This Is a Story About Control, Co-Owners’ Control: How Simone v. Alam Reshaped the Standard for Indispensable Parties in Premises Liability Actions

Defense Digest, Vol. 31, No. 3, September 2025

September 1, 2025

by Nicole E. Tsiaras

Key Points:

  • The Supreme Court of Pennsylvania recently held that mere ownership does not render a party indispensable in a premises liability action. 
  • The Supreme Court held that the indispensability of a party who co-owns a property that is the subject of a premises liability action hinges on that co-owner’s control and possession of the property. 

Recently, the Supreme Court of Pennsylvania established a new rule relative to indispensable parties. Specifically, in Simone v. Alam, 333 A.3d 359 (Pa. 2025), the court held that a tenant in common who did not exercise possession or control over the subject premises is not an indispensable party in a premises liability action. 

Nicole Simone, the plaintiff, alleged that she slipped and fall on an area of ice that had accumulated in the common area of a rental property owned and operated by the defendant. At the time of the alleged incident, the property was co-owned by the defendant and his brother, who was not named as a defendant. Despite knowing that the defendant and his brother co-owned the property as tenants in common, the plaintiff never sought to join the brother as an additional defendant. Instead, her position was that the defendant was solely responsible for the hazardous condition that caused her injuries as he was the property owner in possession and control of the premises.

After expiration of the applicable statute of limitations, the defendant filed a motion to dismiss, arguing that regardless of his brother’s lack of possession or control over the property, his brother’s status as a co-owner of the property made him an indispensable party. In opposition, the plaintiff maintained that the brother was not an indispensable party as he was merely a co-owner with no possession or control over the operations of the premises as a rental property. 

The defendant’s motion to dismiss was granted by the trial court and upheld by the Superior Court of Pennsylvania. Both courts held that the brother’s status as a mere co-owner of the property was enough to render him an indispensable party, thus depriving the trial court of subject matter jurisdiction and requiring dismissal of the action. 

On appeal to the Supreme Court, the issue was whether a tenant in common of real property who did not exercise possession or control over the property was an indispensable party in a premises liability action. As part of its ruling on this issue, the Supreme Court analyzed Pennsylvania Rule of Civil Procedure 2227(a), which states that an individual with a joint interest in the subject matter of an action is an indispensable party to that action. The court held that Rule 2227(a) must be construed by its plain language, enforcing that words or phrases that are expressly defined be understood in accordance with such definitions. 

Relying on Black’s Law Dictionary, the Supreme Court deconstructed Rule 2227(a) and defined a “joint interest” as one “that is acquired at the same time and by the same title as another person’s.” The court also defined “subject matter” as “the issues presented for consideration; the thing in which a right or duty has been asserted; the thing in dispute.” Using these definitions, the court construed the meaning of Rule 2227(a) to find indispensable parties as those who have the same interest in the issues presented in an action.

The court reasoned that the subject matter in a premises liability action is the liability of a possessor of property for the injuries a party has sustained as a result of a hazardous condition on that property. The court held that liability stems from the possession and control of the property, not the ownership. Applying the plain language construction of Rule 2227(a) to premises liability actions, the court ruled that a party is indispensable to a premises liability action when that party has a joint interest in the possession and control of the premises at issue.

Given its holdings, the Supreme Court declined to extend the rule set forth in Minner v. Pittsburgh, 69 A.2d 384 (Pa. 1949), reasoning that the rulings in Minner—specifically, co-owners of a property are indispensable parties due to their mere ownership interests in the property—were limited to the facts of the case. The court found that liability in Minner arose from ownership of the property since it was the sole indicator of possession and control over said property. 

In distinguishing Minner, the Supreme Court reasoned that the plaintiff’s allegations of negligence in the present matter arose from the defendant’s actions in possession and control of the property, as opposed to his status as a co-owner of the property. The court explained that the abundance of factual support pointed towards the defendant’s position as a sole landlord occupying the premises with intent to control its at-issue common areas. 

The court further explained that, as the defendant’s brother was a tenant in common, who did not exercise any possession or control over the property, he was not an indispensable party to the plaintiff’s premises liability action. As such, the court ruled that the lower courts erred in their dismissal of the action. The Supreme Court reversed the decision of the Superior Court and remanded the case to the trial court for further proceedings.

The Supreme Court’s ruling in Simone signals that a premises liability case will not be dismissed for failure to join an indispensable party based solely upon an argument of ownership. Instead, attorneys will need to establish that the indispensable party had joint interest in the possession and control of the property.

The Enforceability of Online Arbitration Agreements Remains Unresolved in Pennsylvania, But the Pennsylvania Superior Court has Provided Substantive Guidance on the Issue

Key Points: The Pennsylvania Supreme Court confirms that an order compelling arbitration is not immediately appealable as collateral orders. The outcome of Chilutti II has generally left the substantive enforceability issues with browsewrap agreements unresolved in Pennsylvania. Until this issue is resolved by the Pennsylvania courts, companies operating in the Commonwealth should strive to ensure that their registration websites and/or application screens conspicuously present arbitration agreements in manners which ensure their users and consumers assent to the terms of the agreements by following the standards set forth in Chilutti I. Browsewrap agreements have been defined as agreements “‘in which a website offers terms that are disclosed only through a hyperlink and the user supposedly manifests assent to those terms simply by continuing to use the website,’ and typically do not require an electronic signature.” See, Cobb v. Tesla, Inc., 2026 WL 458470, at *1 n. 2 (Pa. Super. Feb. 18, 2026) (citation omitted). They are largely regarded as the “if you keep using this, you agree to everything buried in this link” terms embedded into almost every online agreement consumers and users sign before proceeding with purchases of goods and/or services. While consumers are generally aware of them, many almost never click on the link, nor read them in their entirety. This leaves many consumers and users ignorant of the terms and impact of such agreements. However, one’s ignorance of the otherwise neatly-tucked-away terms rarely renders them unenforceable. The issue of the enforceability of browsewrap agreements has been up for debate for some time in many jurisdictions, including Pennsylvania. Indeed, Pennsylvania had a brief grip on this issue for a period in time. Specifically, in 2023, an en banc Superior Court set forth heightened standards for companies to meet in order to secure assent and enforce browsewrap arbitration agreements. See Chilutti v. Uber Techs., Inc., 300 A.3d 430 (Pa.Super. 2023) (en banc) (“Chilutti I”) Chilutti I involved a husband and wife who sued Uber and its subsidiaries after the wife, a wheelchair bound passenger using Uber’s rideshare service, fell, struck her head, and lost consciousness due to her uber driver failing to provide a seatbelt and making an aggressive turn during the trip. The Chilutti’s filed a negligence lawsuit against Uber and its subsidiaries. In response, the defendants moved to compel arbitration, arguing that “the couple’s conduct on the company’s website and application — when they registered for the ridesharing service — signified that they agreed to be bound by the mandatory arbitration provision found in the hyperlinked terms and conditions.” The trial court granted the defendants’ petition and stayed the proceedings pending the results of arbitration, and the Chilutti’s appealed. On appeal, the Superior Court addressed two issues. First, it addressed the issue of whether it had jurisdiction to hear the appeal. A divided Superior Court determined that it did, with its basis for the holding being that the order from which the Chilutti’s appealed was a collateral order. Next, the Superior Court set out to address the merits of the Chilutti’s substantive claim. The Superior Court concluded that the parties lacked a valid agreement to arbitrate. Its rationale was that Uber’s website and application did not provide reasonably conspicuous notice of the terms to the Chiluttis. In reaching this decision, the en banc Superior Court held that browsewrap arbitration agreements are enforceable in Pennsylvania only if the registration website and application screens explicitly inform consumers that they are waiving the right to a jury trial, the registration process cannot be completed until the consumer is fully informed of this waiver, and, when the agreement is available via hyperlink, the waiver appears at the top of the first page of the terms in bold, capitalized text. Since the ruling, Pennsylvania courts have applied Chilutti I to determine if browsewrap agreements are enforceable.  For instance, the Allegheny County Court of Common Pleas invoked Chilutti I to reject an agreement that lacked an express jury-trial waiver on the assent screen.  See Miller v. Festival Fun Parks, LLC, 92 WDA 2025 (C.P. Alleg. Cnty. Mar. 24, 2025). Similarly, the Superior Court has held that notice which failed to explicitly state the consumer was waiving a jury-trial right did not “me[e]t the strict burden set forth by our en banc Court in Chilutti I.” Pierce v. FloatMe Corp., 348 A.3d 1077, 1088 (Pa. Super. 2025). While the issue of enforceability of browsewrap agreements appeared to have been resolved by Chilutti I, Pennsylvania courts’ grip on this issue has been slackened by the Pennsylvania Supreme Court’s January 21, 2026, opinion in Chilutti II. See Chilutti v. Uber Techs., Inc., 349 A.3d 826 (Pa. 2026) (“Chilutti II”). Therein, the Supreme Court did not address the merits of the Chiluttis’ substantive claim, but rather the issue of whether the Superior Court had appellate jurisdiction to immediately review the orders staying litigation pending arbitration. The Court ultimately vacated the en banc opinion on jurisdictional grounds, holding that the Superior Court did not have appellate jurisdiction because the trial court’s order from which the Chiluttis appealed did not qualify as a collateral order and, thus, the Superior Court erred in holding to the contrary and lacked jurisdiction to entertain the merits” of the Chiluttis’ substantive claim. As such, Chilutti II has rendered Chilutti I nonbinding, and the issue of enforceability of online arbitration agreements remains unresolved. However, in light of the fact the Supreme Court did not address or comment on the merits of the Chiluttis’ appeal, Chilutti I is still meaningful. Specifically, it provides guidance as to the standards a company should strive to meet to ensure they have obtained users’ assent so that they are able to enforce online arbitration agreements. Additionally, it may serve as persuasive authority in judges’ evaluations of petitions and/or motions to compel browsewrap arbitration agreements until this particular issue is properly put before our appellate courts.

Featured Conversations... Key Takeaways from A.M. Best’s Webinar on the Misuse Defense in Product Liability Claims, Featuring Michael Salvati

Michael Salvati, shareholder in our Philadelphia office, was a panelist for the April A.M. Best webinar, “The Misuse Defense: Strategic Approaches to Defending Product Liability Claims for Insurers.” During the program, Michael and his fellow panelists offered practical, jurisdiction‑specific guidance on how misuse and failure‑to‑warn theories intersect in modern product liability litigation. Michael emphasized the unique challenges these claims present—particularly in states like Pennsylvania, where evidentiary rules diverge sharply from those applied in many other jurisdictions. Failure to Warn as the “Flip Side” of Misuse Salvati explained that failure‑to‑warn allegations often arise as a direct counter to a misuse defense. As he noted, “If our misuse defense is that the plaintiff didn't use a product properly or safely, then the failure to warn claim is that we didn't tell them how to use it properly.” He emphasized that these claims can stem from either the absence of warnings or criticisms of existing warnings, such as insufficient specificity or lack of clarity about risks. Pennsylvania’s Unique Evidentiary Landscape One of Salvati’s most notable points was the stark difference in how Pennsylvania treats evidence of compliance with industry standards. He highlighted that Pennsylvania is “one of the only states…where that evidence is not admissible” in strict liability cases. Manufacturers cannot rely on compliance with ANSI, UL, ISO, or even federal safety standards to defend the product against a strict liability claim—because the focus is solely on the product itself, not the manufacturer’s conduct. Salvati acknowledged the challenge this creates for defense counsel and clients who expect such compliance to carry weight. Understanding the Three Defect Theories Salvati also walked through the three primary defect theories recognized in many jurisdictions: - Design defect – a flaw in the product’s intended design - Manufacturing defect – a deviation affecting a specific unit - Failure to warn – inadequate instructions or warnings He noted that warnings claims are increasingly significant and sometimes stand alone when design or manufacturing theories are weak. As he put it, plaintiffs often default to warnings claims because “the default position seems to be, ‘If I got hurt, there must be something wrong.’” Warranties and State‑by‑State Variations Salvati addressed how breach‑of‑warranty claims fit into the broader framework, explaining that implied warranties—such as merchantability—often overlap with strict liability in Pennsylvania. He emphasized the importance of understanding local nuances, as warranty law and admissibility rules vary widely across states. Looking Ahead: The Growing Importance of Warnings In his closing remarks, Salvati stressed that warnings should never be treated as an afterthought in product liability defense. He observed that warnings‑only claims are becoming more common and urged manufacturers and insurers to continually evaluate the clarity and completeness of their instructions and warnings. His takeaway: “We should always be talking about what are the instructions that come with our products…to bolster a misuse defense.” Listen to the complete webinar here: https://www3.ambest.com/conferences/events/eventregister.aspx?event_id=WEB1074.

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.
