About LAWYERS COMMITTEE ON NUCLEAR POLICY INC

Founded in 1981, the Lawyers Committee on Nuclear Policy (LCNP) is a U.S.-based 501(c)(3) educational association of lawyers and legal scholars that provides legal and policy analysis aimed at the abolition of nuclear weapons and stronger compliance with international law. LCNP serves as the UN office of the International Association of Lawyers Against Nuclear Arms (IALANA), regularly submits legal analyses and statements to UN and treaty deliberations (including NPT and TPNW processes), and organizes conferences, briefings, and publications for policymakers, diplomats, civil society, and the media. In the last three years LCNP has remained active with policy reports, public statements, and conferences — for example organizing a November 8, 2023 conference on nuclear weapons and international law and publishing research and advocacy material (including a May 2024 report on missile and strategic procurement risks) — while maintaining a small staff and board of experienced legal professionals and scholars.
