… legal weapons reviews, as required by Article 36 of [AP I] are crucial. These require that States conduct legal reviews to establish, in each specific case, whether a weapon, means or method of warfare can be developed, acquired or used lawfully. Such reviews should also assess the legality of emerging weapons systems, including LAWS. We encourage all States to conduct such weapons reviews and we also encourage more regular and systematic exchange of information and sharing of national experiences on legal weapons reviews that would contribute to transparency and confidence building between States and development of best practices.
