The Catholic Bishops in the Rehnquist Court: Track Record as Amicus Curiae

By my count, the United States Conference of Catholic Bishops filed amicus curiae briefs in 22 cases during the Rehnquist Court. (For a spreadsheet showing USCCB amicus briefs and Justices’ votes for OT86-OT10, see here. Please let me know if the spreadsheet contains any errors.) Ten of the briefs dealt with religious liberty (encompassing statutory, Free Exercise, and Establishment Clause cases); six addressed abortion; three were about end-of-life issues; two involved the death penalty; and one addressed associational freedom. The chart below provides for crude comparisons among the Justices, placing them in an array of more or less agreement in their votes for the party (petitioner or respondent) supported by the USCCB’s amicus curiae briefs. Direct comparisons cannot be made among all the Justices due to the changing composition of the Court over this time period.

The point of counting votes in this particular way is not to assess the influence of the Bishops’ Conference. It is highly doubtful that the Conference’s presence or absence as amicus curiae has had any effect on how the Justices voted. The point, instead, is to define the universe of cases in which the Bishops have an interest in the outcome and to see how hospitable various Justices have been to the claims advanced by the parties supported by the Bishops’ Conference amicus curiae briefs.

Justice Brennan and Justice White from the Catholic Bishops’ Point of View

During his time on the Rehnquist Court, Justice Brennan voted in seven cases in which the United States Conference of Catholic Bishops (the “USCCB” or “Bishops’ Conference”) filed an amicus curiae brief. He voted for the party supported by the Bishops’ Conference in three out of those seven cases. By contrast, during his time on the Rehnquist Court, Justice White voted in ten cases in which the USCCB filed an amicus curiae brief (the same seven as Justice Brennan, plus three more). He voted for the party support by the Bishops’ Conference in all ten of those cases.

The low level of agreement between Justice Brennan and the Bishops’ Conference is notable given that Justice Brennan was the last beneficiary of a so-called “Catholic seat” on the Supreme Court.  And Justice Brennan’s voting pattern presents an interesting contrast with Justice White’s.  The contrast is noteworthy because President Kennedy appointed White. As the country’s first (and thus far only) Catholic President, Kennedy could not politically afford to nominate a Catholic to the Supreme Court.  By contrast, Brennan’s Catholicism was an important factor in making him an attractive nominee for Eisenhower.  Thus, one reason that Brennan was appointed is that he was a Catholic, while one reason White was appointed is that he was not a Catholic.  Yet White ended up consistently voting with the Catholic bishops on the Rehnquist Court, while Justice Brennan had one of the lowest rates of agreement during the same time period.

There were five other Justices who voted in all ten cases in which the Bishops’ Conference filed an amicus curiae brief and in which Justice White voted: Chief Justice Rehnquist, Justice Blackmun, Justice Stevens, Justice O’Connor, and Justice Scalia. Rehnquist and Scalia joined White in voting for the party supported by the Bishops’ Conference in all ten of these cases. Justice O’Connor voted for that party in eight out of those ten cases, Justice Stevens in three, and Justice Blackmun in two. In the first several years of the Rehnquist Court, then, the three Justices with the best track record from the point of view of the Bishops’ Conference consisted of two Protestants (Chief Justice Rehnquist and Justice White) and one Catholic (Justice Scalia).
