Does the ability to make executive orders by a President just negate the whole law -making process?In theory, no. In practice, no President has tested exactly how far he can go.
I mean, if it does, why do we even pretend that we have a democracy and a legislative process?*shrug* keeps the proles in line? Remember, at one point we only voted for 1/2 of 1/3 of the government.
More seriously, it's not Congress's job to work out every last detail of implementation. That's why we have a three-branch system and not a parliament. Congress sets broad policies and allocates resources, then the executive branch actually implements it. Also, keep in mind that not just the President can issue an executive order, he may delegate that authority to a cabinet official or even lower conceivably.
Executive orders do
not inherently have force of law, however, many Congressional acts specifically authorize that an executive order issued in the implementation of the law will have the force of law.
Are executive orders secret? Where are they published?A) No, they are public.
B) They are published generally at
http://www.archives.gov/federal-register/executive-orders/disposition.html in the Federal Register of the National Archives
What happens if an executive order contravenes established law? Does anyone anywhere anytime examine executive orders for their legality/Constitutionality? What is the review process if any for executive orders?If an executive order has been given color of law by Congressional authorization, it is equally subject to judicial review as if it had been part of the law. If Congress has not authorized that status (ie, the order is just an administrative directive for the department in question) there's very little that can be done outside of the political process (unless something in the order blatantly disregards existing law, in which case that law can be used as grounds for a suit just like in any other action by that department).
Are successive executives able to overturn the executive orders of their predecessors at will?Yes.
