U.S. Judge Audrey Collins ruled that a section of the USA Patriot Act barring “expert advice or assistance” to groups designated foreign terrorists organizations is unconstitutionally vague.

“The ruling marks the first court decision to declare a part of the post-September 11, 2001 anti-terrorism statute unconstitutional, said David Cole, a Georgetown University law professor who argued the case on behalf of the Humanitarian Law Project,” reported The Associated Press.

The judge ruled the ban on providing “expert advice or assistance” is in violation of the First and Fifth Amendments to the Constitution.
