Most Canadians do not realize the horrifying implications of Canada's support for NATO's “first use" policy. The policy should be made an object of public examination and debate. It should be challenged, and that's exactly what the Nuclear Weapons Legal Action is aiming to do. If governments will not act more decisively against the nuclear danger, the public must. Over the past few years public opinion world-wide has been mounting against nuclear weapons. A strong consensus is emerging that it is intolerable for the whole human race to have to live continuously under the shadow of nuclear weapons and the threat of nuclear war. As the peace movement has raised public awareness of nuclear issues, many more lawyers and academics have published articles on the illegality of nuclear weapons. Two years ago they were even joined by the president of the Canadian Bar Association, Claude Thompson, who told an internationai audience in Berlin, "nuclear weapons are illegal because they have the potential to destroy us all." There is now a rapidly growing body of legal opinion that nuclear weapons, in addition to being dangerous and immoral, would also violate international law if used. When such a massive shift in public attitude occurs, and the new consensus can be grounded on established legal principles, the prospects for using the courts to achieve social change become increasingly favourable. Courts don't make law, but they do interpret law and assign weight and significance to the various elements presented in a case. Such interpretations are often qualititative, and so are subject to the influence of the social milieu, the "times." Even when the law remains static, its meaning can change. As the times change, so do court decisions. If it is true, as So many lawyers have been saying, that the use of nuclear weapons would be illegal, it should be possible to challenge Canada's policies in court, The Nuclear Weapons Legal Action is organizing that court challenge. The Nuclear Weapons Legal Action is above all an effort to give the courts a chance to act by presenting them with a case in law for declaring the illegitimacy of NATO's plans to use nuclear weapons. With the impressive and growing body of legal opinion, the time is ripe for the question of the legality of nuciear weapons to be heard in a court of law. There have already been a few successful cases in other countries. In Illinois v. Jarka in the U.S., demonsirators at a naval base who had been charged with resisting arrest were acquitted on the defence of “necessity” on the grounds that use or threatened use of nuclear weapons violates international law. In most cases, however, (such as in Bnitain, the U.S. and The Netherlands} where the legality of nuclear weapons has been at issue, the courts have avoided the question by ruling that they lack jurisdiction to review government decisions in foreign policy or defence matters.
