Supreme Judicial Court hears whether insurer must defend doctor in board complaint over alleged improper prescribing

The Supreme Judicial Court heard oral argument over whether MagMutual Insurance Company must defend Dr. William E. O'Connor in an administrative complaint to the Board of Registration in Medicine that alleges he prescribed medication to manipulate a patient's personal relationship.

Attorney Christopher Trundy, representing plaintiff‑appellant William O'Connor, told the court: "We are here asking you to reverse the determination of coverage, which was entered in the Superior Court, and we believe was in error, because the actual policy language very explicitly covers the nature of the insurance." Trundy emphasized that the policy contains a standalone regulatory‑defense provision to cover defenses in administrative investigations even where no malpractice claim for damages has been tendered.

The bench repeatedly pressed counsel on timing: "Can I ask a time question? So the policy is entered into in 2019, right?" Justice Kafker asked, noting the last medical treatment at issue occurred in 2016. Several justices questioned whether that temporal gap undercuts a causal link between the prescribing and later alleged misconduct.

MagMutual's attorney, Sean Ennis, framed the dispute around the duty to defend versus the duty to indemnify, telling the court the duty to defend "is broader than the duty to indemnify" but arguing that the four‑corners of the complaint must be compared to the policy language. Ennis said the complaint's gravamen centers on alleged stalking and related misconduct and that the paragraph about prescription use alleges an illegitimate purpose rather than ordinary medical treatment.

Justices explored whether an allegation that a doctor wrote prescriptions to "keep her in an existing relationship" constitutes a professional medical service covered by the regulatory‑defense clause, or whether intentional, non‑treatment uses of prescriptions fall outside that definition. Justice Georges pressed the point: "So is the act of the doctor writing a prescription to somehow manipulate some personal relationship, what makes that professional services?" Counsel for O'Connor responded that issuing prescriptions is a doctor's act and argued the administrative board has a legitimate interest in investigating whether those acts were professional activities.

Bench and counsel cited precedents raised below and in briefing, including decisions the parties referenced as "Roe," Hearst, and Liberty Mutual, debating whether those cases control the question of defense obligations when complaints contain mixed allegations (some arguably within coverage and some not). Several justices observed that under ordinary duty‑to‑defend principles, if any allegation within the four corners of the complaint potentially triggers coverage the insurer must defend all claims, but counsel disputed whether the particular medication allegation here is framed as negligent medical care or as intentional misconduct.

The argument also touched on technical policy features: Trundy noted the regulatory‑defense portion contains no retroactive date comparable to retroactive dates that apply to claims for damages, and he said the insured tendered defense when notified and incurred defense costs after the board proceeded to investigate. Ennis countered that the complaint, taken as written, alleges the prescription was written for a non‑medical purpose and is therefore not covered by the policy's definition of professional activity.

No decision was announced at argument. Counsel for MagMutual asked the court to affirm the Superior Court's denial of coverage; counsel for O'Connor asked the court to reverse. The court's forthcoming opinion will resolve whether the policy's regulatory‑defense provision requires MagMutual to defend Dr. O'Connor in the administrative proceeding.
