“The Constitution provides that Congress shall make laws, the President execute laws, and courts interpret laws. It did not provide for government by injunction in which the courts and the Executive Branch can “make law” without regard to the action of Congress. It may be more convenient for the Executive Branch if it need only convince a judge to prohibit conduct rather than ask the Congress to pass a law, and it may be more convenient to enforce a contempt order than to seek a criminal conviction in a jury trial. Moreover, it may be considered politically wise to get a court to share the responsibility for arresting those who the Executive Branch has probable cause to believe are violating the law. But convenience and political considerations of the moment do not justify a basic departure from the principles of our system of government.”

Comment: This could be read as a rebuke of the Imperial Presidency in general, and the Obama Administration specifically.
