NO, the Supreme Court has ruled it is constitutional.
Are the exemptions that have been given legal?
Only Congress can tax, and only Congress can declare exemptions.
Once SEIU realizes they are no longer exempt, they will not be for this just like the rest of us.
The Supreme Court did not rule on the issue of whether or not the Act is Unconstitutional because it did not originate in the House. That issue was not before the Court, nor did yesterday's opinion address it.
