I am aware of Art III Sec 2, but not of the clause in the MCA. Since you obviously read much on the subject, do you know if and how the dissenters referenced the MCA clause?
If the majority clearly ignored its lack of jurisdiction, then we have a lot more than run of the mill liberal abuse of power, we have no sh!t impeachable offenses.
If I read the decision correctly the court held that the Constitution’s provision for suspending habeas takes precedence over the MCA or the DTA and that congress did not properly suspend habeas corpus because the conditions today don’t meet the justifications in the Constitution. And since the Court have assumed the role of final arbitrator for what is constitutional Article III Section 2 did not come up.
