This seems to be the core point here — the US Code is a whitelist, not a blacklist: "The government's position also produces a wholly different kind of absurdity: the idea that the First Congress might so thoroughly undermine fundamental principles of the Constitution that many of its members had personally just helped to write or to ratify.

And yet that is precisely the reading the government proposes when it insists that a court may empower the executive to exercise power that the legislature has considered yet declined to allow.
It is a reading that thoroughly undermines both the legislature's own prerogative to reject a legislative proposal effectively and efficiently (without the need to affirmatively ban the proposed authority) and the more general protection against tyranny that the Founders believed required the careful separation of governmental powers."

"it is arguable that CALEA explicitly absolves a company like Apple of any responsibility to provide the assistance the government seeks here and also" "even if CALEA does not have such an explicit prohibition, it is part of a larger legislative scheme that is so comprehensive as to imply a prohibition against imposing requirements on private entities such as Apple that the statute does not affirmatively prescribe."

"The Justice Department is "disappointed" in Orenstein's ruling and plans to ask a higher judge within the same federal district to review the matter in coming days, a department representative said."
