The state Court of Appeals has granted James Arthur Ray's request to drop his challenge of the case, and also dismissed a cross-appeal.
Ray says he wanted to avoid the possibility of a retrial and resentencing. He maintains that his convictions on three counts of negligent homicide were flawed, but the state Attorney General's Office disputed that.
Dozens of people participated in Ray's sweat lodge ceremony near Sedona in October 2009. The three who died were Kirby Brown of Westtown, N.Y.; James Shore of Milwaukee; and Liz Neuman of Prior Lake, Minn.
Ray remains in Arizona on community supervision. He'll be allowed to leave the state next month.
