We have reviewed the underlying facts, which are not in dispute, and the extensive discussion and analysis of principles of collateral estoppel applicable thereto as made in the opinion of the Honorable Elsijane T. Roy, District Judge. We affirm the order dismissing the indictment on the basis of Judge Roy's well-reasoned opinion, reported at 517 F. Supp. 1214 (E.D.Ark. 1981). See Ashe v. Swenson, 397 U.S. 436, 90 S.Ct. 1189, 25 L.Ed.2d 469 (1970).
