I agree that it is getting long.  I took out some of the history of the legislation (perhaps that should go to health care reform in the United States?) and repetition in the section on legal challenges. Many of the challenges seem basically on the same grounds so I merged the text and kept the references. This does unforunateöy drop the names of the states, but perhaps they could be added as a note in a reference. I don't believe that I have merged challenges based on other reasons, but if I have I apologize.  I think there are just 2 or 3 legal bases being cited right now. The history of the challenges (which state challenged when is not terribly revealing and it was becoming repetitive so I tried as much as possible to get that out.  If someone else could re-arrange it to show what the main challenged are that would be helpful.  If I had the time I'd move on to the court decisions, which I feel sure could be merged with the legal challenges section.
