The standard of review of a trial court's discretionary ruling is for abuse of discretion. Mont. Rail Link v. Byard, 260 Mont. 331, 337, 860 P.2d 121, 125 (1993). This standard may be applied to rulings on post-trial motions, which "encompass the power of choice among several courses of action, each of which is considered permissible." Steer, Inc. v. Dep't of Revenue, 245 Mont. 470, 474, 803 P.2d 601, 603 (citations omitted) (1990); see also Johnson v. Hamilton, 2003 MT 199, ΒΆ 9, 317 Mont. 24, 27, 75 P.3d 778, 780.
