International treaties significantly shape national law as they can dictate legal obligations that nations must adhere to. Upon ratification, treaties often become part of a country’s domestic legal framework, influencing legislation and judicial interpretations. However, this relationship can vary based on whether a country adheres to a dualist or monist approach regarding international law. As such, treaties can drive significant changes in areas such as trade, environmental policy, and human rights, thereby impacting national governance and compliance with international norms.
