This article for the New York Times by Adam Liptak discusses the upcoming Supreme Court hearings about whether the 2010 health care act is unconstitutional. The story focuses on a strange potential obstacle for this case that is based on a law passed in 1867. The law says that a court cannot have a case based on taxes that will be paid in the future. According to some this means the court cannot hear the case until 2015 when the penalties from the health care act are actually paid.
The argument in this story seems to be that this 1867 law will not actually impede the Supreme Court from hearing the case. Whether the law applies is certainly disputed and the Supreme Court can decide either way, but Liptak seems to suggest that they will likely choose to hear the case. This is a fact claim that Liptak uses logos proofs as evidence. He cites the fact that Congress can simply amend the law and that the Supreme Court will likely not want to have to hear the case again in only a short while.
