Is the SIU file privileged or discoverable
(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).”

“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
Burden to show discovery is palpably improper

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 2,600 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.

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.
