Here is a sentence I wrote:
In 1937, the Judicial Committee of the Privy Council struck down Bennett’s New Deal legislation, ruling the reforms unconstitutional and outside of federal jurisdiction (Struthers 1983; ...).
Is the second part of it: ". . . ruling the reforms . . . outside of federal jurisdiction" idiomatic? I meant to say that the court ruled the reforms unconstitutional and affirmed that some of the reforms were not under federal authority, and so the federal government was not allowed to implement them.
Background: Bennett's legislation, called New Deal, consisted of several different policy reforms. The court "declared many of the reforms unconstitutional and outside of federal jurisdiction."
