MS HB1243

Creates Mississippi Code Section 97-25-59 establishing criminal penalties for impeding critical infrastructure facilities, including pipelines, power plants, telecommunications towers, water treatment facilities, and 16 other categories of essential infrastructure.

Defines "impeding critical infrastructure" as intentionally or knowingly blocking operations or legal access to critical facilities, or damaging/destroying their equipment; punishable as a misdemeanor (up to 6 months imprisonment and $1,000 fine) if damage costs less than $1,000, or as a felony (up to 7 years imprisonment and $10,000 fine) if damage costs $1,000 or more.

Establishes "critical infrastructure trespass" as a misdemeanor (up to 1 year imprisonment and $1,000 fine) for unauthorized entry onto critical infrastructure facilities or construction sites, including entry using false identification or after being notified to depart.

Allows organizations that aid or abet critical infrastructure crimes to be fined up to $100,000, and permits facilities to pursue civil damages including lost profits; permits aggregating damage costs from a single continuing course of conduct into one violation.

Provides exemptions for property owners conducting authorized activities, persons engaged in lawful regulatory processes, and protects public demonstrations and constitutional free speech and assembly rights.
