Regulatory rules are omnipresent today. Increasingly, they also influence private rights and obligations, from employment contracts to competition law and data protection. Private international law traditionally treats them with a certain reserve because they do not fit its paradigms of “neutral” and “interchangeable” rules of law. This article argues that it is time to change this attitude. Regulatory rules often protect global public goods, such as the environment, or shield against global bads, such as pandemics. [---]
