People v. Luo
2017 Cal. App. LEXIS 940
Cal. Ct. App. 5th2017Background
- Dan Luo supervised a hillside residential construction project in Milpitas; excavation left a 12-foot unsupported dirt wall with an overhanging ledge.
- City inspector issued a Stop Work Notice to Luo on January 25, 2012 stating excavation without required shoring/consultation; Luo did not notify workers or obtain city approval.
- Luo instructed workers to continue and to put boards along the excavation so the owner would see progress.
- On January 26, 2012 the excavation collapsed, killing worker Raul Zapata.
- A grand jury indicted Luo for involuntary manslaughter (Pen. Code § 192(b)) and three counts of willful violation of occupational safety orders causing death (Lab. Code § 6425(a)); a jury convicted him on all counts and he was sentenced to two years county jail.
- On appeal Luo challenged sufficiency of evidence, various jury instructions, limits on cross-examination, notice/election, and the constitutionality of § 6425(a); the appellate court affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Sufficiency of evidence for involuntary manslaughter | Prosecution: evidence showed Luo supervised, ignored Stop Work Notice, directed work in dangerous area — criminal negligence supported conviction | Luo: needed expert testimony to establish duty/standard of care and breach; insufficient proof he violated Stop Work Notice | Affirmed — criminal negligence judged by ordinary-prudent-person standard; expert testimony not required; evidence sufficient. |
| Sufficiency of evidence for willful violation of safety orders (Lab. Code § 6425(a)) | Prosecution: regs require protective systems, inspections, barricades; expert linked noncompliance to cave-in; photos and body evidence show causation | Luo: expert testimony required to prove regulatory violation caused death; causation speculative | Affirmed — expert testimony and physical evidence supported causation and regulatory noncompliance. |
| Jury instructions (scope of “construction of a residence,” duty, inclusion of regs) | Prosecution: CALCRIM instructions correctly stated law; providing full regulations and summaries aided jury | Luo: trial court should have defined acts within "construction of a residence," instructed on specific duty, and not provided full regs without guidance | Affirmed — no sua sponte duty to further define phrase; ordinary-duty instruction adequate; giving full text of regulations and proper elements instruction not erroneous. |
| Notice / election of acts and unanimity | Prosecution: indictment and grand jury evidence provided adequate notice; only one discrete crime alleged | Luo: lacked fair notice of which specific acts supported criminal negligence; prosecution should have elected particular act | Affirmed — grand jury and discovery provided notice; election doctrine inapplicable where single discrete crime alleged; court also gave unanimity instruction. |
| Vagueness of Lab. Code § 6425(a) | State: statute clearly criminalizes willful violations by employers and supervisory employees | Luo: statute vague because underlying regs don’t state they apply to supervisors; risk of arbitrary enforcement | Affirmed — § 6425(a) text plainly notifies supervisory employees are within scope; statute not unconstitutionally vague. |
