The Supreme Court on Monday appeared sympathetic to the argument by a Catholic Charities chapter that Wisconsin violated the Constitution when it refused to give the group the same exemption from the state’s unemployment tax that it provides to churches, religious schools, and some religious groups. Justices from both sides of the ideological spectrum seemed to agree that the state’s denial of the exemption amounted to discrimination against Catholic Charities, with Justice Elena Kagan suggesting that it was “pretty fundamental that we don’t treat some religions better than others. And we certainly don’t do it based on the content of the religious doctrine that those religions preach.”
