Christopher F. Quinlan v. Mathew M. O'Brien, M.D., Brandywine Hundred Family Medicine, LLC, and MDVIP, LLC

Quinlan v. O'Brien · Superior Court of the State of Delaware · January 13, 2026 · No. C.A. No. N24C-11-124 KMM

Summary

The Delaware Superior Court granted MDVIP, LLC’s motion to dismiss claims for medical negligence, breach of contract, and fraudulent inducement under Rule 12(b)(1) based on an arbitration agreement in the parties’ membership agreement. The court held that the agreement clearly and unmistakably delegated arbitrability issues to the arbitrator and that a valid arbitration agreement existed, while declining to reach MDVIP’s alternative Rule 12(b)(6) arguments.

Holdings

  1. The Membership Agreement clearly and unmistakably delegated substantive-arbitrability questions, including whether Quinlan's claims fall within the arbitration provision, to the arbitrator.
  2. Whether the arbitration provision complied with JAMS's procedural-fairness standards and whether JAMS was available was a procedural-arbitrability question for the arbitrator.
  3. A valid and unambiguous arbitration agreement existed between Quinlan and MDVIP.
  4. MDVIP's Rule 12(b)(1) motion to dismiss was granted because the valid arbitration agreement delegated arbitrability to the arbitrator.

Questions Presented

  1. Whether the Membership Agreement clearly and unmistakably delegated substantive arbitrability, including the scope of the arbitration provision, to the arbitrator.
  2. Whether Quinlan's challenge to the availability of JAMS and compliance with JAMS procedural standards presented a procedural-arbitrability issue for the arbitrator.
  3. Whether a valid arbitration agreement existed under Delaware contract law despite Quinlan's claims that the arbitration provision was ambiguous, indefinite, and lacked mutual assent.
  4. Whether MDVIP was entitled to dismissal under Rule 12(b)(1) based on the arbitration agreement.
