International treaties significantly impact local laws by establishing binding obligations on states that ratify them. These treaties can lead to the adaptation of domestic legislation, requiring states to align their laws with international standards, enhancing human rights, environmental protections, or trade standards. Depending on national legal frameworks, treaties can have direct or indirect effects on local law, influencing legal interpretations and providing grounds for judicial review. As a result, the interplay between international law and local legislation can either strengthen legal frameworks or create tensions, particularly in cases where sovereignty is perceived as at risk.
