Latest developments

Switzerland maintains policies and practices that are compatible with all of the prohibitions in Article 1 of the TPNW, and can therefore sign and ratify or accede to the Treaty without the need for a change in conduct.

In the First Committee of the 2021 UN General Assembly, Switzerland said that it will participate as an observer in the First Meeting of States Parties to the TPNW in 2022. It added: 'Irrespective of the still open question of Switzerland’s accession to the TPNW, we are ready to contribute to a constructive relationship between the NPT and the TPNW. We also emphasise that the humanitarian consequences must remain a driving force for nuclear disarmament.'1

In June 2018, the Swiss Government published an interdepartmental working group (IDAG) report on the implications of accession to the TPNW. 'At the current stage', the report concluded, 'the reasons against an accession of Switzerland outweigh the potential opportunities accompanying a signature and ratification of this treaty.' Both houses of the Swiss Parliament subsequently instructed the government to sign and ratify without delay.2 The Swiss Government plans to update the IDAG report and review its decision after the NPT Review Conference, expected to be held in 2022, and contends that this fulfils the mandate given by Parliament. Parliament and NGOs disagree.

Responding to a question in Parliament on 16 March 2021, the head of the foreign ministry, Ignazio Cassis, said that 'there will be no problem in joining this treaty' if concerns expressed by some other states about the Treaty’s impact on the NPT are 'abandoned'.3

Recommendations

  • Switzerland should urgently adhere to the TPNW.
