Then that could be appealed, also unless it's the USSC.
Oh for sure, and we can hope so. I'm not even sure if Sebelius asked for severability; Hudson may have just done it on his own. Both the 4th Circuit and the USSC can take or leave any part of Hudson's decision, and add whatever they want, assuming it's upheld.
The reason I'm holding out some hope for Souter is that the aggregation of inactivity--it's bad enough that
Wickard gave us "aggregation" of
intrastate activity at all--lacks
any logical limit. The inacivity argument could be applied to aggregate the failure to purchase
anything. I suspect that the pure illogic of this may offend Souter's generally theorem-based reasoning.
