Most Important U.S. Supreme Court Decision of the term (of the decade?) due on Monday

On Monday (maybe as late as Tuesday), we'll find out if the rule of law still exists in the United States, when this case is decided. The issue is fairly simple: can the President of the United States, without any review by the courts, arrest United States citizens and hold them in communicado and indefinitely? If the answer is yes, then we're all doomed. The "rule of law" is a complex ideal, but a de minimus requirement on all understandings is that there is independent review of official actions that infringe upon fundamental rights and liberties. I am hopeful the Supreme Court will do the right thing in this case, given how fundamental the values are that are at stake.

UPDATE: According to this site, the decision could come as late as Thursday.
