And, irrelevant. USSC justices aren't expected to recuse from cases on the basis of their own political affiliations, let alone their spouse's.
No, you asked should he have known. He clearly knows what she does. It isn’t about her political affiliation but her lobbying for something that he might be involved with at some point.
Again, perception. I’m not saying he did anything wrong. By the books it looks like he hasn’t.But given this revelation and being the ONLY Justice to dissent it looks bad.
Look at te WE scandal. Morneau’s daughter working for WE and the PMs wife getting travel and per diems paid for to speak. And they get the contract. By your logic, there’s nothing to see there because Morneau and Trudeau could just claim they aren’t involved in what their family members do. I realise it’s not the same but the issue is perception.
USSC justices usually and historically recuse themselves when financial interests are involved. Some have recused themselves over personal issue such as knowing a victim or sometimes when it involved someone who voted not to confirm them.
It seems though as I look at it that the rules for USSC justices are far less stringent than that of federal court ones and the decision to refuse is ultimately up to the Justice.
