  4. We believe that Legal Complexity is a key underlying dynamic
    The inability to scale human capital alone to the scope and
    complexity of legal rule systems
    Demand for Legal Technology, Design, Informatics, Process
    Engineering are (in part) responses to increasing legal
    complexity
    Relationship Between Legal Complexity and
    Legal Innovation
