Key Takeaway

An assertion that a doctor’s signature was stamped did not raise a factual dispute in Manhattan Medical Imaging. The missing piece was a reason for that belief—not proof of a completed forgery.

Historical note: This 2011 decision rejected an unexplained signature objection; current CPLR 2106 has broader signer eligibility and specified exceptions, summarized in the affirmation update.

The two medical-necessity claims

Manhattan Med. Imaging v New York Central Mutual, 2011 NY Slip Op 51230(U), was decided June 30, 2011. The insurer supported its first and third claim defenses with timely-denial evidence and affirmed peer reviews containing a factual basis and medical rationale.

The provider supplied no doctor’s affirmation answering those conclusions. Its assertion that one report bore a stamped signature also failed: it gave no indication why it believed that. The court reversed denial of the insurer’s motion and dismissed those claims.

That is not a finding that stamped signatures are always valid. The opinion followed Ortho-Med’s distinction between a supported execution dispute and a bare assertion. Nor did it require the objector to prove forgery before raising an issue.

The separate IME claim

The second cause of action rested on different evidence. Affidavits established mailing of examination notices and the assignor’s nonappearance. The appellate court also granted dismissal of that claim. The signature discussion should not obscure that separate basis for relief.

Apply today’s execution rules

Current CPLR 2106 permits properly subscribed perjury affirmations for covered statements by any person. State Technology Law 304(2) recognizes electronic signatures subject to legal exceptions.

Review the particular document, how the signature was adopted and the stated basis for any objection. The method of signing, the report’s admissibility and its medical reasoning are distinct questions; none is answered merely by labeling the signature electronic.

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.

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.

No problems here. I agree. Just saying it in a conclusory fashion is nonsense. The kind of lazy lawyering that I have come to expect from certain members of the No Fault Plaintiff’s bar — say 90%.

It is nice when a Mercury Casualty case is the lead case on point for a proposition of law that makes sense..
