This document discusses enhancing mutual trust and interface between actors in conflict of laws through repeated interaction. It criticizes the conventional focus on territorial connections in conflict of laws as less relevant due to global communication networks. Rather than authority-based vertical relations, the document advocates establishing horizontal interface and mutual trust among peers in different systems through repetitive cooperation over time. As an example, it notes patent offices have developed mutual trust and information exchange through repeated examination work on similar technologies and cases. The document argues this approach can help address limitations of conventional conflict of laws tools.
