A motion asserting any of these defenses must be made before pleading if a responsive pleading is allowed. If a pleading sets out a claim for relief that does not require a responsive pleading, an opposing party may assert at trial any defense to that claim. No defense or objection is waived by joining it with one or more other defenses or objections in a responsive pleading or in a motion.
Nev. R. Civ. P. 12
Advisory Committee Note 2019 Amendment
The Committee considered but rejected the suggestion that improper venue be added to Rule 12(b) to track FRCP 12(b)(3). As explained in the advisory committee note to Rule 12 of the 1953 NRCP, "The federal defense of improper venue is deleted, since improper venue is not a defense under state practice, but is a ground for change of venue. Practice as to change of venue will not be affected by this rule. Motion therefor may be made, or will be waived, apart from the requirements of Rule 12(h)." See NRS Chapter 13, in particular, NRS 13.050, which requires the demand for change of venue be made "before the time for answer expires."
Rule 12(b)(5) mirrors FRCP 12(b)(6). Incorporating the text of the federal rule does not signal an intent to change existing Nevada pleading standards.
