951.015 951.015 Construction and application.
951.015(1)(1)This chapter may not be interpreted as controverting any law regulating wild animals that are subject to regulation under ch. 169, the taking of wild animals, as defined in s. 29.001 (90), or the slaughter of animals by persons acting under state or federal law.

951.015 Annotation Rather than exclude all non-captive wild animals from coverage of ch. 951, the legislature instead prohibits enforcement that controverts ch. 29 and regulations governing “the taking of wild animals." By prohibiting a subset of takings — those that controvert ch. 29 — the legislature necessarily conveys its belief that there are takings that do not controvert ch. 29. State v. Kuenzi, 2011 WI App 30, 332 Wis. 2d 297, 796 N.W.2d 222, 09-1827.
