En banc? I suppose they could, and it’s a question of significant enough importance, but I rather doubt it. I think this more likely to go to the SCOTUS.
I just checked and the 11th circuit has 10 active judges, split 5-5 among D and R appointments. They’d need at least 6 votes to overturn the panel, so it would seem unlikely. Moreover, one of the Clinton judges, Hull, was part of today’s majority, so the scales are tilted even more against an overrule.
With the split between here and the 6th circuit, plus the VA case, we know this is going to end up at the SC. Why waste time on en banc.
Just get it done with at the top.
