What this does not show
These are statutes cited in the record's document where it charges, finds or alleges a violation, not necessarily proven ones. Dismissed and pending matters count as alleged. A release that names no section is not matched, so counts understate use of this provision. The plain-language meaning is a summary, not legal advice.
