If they had a history of overturning laws and making up reasons to rule in favor of religion because they're religious then yeah, I bet they were grilled. 
As in "hey, do you believe in an all powerful (but not really), super duper contradictory p being that created everything and everyone that you must obey, no matter what?"  "Or, have you studied philosophy, the development of religion and religious dogma and understand how mankind came to worship the deity of the day?"  If they answer "yes" to this one, they are acceptable.
