It's clear to me, even as a lay person, that Levinson's statement does not refer to any statutory text. Or any legal procedure, etc. On what grounds was he objecting?

"A party does not go far enough by raising a non-specific objection or claim"

Obviously Levison is attempting to argue that the pen/trap statute is limited to specific information ("metatdata") and it does not allow interception of "all of the secure communications [and] administrative traffic".

That he didn't cite the chapter and verse which this contradicts seems like an situation where he needed a real defense lawyer.
