Thorpe v. Mahin

This is an original taxpayers’ action filed pursuant to leave of this court for a declaratory judgment that the Illinois Income Tax Act, (Public Act 76 — 261, Laws 1969, approved July 1, 1969,) is invalid and seeking writs of injunction to restrain the authorities from collecting any tax under the Act and from expending any moneys for that purpose. The cause is submitted on petition, supplement to petition and the answer of the defendant State officials. In addition, we have permitted the filing of certain amicus curiae briefs. There is no question of fact involved.
