With the growing number of international conflicts, it is crucial to know whether this expectation is met in practice. We examine the effect of the 2014 annexation of Crimea on the enforcement rate of foreign decisions by Russian and Ukrainian judges. We assemble novel data on the entire universe of Russian and Ukrainian court decisions concerning the enforcement of foreign decisions resolving cross-border commercial disputes. Using a difference-in-differences design, we find that the enforcement rate of Ukrainian (Russian) decisions in Russia (Ukraine) fell by 26% (33%) after the annexation. We show that courts increasingly justified refusals through discretionary legal grounds and undue-notification claims. Our findings provide the first causal evidence that international conflict affects both judicial decision-making and compliance with commercial treaties.
