Justice Brennan Jr. wrote the 5-4 majority opinion. The Court ruled that the 50% funding rule unfairly treated different religious groups differently and showed favoritism among them, which the government is prohibited from doing. "The clearest command of the Establishment Clause," according to the Court, "is that one religious denomination cannot be officially preferred over another." The Court also found that the Minnesota law failed the three-part test from
Lemon v. Kurtzman because it encourages government involvement in religious matters. Justice Stevens filed a concurring opinion. Justice White dissented, arguing that the majority mistakenly applied a different legal approach than the previous courts and should have remanded instead. He also believed the majority was wrong to dismiss Minnesota’s argument that it had a valid, non-religious reason for the law—protecting the public from fraudulent charities. Justice Rehnquist joined in the dissent. Justice Rehnquist wrote a separate dissent, arguing that the registration requirement applies to the Unification Church because it is a charitable organization, not because it is or isn’t a religious group under the 50% rule. As it’s not clear whether the church qualifies as a religious organization under the law, he argued the Court should not have decided the constitutional issue. Chief Justice Burger, Justice White, and Justice O’Connor joined in the dissent. == Impact ==
