State ex rel. Deborah Howenstine, M.D. v. The Honorable Ellen S. Roper

Summary

The Supreme Court of Missouri held that Dr. Deborah Howenstine was protected from a medical malpractice suit by both official immunity and public duty immunity. The court concluded that her duties as medical director of a public health clinic involved discretionary governmental functions and duties owed to the public, not specifically to the plaintiff. The court made its preliminary writ of prohibition absolute.

Holdings

1. Prohibition was appropriate because the material facts were undisputed and the trial court's denial of summary judgment wrongly deprived Dr. Howenstine of absolute immunity as a matter of law.
2. Dr. Howenstine was protected by official immunity because she was a public official acting in a discretionary capacity as medical director of the public health clinic.
3. The treating-physician exception did not apply because Muren did not allege negligent treatment by Dr. Howenstine herself, and the nurses' tuberculosis treatment was performed under independent statutory authority and written protocols rather than under her medical license.
4. The applicable population-based public-health regulation did not impose on Dr. Howenstine a specific nondiscretionary duty to ensure the nurses' competency or oversee their tuberculosis services. Any duty beyond the regulation was discretionary and protected by official immunity.
5. Dr. Howenstine was protected by public duty immunity because, in her role as medical director, she owed duties concerning the clinic's population-based tuberculosis services to the public generally, not to Muren individually.

Questions Presented

1. Whether prohibition was an appropriate remedy to address the trial court's denial of summary judgment on absolute immunity grounds.
2. Whether Dr. Howenstine, acting as medical director of a public health clinic, was a public official performing discretionary functions protected by official immunity.
3. Whether the nurses' tuberculosis treatment was performed under independent statutory and regulatory authority rather than under Dr. Howenstine's medical license, defeating vicarious-liability arguments based on the treating-physician exception.
4. Whether Missouri's collaborative-practice regulations imposed on Dr. Howenstine a nondiscretionary duty to ensure the nurses' competency or to oversee the clinic's population-based tuberculosis services.
5. Whether Dr. Howenstine was protected by public duty immunity because her medical-director duties were owed to the public generally rather than to Muren individually.
