Environmental lawsuits can be complex and costly. Learn how to use motions to dismiss to challenge standing, jurisdiction, and legal deficiencies—before the case ever reaches discovery.

Motions to dismiss are powerful tools in environmental litigation, where disputes often involve intricate regulations, scientific data, and sweeping legal theories. Defendants—whether businesses, government agencies, or individuals—can strategically use motions to dismiss to challenge procedural defects, jurisdictional gaps, or statutory noncompliance at the earliest stages.

This guide explores how to craft an effective motion to dismiss in environmental cases, common grounds for dismissal, and real-world examples of successful defenses.

1. Common Grounds for Dismissing Environmental Lawsuits

A. Lack of Standing (Rule 12(b)(1))

Environmental plaintiffs must establish:

• Injury in Fact: Concrete, particularized harm.

• Causation: Harm is directly traceable to the defendant’s actions.

• Redressability: A favorable court ruling would remedy the injury.

Example:
If an environmental group sues over alleged pollution but fails to show harm to its members, the defendant can seek dismissal for lack of standing.

Case Law:
Lujan v. Defenders of Wildlife (1992) established strict standing requirements in environmental lawsuits.

B. Lack of Jurisdiction (Rule 12(b)(1))

Courts may lack subject matter jurisdiction if:

• Claims are improperly filed in state vs. federal court.

• Plaintiffs fail to exhaust administrative remedies before suing.

Example:
A plaintiff improperly brings a Clean Water Act claim in state court without exhausting EPA procedures, opening the door to dismissal.

C. Failure to State a Claim (Rule 12(b)(6))

Defendants can argue that:

• Allegations are vague or conclusory.

• No specific legal violations are cited.

• Plaintiffs misinterpret environmental statutes.

Example:
A lawsuit alleging "harm to the environment" without citing a specific statutory breach may be dismissed for failure to state a claim.

D. Statute of Limitations

Environmental claims are subject to strict filing deadlines:

• Clean Water Act: 5 years.

• CERCLA (Superfund): Varies based on discovery of contamination.

Example:
If plaintiffs sue 15 years after a pollution event with no continuing violations, defendants can argue the claims are time-barred.

E. Political Question Doctrine

Some environmental disputes involve non-justiciable political questions, such as policy decisions reserved for Congress or regulatory agencies.

Example:
A lawsuit seeking to force adoption of a national climate policy may be dismissed because courts defer such issues to legislative bodies.

2. Strategies for Drafting an Effective Motion to Dismiss

✅ Use Clear and Precise Legal Arguments

• Cite specific statutes, procedural rules, and binding case law.

• Demonstrate why allegations do not meet legal standards.

Example:
✅ "Under Bell Atl. Corp. v. Twombly, 550 U.S. 544 (2007), plaintiffs must plead sufficient factual matter to state a plausible claim for relief. Here, plaintiffs allege pollution without identifying a permit violation or statutory breach."

✅ Focus on Complaint Deficiencies

• Identify missing elements critical to statutory claims.

• Show how even assuming all facts as true, no legal remedy is available.

✅ Leverage Jurisdictional Arguments

• Push for dismissal or transfer when federal preemption or sovereign immunity applies.

• Force plaintiffs into less favorable forums when possible.

Example:
A city sued under CERCLA may argue sovereign immunity for actions taken as a regulator, not as a polluter.

3. Examples of Successful Motions to Dismiss in Environmental Cases

1️⃣ Native Village of Kivalina v. ExxonMobil Corp. (2012)

• Issue: Village sued oil companies for climate change damages.

• Defense: Raised political question doctrine.

• Outcome: Dismissed—court ruled that climate regulation is for Congress, not courts.

2️⃣ Center for Biological Diversity v. U.S. EPA (2018)

• Issue: Environmental groups sued EPA for pesticide regulation inaction.

• Defense: Plaintiffs failed to exhaust administrative remedies.

• Outcome: Dismissed—plaintiffs needed to first petition the EPA before filing suit.

4. Final Thoughts

Motions to dismiss are critical tools in environmental litigation for defendants seeking early resolution. They allow parties to:

✔ Challenge standing, jurisdiction, and procedural missteps.
✔ Argue failure to state a valid legal claim.
✔ Invoke statutes of limitations and political question defenses.
✔ Avoid costly and burdensome discovery phases.

By focusing on clear statutory grounds, crafting precise legal arguments, and leveraging jurisdictional defenses, defendants can effectively minimize risk and protect their interests early in litigation.
