“Silence is a source of great strength.” In principle, this is also true for the area of law. But the way this strength unfolds itself is a double-edged sword. On the one hand, silence in legal provisions ensures flexibility, so that the provisions readily adapt to new developments and circumstances. On the other hand, the ampler the amount of silence in a provision, the easier it can be subject to arbitrariness and misuse. This dilemma is particularly acute in anti-subsidy law. Here, an imprecise legal framework, additionally afflicted with lacunae, makes the anti-subsidy remedy an easy means for WTO members to implement protectionist interests.
