Oath of office of the President of the United States, “I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.”
Doesn’t this oath require the president to uphold all the laws and regulations that have been passed by the Congress and signed by the president that held office? If that isn’t the expectation of all of our presidents then why do we have the three parts of government? Those three are legislative, executive, and judiciary. It has been accepted practice that the judiciary branch of government, in the form of the Supreme Court, is the final authority on the legality of any law.
Does the Department of Justice Have an Obligation to Defend the Defense of Marriage Law? If you accept the above method of our system of governance then the answer must be YES!
Without a process we have no system of justice.
