"Fifteen individual or collective “friends of the court”—amici curiae—filed briefs in Roe v. Wade, eight for the challengers to the Texas law and seven in the state’s defense. (Several on both sides also filed supplemental briefs for the second argument.) This was a substantial number for the time, although it looks small by the standards of today, when even in cases of only moderate importance, the Court often receives two dozen briefs or more."
