People v. Decina

2 N.Y.2d 133 (1956)

Quick Summary

Quick Summary Icon

Decina, (the defendant), caused a fatal accident while driving because of an epileptic seizure and was charged of criminal negligence. The dispute centered on whether his prior knowledge of his condition amounted to negligence and if his medical history was admissible in court.

The Court held that Decina’s decision to drive despite being aware of his condition constituted criminal negligence, but deemed his medical history inadmissible due to physician-patient privilege. The lower court’s ruling on culpable negligence was upheld, but admission of Dr. Wechter’s testimony was found improper.

Facts of the Case

Facts of the case Icon

Emil Decina (defendant) was operating his vehicle when he suffered an epileptic seizure, which resulted in his car careening out of control. The car sped up, jumped a curb, and tragically struck and killed four young pedestrians. Decina was then charged with criminal negligence in the operation of a vehicle resulting in death.

He contested the charges, arguing the court had accepted improper testimony and had erred in overruling his demurrer to the indictment. The appellate division ordered a new trial based on the testimony issue, but upheld the demurrer decision. During the incident, Decina’s car was seen veering across lanes and sidewalks at high speeds, ultimately crashing into a grocery store.

Witnesses described Decina as appearing dazed or unconscious during the event. After the accident, he resisted arrest and was taken to a hospital where he recounted his medical history of epilepsy to Dr. Wechter. This conversation became a point of contention in the trial as it was the key evidence indicating Decina’s awareness of his condition and its potential consequences while driving.

Whether Emil Decina’s knowledge of his susceptibility to epileptic seizures and decision to drive regardless constituted criminal negligence under section 1053-a of the Penal Law, and whether the testimony regarding his medical history was admissible.

Rule of Law

Rule Icon

The rule of law in this case is that criminal negligence can occur when an individual, aware of a condition that may render them incapacitated, chooses to engage in an activity such as driving, which can result in dangerous consequences. This rule also extends to the admissibility of evidence and physician-patient privilege, particularly concerning information necessary for medical diagnosis and treatment.

Reasoning and Analysis

Reasoning Icon

The Court reasoned that Decina, knowing he was subject to unpredictable epileptic seizures, consciously chose to drive, thus disregarding the possible fatal consequences. The Court found that such conduct demonstrated a disregard for others’ safety and fulfilled the criteria for culpable negligence.

Additionally, the Court examined whether the conversation between Decina and Dr. Wechter at the hospital was protected under physician-patient privilege. It concluded that the presence of a police guard did not negate this privilege, as the information was necessary for medical diagnosis and treatment, and thus should not have been disclosed at trial.

The Appellate Division’s reversal based on improper admittance of testimony was challenged by the prosecution, arguing that no physician-patient relationship existed because Dr. Wechter’s examination was not for treatment purposes. The Court disagreed, stating that treatment by other hospital staff established such a relationship and that the conversation with Dr. Wechter was indeed for treatment purposes, making it privileged information under section 352 of the Civil Practice Act.


Conclusion Icon

The Court affirmed that Decina’s conduct constituted culpable negligence under section 1053-a of the Penal Law and upheld the lower court’s decision overruling the demurrer. However, it agreed with the Appellate Division that Dr. Wechter’s testimony should not have been admitted due to physician-patient privilege.

Key Takeaways

Takeaway Icon
  1. Individuals with known medical conditions that can impair their ability to drive may be held criminally negligent if they choose to drive and cause harm.
  2. The physician-patient privilege protects conversations necessary for medical diagnosis or treatment from being disclosed in court without consent.
  3. The presence of third parties such as police guards does not necessarily negate physician-patient privilege if they are not actively participating in or influencing the medical consultation.

Relevant FAQs of this case

What determines the criminal liability of an individual with a medical condition that could lead to unconsciousness while driving?

Criminal liability for an individual with such a medical condition hinges on their awareness of the risk and the voluntary undertaking of an activity, like driving, which could foreseeably harm others. If the individual is aware that their condition could cause unconsciousness and still decides to drive, they may be held criminally negligent for disregarding the safety of others.

  • For example: A person with diagnosed narcolepsy who has experienced sleep attacks while seated may be criminally negligent if they choose to drive, knowing they could fall asleep at the wheel.

How does patient-physician privilege apply when a patient discloses a medical condition in the presence of law enforcement?

Patient-physician privilege typically protects disclosures made by a patient to a physician when seeking medical care. The presence of law enforcement does not automatically negate this privilege unless they actively participate in the medical discussion. Essential treatment-related disclosures remain protected if law enforcement presence is incidental.

  • For example: If a detained suspect informs an attending physician about drug allergies in front of a police officer, this information should remain privileged since it’s vital for the suspect’s safe medical treatment.

When can an individual's knowledge of their medical impairment lead to the imposition of criminal penalties following an accident?

An individual’s prior knowledge of a medical impairment can result in criminal penalties if it can be proven that they consciously disregarded this knowledge by engaging in actions that posed a significant risk to public safety, leading to an accident.

  • For example: A driver knows that they experience severe vision impairment at night due to an untreated condition but chooses to drive after dark and causes an accident, this may be deemed criminally negligent as it shows a willful disregard for potential danger.
