Pennsylvania Mesothelioma Verdicts and Settlements

Pennsylvania remains one of the more active states for asbestos litigation. Allegheny County and Philadelphia Court of Common Pleas are both established venues, a January 2025 Pennsylvania Supreme Court ruling reopened employer liability for workers diagnosed decades after their last exposure, and Philadelphia’s coordinated mass-tort program continues to grow. The state’s steel mills, naval shipyards, and industrial manufacturing plants created exposure pathways spanning many product manufacturers, which is why most cases name multiple defendants.

Major Pennsylvania Mesothelioma Verdicts

Chirdon v. Foster Wheeler LLC, $3.8 Million (2024, On Appeal)

In September 2024, an Allegheny County jury awarded Harry and Rae Chirdon $3.8 million against Foster Wheeler LLC (Allegheny County Court of Common Pleas, GD 22-016244, Hon. Arnold Klein presiding). The jury awarded $1.95 million in compensatory damages to Harry Chirdon, $350,000 in loss of consortium to Rae Chirdon, and $1.5 million in punitive damages.

Chirdon worked as a union boilermaker from 1967 to 1988 and spent roughly 10 weeks at Foster Wheeler during that career. He was diagnosed with malignant mesothelioma in November 2022. Foster Wheeler LLC was the sole remaining defendant at trial. David Halpern of Halpern Law Firm served as lead plaintiff counsel.

Judge Klein denied Foster Wheeler’s post-trial motions to strike or reduce the verdict in June 2025. Foster Wheeler filed an appeal with the Pennsylvania Superior Court. The Superior Court then ordered the trial court to enter judgment in the consolidated cases so Foster Wheeler could properly perfect the appeal. That appeal is pending as of August 2025. The punitive damages component is likely to be a focal point on review.

Estate of William Herold v. University of Pittsburgh, Appellate Ruling (2025)

The most significant Pennsylvania mesothelioma development of 2025 is the Pennsylvania Supreme Court’s ruling in Estate of William Herold v. University of Pittsburgh, 22 WAP 2023, decided January 22, 2025, by a 5 to 2 vote. Justices Wecht and Brobson dissented.

The court held that the Pennsylvania Occupational Disease Act’s exclusivity provision does not preclude common-law negligence claims for occupational disease that manifests more than four years (300 weeks) after last asbestos exposure. The question of whether the workers’ compensation system had primary jurisdiction over those employer claims was addressed by the Commonwealth Court in the lower proceedings (No. 998-CD-2021, Feb. 16, 2023), and the Supreme Court’s opinion focused on the ODA exclusivity holding.

William Herold worked as a stationary engineer at the University of Pittsburgh from 1976 to 2004, with asbestos exposure during that period. He later became a foreman with no further asbestos contact and retired in 2015. He was diagnosed with mesothelioma in April 2019, roughly 15 years after his last exposure, and died in April 2022. The Supreme Court remanded the case to Allegheny County Court of Common Pleas (GD-19-014532) for trial proceedings. No damages have been awarded yet.

For workers diagnosed with mesothelioma in Pennsylvania, the practical effect is significant. Before Herold, workers whose latent disease appeared after the 300-week ODA window could be pushed toward workers’ compensation as their exclusive remedy against their employer. After Herold, those claimants can pursue common-law negligence actions.

Merwitz v. Allis-Chalmers Corp. Product Liability Trust et al., $7.25 Million Total (2014, Entered)

On March 13, 2014, a Philadelphia Court of Common Pleas jury returned a $7.25 million verdict in Merwitz v. Allis-Chalmers Corp. Product Liability Trust et al. (Case ID 101101848, Hon. Victor J. Dinubile Jr. presiding): $3.6 million in survival damages and $3.6 million in wrongful death. Edward Merwitz worked as a shipfitter at the Philadelphia Naval Shipyard from 1965 to 1970. He was diagnosed with mesothelioma in January 2010 and died approximately six months later at age 62.

The headline number requires context. Eight defendants, including Buffalo Pumps, Westinghouse/CBS Corp., Blackmer Pumps/Dover Corp., GE, Greene Tweed, Square D, Warren Pumps, and DeLaval, settled before the verdict at confidential amounts. RSCC Wire & Cable LLC (formerly Rockbestos-Surprenant Cable Corp.) was the only defendant remaining at verdict and was apportioned $805,250 of the total ($403,772 survival + $401,478 wrongful death). No appeal or post-verdict modification has been confirmed in neutral sources.

This structure, a large headline verdict with most recovery absorbed by pre-verdict confidential settlements and a much smaller amount apportioned to the trial defendant, is a recurring feature of Pennsylvania shipyard and industrial asbestos cases.

Why Pennsylvania Courts Matter for Asbestos Cases

Philadelphia and Allegheny County are established mass-tort venues. The Philadelphia Court of Common Pleas runs a coordinated asbestos program through the Complex Litigation Center, with cases organized into trial groups of up to 10 under a global case management order. Philadelphia reported 267 new asbestos lawsuits in 2024, an approximately 11% increase over 2023 (approximately 241 filings), per KCIC’s Asbestos Annual Report 2024.

Pennsylvania’s industrial history, steel production, Naval shipyard work, heavy manufacturing, and commercial construction, means that exposure evidence tends to span multiple employers and product manufacturers. Bethlehem Steel, for example, filed Chapter 11 bankruptcy in October 2001, and recovery for steelworkers now runs through asbestos bankruptcy trust funds and through claims against the product manufacturers that supplied the mills.

Pennsylvania’s Filing Deadline

Pennsylvania imposes a two-year statute of limitations for personal injury actions under 42 Pa. C.S. § 5524, subsection (2). The same two-year period applies to wrongful death actions.

Two cases define how the limitations period applies to latent asbestos disease in Pennsylvania:

• Cathcart v. Keene Industrial Insulation, 471 A.2d 493, 324 Pa. Super. 123 (Pa. Super. 1984): The Pennsylvania Superior Court (en banc) recognized the discovery rule for asbestos claims. The limitations period does not begin until the plaintiff knows or through reasonable diligence should know of the injury and its cause. The court noted that invoking the discovery rule carries a heavy burden of inquiry on the party seeking to rely on it.

• Wilson v. El-Daief, 964 A.2d 354, 600 Pa. 161 (Pa. 2009): The Pennsylvania Supreme Court held that the discovery rule tolls the statute of limitations for latent injuries until the plaintiff knew or should have known she was injured by the conduct of another, and that whether reasonable diligence was exercised is ordinarily a jury question.

For mesothelioma, which typically appears 20 to 50 years after exposure, the discovery rule usually ties the clock to the date a licensed physician diagnoses the disease and informs the patient of its asbestos connection. Two years is a shorter window than many neighboring states, so investigation should begin as early as possible after diagnosis.

Settlements and Asbestos Trust Funds

Most Pennsylvania mesothelioma cases do not reach a jury. Companies that manufactured asbestos-containing products and later filed for bankruptcy are required to fund asbestos trusts as part of their reorganization plans. Workers exposed to insulation, gaskets, pipe covering, and similar products at Pennsylvania steel mills, power plants, and shipyards often qualify for claims against multiple trusts, even where the manufacturing companies no longer operate.

Settlement amounts in mesothelioma cases vary widely based on the strength of the exposure evidence, the number of liable defendants, the diagnosed disease stage, and the specific products and worksites involved. The verdicts described on this page reflect cases that went to trial; the majority of resolutions happen through confidential pre-trial settlements or trust fund distributions.
