  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
  5. WHAT IS Legal Complexity?

  6. HOW MIGHT WE MEASURE Legal Complexity?

  7. Daniel Martin Katz & Michael Bommarito, Measuring the complexity of

    the law: the United States Code, Artificial intelligence and law, 22(4), 337-374. (2014) Michael Bommarito & Daniel Martin Katz, A Mathematical Approach to the Study of the United States Code. Physica A: Statistical Mechanics and its Applications, 389 (19), 4195-4200 (2010).
  8. Here Katz/Bommarito ONLY investigated a single temporal snapshot of the

    2010 US Code in an effort to explore its complexity Daniel Martin Katz & Michael Bommarito, Measuring the complexity of the law: the United States Code, Artificial intelligence and law, 22(4), 337-374. (2014)

    characterize this as time ticks forward ? Research interest
