Brent Fletcher, an employee of UP&L, was responsible fo rcontracting and management of security services for UP&L frm 1976 to 1984. During that time, defendants Michael Wall, Bruce Conklin and Michael Ziermski created a shell company that provided Fletcher with bribes in order to win security contracts. IN the Thompson case, the Utah Court of Appeals ruled that under the Utah Antitrust Act, a vertical boycott was a per se criminal violation. The case was reversed on appeal to the Utah Supreme Court on other grounds, 810 P.2d 415 (Utah 1991).
