Majestic Acupuncture, P.C. v Interboro Mut. Ins. Co., 2018 NY Slip Op 51785(U)(App. Term 2d Dept. 2018)
“The decision to grant severance (see CPLR 603) is an exercise of judicial discretion which, in the absence of a party’s showing of prejudice to a substantial right, should not be disturbed on appeal (see King’s Med. Supply, Inc. v GEICO Cas. Ins. Co., 14 Misc 3d 136, 2007 NY Slip Op 50232 ). In the instant matter, while the assignors were injured in separate accidents and defendant interposed 50 [*2]defenses in its answer, these two facts, standing alone, do not demonstrate that resolution of the claims for services rendered to plaintiff’s assignors will involve different questions of fact and law. As such, the record does not establish that the Civil Court’s denial of defendant’s motion was an improvident exercise of discretion.”
I swear there must be a different law clerk on the 15th floor who is writing these decisions. But the real losers here will be the court system and the tax payers because now the cost to prosecute these cases decreases and the cost to defend and to process the matters increases. Also, this decision goes against prior Appellate Term rulings and decisions from 3 of the 4 Appellate Divisions.
I wish the Court would be more honest and cite the two Third Department cases that are on point. Instead, they cite an 11 year old Appellate Term case that requires a quantum of proof the Appellate Divisions never held was required to sustain a severance motion.
Now, there is one judge on the panel who lived through the old Sanders Grossman multi-suits as a Civil Court Judge. I recall she was never a fan of the multisuits, but of course we are going back a decade. I await to see if she signs on to these de facto per curiam opinions.
Incidentally, of the Plaintiff produced evidence in their opposition of commonality, i.e., same fee schedule issue, or same medical necessity defense, then I wold hold that severance would be improper. But I think in these PIP actions, the Court is reversing the burden of production.

Legal Update (February 2026): Since this 2018 decision, New York’s no-fault fee schedules and reimbursement rates have been subject to periodic regulatory updates, and procedural rules governing severance in no-fault cases may have evolved through subsequent court decisions or regulatory amendments. Practitioners should verify current fee schedule provisions and recent appellate decisions regarding severance standards in no-fault litigation.
Legal Context
Why This Matters for Your Case
New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.
Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

Frequently Asked Questions
What is severance in New York civil litigation?
Severance under CPLR 603 separates claims or parties into independent actions for trial. Courts may order severance when claims involve different factual or legal issues that would confuse the jury, or when trying them together would be prejudicial to one party.
When will a court grant a motion to sever claims?
Courts consider whether the claims share common questions of law or fact, whether severance would promote judicial efficiency, and whether joinder would prejudice any party. In personal injury cases, severance of liability and damages trials is common.
What is the difference between severance and bifurcation?
Severance creates separate independent actions, while bifurcation splits a single action into separate trials (typically liability and damages). Bifurcation under CPLR 603 keeps the case as one action but tries issues separately, which is common in personal injury cases on Long Island.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
