>>Ladies and gentlemen, should an officer of the Armed Forces refuse to follow or implement any order or policy of the Congress or Courts that he considers to be unconstitutional?<<
Yes. Read the oath of office they take.
It is probable that Scotus will soon usurp Article I Sections 1 & 8, and make law. It will illegally take on the Congressional power to “make rules for the Government and Regulation of the land and naval forces;” and order the military to keep, enlist and commission open homosexuals.
Should the Supreme Court do this, should an officer comply with this unconstitutional diktat any more than comply with an order to deploy to Iraq?
