Results

Summary Judgment Obtained for School District in Slip-and-Fall Case

We secured summary judgment on behalf of a school district in Fayette County, Pennsylvania. The plaintiff alleged he sustained a concussion as a result of a fall from a loading dock when making a delivery to a middle school in the school district. He argued that the loading dock was dangerous due to inappropriate depth, causing boxes on his hand truck to strike a wall, thus pushing him off of the loading dock. The court concluded that, because of the plaintiff’s prior uneventful encounters with the loading dock, the plaintiff was aware of the intricacies of the loading dock. Additionally, the court concluded that the plaintiff was an experienced delivery driver who, as indicated, was in the best position to perceive whether conditions were dangerous or not, and was, thus, in the best position to take appropriate precautions for his safety. Therefore, the court held that the defendants had no duty to warn or otherwise act to protect the plaintiff.

Successful Appeal of Summary Judgment in Favor of Insurer

We successfully appealed a summary judgment in favor of an insurance client that had been sued by another insurance carrier for more than $1.6 million in damages arising out of a fire loss to an insured auto repair facility. The opposing insurance company had paid $1.6 million in damages and intended to pursue a product liability claim against a vehicle manufacturer, alleging a defectively manufactured vehicle had caused the fire. Our client insured the vehicle that was allegedly defective. After the insurance companies conducted a preliminary expert evaluation, the vehicle was destroyed by a salvage yard in the normal course of business. A claim was made against our client for promissory estoppel where it was alleged the vehicle was destroyed despite a promise to preserve. The Pennsylvania Superior Court affirmed the Court of Common Pleas of Erie County’s rejection of the claims against our client and agreed with our contention that the promissory estoppel claim was a disguised claim for negligent spoliation, which the Supreme Court of Pennsylvania does not recognize.

Taking vs. Tort: Which Is It in Relation to Sanitary Sewer Overflows?

March 1, 2021

Key Points: To constitute a taking, purposeful and deliberate action is required. A corrective action plan with the aim of reducing inflow and infiltration in a sanitary sewer system is evidence against the finding of a taking with respect to overflows. The failure to replace piping in an aging sanitary sewer system due to the lack of sufficient public funding does not constitute deliberate and purposeful action. In Matter of Franklin Township Sewage Authority, 233 A.3d 1014 (Pa. Cmwlth. 2020), the Commonwealth Court clarified the standard to distinguish whether a landowner damaged by repeated sanitary sewer overflows may claim that his property has been “taken” in the context of an inverse condemnation under the Pennsylvania Eminent Domain Code or whether the landowner is limited to a common law tort claim. Often this issue presents a dilemma to attorneys on both sides of the “v” in determining the legal theory applicable to the prosecution or defense of a case. Given the aging sanitary sewer infrastructure in most urban and suburban areas of Pennsylvania, coupled with the lack of sufficient public funding, this problem frequently presents itself in civil actions when damages are alleged that, if proved, might amount to the full-value level of a “taking,” although a common law tort theory such as negligence has been pleaded. In Franklin Township, the landowner commenced an inverse condemnation action by filing a petition for the appointment of a board of viewers against the Franklin Township Municipal Sanitary Authority (Authority), contending that a de facto taking of his property had resulted from repeated sanitary sewer overflows that occurred in November 2003, August 2007, and October 2012. The Authority filed preliminary objections, asserting that the petition was barred because the landowner’s proper redress was by way of a tort action. After an evidentiary hearing in the trial court, the preliminary objections were sustained, and an appeal to the Commonwealth Court followed. It was agreed that the sanitary sewer overflows onto the landowner’s property were caused by significant rainfalls that resulted in inflow and infiltration into the aging sanitary sewer system, which primarily consisted of terra cotta piping. Because the Authority attempted to reduce inflow and infiltration through a corrective action plan that involved inspections and repairs that did not intend to allow inflow and infiltration into its system, it was determined that the Authority had made a good faith attempt to fix the problem. The evidence also demonstrated that the problem could not have been eliminated unless the Authority had spent approximately $245 million to replace over 245 miles of piping. However, as with most local agencies owning aging infrastructure, the Authority did not have sufficient funding to upgrade its system. The court noted the following standard to prove a de facto taking: (1) [the] condemnor has the power to condemn the land under eminent domain procedures; (2) exceptional circumstances have substantially deprived the [landowner] of the use and enjoyment of the property; and (3) the damages sustained were the immediate, necessary, and unavoidable consequences of the exercise of the power of eminent domain. Franklin Township, 233 A.3d at 1021 (citation omitted). The court also stated that a “de facto taking must result from the governmental body’s actual exercise of the power of eminent domain.” Critical to whether a taking occurs, the court also stated, “[t]he injury complained of [must] [be] a direct result of intentional action by an entity incidental to its exercise of its eminent domain power.” In affirming the trial court, the court in Franklin Township indicated that the facts were more akin to those considered in the Commonwealth Court’s unreported opinion of In re Condemnation by the Youngwood Borough Authority, 2014 WL 10298904 (Pa. Cmwlth. Dec. 5, 2014) rather than those found in the case of In re Mountaintop Area Joint Sanitary Authority, 166 A.3d 553 (Pa. Cmwlth. 2017). The latter case, cited by the landowner, was found to involve a taking, primarily because the authority chose to operate its system in a manner that would result in sanitary sewer overflows due to the design of its system. Therefore, the overflows resulted from a purposeful and deliberate drainage plan. However, the court in Franklin Township essentially adopted the holding in the unreported Youngwood Borough Authority opinion, in essence making it precedential based on similar facts. The original sewer system of the Authority operated as intended when it was first constructed in 1968-69, utilizing terra cotta pipes. Since 2003, the landowner’s property had flooded as a result of inflow from illegally connected downspouts and infiltration due to cracks, breaks and separations that are natural to aging terra cotta pipes. The Authority had not intended to have inflow and infiltration in its system and had a corrective action plan that included a lateral inspection program to identify and repair problems. Furthermore, the Authority had even installed a check valve on the landowner’s property that stopped basement flooding, although sewage still flowed into a retention pond on the property a few times a year. Therefore, the court held that a de facto taking had not occurred because the landowner’s injury had not resulted from a purposeful or deliberate action by the Authority with respect to the manner in which it chose to operate its system. Of particular significance with respect to Pennsylvania’s aging sanitary sewer infrastructure was the court’s consideration of the evidence related to the cost to remediate the Authority’s terra cotta pipe sewage system. The trial court addressed this issue through the landowner’s argument that the Authority’s failure to replace the terra cotta piping was a deliberate and purposeful action amounting to a de facto taking. The court disagreed with the landowner, holding that, because of the lack of adequate funding, the choice to replace the entire system was not even on the table to consider. The choice would only have been available if the funding existed, and, only then, could the court have potentially found that the failure to replace the system was deliberate and purposeful so as to constitute a de facto taking.  *Christian is a shareholder and works in our Pittsburgh, Pennsylvania office.

Appellate Division Affirms Dismissal of Legal Malpractice Counterclaim Against Martin Law Firm

In Martin v. Loury, 2026 N.J. Super. Unpub. LEXIS 1617 (App. Div. July 15, 2026), Martin Law Firm represented Kirk Loury in an employment matter Mr. Loury filed against his former employer, Concord Equity Group Advisors LLC (“Concord”). The allegations included, among other things, that Loury was not fairly compensated for his employment with Concord. After a bench trial finding in Loury’s favor, the Appellate Division remanded this matter in February 2016 for a second trial. During the second trial, Concord CEO, Lee Argush, testified to lower compensation estimate than first trial. On remand, the second trial judge awarded Mr. Loury the same damages as the first judge, finding Mr. Argush not credible. After the findings during the second trial, Martin Law Firm filed an action against Mr. Loury to recover legal fees and costs of representing Mr. Loury in a second bench trial and Mr. Loury filed a counterclaim against Martin Law Firm for legal malpractice, alleging he should have received an even higher award in the second bench trial. In this allegation, Mr. Loury, through his expert, claimed that Martin Law Firm should have recalled Mr. Loury to the stand to rebut Mr. Argush’s testimony to allege an alternative theory of damages. Mr. Loury’s expert admitted that the second judge already rejected Mr. Argush's theory and accepted Loury's damages theory. The trial court barred Mr. Loury’s expert and dismissed Loury's counterclaim with prejudice before convening the collection trial, and the jury ruled in Martin Law Firm’s favor. Mr. Loury appealed the trial court's pretrial rulings barring his liability expert from testifying in support of his legal malpractice counterclaim, denying his motion for summary judgment on that counterclaim, and denying his motion to amend his counterclaim by adding attorney Joseph A. Martin as a codefendant. In affirming the trial court’s decision, the Appellate Division held that the trial court properly excluded Loury’s expert testimony in the counterclaim against Martin Law Firm because the expert could not explain how calling Loury as a rebuttal witness would have increased damages when the second judge already rejected Mr. Argush's testimony and accepted Loury's damages theory, making the expert’s causation opinion speculative. The Appellate Division also held that the trial court properly denied Mr. Loury's summary judgment motion on his malpractice counterclaim because reasonable minds could differ on whether Mr. Martin's alleged failures would have changed the second judge's damages award, given the judge already found Mr. Argush not credible, creating genuine factual disputes precluding summary judgment. Also, the Appellate Division held that the trial court properly denied Loury's May 2023 motion to add Joseph Martin individually because the statute of limitations expired in February 2022, six years after the 2016 appellate remand when Mr. Loury incurred new legal costs, and relation back did not apply because Mr. Loury knew Mr. Martin's identity throughout and strategically chose to sue only Martin Law Firm in his 2019 counterclaim.
