The problem I see is that until the lawsuit gets to at least the Federal District Court level it is pretty much a very local matter with no indication of becoming anything bigger. A section devoted to (almost) all lawsuits filed could get clogged up pretty quickly.
The other problem I forsee is the updating of any lawsuit posted. Some folks know how to do legal research and have the resources to do it, while others may be limited to Google and pure luck. Unless someone was "in charge" and kept the updates in order with each case as a separate stickey I am very worried that mass confusion would reign. But then I am a copybook order-and-control freak when it comes to case review.
Tracking down, let alone tracking, promising cases in any one state would seem to be a near-monumental task. Doing so on a nation-wide basis makes my teeth ache just thinkking about the amount of work it would need.
Anybody with ideas of how to manage the task, as opposed to merely saying "It's a neat idea" is encouraged to chime up.
stay safe.
