Portrait of Walter F. Kawalec III

Walt focuses the majority of his practice on post-trial appellate advocacy with particular emphasis in the areas of public entity liability and civil rights, insurance coverage/bad faith litigation and professional liability. He has handled several hundred appeals to date, many of which have been in representation of physicians and attorneys, in appeals connected with malpractice litigation.

In his capacity as an appellate attorney, Walt has developed extensive experience briefing and arguing cases before the Third Circuit Court of Appeals, the Supreme Courts of Pennsylvania and New Jersey, Pennsylvania's intermediate appellate courts, the Superior Court and Commonwealth Court, and New Jersey's intermediate court, the Appellate Division. As well, Walt has experience, thus far, up to the petition stage before the United States Supreme Court.

In addition to Walt's involvement in the appellate courts, he has also briefed and argued cases and motions before the Pennsylvania Board of Finance and Revenue, the Pennsylvania Courts of Common Pleas, and the New Jersey Superior Court Law Division.

Walt is a graduate of Glassboro State College and the University of Pittsburgh School of Law, where he earned his juris doctor, cum laude, in 1998. He was the recipient of the Dean's Scholarship for three years, first year moot court competition award for "Best Brief," and served as an officer in Phi Alpha Delta legal fraternity.

In 1999 Walt joined Marshall Dennehey as a member of the Appellate Group. Since that time, he has developed an proficiency in all aspects of appellate law, from legal research, brief writing and other written advocacy to oral argument, and appellate-level motion practice.

Walt's published opinions in New Jersey, Pennsylvania and the Third Circuit Court of Appeals have established and clarified important legal principles on subjects ranging from insurance coverage and remittitur, to informed consent claims in medical malpractice actions, and contributory negligence in accountant malpractice cases.

From 2002 to 2011, Walt also worked as the editor of Defense Digest—Marshall Dennehey's quarterly newsletter that updates our clients on important legal cases and issues of the day.

    • Obtained summary judgment on behalf of an obstetrician in a medical malpractice action. The plaintiff alleged that our client did not obtain the requisite informed consent from our client to undergo a trial of labor after having two prior cesarean section deliveries (“TOLAC x2”). The court found that the plaintiff’s lack of informed consent claim was without foundation as she had an awareness of the risks of TOLAC x2. Rather, the court found that her claim was premised on the assertion that the physician performing the TOLAC x2 failed to convert the TOLAC to a C-section quickly enough when complications arose. The court held that as matter of law our client had no obligation to discuss the risk that the doctor in the delivery room may wait too long to pivot to a C-section, which was the actual cause of the plaintiff’s alleged harm.
    • Successfully defended a grant of summary judgment in the New Jersey Appellate Division that resulted in a published opinion. Our clients were the owner and manager of an apartment complex for seniors. The plaintiff resident had returned from walking her dog and alleged she received injuries entering the elevator. She had allowed the dog to enter first, when the doors began to close. She alleged injuries occurring when the right door struck her arm, and when she used her left arm and left side of her body to slow the doors from closing while she leapt into the elevator.  
    • She sued our clients and the company hired to maintain the elevator, but was unable to establish any proof of negligence. The trial judge dismissed the case, declining to apply the doctrine of res ipsa loquitur, in part, because the plaintiff could not establish the third element of the doctrine: that the injury did not result from the plaintiff’s own voluntary act or neglect. On appeal, the plaintiff argued that the Appellate Division should eliminate this third element. The Appellate Division, in a published opinion, concluded that the third element is a well-established law in New Jersey and only the New Jersey Supreme Court could eliminate it, and that court has shown no inclination to do so. Because the plaintiff could not demonstrate the third prong, res ipsa was not applicable and the failure of the plaintiff to establish negligence resulted in summary judgment in the defendants’ favor.
    • Successfully argued to the New Jersey Supreme Court that the grant of a new trial by the Appellate Division in medical malpractice action was erroneous, as the plaintiff failed to object to the matter at trial and could not establish plain error.
    • Successfully argued to the US District Court and Third Circuit Court of Appeals that a municipalities decision close a property to the public during the removal of a significant amount of buried military ordinance did not constitute a constitutional violation or takings.
    • Successfully argued that the represented municipality enacted a valid regulatory ordinance and not an improper licensing ordinance notwithstanding the use of the term “license” in the ordinance.
    • Successfully briefed arbitration argument and achieved a defense result in multi-million dollar binding arbitration in construction defect case.
    • Successfully persuaded the Appellate Division to reinstate multi-million dollar complaint dismissed in the Law Division.
    • Successfully argued for the reversal of a dismissal of the insurance carrier's fraud complaint, which clarified the operation of the entire controversy doctrine in New Jersey.
    • Successfully argued that a minor deviation on the form for rejecting the stacked limits for UIM coverage was not enough to vitiate the policy-holder's rejection of stacked coverage.
    • Successfully argued that a trial court committed reversible error when, after the Appellate Division found the verdict to be excessive and remanded the case for remittitur, remitted the verdict by one cent.
    • Successfully argued that parties who were found guilty of criminal tax evasion were estopped from denying their contributory negligence in a civil suit against their accountant, stemming from the preparation of those income tax returns.
    • Successfully argued that the term "advertising injury" in policy was limited to claims arising out of the misappropriation of advertising ideas or style of doing business.
    • Successfully argued that a plaintiff who was successful against a carrier's policyholder has no claim against the carrier for the amount of the self-insured retention of the policyholder.

Successfully Overturned $1.8 Million Judgment on Appeal in New Jersey

We successfully overturned a $1.8 million judgment on appeal in a case that involved the Laidlow exclusion in a workers’ compensation/employers liability policy. The decedent succumbed to heat exhaustion while at work, and the plaintiff alleged the death was due to working conditions the employer knew were substantially certain to lead to injury. Our client, the insurer, offered to defend the employer, but only to the extent of obtaining dismissal of the workers’ compensation claim, which was filed in the wrong forum. The insured rejected the offer, and suit for the injury and coverage claims commenced. At summary judgment, the trial court refused to apply the policy’s clear and prominent Laidlow exclusion barring all coverage for claims in the Superior Court whether alleged as negligent or intentional. The trial court entered judgment in the amount of the arbitration award and awarded defense costs for the Laidlow suit, costs of the declaratory judgment action and interest. The matter went up on appeal. After briefing, but before argument, the New Jersey Supreme Court released the Rodriguez decision, which validated our client’s position on application of the Laidlow exclusion and went even further to hold that the employer’s liability carrier has no obligation to provide a defense for the common law negligence claims filed in the Superior Court. The trial court refused to apply the principles enunciated by the appellate division in the Rodriguez decision and refused to apply the reasoning of a second unpublished appellate court decision directly on point. The trial court simply ignored the cases, reasoning they were unpublished. Prior to oral argument in our matter, the Rodriguez decision was published, and the plaintiffs abandoned the case, settling for nuisance value.

Favorable Decision Obtained from the Court of Appeals for the Third Circuit

We received a favorable decision from the Court of Appeals for the Third Circuit in a First Amendment case. The circuit court affirmed the District of New Jersey’s denial of a preliminary injunction in which the plaintiff claimed that federal and local officials violated her First Amendment rights through censorship and retaliation after she posted comments on Facebook. In a published decision, the Third Circuit agreed with our arguments that the plaintiff lacked standing since she could not demonstrate a substantial risk of future harm specific to our client, the former chief of police of North Hanover, NJ, as well as the other co-defendants.

Reconsidering Reconsideration

December 1, 2021

Key Points: The standards applicable to reconsideration vary depending on whether it is a motion from an interlocutory order or a final order. Reconsideration of final orders is a much harder standard, whereas reconsideration of interlocutory orders only requires consideration of the court’s “sound discretion” and the “interest of justice.” Parties who want to seek interlocutory appeal after requesting reconsideration should take special care to file a timely motion for reconsideration so as not to miss the time limit for petition for interlocutory appeal. Let us take a moment to reconsider reconsideration. In a recent case before the New Jersey Appellate Division, Lawson v. Dewar, 256 A.3d 388 (N.J. Super. App. Div. 2021), the court took the opportunity to clarify the different standards that apply to reconsideration. In Lawson, the plaintiff filed suit against a municipality and a number of police officers, alleging the officers used excessive force when arresting him. After a case management conference, the plaintiff moved for an additional extension of discovery, the right to take certain depositions, reconsideration of an order barring a witness from testifying after the witness failed to appear for a subpoenaed deposition, leave to file an amended complaint, and for the defendant to turn over all use-of-force reports. On May 14, 2020, the court denied most of the relief sought, and the plaintiff filed a motion for reconsideration. While the reconsideration motion was pending, the venue of the case was changed from Somerset to Middlesex County. The parties argued the reconsideration motion, and the Middlesex County judge denied it. The plaintiff filed a petition for leave to appeal, which the Appellate Division granted.  On appeal, the Appellate Division first set out the legal principles that the Middlesex County judge invoked, including the coordinate-jurisdiction rule, which cautions against reversing the decisions of coequal members of the judiciary, and the law-of-the-case doctrine, that cautions against reconsidering decisions that have already been determined in the case. It also noted that the Middlesex County judge found that the reconsideration motion presented no new facts; that the plaintiff failed to show that the Somerset County judge acted in an arbitrary, capricious or unreasonable manner; that the initial decision was not based on a palpably incorrect or irrational basis; and that the previous judge did not fail to appreciate the significance of probative, competent evidence. The Appellate Division then took the opportunity to clarify the rules that apply to the two general species of reconsideration: reconsideration of an interlocutory order and reconsideration of a final order or judgment. The New Jersey Rules of Court and case law treat each differently, but they are often confused. The court noted that the principles the Middlesex County judge discussed apply to a motion for reconsideration from a final order. In that situation, Rule 4:49-2 applies, and a party must file within 20 days. Further, the standard that the Middlesex Court described—usually credited to the case of Cummings v. Bahr, 685 A.2d 60 (N.J. Super. App. Div. 1996)—applies. In motions for reconsideration after a final order, a party must demonstrate that the judge who issued the order sought to be reconsidered decided it in an arbitrary, capricious or unreasonable manner; that the decision was based on a palpably incorrect or irrational basis; or that the judge failed to appreciate the significance of probative, competent evidence. However, on motions for reconsideration of interlocutory orders, by contrast, the same standard does not apply. Rule 4:42-2 governs reconsideration of interlocutory orders and provides a far more liberal approach. Until a final order is issued, the “interest of justice” and the judge’s “sound discretion” guide reconsideration of an interlocutory order. Moreover, there is no time limit to reconsider interlocutory orders. Additionally, the Appellate Division restated that neither the coordinate-jurisdiction rule nor law-of-the-case doctrine apply to interlocutory reconsideration motions and should correct errors made by other judges when justice requires. The Lawson court, however, did not address an important consideration regarding reconsideration. While there is no time limit to petition for reconsideration of an interlocutory order, if a party wants to seek an immediate appeal of an interlocutory order, a 20-day time limit applies. A motion for reconsideration tolls that time limit, but only if the reconsideration motion is filed within 20 days. Therefore, while there is no time limit for filing a reconsideration motion on an interlocutory order, a party wishing to file a motion for interlocutory appeal after filing for reconsideration must file the reconsideration motion within 20 days or they may be out of time to seek interlocutory appeal. *Walt is a shareholder in our Mount Laurel, New Jersey, office and is a member of our Appellate Advocacy and Post-Trial Practice Group.

Congress Passes Financial Exploitation Prevention Act

On June 25, 2026, the House passed the Financial Exploitation Prevention Act of 2025 (“the Act”) by a vote of 414 to 2. The Act allows financial advisors and firms to delay suspicious transactions regarding the accounts of clients who are 65 or older, if they believe financial exploitation has occurred or is about to take place. With the advancement of technology and AI, the House’s overwhelming bipartisan passage of the Financial Exploitation Prevention Act represents an important step in strengthening the financial industry’s ability to combat the growing threat of elder financial exploitation. The Act recognizes what advisors have long known that financial professionals are often the first to detect suspicious behavior but have historically lacked clear legal authority to intervene before irreversible financial harm occurs. From the industry’s perspective, the bill accomplishes several important objectives, including the following: (1) Provides a practical “pause button” by allowing financial professionals to temporarily delay certain transaction requests when there is a reasonable belief that a senior or vulnerable adult is being financially exploited; (2) Empowers financial professionals to act by providing greater certainty that firms can act in good faith to protect clients without unnecessary legal risk; and (3) Strengthens investor protection without sacrificing client rights by allowing temporary delays based on a reasonable suspicion of exploitation, which is intended only to allow additional review and not to deny clients access to their money indefinitely. In sum, the Financial Exploitation Prevention Act will equip financial professionals with practical, carefully tailored tools to stop suspected financial exploitation before client assets are lost. By allowing firms to temporarily delay suspicious transactions under defined circumstances, Congress is recognizing the critical role advisors play as the first line of defense against increasingly sophisticated fraud schemes. The Act strikes an appropriate balance between protecting vulnerable investors and preserving individual financial autonomy, while reinforcing collaboration among advisors, families, and law enforcement to combat financial exploitation. The bill now awaits Senate action.

New Jersey Expands Family Leave Protections Effective July 17, 2026

On January 17, 2026, Governor Murphy signed into law legislation expanding the New Jersey Family Leave Act (NJFLA). Beginning July 17, 2026, significant amendments to the NJFLA will expand job-protected family leave to smaller businesses and more employees across the state. The new law broadens coverage by lowering the threshold for private employers from 30 employees to 15 employees, meaning many smaller businesses will now be subject to the NJFLA. Employees of state and local government agencies will continue to be covered regardless of the size of the employer. The amendments also make it easier for employees to qualify for leave. Under the revised law, an employee will be eligible after three months of employment and at least 250 hours worked during the preceding 12 months, replacing the previous requirement of 12 months of employment and 1,000 hours worked. Currently, New Jersey's Temporary Disability Insurance (TDI) and Family Leave Insurance (FLI) programs provide eligible employees with wage replacement while they are on leave but do not independently guarantee job protection. The recent amendments to the New Jersey Family Leave Act (NJFLA) expand these protections by extending job-protected leave to additional employees. Under the amended law, employees receiving TDI or FLI benefits may be entitled to return to the same position they held before taking leave, or to an equivalent position with the same seniority, status, pay, and benefits. Although the legislation also states that it does not expand or modify an employee's reinstatement rights under the NJFLA, the amendments appear to provide job protection to eligible employees receiving TDI or FLI benefits without requiring them to separately satisfy the eligibility requirements of the NJFLA or the federal Family and Medical Leave Act (FMLA). As a result, some employees may be entitled to longer periods of job-protected leave than were previously available under existing law. With these amendments, New Jersey continues to strengthen workplace protections by expanding access to job-protected family leave for eligible employees. These changes significantly expand access to job-protected family leave and may require employers to update their leave policies, employee handbooks, and HR practices. Notably, employers who were previously not required to administer NJFLA may need to amend their policies and/or create new protocols to come into compliance with the NJFLA. Failure to do so would prove costly, as the penalties for non-compliance are significant.

Defense Verdict in Complex Medical Malpractice Trial

Event

Florida Insurance Fraud Education Committee (FIFEC)

Sean and Alex will present, "Life Care Plans: From Low Impact to Policy Limits," focusing on the history and expanding use of life care plans in litigation and their ability to transform low impact injury claims to disproportionate high value claims. By focusing on the limitations of life care planners, Florida's tort-reform on medical damages, and the Daubert standard, extraordinary life care plans with inflated future medical care recommendations can be defended.

Summary Judgment Secured, Preserving $750,000 in Coverage for Insured in Major Trucking Liability Dispute

Ray Freudiger and Michael A. Roberts (both of Cincinnati) successfully obtained summary judgment on behalf of their client in a coverage dispute arising from a May 19, 2022, motor vehicle accident. A permissive driver operated a box truck for an interstate trucking company and caused severe injuries to two tort victims. Prior to the accident, the insured had procured a commercial auto policy for the trucking company with stated limits of $1,000,000. Following the accident, the insurer initiated a declaratory judgment action asserting that only reduced bodily injury limits of $25,000/$50,000 applied and later counterclaimed, alleging it would not have insured the driver had he been properly submitted for approval under the policy. After extensive discovery, briefing, and oral argument, the court rejected the insurer’s attempt to shift responsibility for the $750,000 in coverage it was legally required to provide for permissive drivers under Ohio law, granting summary judgment in favor of the insured and preserving $750,000 in liability exposure.

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.

Mitigating Long-Tail Liability: Delaware Court Reaffirms Five-Year Workers’ Compensation Deadline

Williamson v. Donald F. Deaven, Inc., No. N25A-07-004 FWW, 2026 LX 252526 (Del. Super. Ct. June 2, 2026) Claimant was involved in a compensable industrial work accident on May 12, 1995, for a low back injury.  Following this, he received compensation for temporary total disability benefits from July 1996 to September 1996 and for sustaining a permanent impairment in 1997 and 1998. For the next 23 years, the claimant continued treatment and paid his own medical bills without submitting them to the employer’s insurer. In November 2021, the claimant filed a petition seeking payment for medical expenses, including prospective surgery and a resulting period of total disability. The employer moved to dismiss the petition, arguing it was barred by Delaware’s five-year statute of limitations (19 Del. C. § 2361(b)). Pursuant to 18 Del. C. § 3914, insurers must provide prompt written notice of the applicable statute of limitations to invoke the five-year deadline. Due to the age of the case, neither party had a comprehensive file of the claim and the Board had archived its file of the matter. The carrier’s computer system retained only bare information indicating that payments occurred and agreements and receipts were filed with the Board in 1997. While the claimant argued that the employer could not prove it provided the mandatory statutory notice, the Hearing Officer recovered the archived file, which contained two “Receipts for Compensation Paid” signed by the claimant. The receipts explicitly contained the required five-year limitation language, which the claimant testified to signing at the hearing. The claimant also attempted to introduce evidence of payments he claimed the employer made, which would have extended the statute of limitations. As a preliminary matter, the hearing officer excluded the testimony about the payments because the claimant did not produce them to the employer. The Board found in favor of the employer and dismissed the claimant’s petition as time-barred. The claimant appealed the Board’s decision, arguing that he never received adequate notice of the statute of limitations and that the hearing officer’s evidentiary ruling was an abuse of discretion. The Court held that the archived, signed receipts constituted substantial evidence that the insurer fulfilled its statutory notice requirements. Therefore, the claimant’s petition was time-barred under the statute of limitations provisions of 19 Del. C. § 2361(b). Furthermore, the Court reinforced strict procedural compliance: it rejected the claimant’s attempts to introduce evidence of payment on appeal, ruling the argument was waived for failure to preserve it while the matter was still before the Board. This recent ruling by the Court underscores the importance and necessity of robust data preservation and precise compliance with notice requirements. For risk managers, employers, and insurers, the decision highlights how tight administrative execution protects against catastrophic long-tail liability.
