I keep thinking that there may be a new subset of IT Law called Network Law, interested with the formation, regulation, and study of networks. An article in The Economist is making the usual rounds through the blogosphere describing an interesting paper by Seth Chandler of the University of Houston, where he maps the network of U.S. Supreme Court decisions and discovers that there is a scale-free topology at work. Apparently, some older cases about Federal Jurisdiction are the hubs on the network.
This is yet another interesting use of the mathematics of networks. I am sure that in the near future there will be many other applications for such studies in the law.
