The Shrinking Supreme Court Docket:
Linda Greenhouse takes a look here.

  UPDATE: My favorite line from the story: "In private conversations, the justices themselves insist that nothing so profound is going on, but rather seem mystified at what they perceive as a paucity of cases that meet the court's standard criteria." I think this is right; I'm not aware of any juicy cases with clear splits and no vehicle problems that the Court inexplicably turned away. But even more interesting is the fact that Greenhouse would not only think to ask Justices their views of this problem, but would actually get answers from them for the paper. Now that's access.
