Dissenting today in Christian Legal Society v. Martinez, Justice Samuel Alito put his finger on the majority’s underlying principle: there shall be “no freedom for expression that offends prevailing standards of political correctness in our country’s institutions of higher learning.” That pretty much says it all.

This case arose after the Hastings College of Law, a large public law school in San Francisco, denied the school’s tiny Christian Legal Society the same recognition and support it granted to some 60 other student organizations on the ground that CLS, contrary to the Hastings nondiscrimination policy, discriminates by requiring that its members and officers abide by certain key tenets of the Christian faith. In a word, in the name of anti-discrimination, Hastings, a government institution, discriminated against CLS, which was simply exercising its speech, religious, and associational rights. Cato filed an amicus brief in the case, written by the University of Chicago’s Richard A. Epstein, supporting the CLS students’ right to freedom of association.

But it was not to be. Justice Ruth Bader Ginsburg, writing for the Court’s three other liberals plus Justice Anthony Kennedy, held that the school’s “all comers” policy, which requires that student organizations accept anyone as members and even as officers, is “constitutionally reasonable,” taking into account all of the surrounding circumstances. That is a new standard for constitutionality when it comes to fundamental rights. And if students, whatever their interests or values, cannot form organizations limited to people who share those interests and values, what’s the point of having student organizations at all? In a word, like the mugger who says “Your money or your life,” today’s opinion enables Hastings to say, “If you want benefits otherwise available to all, you’ve got to give up your right to freedom of association.” No public institution should be able to put people to such a choice.
