An adult son with disabilities can ask a jury to compensate him for losing his father’s care and companionship after a coach bus crash in Brookline left the father paralyzed, a federal judge in Boston has ruled. U.S. District Judge Brian E. Murphy also refused to throw out the claims against the bus driver and the bus companies, finding that a jury could decide the driver’s seizure at the wheel was foreseeable and that the companies should have seen warning signs in her driving record.
The 23-page memorandum and order in Pfeffer v. St. Clair, No. 1:23-cv-11519 (D. Mass.), is dated October 16, 2026. We read the full decision. It denies two motions for summary judgment, one by American Honda Motor Co. and one by the driver and the bus companies. None of the claims has been decided on the merits. The case now heads toward trial.

The crash
According to the facts the decision treats as undisputed, at about 5 p.m. on March 4, 2023, the father was stopped at a red light in his CR-V at Beacon Street and Charles Street in Brookline, with his wife in the passenger seat. A coach bus owned by Fullington Trailways and driven by St. Clair, a Fullington Auto Bus employee, was taking the St. Francis University track team from its hotel to dinner. The bus hit the back of the CR-V at about 17 miles per hour, pushing it into the car ahead, which was pushed into a third car. The bus pushed the CR-V and the second car about 100 yards. The father’s spinal cord was severed.
The bus kept going. When the team’s coach told St. Clair the bus had hit several cars, she had no memory of it, and she testified that she blacked out or lost awareness. Neurologists at Beth Israel Deaconess Medical Center later wrote that the most likely cause was a partial complex seizure.
The adult son’s consortium claim
Loss of consortium is a claim for the loss of a family member’s companionship, care and support caused by an injury to that family member. Massachusetts recognizes it for spouses and, since Ferriter v. Daniel O’Connell’s Sons, Inc., 381 Mass. 507 (1980), for minor children who depend on the injured parent. The Supreme Judicial Court said that dependence must be “rooted not only in economic requirements, but also in filial needs for closeness, guidance, and nurture.”
Adult children usually cannot bring the claim. The exception comes from Morgan v. Lalumiere, 22 Mass. App. Ct. 262 (1986), where the Appeals Court allowed a claim by an adult son with disabilities who lived with his injured mother and depended on her “physically, emotionally, and financially.” Later cases describe what qualifies as a “unique and intense dependency,” the phrase from Norman v. Massachusetts Bay Transportation Authority, 403 Mass. 303 (1988).
Honda argued the son could not meet that test because he is an adult who does not live with his father. The judge disagreed. According to the decision:
- The son is in his forties, has significant developmental and communication disabilities, and lives in a group home with live-in staff. He works part time.
- Before the crash, the father paid most of the group home costs, handled all of his son’s finances and benefits, took him to medical appointments, served as his point person with service agencies, and spent about 25 hours a week with him.
- Since the crash, the father is paralyzed and largely confined to his home. He cannot visit his son’s room, which is on the third floor and not wheelchair accessible.
The judge pointed out that Massachusetts courts have never made living with the parent a strict requirement. In Barbosa v. Hopper Feeds, Inc., 404 Mass. 610 (1989), the SJC refused to bar a claim by a daughter with severe disabilities just because she lived in a facility with full-time nursing care. He also noted the limits: in Mendoza v. B.L.H. Electronics, 403 Mass. 437 (1988), an adult stepchild without that kind of dependency could not recover.
Viewing the record in the son’s favor, as the summary judgment standard requires, the judge ruled that “a trier of fact could find” that the son’s reliance on his father was a “unique and intense dependency.” Honda’s motion was denied. The ruling does not decide that the son wins. It means a jury will decide.
Why the medical emergency defense did not end the case
The bus driver and companies argued that a sudden, unforeseeable seizure is not negligence. That is the law in Massachusetts: “a sudden and unforeseeable physical seizure rendering an operator unable to control his motor vehicle cannot be termed negligence,” as the Appeals Court restated in Cottrell v. Laidley (2023), quoting Ellingsgard v. Silver, 352 Mass. 34 (1967). A defendant who raises the defense at summary judgment must prove both the emergency and that it was unforeseeable with competent medical evidence.
No one disputed the seizure. The fight was over whether it was foreseeable. A treating doctor wrote in 2017 that a seizure diagnosis had been eliminated. But the plaintiffs pointed to evidence that, according to the decision, included:
- St. Clair telling EMS after the crash that she had had a seizure before;
- a 2014 episode in which she “lost awareness” while working as a taxi driver, and deposition testimony about another lapse while driving, which she later denied in her errata sheet;
- doctors’ notes and her own 2017 messages saying the episodes were hard to track and that “there are a lot of times when I just don’t realize it”;
- evidence that she did not accurately disclose her conditions on Department of Transportation medical examination forms, and that she sought to get off medications that would keep her from driving professionally.
“Because a jury could find that St. Clair knew her symptoms were more serious than she disclosed, and that her medical emergency was foreseeable, summary judgment is unwarranted,” the judge wrote.
The claims against the bus companies
The companies argued they could not have known about a condition her own doctors had not diagnosed, and that they were entitled to rely on her federal medical certificates. The judge found enough evidence for a jury on negligent hiring, negligent retention and negligent entrustment. According to the decision, the plaintiffs presented evidence that:
- her 2018 Pennsylvania driving record, which the company pulled, showed three violations and six crashes, five with injuries, and the company never asked her about them or requested police reports;
- her full driver history, showing eight crashes, was available for $9, and the company did not request it until after the Brookline crash;
- the hiring interviewer recommended her based mainly on “personality” and did not contact her previous employer;
- after she was hired, the company’s own records listed a string of at-fault crashes from 2021 to February 2023, despite a policy of automatic termination after four at-fault crashes in three years;
- a company investigator called it “concerning” that she did not know how a February 2022 crash happened, and after a March 2022 crash the other driver reported that she kept driving without acknowledging it.
The judge said this does not make bus company staff responsible for diagnosing neurological conditions. The point is that the company had information the medical examiner did not, and “a jury could find that the Fullington Defendants knew or should have known that she was unfit to drive.” Because the claim against the driver survived, so did the claims that make the employer and the bus owner responsible for her driving, including the owner’s liability under G.L. c. 231, § 85A.
The criminal conviction
A footnote reports that on October 6, 2026, the bus defendants told the court that St. Clair had been found guilty on September 29, 2026, of negligent operation of a motor vehicle and leaving the scene of a crash causing personal injury. The plaintiffs argue the conviction prevents her from relitigating negligence, and prevents the companies from contesting liability for her conduct. The companies say they were not parties to the criminal case. The judge did not decide the question but wrote that he “anticipates that Plaintiffs’ preclusion argument will prevail” on her negligence and on the companies’ derivative liability. We have not reviewed the criminal court record.
What it means for families
- Adult children with disabilities may have a claim. If an injured parent provided the kind of daily care, financial management and guidance the son received here, a consortium claim may survive even if the child lives elsewhere.
- The test is fact heavy. Courts look at the actual dependency, not age or address alone. An ordinary adult child who is close to a parent does not qualify.
- Parents have a separate statute. G.L. c. 231, § 85X, which we read at malegislature.gov, gives parents a claim for loss of consortium of “a minor child or an adult child who is dependent on his parents for support” who has been seriously injured.
- A medical emergency is a defense, not a shield. Evidence that a driver knew about warning signs, or concealed them, can send the question to a jury.
Frequently asked questions
Can an adult child sue for loss of a parent’s consortium in Massachusetts?
Usually not. The exception is an adult child with disabilities who has a “unique and intense dependency” on the injured parent, physically, emotionally and financially. In Pfeffer v. St. Clair, a federal judge ruled that a jury could find an adult son in a group home met that test.
Does the adult child have to live with the parent?
Not necessarily. The SJC in Barbosa v. Hopper Feeds refused to bar a claim just because a daughter with disabilities lived in a care facility, and this decision followed that reasoning.
Is a driver liable if a seizure caused the crash?
Not if the seizure was sudden and unforeseeable. But the driver must prove that with medical evidence, and evidence that the driver knew of prior episodes can make foreseeability a question for the jury.
Did the court decide who is at fault?
No. The judge denied summary judgment, which means the claims go forward. A jury, or a later ruling, will decide liability and damages.
