unlike our last pResident.
Here's an excerpt of an excellent paper on this subject by Craig R. Smith:
Lincoln's assertion of power was not to go unchallenged. Less than a month after his suspension of the writ, a case began wending its way through the courts. The Merryman case was brought to bar to determine whether the President or the Congress had the power to suspend the writ of habeascorpus. It began on May 25, 1861, when John Merryman, a southern sympathizer and secessionist from Maryland, was taken into military custody. He immediately asked to be released under a writ of habeascorpus. In one of the oddities of history, the Chief Justice of the Supreme Court Roger B. Taney, a Democrat appointed by President Jackson, sat in judgment on the case as the circuit judge. Taney had penned the infamous Dred Scott decision of 1857 which Lincoln had consistently attacked. Now Taney and Lincoln crossed swords again.
In arguing for the President's power to suspend the writ, Attorney General Bates contended that the three great branches of the Government are coordinate; the executive cannot rightly be subjected to the judiciary. The President, he maintained, is in a peculiar manner their preserver and protector as the defender of the Constitution. (13) Moreover, it is the President's duty to put down a rebellion because the courts are too weak to do so. Bates pointed out that the power of the Presidency does open the way for possible abuse; however, it is just as true that a legislature may be factious or a court corrupt. The President cannot be required to appear before a judge to answer for his official acts because the court would be usurping the authority of Executive Branch. (14) Bates contended that for any breach of trust the President is answerable before the high court of impeachment and no other tribunal.
In filing his opinion, Taney responded that the President had no lawful power to issue such an order and that a writ of habeascorpus should preside. In Ex parte Merryman Taney claimed that only Congress could suspend the privilege of the writ and that the President, though sworn to "take care that the laws be faithfully executed," had broken the laws himself. In a clever rhetorical ploy, Taney used a hermeneutic argument invoking the rule of construction according to context. He pointed out that the provision regarding habeascorpus appears in that portion of the Constitution which pertains to legislative powers; therefore, its suspension was a legislative, not executive prerogative. Taney argued further that the military authorities should reveal the day and cause of the capture of Merryman and explain the reasons for his detention of Merryman. (15) Such requirements were, of course, usual in civil affairs, but not in military ones.
In a message to Congress on July 4, 1861, Lincoln answered Taney. He began by pointing out that he was reluctant to suspend the writ, but that dire threats to the nation in general and the military in particular required such action:
