He brought his claim not under the ADA, but under a provision of the Indiana Code that prohibits an employer from requiring as a condition of employment that an employee implant, inject, ingest, inhale, or incorporate an acoustic, optical, mechanical, electronic, medical, or molecular device into their body. Muckenfuss claimed that the face mask qualified as a such a device, and that Tyson violated the statute by requiring that he wear it on his face.
The trial court had little difficulty in dismissing this claim.
This statute was aimed to prohibit the introduction of a device "into" the body. Wearing a mask on one's face isn't that.… Mr. Muckenfuss invites an interpretation that would render this statute absurd.… [H]is interpretation would suddenly prohibit all sorts of sensible mandates by employers. No longer could a company require a bleeding employee from wearing a bandage or band-aid "against" his wound. No longer could a company require an employee to wear a protective glove, or work boots, or goggles, or many types of personal protective equipment because they were likewise designed to be used "against" the body.
