Saint Peter’s Turns an OB-GYN Referral Dispute Into a Court Fight
New Brunswick, N.J.-based Saint Peter’s Healthcare System has moved a commercial dispute over OB-GYN referrals into the legal arena, filing suit against West Orange-based RWJBarnabas Health and former board member Maureen Cernadas, MD. The complaint alleges that a longtime physician leader and a competing health system worked in concert to redirect women’s health business away from Saint Peter’s while confidential information and board access were still in play.
At stake is not just a referral stream. The filing places a spotlight on how fragile physician loyalty, board governance and system-level competition can become when obstetric and gynecologic care sits at the center of regional market share.
The suit was filed Oct. 14 in the Superior Court of New Jersey in Middlesex County and includes claims of breach of fiduciary duty, aiding and abetting, civil conspiracy, unfair competition and breach of contract. Saint Peter’s President and CEO Leslie Hirsch described the conduct as improper, unethical and unacceptable in a statement released the same day.
Board Service, Private Negotiations and a Conflict Allegation
The complaint centers on Dr. Cernadas’ dual role. She led Brunswick Hills OB/GYN, a practice owned by Axia Women’s Health, while also serving on Saint Peter’s boards. Saint Peter’s alleges that she negotiated with RWJBarnabas in secret for nearly two years while holding that board position and failed to disclose a conflict of interest.
In health system governance, board service carries more than ceremonial weight. Directors are expected to protect institutional interests, especially when mergers, referral networks and physician alignment are under discussion. If those obligations are breached, the damage is rarely abstract. Referral pathways can shift quickly, and in specialties such as obstetrics and gynecology, patient loyalty often follows the physician group rather than the hospital logo.
Dr. Cernadas resigned from the board on April 15.
A single board seat can become a commercial lever when the practice it touches controls access to deliveries, outpatient gynecology and downstream imaging, surgery and maternal-fetal services.
Merger Talks, Confidential Information and an Old Deal That Never Closed
Saint Peter’s also alleges that RWJBarnabas misused confidential information obtained during merger discussions between the two systems. Those talks ended in 2022 after the Federal Trade Commission sued to block the deal.
That sequence matters because merger negotiations often create a temporary zone of trust in which systems exchange operational details, strategic priorities and market intelligence. If a prospective partner later becomes a competitor, any perception that sensitive information was repurposed can trigger a wider dispute over fairness, confidentiality and market conduct.
The allegations are especially pointed because the failed merger did not end the relationship between the systems. It simply changed the setting from negotiation to competition.
Nine Physicians, a New Venture and a Revenue Stream in Motion
The patient-facing consequences became more visible in May, when the nine Brunswick Hills physicians left Axia and formed Mid-Jersey OBGYN Partners, a joint venture with RWJBarnabas. Saint Peter’s says patients tied to the group generated about $28 million in net patient revenue for the system in 2025, and the group plans to move deliveries to RWJBarnabas after January 2027.
For a health system, OB-GYN care is not a single service line. It is a bundle of office visits, prenatal care, deliveries, postpartum follow-up and the procedural work that follows each stage of care. Once a physician group shifts its affiliation, the financial effect reaches across that entire continuum. The planned transfer of deliveries is especially consequential because childbirth is one of the most visible and recurring entry points into hospital-based revenue and long-term maternal care relationships.
In practical terms, a change in referral flow can reshape where families receive prenatal surveillance, where labor occurs and which hospital captures the surgical and inpatient components of care. The business dispute therefore mirrors a care-distribution dispute, with each side arguing over who controls the path from clinic to delivery suite.
Axia’s Parallel Claims Raise the Stakes Further
Axia Women’s Health is already pursuing related claims of its own. In May counterclaims, it accused the physicians, RWJBarnabas and three RWJBarnabas executives of misappropriating trade secrets and soliciting 31 staff members who resigned in May. The case is now in discovery, and Saint Peter’s plans to seek consolidation of the two cases.
Parallel litigation often hardens the factual record while also widening the battlefield. Here, the legal conflict is not limited to one alleged departure or one disputed board decision. It now includes questions about staffing, proprietary information, physician recruitment and the movement of an entire OB-GYN group through the regional market.
Axia called Saint Peter’s allegations “both serious and concerning.”
RWJBarnabas Denies Using Confidential Information
RWJBarnabas has denied the core allegation. George Helmy, the system’s executive vice president and chief corporate affairs officer, said the system has not sought, received or used confidential Saint Peter’s information and that the allegations are without merit. The system said it will respond in court, where the matter belongs.
Those denials set up a familiar but high-stakes dispute in health care competition: one side claims a breach of trust and a diverted patient base, while the other frames the case as an aggressive but legitimate business transition. In a market where physician groups anchor referral networks, even ordinary recruitment can look, to a rival, like strategic extraction.
The court will have to sort through whether the physician departure, the board relationship and the old merger talks crossed legal lines. The practical effect, meanwhile, is already visible in New Jersey women’s health: physicians, patients and hospital systems are now operating in a region where OB-GYN access and referral control have become the subject of active litigation.
Becker’s said it reached out to Dr. Cernadas’ attorney and will update the story if more information becomes available.
