Kratovil v. Liberty Northwest Ins. Corp. [09/07/07] 2007 MTWCC 38 While Mont.R.Civ.P. 8( c) provides that a statute of limitations defense must be pled as an affirmative defense, ARM 24.5.302(1)(a) requires a respondent to set out its contentions in its response, and therefore the Court will not consider a statute of limitations defense if it is not listed in the contentions.
