Significant Cases

Hospice company overmedicates patient for 5 years

A week before trial was scheduled to begin, SUGARMAN principals David McCormack and Benjamin Zimmermann reached a significant settlement for their client and her husband in a case involving negligent hospice care over the course of many years. SUGARMAN's client was an at-home hospice patient of the defendants for over 5 years and had been prescribed excessive and increasing amounts of narcotic pain medications to the point where she was unable to perform basic tasks. After not receiving answers to their concerns about the client's deteriorating condition, her family brought her to a local hospital, where medical providers immediately began weaning her off all the medications. The client's condition improved almost immediately. Through discovery and motion practice, SUGARMAN uncovered the hospice company's employee bonus program which incentivized employees to keep patients in hospice care and to avoid patients from being seen at hospitals or by outside providers. During the case, SUGARMAN also defeated the defendants' motion seeking to dismiss the case on various legal grounds -- a Superior Court judge found that all of the client's claims were legally and factually supported. The settlement was the second largest personal injury settlement reported in Massachusetts for 2021.

SUGARMAN obtains one of the largest reported medical malpractice settlements in Massachusetts for 2022

Substantial recovery in medical malpractice for a 14-year-old girl and her parents when, following removal of a benign brain tumor as a toddler, several doctors at a major Boston hospital failed for years to order any imaging studies to monitor the patient for recurrence of a brain tumor. While going without an MRI for over four years, the tumor recurred in the patient and grew undetected, resulting in permanent neurological injury requiring lifelong medical care. The case, which was one of the top 3 reported medical malpractice settlements in Massachusetts for 2022, resolved just before trial after SUGARMAN attorneys successfully limited the scope of the testimony of the defendant physicians’ medical experts at trial.

Pre-trial settlement for young man suffering catastrophic injuries after highway barrier failure

In the largest reported plaintiff's personal injury settlement or verdict of 2022, SUGARMAN Principals Ben Zimmermann and David McCormack obtained a recovery on the eve of trial for a 26-year-old whose vehicle was struck by a tractor-trailer that hit and tipped over a temporary barrier dividing lanes of traffic in a construction zone on a highway in Central Massachusetts. Through years of litigation in federal court, SUGARMAN was able to demonstrate that the general contractor and engineering firm for the project selected a light-weight steel barrier that did not meet the project's specifications and that the manufacturer of the barrier withheld testing and misrepresented the barrier's characteristics. Compounding these errors, the general contractor failed to install the barriers properly and the engineering firm failed to provide instructions regarding how much room was needed on either side of the barrier to prevent intrusion into opposing lanes of travel. SUGARMAN's experts demonstrated that the tractor-trailer was traveling at a low rate of speed with a small angle of impact such that a properly installed steel barrier (with several feet of room on either side) or an unpinned concrete barrier would have contained and re-directed the tractor-trailer and prevented it from entering the opposing lane of travel and striking the plaintiff’s car. The plaintiff was a healthy 23-year-old college student at the time of the collision. He suffered multiple fractures and injuries to his internal organs, ultimately rendering him paraplegic with an above-the-knee amputation of the left leg.

Verdict in labor and delivery medical malpractice case

Following a two-week trial in Suffolk County Superior Court in Boston, SUGARMAN Principals Benjamin Zimmermann and David McCormack obtained a $30.55 million jury verdict on behalf of a child who suffered permanent and catastrophic brain injuries during his mother’s labor and delivery at a Boston hospital. The jury agreed that the nurse responsible for monitoring the baby’s heart rate and well-being during labor had failed to ensure that the baby was responding appropriately and that the nurse’s failure to comply with the standard of care resulted in the baby’s severe oxygen deprivation going undetected. The jury awarded damages for both the young boy and his parents.
