In Keith v. Hart, Judge Caproni denied defendants’ motion to exclude Dr. Jain’s expert testimony about Keith’s shoulder injury.
The ruling allows Keith Monterey to present Dr. Nidhi Jain’s expert testimony in support of his underlying claims and leaves the defendants free to challenge that testimony through cross-examination.
What happened
Keith v. Sgt. William Hart concerns an arrest during which Keith Monterey says police officers pulled his handcuffed arms behind his back and injured his shoulder. He planned to have Dr. Nidhi Jain testify that his MRI findings were consistent with that alleged force.
The defendants argued that Dr. Jain was not qualified and that her opinion was irrelevant and unreliable because she did not examine Keith, fully explain her reasoning, or perform a differential diagnosis. The court disagreed, finding that her medical training, review of Keith’s records and MRI, and explanation of the shoulder injury provided a sufficient basis for her testimony. The court said the defendants could challenge the opinion through cross-examination.
Judge Valerie Caproni denied the defendants’ motion to exclude Dr. Jain’s report or testimony and directed the clerk to close the motion. The ruling addressed the admissibility of evidence, not whether Keith ultimately proved his arrest or excessive-force claims.

Background
The case arose from Keith Monterey’s April 17, 2016 arrest by members of the New York City Police Department. Keith alleged that officers shoved him to the ground, handcuffed him, and lifted him by his arms while they were restrained behind his back, causing a left-shoulder injury. The court had previously denied summary judgment on certain false-arrest, fair-trial, excessive-force, and failure-to-intervene claims.
The motion at issue was the defendants’ request to exclude testimony from Dr. Nidhi Jain. Keith planned to call Dr. Jain, a board-certified radiologist, to testify that his shoulder injury was consistent with having his arms pulled forcefully behind him. Dr. Jain reviewed medical records, a December 21, 2016 MRI, and Keith’s deposition. Her report identified a low-grade sprain of the inferior glenohumeral ligament and concluded that the injury was consistent with trauma involving sudden force.
Rule for Expert Testimony
Federal Rule of Evidence 702 permits a qualified expert to testify when the testimony will help the factfinder, is based on sufficient facts or data, uses reliable principles and methods, and reliably applies those principles and methods. The court serves as a gatekeeper, meaning it must screen expert testimony for relevance, qualifications, and reliability.
Relevance
The court found Dr. Jain’s testimony relevant to Keith’s unlawful-arrest and excessive-force claims. The testimony could help show whether force was used, whether the alleged force caused the shoulder injury, and the extent of damages. The court also found the testimony helpful because Dr. Jain stated that the injury was consistent with the alleged sudden force. The court rejected the defendants’ argument that the report was irrelevant because it did not expressly state that the defendants caused the injury.
Qualifications
The defendants argued that Dr. Jain could not testify because she was a radiologist rather than an orthopedist. The court rejected that argument. It found that Dr. Jain’s medical degree, board certification in radiology, and specialized training in diagnostic and musculoskeletal radiology qualified her to interpret Keith’s MRI, diagnose the ligament sprain shown on it, and offer an opinion about how that injury might have occurred. The court said any dispute about her specialization affected the weight of her testimony, not whether it could be admitted.
Reliability
The defendants argued that Dr. Jain’s opinion was unreliable because she did not physically examine Keith, did not adequately explain how the MRI showed a sprain or how the injury matched the alleged force, and did not perform a differential diagnosis. A differential diagnosis is a process doctors use to identify the most likely cause of an injury by considering and eliminating possible causes.
The court found that a physical examination was not required. Dr. Jain relied on medical records, the MRI, and Keith’s deposition, which the court found gave her good grounds for the opinion. The court also found that her explanation—that the injured ligament stabilizes the shoulder and that this type of sprain is unusual without sudden force—provided an adequate foundation. The court determined that her medical experience and the materials she reviewed supplied sufficient reliability even though her report did not give a detailed step-by-step account of how she interpreted the MRI.
The court further held that Dr. Jain did not have to provide an explicit differential diagnosis. It treated her as Keith’s treating physician because he had consulted her before filing the action, and it found that her review of his records and deposition provided additional reliability. The court also said her report implicitly addressed other possible causes by stating that the injury was unusual without trauma involving sudden force. Any remaining criticism could be explored through cross-examination and went to the testimony’s weight rather than its admissibility.
Disposition
Judge Valerie Caproni denied the defendants’ motion to preclude Dr. Jain from offering her report or testifying. The court also directed the clerk to terminate the open motion at docket entry 78. The court did not decide the ultimate merits of Keith’s underlying claims in this opinion.
