As noted below, 44 law professors have filed a brief in the Obamacare abortion/contraception mandate case claiming that corporate law does not support allowing companies to exercise religion or to vindicate the rights of their shareholders seeking to exercise their religious beliefs. Their brief is a paean to the merits of corporate personhood. From page 5, for example:
Indeed, this legal separateness—sometimes called legal “personhood”—has been the very basis of corporate law at least since the 18th Century.
Since many (most) of these professors are social liberals (I suppose that went without saying), I'd be willing to bet that at least some of them have had some rather nasty things to say about corporate personhood in connection with Citizens United or other cases in which corporate personhood gored the liberal ox. If I had the time and energy, it would be interesting to run that hypothesis down. But I don't. Which is just one more reason I need minions to do this sort of thing.
But if you're on the side of the angels on this issue and have interns with time on their hands, why not turn them loose on the question.
