From what I've seen, Lincoln was acting in an interim capacity when Congress was out of session. When it was in session it passed laws that confirmed his suspension of habeas corpus. If Congress had disagreed with Lincoln and undone his action, its decision would surely have prevailed over his, and rightly so, though they were all duly-elected "representatives of the people." Just how representative of the people the Confederate Congress or Jefferson Davis was is also open to question. In any event, from the point of view of those who were detained, the fact of the suspension of the writ was more important than who initiated it. The most significant drawback in the article that was posted is that it ignores that the Confederacy applied the same tactics of control or oppression that it attacks Lincoln and the Unionists for employing.
As you probably know, Governor Hicks of Maryland was very supportive of the arrests, saying something to the effect that the problem was not the arrests, but the fact that the people arrested were later released.
It so comical that the neo-rebs show all this umbrage over these arrrests. The police chief of Baltimore was arrested. What an outrage! The fact that he helped blow up railroad bridges and was (after being released) a serving officer in the insurgent army doesn't mean a thing. The neo-rebs profess outrage just because the feds carried out the most fundamental duties of government.
One thing is clear, this police chief would not have donned the gray if he'd been hung as befitted a traitor. And it certainly bears repeating that dozens of loyal Union men were hanged in the so-called CSA having done nothing overt at all.
It's all more boo-hoo-hoo from the neo-rebs. "Mean old Lincoln kicked our butts!"
The fact is that President Lincoln's actions in Maryland, as so often, were masterful in concept and execution. The neo-rebs jut can't stand it because Lincoln outfoxed the traitors at every turn.

The Chief executive making legislative decisions is a bad idea - the Founders knew that.
Ex post facto legislation is unconstutional.
