Okla. Stat. tit. 63, § 3090.4

A cause of action for injunctive relief may be maintained against any health care provider who is reasonably believed to be about to violate, who is in the course of violating, or who has violated the Nondiscrimination in Treatment Act by an affected patient or a person legally authorized to make health care decisions for the patient. However, a violation of the act does not constitute negligence per se for purposes of a civil action for damages.
