Michael McConnell, writing at the Wall Street Journal, notes:
President Obama's decision last week to suspend the employer mandate of the Affordable Care Act may be welcome relief to businesses affected by this provision, but it raises grave concerns about his understanding of the role of the executive in our system of government.Of course, it not just ObamaCare. McConnell points out that Obama (or some other future president) could refuse to enforce or carry out restrictions on immigration or taxes. He notes, however, that, based on Supreme Court precedent, it is likely that no one will have legal standing to bring a suit to require the President to enforce the laws he doesn't like. McConnell concludes:
Article II, Section 3, of the Constitution states that the president "shall take Care that the Laws be faithfully executed." This is a duty, not a discretionary power. While the president does have substantial discretion about how to enforce a law, he has no discretion about whether to do so.
This matter—the limits of executive power—has deep historical roots. During the period of royal absolutism, English monarchs asserted a right to dispense with parliamentary statutes they disliked. King James II's use of the prerogative was a key grievance that lead to the Glorious Revolution of 1688. The very first provision of the English Bill of Rights of 1689—the most important precursor to the U.S. Constitution—declared that "the pretended power of suspending of laws, or the execution of laws, by regal authority, without consent of parliament, is illegal."
To make sure that American presidents could not resurrect a similar prerogative, the Framers of the Constitution made the faithful enforcement of the law a constitutional duty.
Of all the stretches of executive power Americans have seen in the past few years, the president's unilateral suspension of statutes may have the most disturbing long-term effects. As the Supreme Court said long ago (Kendall v. United States, 1838), allowing the president to refuse to enforce statutes passed by Congress "would be clothing the president with a power to control the legislation of congress, and paralyze the administration of justice."
