John L. Slimm

In a case successfully tried by John Slimm, attorney in Marshall Dennehey’s Mount Laurel, NJ office, a New Jersey court upheld the 2024 board election of a major Atlantic City condominium association, rejecting claims that the process was fraudulent or fundamentally unfair. Although the court acknowledged that the community had become sharply divided and that the election season was marked by tension and mistrust, it found that the association’s procedures complied with its governing documents and state requirements. The ballot‑handling methods challenged by the plaintiffs—including coded envelopes and signatureless absentee ballots—had been formally adopted, disclosed to residents, and overseen by a neutral third‑party inspector. Throughout the litigation, the plaintiffs pointed to a series of alleged irregularities, from ballot‑collection events to delays in providing voter lists to candidates. Slimm emphasized that while these issues may have caused frustration, they did not amount to intentional misconduct or anything that could have changed the outcome. The court agreed, noting that Honest Ballot, the independent inspector, verified voter eligibility, processed challenges, and certified the results. Plaintiffs, by contrast, offered no credible evidence of ballot stuffing, fraudulent voting, or systemic disenfranchisement. The court also rejected arguments that the absence of signature verification invalidated the election, finding that neither the Master Deed nor New Jersey regulations require signatures as part of the voting process. What the rules do require—proof of eligibility and a verifiable counting method—was satisfied through the use of coded envelopes, government‑issued identification, and inspector review. Likewise, while “ballot harvesting” events did occur, Slimm successfully argued that the election rules did not prohibit bulk ballot submission, and the court found no evidence that these events altered the results. Ultimately, the court concluded that the plaintiffs had not met their burden to show fraud, illegality, or any systemic deprivation of voting rights. It declined to order a new election or impose new election procedures, instead encouraging the community to consider adopting more transparent practices voluntarily in the future. Thanks to the arguments advanced by Jack, the action was dismissed with prejudice, the 2024 election results were confirmed, and the current board remains firmly in place.

After four hearings, we obtained the dismissal of a complex legal malpractice action arising out of litigation in the U.S. District Court over the failed purchase of a Kia dealership in New Jersey. The plaintiff’s claims against our client, a well-known transactional lawyer with one of the largest firms in the United States, involved hundreds of thousands of dollars in fees and losses related to the investment in the dealership. Following the hearings, and a re-hearing, we obtained the dismissal because the plaintiff’s expert failed to tie in the damages to the alleged deviations in connection with the handling of the underlying transaction. Following the hearings, the court rejected the expert’s opinion on damages and then granted our application for a dismissal of the entire case.   

We were successful at the trial and appellate levels in a high-profile legal malpractice action. The Appellate Division’s decision came after a decade of litigation in various courts stemming from a judgment a multinational conglomerate obtained against the plaintiff and his partners in which litigation ensued over debt collection. The plaintiffs alleged the attorneys committed fraud and misrepresentation that led to the plaintiffs’ damages, which they claimed were well in excess of $10 million. We argued that the assignment agreement actually reduced the amount owed to the corporation and asked the court to dismiss the case, arguing that our client was protected by legal privilege, the statute of limitations had passed, and it had no legal duty to the plaintiff. The trial court agreed to dismiss the case, finding that the plaintiff’s claims were not supported by evidence. On appeal, the court upheld the decision, rejecting the plaintiff’s arguments. The Appellate Division found that our clients owed no duty to the plaintiff-debtors as non-clients since the attorneys’ alleged misrepresentations were made during adversarial litigation and, thus, were not intended to induce reasonable reliance by a specific non-client. This decision is extremely important to the trial bar and provides attorneys with a level of protection and immunity in connection with statements and arguments they make as adversaries in litigation.

We secured dismissal of a $10 million legal malpractice case at both the trial and appellate levels, with courts finding plaintiffs failed to provide necessary evidence or meet procedural requirements. The plaintiffs, a group of entities created for the estate planning of a now deceased married couple, appealed the trial court’s decision to deny their request to extend the time for discovery and to dismiss their claims against several defendants, including lawyers and law firms. The plaintiffs accused these defendants of negligence, breach of trust, misuse of funds, and legal malpractice related to a previous settlement and the handling of family business matters. The court found that the plaintiffs did not provide the necessary evidence or expert testimony to support their legal malpractice claims. The appeals court reviewed the trial court’s actions and found no mistake in how the court handled the case. The appeals court affirmed the trial court’s ruling, emphasizing that the plaintiffs’ inability to meet court requirements and present strong claims warranted the dismissal of their case.

We successfully defended an appeal in a complex series of legal malpractice actions arising out of an $11 million investment in an illegal venture in Brazil. In the initial trial, the plaintiff’s economic loss expert had offered a net opinion in connection with what plaintiff would have earned from the illegal venture in Brazil. We established the plaintiff’s knowledge of that illegality, which had been demonstrated in the previous legal malpractice action. Accordingly, the plaintiff’s expert report was barred in the first legal malpractice action, the doctrine of collateral estoppel applied, and the Appellate Division affirmed the trial court’s order, which barred the expert report in the second legal malpractice action. In addition, the court found that profits derived from the illegal venture are worthless and cannot form the basis for a claim.

We won a complex legal malpractice trial in Burlington County, New Jersey. The case arose out of underlying breach of employment cases where the plaintiff claimed his employer shorted him on amounts due for his salary and an electrical property. Based on the net opinions of the plaintiff’s expert, the court dismissed the legal malpractice claims during trial, and the jury awarded our client fees and costs, with interest.

We obtained a defense jury verdict in a legal malpractice action arising from two wrongful termination trials. This matter included the two trials, an appeal, in addition to involving aspects of intellectual property law. There we numerous evidence issues as a result of the two underlying trials. However, we were successful on pretrial hearing in limiting plaintiff’s proofs and in barring significant damages claims asserted by the plaintiff’s expert. The jury rejected these claims and awarded all of our client’s fees, with interest and costs.

We obtained a dismissal of an ethics grievance against a matrimonial attorney in northern New Jersey. The ethics grievance alleged that money in the grievant’s trust account was improperly handled since the ledger cards were completed incorrectly. Upon interviewing our client, the ethics investigator determined that no ethical violation was present since the money at issue was fully accounted for in the Trust account, despite the allegations by the grievant.

In this case the plaintiff, after receiving legal invoices from our client, filed a legal malpractice complaint alleging fraudulent billing. At trial, the legal malpractice claims against our client were dismissed, leaving the fee claim we asserted in the counterclaim to be decided by the jury. The jury rendered a verdict in our favor within 15 minutes for the full amount of the invoices owed to the firm, $244,759.59. This victory is significant since, pursuant to the contract the plaintiff entered into with our client, the judgment on the counterclaim will total approximately $500,000.00 in interest and attorneys’ fees.

The lawsuit involved claims of child abuse committed by a pastor that occurred during church-based camp activities. We obtained a dismissal of all counts for abuse filed by all plaintiffs against our client, one of the church defendants. Our client did not employ the pastor when the abuse occurred and had no knowledge of the claims asserted.

We obtained summary judgment in a legal malpractice matter where the underlying case concerned a matrimonial representation in a highly contested divorce. In the underlying matter, our clients represented the wife in a contentious divorce from her attorney husband.  At all times, our clients advised the wife regarding litigation strategy and the disputes concerning discovery and failure to provide documents, which delayed the matrimonial case even further. At all times, our clients aggressively represented the wife and retained competent experts to evaluate the husband’s law practice for purposes of equitable distribution. When the wife terminated the representation by our clients, they advised the wife of the risks of settling the case with her husband (an attorney) without counsel present (the advice was not heeded by the wife in the settlement of the claims). We were successful in arguing that our  clients did not deviate from the standard of care and represented the wife adequately up until the point of termination of the representation. This was potentially a multi-million-dollar case based on the size of the marital estate, and the judge granted summary judgment on behalf of the attorney defendants.

We obtained a dismissal of an ethics grievance filed against our client, a school law attorney who represented a school board and a school district. The grievance included allegations of ex parte communications with the administrative law judge, undue influence over the court, and conflict of interest based on a mediator’s spouse being retained by this attorney’s firm. We successfully argued to the disciplinary investigator that the conversations this attorney had with the administrative law judge’s staff were rudimentary scheduling and routinely conducted in cases across New Jersey. In terms of the conflict of interest alleged, we also argued that this attorney was an associate with the firm and had no interactions or decision-making authority regarding hiring of attorneys in the firm. The disciplinary ethics investigator found by clear and convincing evidence that the testimony of the school law attorney was credible, and that there was no ethical misconduct by our client. 

We defeated a plaintiff’s petition for certification to the New Jersey Supreme Court in a tortious interference and defamation action against an attorney for a lender bank. The New Jersey Appellate Division had affirmed a trial court decision granting summary judgment in a $10 million tortious interference and defamation case filed by borrowers against the attorneys for a lender bank. This case arose out of an underlying deficiency and foreclosure action filed by a bank due to the plaintiff’s failure to repay a multi-million dollar loan used to finance the purchase of real estate. During the course of negotiations to resolve the debt, the bank’s counsel had discussions with the plaintiff’s new lender. The plaintiffs alleged that during these discussions, the defendant attorney called the plaintiff a “wannabe gangster.” On appeal, Jack and Jeremy successfully argued that the trial court was correct in dismissing this case on summary judgment. The Appellate Division held that the trial judge correctly concluded that a statement made by the bank’s attorney to a potential new lender calling the plaintiff a “wannabe gangster” was mere name calling, not actionable defamation. The claims for tortious interference were based upon the lost opportunity, since the new lender rescinded its conditional commitment after the alleged statement was made. The Appellate Division held that the trial court was correct in holding that the statements were protected under the litigation privilege, that the litigation privilege is not confined to the courtroom, but extends to all statements or communications in connection with judicial proceedings. Subsequently, the plaintiff filed a petition for certification before the New Jersey Supreme Court, which we successfully opposed. The Supreme Court, in its decision, denied the plaintiff’s petition, with costs in favor of our client. 

Our attorneys obtained dismissal of an ethics grievance filed against their client, the litigation counsel for a condominium association. In this case, the attorney was able to obtain a multi-million dollar settlement on behalf of the condominium association resulting from various construction defects caused by the developer, among others. After the settlement was reached, the developer’s vice president was able to assume control of the condominium association’s board and brought ethics charges against the attorney, alleging collusion with the board president and a property manager, who acted in concert to abscond with the settlement proceeds. The ethics grievance alleged the attorney should have notified the association board of the conspiracy and should have warned the association of the theft taking place. Upon responding to the ethics grievance filed against the attorney, the defense argued that the attorney had no involvement with the president of the association or the project manager and did not have any knowledge of the conspiracy. The attorney focused on the litigation and did not involve himself in anything related to the association’s business, other than the litigation, and focused on obtaining the best settlement possible for the association against the developer. After investigating this matter, reviewing the attorney’s response, as well as interviewing the attorney, the Office of Attorney Ethics dismissed all allegations against the attorney, finding that the allegations could not be proven by clear and convincing evidence. 

We obtained the dismissal of an ethics grievance on behalf of a local special education law attorney. The grievant filed her ethics grievance based upon allegations of fraudulent and unethical practices, accusing the attorney of taking legal fees from a settlement, and alleging that the attorney was prohibited from doing so based on the terms of the settlement agreement. Specifically, the grievant alleged that the attorney failed to safeguard funds from an irrevocable trust for a special needs child, her son. In fully investigating this grievance, the District Ethics Investigator concluded that based on the evidence received, the interviews conducted and the submissions prepared on behalf of the attorney, the investigation did not reveal clear and convincing evidence that the attorney engaged in unethical conduct.

We obtained an order of dismissal through pretrial motions in a complex legal malpractice action heard before the United States District Court. It arose out of an underlying first-party coverage action that involved hundreds of thousands of dollars in connection with building damage caused by Hurricane Sandy. The plaintiffs filed a complaint against our clients, certain individuals and a law firm, alleging claims for legal malpractice.  Our motion for summary judgment filed on behalf of the defendants asserted that an order for dismissal should be entered because: (1) the plaintiffs’ expert failed to offer an opinion on causation and damages; (2) the individual claims of the plaintiffs should be dismissed since the plaintiffs did not establish an individual claim; and (3) the plaintiffs failed to come forward with proofs to satisfy the punitive damages standard in New Jersey. The court granted our motion for summary judgment.   

We obtained an order of Dismissal in favor of a municipality in connection with a lawsuit filed by a worker. ​The worker sustained catastrophic injuries as a result of a mishap on the job which caused him to fall from the roof of a condominium project under construction. This was a multi-party action in which our client, the municipality, issued the permits but failed to carry out the inspections. Notwithstanding, we were able to demonstrate immunity under the New Jersey Tort Claims Act, and the court entered the order of dismissal.

Marshall Dennehey successfully argued pre-trial motions to dismiss in the Superior Court of New Jersey, Camden County in a matter involving a $10 million tortious interference and defamation case filed on behalf of investors against an attorney and bank counsel arising out of a multi-million dollar loan for a commercial land transaction. The allegations against the attorney included slander and a claim for tortious interference, with prospective economic advantage for a contract that the plaintiff entered into with the investor. With regard to slander, we argued that the established case law in New Jersey holds that the subject pejorative was simply name calling and did not rise to the level of actionable defamation or slander in New Jersey. The court agreed and dismissed the defamation claims. Additionally, the court dismissed the plaintiff’s tortious interference claim, rejected the plaintiff’s claims of willful misconduct of the bank’s attorney and found that the plaintiff’s damages claims, although supported by expert reports, were speculative. The court agreed with the defense argument that the plaintiff’s claims for lost profits were barred by New Jersey’s New Business Rule. Under the New Business Rule, prospective profits of a new business are considered too remote and speculative to meet the legal standard to recover damages. As a result, the court entered a dismissal of the entire case.

We obtained a dismissal of a legal malpractice action arising from a Law Against Discrimination and Conscientious Employment Practices Act action against a municipality and its School Board. In this complex multi-party action, our client, an expert in school law, was retained by the school district to handle a hearing against the plaintiff, a teacher and coach. The plaintiffs alleged a conspiracy among the lawyers and the school board to oust the plaintiff. There were also allegations of malicious prosecution and malicious abuse of process against the town and its attorneys. The court granted our motion and dismissed based on the litigation privilege.

On the eve of trial, we obtained summary judgment for our attorney-client, dismissing a complex legal malpractice case in which damages were sought in connection with the underlying land transaction. ​This case included allegations that our client had multiple conflicts. The plaintiffs’ claim for damages included an allegation of $8 million in lost profits due to our client advising the plaintiffs to sell out of this business deal early, while another client of the attorney made $40 million in this deal! We were successful in obtaining dismissal by demonstrating that the plaintiffs’ experts could not prove their lost profit claim due to New Jersey’s New Business Rule and due to the fact that they could not prove any out-of-pocket damages in this case.

We obtained the dismissal of a legal malpractice/fraud action brought by a nursing home against an attorney who represented a patient and who assisted the patient in the admission process. The owners of the nursing home claimed the attorney misrepresented his client’s assets in the application and that the nursing/assisted living facility relied on that representation in admitting the patient. However, the patient had previously filed an action against the nursing home for consumer fraud, and that case was still pending when the nursing home filed the legal malpractice/fraud action against the patient’s attorney. The defense argued that the legal malpractice/fraud action was barred under New Jersey’s Entire Controversy Doctrine. The court agreed and dismissed the legal malpractice action, with prejudice.
