Can we or someone sue to have them ruled unconstitutional? I’m not a lawyer, so I have not idea who could bring a challenge, but surely someone can.... and should.
Congress may have standing since any Executive position exercising policy level decisions must be nominated to the Senate for confirmation.
Oh, I forgot to mention I think Obama’s administration has classified these czars as “Presidential advisors” in order to slip them past confirmation requirements.
Advisors however do not exercise any executive power, thus if any of these czars directly exercise any executive powers their decisions and orders may be refused as unconstitutional, although in all likelihood you’ll find yourself fired long before this makes it into a court room.
I guess that means that if one of these czars issues an order anybody affected by that order may have standing to sue the administration over the constitutionality of the order.
