I agree csmsss.
It should be understood that this was going to be appealed, regardless of who won. However... There is currently a bill before the MD legislature that would make MD a "shall issue" state and if passed (and signed into law), would moot any further action in the courts.
However unlikely this might have been before this decision, it now requires its legislatures to rethink their positions. They can kill the proposed bill and take their chances in the Circuit Court. That can be real risky at this time, because a decision there will affect more than just MD. Then there is the SCOTUS to consider....
Think chess, not checkers.
