mr100percent's Journal: John Walker's law amended?

John Walker Lindh was charged and convicted under a Clinton-era law that prohbited providing support to people like the Taliban. I'm not a lawyer, but it appears as if the law was just challenged, assuming it's the same one.

From The Washington Post:

"A federal appeals court ruled yesterday that the government cannot convict groups or individuals of violating a federal law against "material support" for terrorist organizations unless it proves beyond a reasonable doubt that they knew the organizations were involved in terrorist activity."

From what I've read of Lindh's plea, this could have exonerated him. The article makes it clear that this was a 1996 law, could it be the same one?
