For decades, private citizens and advocacy groups have served as watchdogs over America’s environmental laws, filing lawsuits against polluters when government agencies fall short. This legal tool, known as a ‘citizen suit,’ has been a cornerstone of environmental enforcement since the 1970s. But the Trump administration moved aggressively to limit these suits, arguing they burden businesses and create frivolous litigation. As the Biden administration reverses some of these changes, the debate over who gets to enforce environmental protections—and how—remains as contentious as ever.
The Citizen Suit: A Backstop for Environmental Enforcement
Citizen suit provisions are embedded in major U.S. environmental laws, including the Clean Air Act, Clean Water Act, Endangered Species Act, and Resource Conservation and Recovery Act. These provisions allow individuals and non-governmental organizations (NGOs) to file lawsuits against violators when government agencies fail to act. The idea, rooted in the bipartisan environmental legislation of the 1970s, was simple: agencies have limited resources and can be subject to political pressure, so citizens should have a legal avenue to ensure the laws are enforced.
But these suits are not free-for-alls. To file a citizen suit, a plaintiff must demonstrate concrete injury—such as being harmed by polluted water or air—and provide a 60-day notice to the EPA, the state, and the alleged violator. If the government is already ‘diligently prosecuting’ the violation, the suit cannot proceed. These procedural hurdles ensure that citizen suits are a last resort, not a first strike.
The Trump Administration’s Moves
Starting in 2019, the Environmental Protection Agency (EPA) under Administrator Andrew Wheeler proposed and finalized rules that narrowed the scope of citizen suits under the Clean Water Act and Clean Air Act. One key change restricted the ability of third parties to sue over permit violations, making it harder for communities to challenge pollution that slips through the cracks of permit compliance.
The Department of Justice (DOJ) also issued guidance discouraging the use of settlement payments to third-party groups in environmental enforcement cases. These payments, often part of consent decrees, had been used to fund community projects like water quality monitoring or habitat restoration. The administration argued that such payments were a form of ‘extortion’ that diverted money from polluters to advocacy groups.
Beyond these specific actions, the administration pursued a broader deregulatory agenda, including executive orders to reduce ‘unnecessary’ litigation and a push to appoint judges and agency officials skeptical of broad standing for environmental groups. These efforts accelerated in 2019–2020, with several rules finalized in the final year of the first Trump term.
The Rationale: Curbing ‘Frivolous’ Lawsuits
The administration and industry groups like the American Petroleum Institute and the U.S. Chamber of Commerce framed these changes as a necessary check on ‘trial lawyer-driven’ groups that abuse the system. They argued that citizen suits create uncertainty for businesses, duplicate government enforcement, and burden the courts with frivolous cases. For them, restricting these suits was part of a broader effort to reduce regulatory overreach and boost economic growth.
The Backlash: A Threat to Accountability
Environmental and public health groups, including the Sierra Club, Earthjustice, and the Natural Resources Defense Council, countered that citizen suits are a critical backstop when agencies fail to enforce the law. They argued that restricting these suits leaves communities—especially low-income and minority communities—without recourse when polluters violate the law. These groups have led legal challenges against the administration’s rules, and many have been successful in court.
State governments were divided. California and New York opposed the restrictions, arguing they undermine cooperative federalism, while states with strong fossil fuel industries supported the limits. Legal scholars have weighed in on both sides, debating whether citizen suits represent a legitimate check on executive discretion or an unconstitutional delegation of enforcement authority.
The Biden Reversal and the Ongoing Debate
The Biden administration has reversed several of the Trump-era rules, restoring some citizen suit provisions. However, the legal and policy debates continue. The issue is not just about who can sue, but about the fundamental question of how environmental laws are enforced in a system where government resources are limited and political winds shift.
Citizen suits have driven major cleanups, from forcing action on polluted waterways to protecting endangered species. They have also pressured agencies to meet statutory deadlines. As the debate continues, the role of citizens in environmental enforcement remains a vital—and contested—part of America’s environmental governance.
The Trump administration’s efforts to curb citizen suits were a significant chapter in the ongoing battle over environmental enforcement. While the Biden administration has reversed some of these changes, the debate over the proper role of citizens in holding polluters accountable is far from settled. As communities continue to face environmental challenges, the question of who has the power to enforce the law—and how—will remain central to the future of environmental protection in the United States.
Summary
- Citizen suits allow private citizens and NGOs to sue polluters when government agencies fail to enforce environmental laws.
- The Trump administration moved to restrict these suits through EPA rulemaking, DOJ guidance, and judicial appointments.
- Proponents argued the restrictions curb frivolous litigation and regulatory overreach, while opponents saw them as a threat to accountability.
- The Biden administration has reversed some of these changes, but the legal and policy debates continue.
- The outcome will shape how environmental laws are enforced and who holds polluters accountable.
