    Facts

    Welanksy owned a night club in Boston. He typically spent his evenings at the club, inspecting the premises and superintending the business. On November 16, 1942, he became ill was had to be hospitalized until December 11, 1942. While in the hospital, he did not worry much about the club, because he “knew it would be all right” and that “the same system he had would continue” during his absence. There was no evidence of any act, omission, or condition at the club during his time away that was not regular practice while he was there.

    On November 28, 1942, nearly a thousand people were at the club when an artificial tree caught on an employee lighting an electric light bulb that was near or in the coconut husks of the tree. The fire spread rapidly throughout the club and the panic stricken crowd rushed and paused in every direction, screaming, overturning tables, and throwing chairs in their attempts to escape. Many patrons and employees died.

    Welanksy was indicted for involuntary manslaughter. Among other things, it alleged that he was reckless by failing to prevent defective wiring, installing flammable decorations, and failing to have sufficient proper exits and fire doors. He was found guilty. He appealed, arguing that he was not reckless because he did not intend to harm anyone.

    0 of 3 Questions answered correctly.

    Results

    Quiz complete. Results are being recorded.
    Q.1 - Which statement most precisely captures the Welansky court’s mens rea for involuntary manslaughter by omission in a public-accommodation setting?
    Start Your Free Trial or Log in.
    Incorrect. This is wrong because precise-mechanism foresight is unnecessary; a high likelihood of serious harm suffices.
    Incorrect. This is wrong because civil negligence is insufficient for criminal recklessness.
    Incorrect. This is wrong because Welansky does not impose strict liability.
    Correct! The court defined wanton or reckless indifference as knowledge (actual or chargeable) of facts making lethal risk obvious to a reasonable person, coupled with failure to act despite a legal duty. This hybrid standard allows mens rea to attach to omissions where danger is grave and foreseeable in a public venue.
    Q.2 - On which doctrinal foundation does Welansky most squarely ground criminal liability for an absentee owner when deaths result from fire-exacerbating conditions at the venue?
    Start Your Free Trial or Log in.
    Incorrect. This is wrong because mere vicarious liability is not the basis; the owner’s independent duty is.
    Correct! Liability turns on a nondelegable duty stemming from control of premises: the owner’s omission in remedying known, lethal hazards sustains recklessness even if absent. The duty’s persistence supplies the actus reus via omission and the culpability via conscious (or chargeable) disregard of grave risks.
    Incorrect. This is wrong because the case does not convert manslaughter to murder via constructive malice.
    Incorrect. This is wrong because the Commonwealth must still prove risk appreciation and causal linkage.
    Q.3 - Assume a due-process challenge that the Welansky standard is void for vagueness when applied to omission-based manslaughter. Which response most accurately reflects the decision’s constitutional footing?
    Start Your Free Trial or Log in.
    Correct! Welansky relies on entrenched common-law vocabulary—wanton/reckless—tethered to objective foreseeability and a concrete legal duty, which provides constitutionally adequate notice. The standard channels discretion by requiring proof of grave risk under conditions a reasonable actor would recognize.
    Incorrect. This is wrong because due process does not demand exhaustive codification of every omission.
    Incorrect. This is wrong because precise-defect knowledge is unnecessary; awareness of lethal risk suffices.
    Incorrect. This is wrong because regulatory overlap does not render the criminal standard vague.
