If the nature of the law, is such as to continually breach international law, and companies are consistently and successfully challenging that law, a state may feel pressured to either: 1. Withdraw from the free trade agreement, or 2. change its laws to conform to the terms of the free trade agreement. This is not a bug but a feature: the ISDS is designed to ensure that states abide by international law and respect the terms of the free trade agreement they consented to. This is fully in line with the concept of pacta sunt servanda and the relationship between international and municipal law. Finally, if you are the United States, you can also simply ignore the arbitral tribunal and continue to be in breach of the agreement and international law, because, well, what are they gonna do?
