M. R. Evid. 403

The Court reviews a district court's ruling on whether to exclude evidence due to a danger of unfair prejudice for an abuse of discretion.  State v. Belanus, 2010 MT 204, ¶ 15, 357 Mont. 463, 240 P.3d 1021.  A district court abuses its discretion if it acts arbitrarily or exceeds the bounds of reason resulting in substantial injustice.  State v. Doyle, 2007 MT 125, ¶ 43, 337 Mont. 308, 160 P.3d 515.
