Nor is the one-year delay of the employer mandate an affront to the Constitution, as Professor Michael McConnell and Congressional Republicans insist. The relevant text requires that the President "take care that the laws be faithfully executed." Scholars on both left and right concur that this broadly-worded phrasing indicates that the President is to exercise judgment, and handle his enforcement duties with fidelity to all laws, including, indeed, the Constitution. As McConnell himself notes, both Republican and Democratic Justice Departments have consistently opined that the clause authorizes a president even to decline enforcement of a statute altogether, if in good faith he determines it to be in violation of the Constitution. But, McConnell contends, a president cannot "refuse to enforce a statute he opposes for policy reasons." While surely correct, that contention is beside the point.
The Administration has not postponed the employer mandate out of policy opposition to the ACA, nor to the specific provision itself. Thus, it's misleading to characterize the action as a "refusal to enforce." Rather, the President has authorized a minor temporary course correction regarding individual ACA provisions, necessary in his Administration's judgment to faithfully execute the overall statute, other related laws, and the purposes of the ACA's framers. As a legal as well as a practical matter, that's well within his job description.
