Costco Sonoma County Lawsuit | $14M Brain Injury Claim

Sadie Novotny was shopping at the Costco on 1900 Santa Rosa Avenue with her husband on March 22, 2025, when a large, heavy liquor cabinet display fell on her without warning. The cabinet had thin legs. It was sitting on a worn wooden pallet. According to the lawsuit she filed weeks later, Costco knew or should have known the setup was dangerous. She is suing for $14,110,000 in damages, alleging general negligence, premises liability, and products liability.

The case, Novotny v. Costco Wholesale Corporation et al., Case No. 3:2025cv04786, was filed April 29, 2025, in Alameda County Superior Court and moved to the U.S. District Court for the Northern District of California on June 5, 2025, at Costco’s request. A case management conference was scheduled for September 4, 2025, at the San Francisco Federal Courthouse. No settlement or verdict has been publicly announced. Costco has not issued a public statement on the lawsuit.

Lawsuit Timeline and Updates

March 22, 2025 — The Incident at Santa Rosa Costco

Sadie Novotny and her husband were shopping at the Costco Wholesale store at 1900 Santa Rosa Avenue in Santa Rosa, California. They were in the area of a liquor cabinet display that was on sale when the floor model fell on top of her. In her own words, recorded in a Costco incident report filed the same day: “My husband and I were buying a liquor cabinet. I was holding the flatbed when the floor model fell on top of me. I caught the cabinet and pushed it back. My right shoulder, forearm, hand, fingers, and lower back hurt after the accident.”

Novotny did not go to the emergency room immediately. She left the store with her husband but told him she felt “really bad.” An hour after the incident, she went to the hospital. Doctors diagnosed her with a concussion. Her attorney, Claude Wyle, a partner at Choulos, Choulos and Wyle in San Francisco, later told media that her symptoms persisted well beyond the initial diagnosis: ongoing headaches, vision problems, and difficulty finding words.

April 29, 2025 — Lawsuit Filed in Alameda County Superior Court

Novotny’s legal team filed the complaint in California Superior Court for Alameda County on April 29, 2025. The filing named Costco Wholesale Corporation as defendant and brought three claims: general negligence, premises liability, and products liability. The complaint sought $14,110,000 in total damages.

The choice to file in Alameda County, not Sonoma County where the incident occurred, drew brief attention in local press coverage. Court records did not include an explanation for the venue selection. Costco was formally served with the complaint on May 7, 2025.

June 5, 2025 — Case Moved to Federal Court

Costco’s counsel filed a removal notice on June 5, 2025, transferring the case to the U.S. District Court for the Northern District of California in San Francisco. Costco’s justification for removal cited the company’s Washington state incorporation, establishing the diversity of citizenship required to invoke federal jurisdiction. The case was docketed as Case No. 3:2025cv04786.

Moving to federal court is a common defense tactic in large personal injury cases. Federal courts operate under different procedural rules and timelines than California state courts. The move lengthened the case timeline and set the stage for a federal discovery process, including depositions, document production, and expert witness designations.

June 10, 2025 — National Media Coverage Breaks

USA TODAY, NBC News, CBS News, ABC7, and People magazine all published coverage of the lawsuit on and around June 10, 2025. The $14.1 million figure and the traumatic brain injury allegation drove wide pickup. Attorney Claude Wyle gave interviews explaining the severity of Novotny’s ongoing symptoms and the legal theories underlying the complaint. The coverage drew widespread social media commentary, much of it skeptical of the damages sought.

Wyle pushed back on the dismissive framing. “She suffered a head injury. We don’t know how bad it is yet,” he told ABC News at the time. The lawsuit itself raised the possibility of long-term neurological consequences, including early dementia, tied to the traumatic brain injury.

September 4, 2025 — Case Management Conference

A case management conference was scheduled for September 4, 2025, at the San Francisco Federal Courthouse. Case management conferences in federal court set the procedural roadmap for the litigation: discovery deadlines, expert witness schedules, dispositive motion timelines, and, eventually, a trial date. No public filings or statements emerged from the conference that altered the known facts of the case.

At this stage, the litigation moves largely out of public view. Discovery in federal civil cases is not filed on the public docket unless a party files a motion requiring judicial resolution. The evidentiary battle over security footage, Costco’s inspection and merchandising records, and Novotny’s medical documentation was underway.

2026 — Case Remains Active, No Settlement Announced

As of May 2026, no settlement or trial outcome in Novotny v. Costco Wholesale Corporation has been publicly confirmed. The case proceeds through pre-trial proceedings in the Northern District of California. Personal injury cases of this complexity typically take two to four years from filing to resolution, particularly when a corporate defendant like Costco contests liability and disputes the damages calculation.

What the Lawsuit Alleges

The complaint frames the Santa Rosa incident as a failure of Costco’s store management, not an unforeseeable accident. The legal argument rests on three overlapping theories, each targeting a different aspect of how the retailer operates and maintains its warehouse floor.

General Negligence

The core negligence claim alleges that Costco breached its duty of reasonable care to shoppers by allowing a dangerous display condition to exist. The complaint states that Costco “negligently failed to adequately manage and or operate their store and or their merchandise” and “negligently failed to train, manage and supervise their employees.” Both failures, the lawsuit argues, were substantial factors in causing Novotny’s injuries.

Negligence in a retail setting requires proving that the hazard existed, that the store knew or should have known about it through reasonable inspection, and that the failure to address the hazard directly caused the plaintiff’s injury. Novotny’s legal team argues the cabinet’s thin legs and worn pallet created a visible, discoverable danger that no reasonable inspection should have missed.

Premises Liability

Premises liability holds property owners and occupiers responsible for injuries caused by unsafe conditions on their property when they knew or should have known about the hazard. Costco, as the operator of the Santa Rosa warehouse store, owes customers the duty of a reasonably safe shopping environment. The lawsuit alleges the liquor cabinet display was “set up in an unreasonably dangerous manner” and that Costco failed to either fix the hazard or warn customers of the risk.

Falling merchandise cases carry particular weight in premises liability litigation because they implicate systemic store practices rather than an isolated spill or transient hazard. A display that falls because it was improperly staged raises questions about inspection protocols, employee training, and corporate standards for floor displays across the entire chain.

Products Liability

The products liability theory frames the cabinet or its display fixture as a defective product. The complaint describes the cabinet as having thin legs and being placed on a defective or worn wooden pallet, creating an inherently unstable configuration. This theory allows the plaintiff to pursue Costco not just as a negligent property occupier but as a seller or distributor of a product that presented an unreasonable danger in its displayed condition.

Products liability claims can be difficult in retail display cases because the fixture, not the cabinet itself, may be the real hazard. The legal teams will litigate whether the cabinet’s design, the pallet’s condition, or Costco’s staging decisions were the proximate cause of the fall.

The Injuries

Novotny’s complaint describes “multiple, permanent, and catastrophic” injuries. The most serious is a closed head injury and traumatic brain injury. Traumatic brain injuries are legally significant because their full consequences may not be immediately apparent at the time of injury and because long-term effects can include cognitive impairment, memory loss, chronic headaches, vision disturbances, and, according to medical testimony cited in coverage of the case, increased risk of early dementia.

In addition to the head injury, Novotny reported immediate pain in her right shoulder, forearm, hand, fingers, and lower back at the time of the incident. These injuries align with her own account: she caught the falling cabinet and pushed it back, meaning her upper body absorbed the initial impact force of the display before it fully toppled.

Ongoing symptoms reported by Novotny as of June 2025 included persistent headaches, vision problems, and word-finding difficulties. These are consistent with post-concussion syndrome, a condition that can persist for months or years after the initial head injury. The severity and duration of these symptoms directly drive the size of the damages sought.

Damages Breakdown

The $14,110,000 demand is specific and itemized. It is the amount Novotny’s legal team contends she is entitled to if the case goes to trial and the jury accepts the full scope of her claimed damages. It is not a guaranteed award. Courts can award less, more, or nothing depending on the evidence and legal standards applied.

The ratio of non-economic to economic damages is notable: $10 million in pain, suffering, and emotional distress versus $4.1 million in quantifiable financial losses. Non-economic damages in California personal injury cases are not capped for general negligence claims. A jury can award what it believes the evidence supports. Traumatic brain injuries, because of their potential for long-term cognitive impairment, routinely support large non-economic damage awards when medical evidence is strong.

The Security Footage Question

One evidentiary issue flagged by Novotny’s attorney at the time of filing is access to the security camera footage from the Santa Rosa Costco. Costco, like all large warehouse retailers, maintains extensive video surveillance of its store floor. Footage of the incident itself, and of the display in the hours and days before the fall, could be decisive evidence for either side.

Footage showing the cabinet display in a clearly precarious position prior to the fall would support Novotny’s argument that Costco knew or should have known the hazard existed. Footage showing a properly staged, stable display that fell due to some action by Novotny or her husband would support Costco’s defense. The existence, preservation, and production of that footage in federal discovery is one of the key evidentiary battles in this case.

Spoliation of evidence, meaning the destruction or failure to preserve potentially relevant evidence, carries serious consequences in federal litigation. If Costco did not preserve footage from the date of the incident and surrounding days, Novotny’s attorneys could seek an adverse inference instruction at trial, telling the jury that the missing footage should be assumed to show what the plaintiff alleges.

Why Costco Moved the Case to Federal Court

Costco’s decision to remove the case from Alameda County Superior Court to federal court reflects standard large-defendant litigation strategy. Federal courts in Northern California operate under the Federal Rules of Civil Procedure, which give defendants more structured discovery timelines and somewhat greater ability to manage expert witness disclosures.

The diversity jurisdiction basis for removal, Costco’s Washington state incorporation versus Novotny’s California residence, was straightforward. The amount in controversy, at $14.1 million, well exceeded the $75,000 federal diversity jurisdiction threshold. Costco’s decision to remove was legally uncomplicated.

From a strategic standpoint, federal court also tends to move cases on a predictable docket schedule, which benefits well-resourced corporate defendants who can sustain a longer litigation timeline. Large personal injury plaintiffs are often under financial pressure from ongoing medical expenses and lost income, which can create settlement leverage for defendants willing to wait.

Costco’s History with Retail Injury Lawsuits

Costco faces personal injury lawsuits regularly. The company operates over 800 warehouse stores globally and has millions of daily shoppers. Slip-and-fall cases, falling merchandise claims, and parking lot accidents generate a consistent stream of civil litigation. Most are resolved confidentially through settlement well before trial.

What distinguishes the Novotny case is the combination of injury severity, the specific type of hazard alleged, and the scale of the damages sought. Falling merchandise cases that involve large, heavy display fixtures raise systemic questions about store-wide merchandising standards. A finding of liability here could affect how Costco stages floor displays chain-wide, not just at the Santa Rosa location.

For broader context on how retailers handle product liability and premises safety litigation, our coverage of the General Motors V8 engine lawsuit and the Shannon Sharpe sexual assault lawsuit settlement illustrate how large corporate defendants manage high-profile litigation through the settlement process when trial risk becomes substantial.

What Happens Next

The case is in active pre-trial proceedings in the Northern District of California. After the September 2025 case management conference established a scheduling order, the parties entered the discovery phase. Both sides are conducting depositions, producing documents, and designating expert witnesses. Medical experts on the nature and extent of Novotny’s traumatic brain injury will be central to the damages phase. Costco will retain its own experts to evaluate causation, the display’s design, and the adequacy of its merchandising protocols.

Personal injury cases of this scale in federal court typically resolve through one of three paths: settlement during or after discovery, summary judgment in Costco’s favor if the evidence fails to support negligence causation, or a jury trial. Settlement is statistically the most common outcome. Large retailers rarely want a public jury verdict on store safety practices, and a $14 million demand in a traumatic brain injury case carries real trial risk for Costco regardless of its confidence in the defense.

No trial date has been publicly set. Based on typical Northern District of California civil case timelines, a trial, if the case does not settle, is unlikely before 2027.

What This Lawsuit Teaches Consumers

The Costco Sonoma County lawsuit draws attention for the dollar figure. That is the wrong lens. The more important question is what the lawsuit says about how warehouse retailers stage heavy merchandise on their floors.

Costco’s business model depends on floor displays. Pallets of merchandise. Floor models. Large, heavy items positioned for customer interaction. The operational logic is to put the product in the shopper’s path, close enough to examine and move toward the flatbed cart. The physical reality is that this creates contact points between customers and heavy, sometimes improperly secured fixtures.

Novotny’s complaint does not describe a freak accident. It describes a cabinet with thin legs on a worn pallet that someone could look at and recognize as unstable. The question at trial will be whether Costco’s inspection and training systems were designed to catch exactly that kind of hazard before a customer got hurt.

That question matters beyond this case. If Costco’s floor display standards are found deficient by a federal jury in San Francisco, the result is not just a damages award. It is legal precedent that plaintiffs’ attorneys in other jurisdictions will use to hold warehouse retailers accountable for the same category of failure. Retailers that rely on floor models and pallet displays should be watching the outcome of Novotny v. Costco closely.

For shoppers, the practical lesson is simpler. When you approach a floor model display in a warehouse store, particularly large furniture, cabinetry, or appliances on elevated bases, look at the base. Check the pallet condition. Notice whether the item is braced or secured. If something looks unstable, do not touch it before alerting a store employee. The retailer’s duty to keep you safe does not end at the aisle entrance.
