This historic week of Supreme Court arguments won’t be the first time that two of the main antagonists, Donald Verrilli Jr. and Paul Clement, have gone head to head before the justices over health care.

It happened once before, in Novem­ber 2003 — one of two occasions when the now-veteran advocates opposed each other before the Court. Both times, Verrilli won. (In a third case, they were on the same side — the winning side. See charts below.)
