• States with laws (selected): Texas, Oklahoma, Louisiana, North Dakota, South Dakota, Iowa, Tennessee, West Virginia, Kentucky, Mississippi, Missouri, Georgia, Indiana, Arkansas, Montana, Wisconsin, Wyoming, Alabama, and others

What These Laws Do

Critical infrastructure protection laws create a new category of enhanced criminal penalty for protests and trespass near designated "critical infrastructure." Common provisions:

• Felony trespass — Entering or remaining on "critical infrastructure" (pipelines, oil and gas facilities, refineries, power plants, dams, water treatment facilities, chemical plants, and in some states, data centers or rail lines) is upgraded from misdemeanor trespass to a felony, typically a 2nd or 3rd-degree felony with 1–10 year sentences.
• Enhanced penalties for "tampering" — Any act that interferes with the operation of a critical infrastructure facility — including blocking a road or access point near the facility — carries significantly elevated penalties.
• Organizational liability — Several laws (notably Texas SB 1978 and Louisiana HB 197) impose liability on organizations that "conspire with" or "direct" the trespass, exposing nonprofits, advocacy groups, and legal funds to civil damages or felony charges for providing support to protesters.
• Broad facility definitions — "Critical infrastructure" is defined so broadly in most states that ordinary farms, irrigation systems, cell towers, or industrial facilities can qualify, effectively creating felony liability for trespass anywhere near industrial property.

Origin: The Dakota Access Pipeline Template

The legislative wave was directly triggered by the Standing Rock Sioux Tribe's 2016–2017 resistance to the Dakota Access Pipeline. The ALEC-aligned Energy Citizens campaign circulated model legislation ("Critical Infrastructure Protection Act") following Standing Rock. At least 17 states adopted versions of this model within three years, with more following through 2026.

The legislation was drafted with input from fossil fuel industry groups and state legislative networks linked to ALEC. Internal documents obtained by journalists showed coordination between pipeline companies and state legislators in the drafting process.

States With Most Aggressive Laws

Texas HB 3557 / SB 1978 (2021): Creates felony liability for organizations that provide "material support" to anyone who trespasses at a critical infrastructure facility. The phrase "material support" mirrors post-9/11 terrorism law language and can be read to encompass bail funds, legal representation, transportation, or food for protesters. Violating organizations face fines up to $500,000.

Louisiana HB 197 (2018): One of the first state laws to specifically include organizational liability. Amended in 2020 to also cover protests at "natural gas pipelines" and "carbon capture facilities."

Oklahoma SB 401 (2017): First major state law in the wave; signed by Governor Stitt. Creates felony trespass at oil and gas facilities and pipelines. Sets a template followed by dozens of states.

South Dakota HB 1117 / "Riot Boosting" Laws (2019): Went further by criminalizing "riot boosting" — the act of directing, advising, encouraging, or soliciting others to commit riot or property damage during a protest. Was struck down in part by a federal court as unconstitutionally vague.

Why Critics Oppose Them

• Designed to suppress specific viewpoints — The legislative history of these laws — ALEC model language, fossil fuel industry involvement, explicit response to pipeline protests — shows they were engineered to chill climate and Indigenous rights activism, not to protect infrastructure from actual sabotage (for which federal law already provides severe penalties).
• Disproportionate to actual threat — A person standing near a pipeline faces felony charges, while the same act on non-designated property is a misdemeanor. The disparate treatment targets the political context of the protest, not the trespass conduct itself.
• Organizational liability chills support networks — Exposing advocacy groups to felony charges for supporting protesters destroys the civil society infrastructure that historically supports protest movements — legal aid, bail funds, communication, transportation.
• Overbroad definitions — "Critical infrastructure" definitions broad enough to cover farms, cell towers, and rail lines turn ordinary trespass into a potential felony anywhere protesters go.
• Exporting the model — Because most states used the same ALEC model bill, passing one state version creates national momentum for the same restrictions everywhere.

Constitutional Concerns

• 1st Amendment (freedom of assembly) — Enhanced penalties for conduct at politically charged protest locations selectively burden protest activity.
• 1st Amendment (freedom of association) — Organizational liability for supporting protesters threatens civil society groups' ability to operate.
• 1st Amendment (chilling effect) — Felony exposure for ambiguous conduct near broadly defined facilities effectively deters lawful protest activity.
• 5th Amendment (void for vagueness) — Overbroad definitions of "critical infrastructure" and "interference" fail to provide fair notice of what is prohibited.
• Equal protection — Laws drafted in response to one political viewpoint (pipeline opposition) that impose no equivalent burden on other forms of trespass.

Key Votes to Screen

For each state, look up the specific critical infrastructure bill vote. In most states these passed along party lines in Republican-controlled legislatures. A YES vote identifies a legislator who voted to impose felony charges on climate and Indigenous rights activists for activities that would be misdemeanors for any other trespasser.

Why This Matters for We The Citizens

Critical infrastructure anti-protest laws are the domestic application of anti-terrorism infrastructure developed after 9/11, re-aimed at environmental and civil rights protest. They represent a multi-state coordinated campaign to raise the cost of organized dissent in the energy sector to the point where it becomes practically impossible.
