Obama suspends the law. What would Lincoln say?

Scholars have debated whether Lincoln exceeded his power by suspending the writ and whether Congress’s retroactive ratification cured any constitutional infirmity. Whatever one’s answer, this is a case of a president—himself a constitutional lawyer—trying, under impossible circumstances, to be as faithful to the Constitution as possible.

Contrast all of this with President Obama’s announcement that he is unilaterally suspending part of the Affordable Care Act. Like Lincoln, Mr. Obama is a constitutional lawyer. And like Lincoln’s action, Mr. Obama’s was a unilateral executive suspension of the law. But in every other way, the president’s behavior could not have been more different from Lincoln’s.

First, Lincoln’s action was at least arguably constitutional, while Mr. Obama’s is not. The Constitution has a provision for suspending habeas. It has no general provision for executive suspension of laws. English kings used to suspend laws, but the Framers rejected that practice: The president “shall take Care that the Laws be faithfully executed.”

Second, Lincoln volunteered an articulate constitutional defense of his action. Mr. Obama seemed annoyed when the New York Times dared to ask him the constitutional question. When the reporter asked whether he had consulted with lawyers about the legality of the mandate’s delay, he declined to answer.
