In a wide-ranging 128-page complaint, a woman who alleges that her medical conditions make it dangerous for her to wear a face mask filed suit in an Indiana federal district court earlier this month against 16 separate defendants challenging the legality of COVID- related mandates or recommendations to wear cloth face masks.

421. Wearing talismans and other pagan, non-medical masks is against Plaintiff's religious beliefs.
422. Mandating everyone wear non-medical masks to prevent disease when the mask manufacturers cannot make claims they prevent disease transmission is the same as the State establishing a religion in which the Mask Deity prevents its wearers from becoming infected with disease.
423. The State cannot mandate the Plaintiff follows its religion. Plaintiff has the right to freely exercise her religion according to the dictates of her own conscience.
