A comparison of decisions in the US, Europe, Colombia, Indonesia, Israel, and elsewhere reveals that, rather than issuing declarations of constitutional incompatibility, courts are more likely to respond to constitutional tensions indirectly. Their rulings adopt stances that range from hard deference (such as the Peruvian Constitutional Court viewing constitutional law and investment law as entirely compatible) to soft defiance (for example the Colombian Constitutional Court requiring only modest renegotiation of some treaty terms so that they are constitutionally compliant). Readers learn that judges are not aiming to undermine the investment law regime but are seeking to mitigate constitutional collision.
