Among many establishment clause matters over the years, Kramer Levin represented the American Federation of Teachers in litigation challenging the constitutionality of school voucher programs, from the Ohio trial court to the Ohio Supreme Court to the Sixth Circuit to the U.S. Supreme Court. Kramer Levin also has filed numerous amicus briefs on church/state issues on behalf of a range of civil rights/civil liberties organizations, including most recently in the Supreme Court urging affirmance of a decision that prayer before a local town meeting was unconstitutional coercion or endorsement of religion, in the Seventh Circuit supporting affirmance of a district court decision striking down the National Day of Prayer statute as crossing the line between permitted acknowledgment of religion and unconstitutional support for and exhortation of a religious practice, and in the Eleventh Circuit challenging the placement of an evolution disclaimer sticker in high school science textbooks in the public schools of Cobb County, GA.
