I enjoy reading the little paragraph at the end of a Supreme Court decision syllabus summarizing who voted with whom. They tell you how complicated any particular court decision is.

Here are some examples, from simplest to most complicated.

First, there’s the per curiam opinion, which is unsigned, and therefore needs no summary at the bottom of the syllabus telling who voted with whom:

There’s the unanimous opinion:

SOUTER, J., delivered the opinion for a unanimous Court.

Then there’s the case with a lone dissenter or concurrer:

SCALIA, J., delivered the opinion of the Court, in which ROBERTS, C. J., and STEVENS, KENNEDY, SOUTER, GINSBURG, BREYER, and ALITO, JJ., joined. THOMAS, J., filed a dissenting opinion.

There’s the case with a few dissenters signing one opinion:

KENNEDY, J., delivered the opinion of the Court, in which ROBERTS, C. J., and SCALIA, THOMAS, and ALITO, JJ., joined. BREYER, J., filed a dissenting opinion, in which STEVENS, SOUTER, and GINSBURG, JJ., joined.

There’s the case with a partial concurrence or dissent:

SOUTER, J., delivered the opinion of the Court, in which ROBERTS, C. J., and SCALIA, KENNEDY, THOMAS, BREYER, and ALITO, JJ., joined. STEVENS, J., filed a dissenting opinion, in which GINSBURG, J., joined, except as to Part IV.

There’s the case with both a concurrence and a dissent:

SCALIA, J., delivered the opinion of the Court, in which ROBERTS, C. J., and KENNEDY, SOUTER, THOMAS, GINSBURG, and ALITO, JJ., joined. KENNEDY, J., filed a concurring opinion, in which ALITO, J., joined. BREYER, J., filed a dissenting opinion, in which STEVENS, J., joined.

There’s the case with multiple concurrences and/or dissents:

ALITO, J., announced the judgment of the Court and delivered an opinion, in which ROBERTS, C. J., and KENNEDY, J., joined. KENNEDY, J., filed a concurring opinion. SCALIA, J., filed an opinion concurring in the judgment, in which THOMAS, J., joined. SOUTER, J., filed a dissenting opinion, in which STEVENS, GINSBURG, and BREYER, JJ., joined.

There’s the case where it gets a little more complicated:

SOUTER, J., delivered the opinion of the Court, in which ROBERTS, C. J., and SCALIA, KENNEDY, THOMAS, BREYER, and ALITO, JJ., joined, and in which STEVENS and GINSBURG, JJ., joined as to Part III. THOMAS, J., filed a concurring opinion, in which SCALIA, J., joined. GINSBURG, J., filed an opinion concurring in part and dissenting in part, in which STEVENS, J., joined.

Or even more complicated:

ROBERTS, C. J., announced the judgment of the Court and delivered the opinion of the Court with respect to Parts I, II, III–A, and III–C, in which SCALIA, KENNEDY, THOMAS, and ALITO, JJ., joined, and an opinion with respect to Parts III–B and IV, in which SCALIA, THOMAS, and ALITO, JJ., joined. THOMAS, J., filed a concurring opinion. KENNEDY, J., filed an opinion concurring in part and concurring in the judgment. STEVENS, J., filed a dissenting opinion. BREYER, J., filed a dissenting opinion, in which STEVENS, SOUTER, and GINSBURG, JJ., joined.

But I think my favorite is this one, from a 2003 campaign finance decision (which, incidentally, was gutted last week):

STEVENS and O’CONNOR, JJ., delivered the opinion of the Court with respect to BCRA Titles I and II, in which SOUTER, GINSBURG, and BREYER, JJ., joined. REHNQUIST, C. J., delivered the opinion of the Court with respect to BCRA Titles III and IV, in which O’CONNOR, SCALIA, KENNEDY, and SOUTER, JJ., joined, in which STEVENS, GINSBURG, and BREYER, JJ., joined except with respect to BCRA §305, and in which THOMAS, J., joined with respect to BCRA §§304, 305, 307, 316, 319, and 403(b). BREYER, J., delivered the opinion of the Court with respect to BCRA Title V, in which STEVENS, O’CONNOR, SOUTER, and GINSBURG, JJ., joined. SCALIA, J., filed an opinion concurring with respect to BCRA Titles III and IV, dissenting with respect to BCRA Titles I and V, and concurring in the judgment in part and dissenting in part with respect to BCRA Title II. THOMAS, J., filed an opinion concurring with respect to BCRA Titles III and IV, except for BCRA §§311 and 318, concurring in the result with respect to BCRA §318, concurring in the judgment in part and dissenting in part with respect to BCRA Title II, and dissenting with respect to BCRA Titles I, V, and §311, in which opinion SCALIA, J., joined as to Parts I, II—A, and II—B. KENNEDY, J., filed an opinion concurring in the judgment in part and dissenting in part with respect to BCRA Titles I and II, in which REHNQUIST, C. J., joined, in which SCALIA, J., joined except to the extent the opinion upholds new FECA §323(e) and BCRA §202, and in which THOMAS, J., joined with respect to BCRA §213. REHNQUIST, C. J., filed an opinion dissenting with respect to BCRA Titles I and V, in which SCALIA and KENNEDY, JJ., joined. STEVENS, J., filed an opinion dissenting with respect to BCRA §305, in which GINSBURG and BREYER, JJ., joined.

So much for judges being mere umpires!
