All Boro Psychological Servs., P.C. v Allstate Ins. Co., 2013 NY Slip Op 51124(U)(App. Term 2d Dept. 2013)
(1) SIU file is not priveleged
“To avoid having to produce its SIU file, defendant had to establish that its SIU file was prepared solely for litigation (Landmark Ins. Co. v Beau Rivage Rest., 121 AD2d 98, 101 ; see also Bombard v Amica Mut. Ins. Co., 11 AD3d 647 ). As defendant failed to demonstrate that it had decided to deny plaintiff’s claims prior to commencing its investigation, the contents of defendant’s SIU file are not privileged and are discoverable (Bombard, 11 AD3d at 648).”
(2) Stipulation regarding global fact not binding in other litigation
“defendant previously entered into stipulations, in unrelated actions, which, among other things, stated that, as of the date the stipulations were entered into, plaintiff was “in full compliance with any licensing requirements affecting its right to obtain reimbursement under the applicable No Fault laws and regulations.” However, as the issue was resolved in a stipulation and not after it was actually litigated, the doctrine of collateral estoppel is inapplicable”
So the Mallela compliance stipulation is at best limited to the case where the stipulation is signed. The only way to achieve what Mr. All Boro is doing appears to be through a declaratory judgment action
(3) Plaintiff bears the burden to show disclosure is palpably improper
“Since plaintiff failed to establish that the requested discovery is privileged or palpably improper, plaintiff is obligated to produce the information sought. Defendant further established its entitlement to depose Vladimir Grinberg and plaintiff’s owner, Dr. John Braun (see CPLR 3101 ;”

Legal Update (February 2026): Since this 2013 decision, New York’s discovery rules under CPLR Article 31 have undergone several amendments, and insurance industry practices regarding Special Investigation Unit files may have evolved. Additionally, subsequent appellate decisions may have further clarified the scope of SIU file discoverability and the application of attorney-client privilege in insurance fraud investigations. Practitioners should verify current CPLR provisions and review recent case law developments regarding SIU file discovery and collateral estoppel applications in no-fault insurance disputes.
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 discovery in New York civil litigation?
Discovery is the pre-trial phase where parties exchange relevant information and evidence. Under CPLR Article 31, discovery methods include depositions (oral questioning under oath), interrogatories (written questions), document demands, requests for admission, and physical or mental examinations. Discovery in New York is governed by the principle of full disclosure of all relevant, non-privileged information — but courts can issue protective orders to limit discovery that is overly broad or burdensome.
What happens if a party fails to comply with discovery requests?
Under CPLR 3126, a court can impose penalties for failure to comply with discovery, including preclusion of evidence, striking of pleadings, or even dismissal of the action or entry of a default judgment. Before seeking sanctions, the requesting party typically must demonstrate a good-faith effort to resolve the dispute and may need to file a motion to compel disclosure under CPLR 3124.
What are interrogatories and how are they used in New York litigation?
Interrogatories are written questions served on the opposing party that must be answered under oath within a specified timeframe. Under CPLR 3130, interrogatories in New York are limited — a party may serve a maximum of 25 interrogatories, including subparts, without court permission. Interrogatories are useful for obtaining basic factual information such as witness names, insurance details, and factual contentions. Objections must be specific and timely or they may be waived.
What is a bill of particulars in New York personal injury cases?
A bill of particulars under CPLR 3043 and 3044 provides the defendant with the specific details of the plaintiff's claims — including the injuries sustained, the theory of liability, and the damages sought. In personal injury cases, it must specify each injury, the body parts affected, and the nature of the damages claimed. An amended or supplemental bill may be served to include new injuries or updated information discovered during the course of litigation.
What is an Examination Before Trial (EBT)?
An EBT, commonly called a deposition, is a pre-trial discovery tool under CPLR 3107 where a witness answers questions under oath. In personal injury and no-fault cases, EBTs are used to lock in testimony, assess witness credibility, and uncover facts relevant to the case. Both plaintiffs and defendants can be deposed, along with medical experts, claims adjusters, and other witnesses. EBT testimony can be used at trial for impeachment or as evidence if the witness is unavailable.

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.
