PER CURIAM:
We find that these consolidated cases require a three-judge district court, 28 U.S.C. § 2281. We therefore vacate the decision of the lower court, 346 F.Supp. 913, for want of jurisdiction and remand the cases with instructions to convene a three-judge district court pursuant to 28 U.S.C. § 2284. Vacated and remanded.
