On what basis are they recused?

The same basis a fox judge should not be in charge of a court that rules on whether foxes should be legally able to eat chickens.

If you are implying that they are gay, what is your basis for making that claim? Roberts is married and has two children.

Is Scalia recused? He has publicly said that it is a "no brainer" to say that there is no constitutional right to gay marriage. So he has publicly pre-judged this case.

I expect no there will in fact be no recusals in this case.
