The vote
From the opinions
“I part ways with the Court, however, when it concludes that 49 U. S. C. §114(r)(1) does not itself prohibit the type of disclosure at issue here-the release of information regarding the absence of federal air marshals on overnight flights.”
What's next
The Federal Circuit’s ruling remains in place; no further step in this case is identified.
