Facts

Warner-Lambert manufactured Freshen-Up gum using magnesium stearate dust and liquid nitrogen in a process that created ambient and settled dust around Uniplast machines. Defendants had been advised months earlier that the dust condition in the production area presented an explosion hazard and that the concentration was above the lower explosion level, but the dust remained while the company worked toward eventually eliminating magnesium stearate from the process. On November 21, 1976, while one Uniplast machine was operating and employees were sweeping and airhosing accumulated dust, a small explosion occurred at the machine followed almost immediately by a much larger explosion and fire that killed six employees. The People's proof of what actually triggered the initial explosion was only hypothetical, including theories of mechanical sparking or ignition involving liquid oxygen formed through liquefaction.

Issue

Whether Grand Jury evidence that defendants knew of a general explosion risk from ambient magnesium stearate dust was legally sufficient to support charges of reckless manslaughter or criminally negligent homicide when the actual immediate triggering cause of the explosion was not shown to have been foreseen or foreseeable. Put differently, can criminal liability rest on a broad known risk plus but-for causation alone?

Rule

To establish manslaughter in the second degree or criminally negligent homicide, the People must prove not only a substantial and unjustifiable risk and causation, but also that the defendant's conduct was a sufficiently direct cause of death under criminal-law standards. Criminal liability cannot be based solely on but-for causation or on awareness of a broad, undifferentiated danger; the actual immediate triggering cause of death must have been foreseen or reasonably foreseeable.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In Toledo, Ohio, managers at Lakefront Solvents, Inc. learned that fine resin dust in a mixing room created a serious explosion hazard if ignited. Weeks later, an employee was killed when the dust exploded after a rare seismic tremor caused a ceiling light to fall, shatter, and spark; investigators found no evidence the managers had reason to anticipate tremors or falling fixtures.

Assuming the evidence otherwise shows awareness of the general dust hazard, is a reckless manslaughter charge most likely sustainable?

Explanation. The majority required more than proof of a broad, undifferentiated danger plus but-for causation. For reckless manslaughter or criminally negligent homicide, the defendant's conduct must be a sufficiently direct criminal cause of death, and the actual immediate triggering cause must have been foreseen or foreseeable. Here, the tremor-caused falling fixture was not shown foreseeable, so criminal liability is not established on these facts.
