Appellants seek review by this Court of the refusal by the District Court to convene a three-judge District Court pursuant to 28 U. S. C. §§ 2281-2284. We have held that such review is available in the Court of Appeals, Idlewild Bon Voyage Liquor Corp. v. Epstein, 370 U. S. 713, and not in this Court. Buchanan v. Rhodes, 385 U. S. 3.

The motion to dismiss is granted and the appeal is dismissed for lack of jurisdiction.
