“They have cell phones as well...”
Similar to the VCR case in the 80’s where they found the retained home copy of broadcast TV to be “time-shifting” and allowed it - the majority of Justices had VCR’s.
Then the Blackberry case, essentially gutting injunctive relief for patent owners in many cases - but the Justices couldn’t take the chance their Blackberries stop working.
Bottom line - if a case really has broad implications and could actually affect the Justices personally, don’t be surprised if they find a way to write a decision in their own best interests.
This is why, if I was President, I'd throw them [the USSC] in indefinite detention
(with access to lawbooks/resources via a PFC) under the NDAA and their own ruling that indefinite detention is kosher… once their decisions start impacting them negatively, you can bet your ass they'll reverse it.
PS — I'd also love to see their personal property taken under Kelo-reasoning.
