Freedom of exercise clause?

U.S. Solicitor General Donald Verrilli told the Supreme Court on Tuesday that the First Amendment right to the free exercise of religion and the Religious Freedom Restoration Act (RFRA)—which Congress enacted to guide the Executive Branch and courts in defending that right—would not directly protect kosher or halal meat-processing corporations from a hypothetical federal rule that by generally banning certain meat-processing practices effectively banned kosher and halal meat processing by incorporated businesses.
Verrilli told the court that the customers of a kosher or halal meat-processing company–not the company itself–would have cause to sue in such a situation.
