 November 2023 vote is the corpus's first UN-anchored Event and the first multilateral-policy adoption in the events slice. Where the 22-23 April 2013 London launch sits at the founding edge of the Stop Killer Robots campaign — civil society putting its case to the international diplomatic and press community for the first time — the 1 November 2023 First Committee vote sits at the strategic-break edge of the same campaign, the moment at which the diplomatic case the 2013 launch had begun to make became a numbered UN resolution adopted by an overwhelming majority of states. Read alongside the Resolution 79/62 plenary vote of December 2024, the 12-13 May 2025 informal consultations in New York, and the 42-state joint statement read by Brazil at the September 2025 GGE, the 1 November 2023 vote is the first move in a two-year sequence that has now produced a UN General Assembly process explicitly aimed at concluding treaty negotiations by 2026.

The First Committee vote also opened the procedural pathway by which the resolution would be adopted, in materially the same form, by the General Assembly plenary on 22 December 2023 as Resolution 78/241 by a vote of 152 in favour, 4 against, and 11 abstentions — the numbered UNGA resolution that subsequent campaign documents, including the UN Secretary-General's August 2024 report A/79/88 reiterating the call on states to conclude a treaty by 2026, would cite as the founding mandate.

For the broader make-AI-good movement that this corpus is mapping, the vote matters on two further counts. First, it is the first time a UN General Assembly body had taken a formal, named position on the governance of an AI-defined class of military technology — a procedural achievement that newer AI-policy organising elsewhere in the corpus, including youth-led groups such as Encode Justice working on US federal restrictions on AI in nuclear-weapons command-and-control, has explicitly cited as part of its inheritance. Second, the vote demonstrates that the humanitarian-disarmament template — a sustained civil-society coalition pairing UN advocacy with public-facing engagement of faith communities, scientists, parliamentarians, and survivors — can produce a UN General Assembly resolution on an AI-governance topic, on a timescale (twelve years from the campaign's founding meeting in October 2012 to the November 2023 vote) that is long but trackable. Whether that template produces a signed treaty by the Secretary-General's stated 2026 deadline is the open question against which the next two years of corpus entries will continue to test.
