Legal review of weapons and IHL

Parties to an armed conflict are limited by the rules of international humanitarian law in their choice of weapons, and in the means and methods of warfare they employ. 

When developing or acquiring new weapons, states should determine whether they comply with these rules. Ongoing technological advances mean that it continues to be vitally important to assess the legality of new weapons.
