hospital believed that the child was suffering from shaken baby syndrome. Muhammad did not disclose, however, that V.S. had been bedridden for six weeks, or that the hospital had concluded that T.S. had likely suffered the femur fracture while in the care of his grandmother. In reliance on Muhammad’s testimony, the Family Court judge granted a temporary order of removal, as a consequence of which T.S., after being released from the hospital on August 25, 2004, was placed in the custody of his biological father, who did not reside with V.S.
V.S. subsequently moved to vacate the order of removal, and the Family Court held a hearing on September 27 and 29, 2004, at which V.S. was once again present and represented by counsel. At the hearing, defendant Arthur testified that Dr. Eric Shakin, a pediatric retinal specialist who had examined T.S. when he was first brought to the hospital, had indicated that the retinal injuries were consistent with shaken baby syndrome. Arthur did not disclose, however, that Dr. Esernio-Jenssen had informed defendants (on September 14, 2004) that she now believed V.S. had not injured the infant. The Family Court denied the motion, and V.S. did not appeal.
ACS then proceeded with the child abuse charges filed against V.S. and her mother. At the trial of these charges, held on various days between January 24, 2005 and June 30, 2005, both Dr. Esernio-Jenssen and Dr. Shakin testified for ACS that T.S. suffered from shaken baby syndrome. For V.S., Dr. Ram Kairam, chairman of pediatrics at Bronx Lebanon Hospital, testified that although the infant had signs of retinal and vitreous hemorrhaging, they did not resemble the hemorrhages associated with shaken baby syndrome but were more consistent with childbirth injuries. This diagnosis was corroborated by medical records of injuries suffered at T.S.’s birth.
The Family Court reserved judgment, but on October 17, 2005, before any decision had been rendered, ACS moved, without explanation, to withdraw all allegations against V.S. (but not against her mother). The Family Court granted the motion and released T.S. to V.S.’s care. On November 3, 2005, the petition against V.S.’s mother was reduced to charges based solely on T.S.’s fractured femur, and on November 29, 2006, the Family Court entered a finding of neglect against V.S.’s mother.
Shortly thereafter, on January 16, 2007, V.S. commenced the instant action against caseworker Muhammad, Muhammad’s supervisor Arthur, Arthur’s manager Brenda Wilson, Wilson’s superior John B. Mattingly, and derivatively, the City of New York (collectively, the “City Defendants”), as well as Dr. Esernio-Jenssen and her employer, Long Island Jewish Medical Center, North Shore — Long Island Jewish Health System, Inc. The action alleged violations of V.S.’s and T.S.’s rights under the Fourth Amendment (search and seizure and malicious prosecution) and the Fourteenth Amendment (due process). The action also alleged claims under New York state law for malicious prosecution and abuse of process. In support of these claims, V.S. alleged, in essence, that Dr. Esernio-Jenssen had a long history of giving unreliable and misleading diagnoses of shaken baby syndrome and that ACS, knowing this, should not have proceeded in reliance on Dr. Esernio-Jenssen’s opinions and without disclosing exculpatory evidence to the Family Court.
On November 20, 2007, the City Defendants moved for summary judgment on the basis of absolute and/or qualified immunity. While the motion was being briefed, the City Defendants also sought dismissal on the basis of the so-called
