  • Dismissal of Police Officers Secured Via Sanctions Imposed

    We had our clients dismissed via sanctions imposed. On Jan. 6, 2011, Charles Sample was arrested by officers of the Philadelphia Police Department’s Narcotics Field Unit. The plaintiff alleged the officers seized $40,000 in cash from his vehicle, falsified a search warrant affidavit, disregarded proper procedures and withheld exculpatory evidence, leading to drug charges. The plaintiff entered a guilty plea for probation to avoid a lengthy prison sentence. On Jan. 6, 2017, the court granted the plaintiff’s motion for a new trial based on after-discovered evidence, and the charges were nolle prossed. The plaintiff filed his initial complaint on Jan. 4, 2019, alleging federal civil rights violations under 42 U.S.C. § 1983 and state law claims. Due to related litigation involving the Narcotics Field Unit, the case was placed in suspense on March 10, 2020, and restored to the active docket on Nov. 15, 2023. On April 4, 2024, the plaintiff filed an amended complaint, asserting six causes of action: § 1983 claims for fabrication of evidence, suppression of evidence, malicious prosecution, civil rights conspiracy, municipal liability (against the City of Philadelphia), and state law claims for false arrest, false imprisonment, malicious prosecution and conversion. On Aug. 5, 2025, Judge Gerald J. Pappert of the U.S. District Court for the Eastern District of Pennsylvania dismissed the plaintiff’s claims against the individual police officer defendants under FRCP Rule 37(b) for failure to comply with discovery orders, with prejudice. Applying the Poulis factors, the court found the plaintiff personally responsible for nearly two years of non-communication with his counsel, which prejudiced the police officers by delaying trial preparation and demonstrated a history of dilatoriness without reasonable excuse. Lesser sanctions were deemed ineffective due to the plaintiff’s prolonged unresponsiveness, and the merits of his claims could not be evaluated, rendering this factor neutral. The City’s motion to join the police officers’ sanctions motion was denied, as they did not move to compel discovery or demonstrate the plaintiff’s violation of a related court order. 

  • Summary Judgment Granted in First Amendment Retaliation Claim Case

    We were granted summary judgment in the dismissal of a First Amendment retaliation claim. The case was brought against our client, the borough manager, as well as the borough and several other of its employees. The plaintiff worked as a trash man in the Streets Department. With regard to the borough manager, the plaintiff alleged First Amendment retaliation under 42 U.S.C. § 1983, claiming a hostile work environment due to racial slurs and discriminatory behavior by coworkers and supervisors. He alleged that he reported these issues to his supervisor and the borough manager, but he felt ignored or silenced. After publicly addressing the alleged racism at a February 2024 Town Council meeting, the plaintiff was terminated a week later following a council vote. The plaintiff filed an EEOC charge and this lawsuit, alleging his termination was retaliatory and discriminatory. We were successful in having the retaliation claims against the borough manager dismissed via summary judgement, but the co-defendants remain active.

  • Summary Judgment Obtained in a Section 1983 Malicious Prosecution Case

    We obtained summary judgment on behalf of several Philadelphia narcotics police officers in a Section 1983 malicious prosecution and fabrication of evidence lawsuit. The U.S. District Court for the Eastern District of Pennsylvania dismissed the case, with prejudice, finding the record was barren of any fabricated evidence by any of the defendant officers that was ever used in or influenced any criminal proceeding against the plaintiff, the officers possessed probable cause to charge the plaintiff, and the plaintiff tendered no evidence of an underlying constitutional violation.   

  • Summary Judgment Secured in a Section 1983 Substantive Due Process Case

    We obtained summary judgment in a Section 1983 substantive due process claim involving a Philadelphia police officer. The officer had taken a photo of the plaintiff’s son after he attempted suicide by jumping off a bridge, and the photo was later circulated on social media. The plaintiff alleged that circulation of the photo violated her substantive due process privacy rights, and she also asserted a claim for intentional infliction of emotional distress. One week before trial began, the Honorable Mark Kearney, U.S. District Court for the Eastern District of Pennsylvania, held, although the plaintiff possessed a viable privacy right, that right was not clearly established at the time of the incident; therefore, the court granted qualified immunity to the officer. Additionally, the court held the plaintiff failed to present competent expert opinion evidence establishing her emotional distress and, therefore, dismissed the state tort claim for intentional infliction of emotional distress.   

  • Defense Verdict Received in Title VII/Section 1983 Sexual Harassment Case

    We obtained a defense verdict in a Title VII/Section 1983 sexual harassment case. This claim was filed against a City in Pennsylvania and was heard in the U.S. District Court for the Eastern District of Pennsylvania. The plaintiff alleged that she was subjected to a hostile work environment by a City official, and that the City failed to take appropriate remedial measures. The jury concluded that the plaintiff failed to prove that she was sexually harassed after deliberating for just over an hour.

  • Defense Verdict Secured in Section 1983 Malicious Prosecution Trial

    We secured a defense verdict in a Section 1983 malicious prosecution trial in the U.S. District Court for the Eastern District of Pennsylvania. The plaintiff alleged that our client’s law enforcement officers falsified evidence and testimony in order to maliciously prosecute him for conspiracy for engaging in the illegal sale of narcotics. We successfully contended that the former narcotics detective, who corroborated the plaintiff’s complaint, was lying, and called various members of our client’s narcotics unit to testify about the facts of the investigation.

  • Defense verdict in Pennsylvania Whistleblower Law trial.

    The plaintiff alleged she had been removed from her position as the Township Building Code Official and demoted to a lesser position in retaliation for testifying before a grand jury investigating allegations of misconduct involving a mixed-use apartment complex being developed within the Township.

  • Defense verdict in Section 1983 malicious prosecution jury trial.

    We obtained a defense verdict in the U.S. District Court for the Eastern District of Pennsylvania in a Section 1983 malicious prosecution case. The plaintiff alleged that city narcotics officers planted drugs and stole money from her and then falsely charged her with possession and possession with intent to distribute crack cocaine. The criminal charges against her were dismissed following a Post Conviction Relief Act hearing. 

  • Defense verdict for York City Police Officer in the first civil case tried in PA since the pandemic began.

    This was the first civil case tried in a U.S. District Court in Pennsylvania since the court closures caused by COVID-19. The plaintiff alleged that the police officer used excessive force in arresting her outside of a bar in the City of York. She filed a Section 1983 civil rights lawsuit, alleging she sustained a traumatic brain injury after the officer threw her head against a brick wall, threw her to the ground and then repeatedly punched her in the face. By utilizing video surveillance footage and several liability and damage experts, we were able to convince the jury that the force used by the officer was reasonable and justified by the plaintiff’s resistance. The jury deliberated for less than 30 minutes before rendering its verdict.

  • Summary judgment on behalf of a children and youth services group in a civil rights lawsuit.

    The suit was filed in the U.S. District Court for the Eastern District of Pennsylvania. The plaintiffs were the maternal grandparents of two children who were removed from the custody of their parents and placed in foster care. The plaintiffs alleged that the defendants violated their substantive and procedural due process rights protected by the 14th Amendment by failing to provide them with custody of the children and notice of court hearings. Addressing an open legal question, the court held that the plaintiffs did not stand in loco parentis to the children and, therefore, did not enjoy 14th Amendment protections. The court dismissed all claims against the county and the individual county employees.

  • Dismissal of civil rights action against a Pennsylvania children and youth agency.

    We secured a dismissal of a civil rights action against a Pennsylvania children and youth agency and several of its caseworkers and staff attorneys. ​The plaintiff parents brought their five-month-old baby to the hospital with a spiral fracture mid-shaft on his right humerus. The hospital team collectively concluded that the injury was probably accidental in nature, but a nurse reported the injury to the agency, concerned that it might have been caused by abuse. By law the agency is bound to investigate suspected child abuse and did so. A judge approved the request for a safety plan that required a chaperone to be with the parents and child, even in the home, while the merits of the abuse investigation continued. At the end of the investigation, the judge concluded the injury was accidental, and the safety plan was terminated. The plaintiffs then filed an action, alleging the safety plan violated their Fourteenth Amendment substantive due process rights. The federal district court dismissed the case, concluding the plaintiffs’ allegations of interference with the family unit, even if true, do not rise to the level of “shocking to the conscience” necessary for a due process violation. On appeal, the Third Circuit affirmed, stating that the nurse’s report of possible child abuse, in conjunction with other evidence to support suspicion of the same, make the defendants’ actions not “shocking to the conscience,” and so no substantive due process claim was stated. Dismissal was affirmed.

Pennsylvania Superior Court Reaffirms Liberal Pleading Standard in Medical Malpractice Actions

Legal Roundup: Pennsylvania The Pennsylvania Superior Court has reinforced a broader fact-pleading approach that may make it more difficult for health care defendants to obtain dismissal at the preliminary objection stage. In DaSilva v. Abington Memorial Hospital, the court held that the plaintiffs’ second amended complaint satisfied Pennsylvania’s fact‑pleading requirements despite the absence of individually named negligent actors. In DaSilva, the plaintiffs filed a second amended complaint alleging that Abington Memorial Hospital was directly and vicariously negligent after the patient, who was experiencing a mental health crisis, was left unattended by hospital staff, exited the emergency department, and was struck by a vehicle, suffering serious injuries. The trial court sustained the hospital’s preliminary objections and dismissed the complaint with prejudice, stating plaintiffs “failed to plead any material factual allegations in support of their claims of negligence [and] set forth vague allegations of negligence and unidentified agency.” Id. at *5. The plaintiffs appealed. On appeal, the Superior Court reversed, holding that the complaint sufficiently pled negligence and vicarious liability claims under Pa.R.C.P. 1019(a). The court concluded that allegations describing the patient’s condition, the hospital’s awareness of that condition, and the alleged failure to monitor or prevent elopement were adequate to satisfy Pennsylvania’s pleading requirements. Significantly, the court rejected the hospital’s argument that the complaint failed because it did not identify the specific employees responsible for the alleged negligence. Instead, the court found that generalized references to “emergency room staff” were sufficient to place the hospital on notice of the claims because “the names of those who performed services for the plaintiff are known to the defendant or can be ascertained during discovery.” Id. at *12 (citing Est. of Denmark ex rel. Hurst v. Williams, 117 A.3d 300, 307 (Pa. Super. 2015)). The effect of DaSilva is that plaintiffs may proceed past the pleading stage with relatively generalized allegations, particularly in cases involving institutional defendants where relevant details are uniquely within the defendant’s control. As a result, health care defendants should anticipate that challenges to claim sufficiency may be resolved in the later stages of litigation, including discovery and summary judgment.

The Ohio Supreme Court Extends Sham-Affidavit Rule to Contradictory Expert Reports

Legal Roundup: Ohio In its June 23, 2026, decision in Moore v. Mercy Medical Center, the Ohio Supreme Court upheld a trial court’s decision to strike an expert witness’s affidavit that contradicted the opinions expressed in the expert’s prior report. This case pertains to allegations of medical malpractice after plaintiff Cheri Moore gave birth to an infant in respiratory distress who required intubation. Moore alleged that a delay in ordering an emergency cesarean section resulted in the need for intubation, causing her child’s injuries. Specifically, Moore sued Dr. Meniru, who completed his first shift at 7:00 a.m. on May 28, 2015, and did not resume treating Moore until 7:00 a.m. on May 29, 2015. One of Moore’s expert witnesses authored a report stating that the doctors, including Dr. Meniru, deviated from the standard of care by not advocating for a cesarean section in the evening of May 28, 2015. Based on this report, Dr. Meniru moved for summary judgment, arguing that the alleged breach occurred during a period when he was not on duty. In response to the summary judgment motion, the plaintiff filed an affidavit from the same expert. Although the expert expressly incorporated his previous report into his affidavit, he also offered an additional opinion: that Dr. Meniru breached the standard of care by failing to begin a cesarean section within 30 minutes of receiving reports of fetal distress. Dr. Meniru filed a motion to strike the expert’s affidavit, arguing that it contradicted the opinions set forth in his prior report in violation of the sham-affidavit rule. The sham-affidavit rule applies to “a contradictory affidavit that indicates only that the affiant cannot maintain a consistent story, or is willing to offer a statement solely for the purpose of defeating summary judgment”. Moore, supra, at ¶ 19, citing Pettiford v. Aggarwal, 126 Ohio St.3d 413, 2010-Ohio-3237. The trial court granted both the motion to strike and the motion for summary judgment, and the Fifth District affirmed. The Ohio Supreme Court accepted two questions of law: (1) whether the sham-affidavit rule applies when the sworn testimony contradicts prior unsworn statements; and (2) whether an inconsistency within the affidavit goes to credibility or admissibility, justifying an order striking the affidavit. Previous rulings by the Ohio Supreme Court regarding the sham-affidavit rule have pertained to contradictions between an affidavit and sworn deposition testimony. See, e.g., Byrd v. Smith, 2006- Ohio-3455, 110 Ohio St.3d 24, 850 N.E.2d 47. However, here, the Court was asked to apply the same rule to contradictions between a sworn affidavit and an unsworn expert report. The Court held that, because Moore’s expert incorporated his prior report into his affidavit, he effectively adopted the report as part of his sworn testimony.

Result

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.
