Even before the Justices have decided whether to hear a case, the U.S. Chamber of Commerce is willing to step in and state its interest—more willing, in fact, than any other organization.
A review of certiorari-stage amicus curiae briefs (i.e., amicus briefs filed at the petition stage, before the Justices grant cert.) filed between May 19, 2004 and August 15, 2007 shows that the Chamber of Commerce filed 55 such briefs, about 17 per year. Over the three-and-a-quarter years studied, 986 parties filed cert.-stage amicus briefs, averaging 1.666 briefs per party. Of those 986 amici, 259 filed 2 or more, and 118 filed 3 or more. Not every party was included in the count, as we were most interested in the impact of private groups and advocacy organizations pushing cert. petitions; those excluded from the count are listed at the bottom of this post.
The top sixteen parties each filed 8 or more briefs, and a list of those groups, along with the success rates of the cases in which they filed (up to Tuesday's orders list), is
here. The success rate is calculated as a percentage of the party-supported petitions that were either granted or denied. (Note that only amicus briefs in support of a petition are considered here; the Washington Legal Foundation filed as an amicus in opposition to the petition in
Padilla v. Hanft (05-533) and was not counted in that instance.) Petitions supported by these top sixteen groups included many of the Court's most high-profile cases over the last few years, such as
US v. Booker,
MGM v. Grokster,
PICS v. Seattle Schools, and
Rumsfeld v. FAIR.
Notably, the list of top amici is dominated by pro-business and anti-regulatory groups—such groups hold over half the slots in the top sixteen. The prevalence of these groups may result from their having an enhanced financial ability to pay for many cert.-stage briefs as compared to other groups; the businesses and industries they comprise and represent may also be more eager to jump in at the petition stage when their bottom lines are at stake (as opposed to an ideological group); and it's possible, too, that these groups want to get as many cases as they can before a Supreme Court that is being increasingly viewed as business-friendly (e.g., see here). As a corollary, the absence of liberal or left-leaning groups is striking (with the National Association of Criminal Defense Lawyers as a narrowly-focused exception). The American Civil Liberties Union, for instance, tallied just two cert.-stage amicus briefs during this time.
A full quarter of the sweet sixteen are regionally-named legal foundations. Ranking third, fourth, seventh, and eighth overall in numbers of cert.-stage amicus briefs filed, the Washington Legal Foundation filed 26 briefs, the Pacific Legal Foundation filed 25, the New England Legal Foundation filed 11, and the Mountain States Legal Foundation filed 10. Their success rates were relatively high, ranging from about 18% (New England) to 39% (Washington). The Washington Legal Foundation, in fact, edged out the National Association of Home Builders (36%) to have the highest grant percentage of the top sixteen.
The only two groups in the top sixteen to be completely shut out were the Reporters Committee for Freedom of the Press (9 briefs in cases denied cert.) and the Society of Professional Journalists (8 briefs). Additionally, the Associated Press filed seven cert.-stage amicus briefs in cases that were all denied. These three groups, along with many other media organizations, often file amicus briefs together, so these are not 24 distinct denials, but rather just nine. Even so, since May 2004, these media groups hold the distinction of putting the most effort into pushing petitions while having no success.
