As told in a guest post at Balkinization by Michael Stokes Paulsen:

I was, quite literally, teaching *Stenberg* v. Carhart (following on the heels of Monday's class on Roe v. Wade and Tuesday's on Planned Parenthood v. Casey), when a student broke in with the comment that the Court had decided today's partial-birth abortion case, upholding the federal statute. (Ah, the joys of internet access in the classroom.) Seamlessly weaving the student's interjection into the class decision, I asked him about the holding: "Who wrote?" (No one needed to ask the vote or the lineup.) "Kennedy?! Makes sense. Was Stenberg overruled? Could he do that, consistent with his opinion in Casey?"

As you might expect, there's lots of interesting blogging about Carhart at Balkinization; just keep scrolling.
