See Iowa Code § 86.40. I would defer, as this court routinely does, to the commissioner's interpretation of agency rules. See, e.g., Neal v. Annett Holdings, Inc., 814 N.W.2d 512, 518 (Iowa 2012) ; Boehme v. Fareway Stores, Inc., 762 N.W.2d 142, 146 (Iowa 2009) ; see also John Deere Dubuque Works v. Caven, 804 N.W.2d 297, 300–01 (Iowa Ct.App.2011) ; cf. Franich v. Real Estate Comm'n, 681 N.W.2d 620, 623 (Iowa 2004) (“[W]e give ‘appropriate deference’ to the view of the Commission with respect to the interpretation of ... the rules adopted pursuant to the authority granted in [chapter 543B].”). The legislature has granted the workers' compensation commissioner authority to make and enforce “rules necessary to implement [the workers' compensation statutes].”
