Between 1964 and 1992, Texaco operated oil drilling operations in Ecuador's Lago Agrio region that dumped approximately 30 billion gallons of toxic wastewater and spilled 16.8 million gallons of crude oil into the Amazon rainforest. When indigenous communities and settlers filed suit in 2003, the resulting legal battle produced a $9.5 billion Ecuadorian judgment, allegations of judicial corruption, a RICO counterclaim, international arbitration rulings, and the disbarment and house arrest of the plaintiffs' lead attorney. The case remains one of the most extensively documented and fiercely contested environmental litigation sagas in corporate history.
Between 1964 and 1992, Texaco Inc. operated petroleum extraction operations across approximately 1.5 million acres in Ecuador's northeastern Amazon region, known as the Lago Agrio or Sucumbíos concession. The company drilled 339 wells and extracted approximately 1.4 billion barrels of crude oil in partnership with Ecuador's state oil company — first Gulf Oil, then PetroEcuador after 1974.
The environmental toll was extraordinary. According to technical assessments conducted by multiple independent consulting firms, Texaco's operations discharged an estimated 30 billion gallons of toxic formation water — the byproduct liquid that comes up with crude oil during extraction — directly into Amazonian rivers, streams, and unlined earthen waste pits. The company also spilled approximately 16.8 million gallons of crude oil through pipeline ruptures, well blowouts, and storage tank failures.
Formation water contains benzene, toluene, xylene, polycyclic aromatic hydrocarbons, heavy metals including mercury, cadmium, and lead, and naturally occurring radioactive materials. In Texaco's U.S. operations during the same period, Environmental Protection Agency regulations required re-injection of formation water into deep underground wells to prevent surface contamination. In Ecuador, where no such regulations existed in the 1960s and 1970s, Texaco designed a disposal system that discharged formation water directly into surface waters or dumped it into unlined pits where it would seep into groundwater.
Internal Texaco memoranda from 1972 acknowledged that re-injection technology was feasible in Ecuador. One engineering memo noted the cost differential: re-injection infrastructure would require capital investment of approximately $5 per barrel of oil produced, while direct discharge cost pennies. Over 1.4 billion barrels, the company saved an estimated $7 billion by avoiding re-injection costs.
The first lawsuit was filed in U.S. federal court in 1993. A class of approximately 30,000 Ecuadorian plaintiffs — indigenous Cofán, Siona, and Secoya communities, along with mestizo settlers — sued Texaco in the Southern District of New York, where the company was headquartered. The complaint alleged that Texaco's waste disposal practices constituted negligence, nuisance, trespass, and violations of international environmental law.
Texaco moved to dismiss on grounds of forum non conveniens — arguing that Ecuador, not the United States, was the proper venue for the case. The company's lawyers filed declarations stating that Ecuador's courts were adequate and that Texaco would submit to jurisdiction there. After nine years of procedural litigation, the Second Circuit Court of Appeals agreed in 2002, dismissing the case on condition that Texaco consent to jurisdiction in Ecuador.
Plaintiffs refiled in Ecuador in 2003 as Aguinda v. ChevronTexaco. By that time, Chevron had acquired Texaco in a $36 billion merger. The Ecuadorian case proceeded under civil law procedures that differ substantially from U.S. litigation: no jury, no extensive pre-trial discovery, judicial site inspections, and court-appointed technical experts.
"The ends do not justify the means. There is no 'Robin Hood' defense to illegal and wrongful conduct. And the defendants' 'this-is-the-way-it-is-done-in-Ecuador' excuses — actually a remarkable insult to the people of Ecuador — do not help them."
Judge Lewis Kaplan — Chevron Corp. v. Donziger, 2014In 2007, Judge Nicolás Zambrano appointed engineer Richard Cabrera as an independent court expert to assess environmental damage. Over two years, Cabrera's team conducted soil and water testing at well sites, waste pits, and residential areas throughout the former concession. The resulting report documented extensive contamination and calculated damages of $27.3 billion based on estimated remediation costs.
Chevron immediately attacked Cabrera's methodology and independence. The company obtained outtakes from Crude, a documentary film about the case directed by Joe Berlinger. The footage showed meetings between Cabrera and the plaintiffs' consultants from Stratus Consulting that Chevron characterized as evidence the report was not independent but rather ghostwritten by the plaintiffs' team.
On February 14, 2011, Judge Zambrano issued a 188-page judgment finding Chevron liable for environmental damage. The court awarded $8.6 billion in compensatory damages for remediation, $700 million for health programs, and included a provision doubling the total to $18.6 billion if Chevron did not issue a public apology within 14 days. Chevron refused to apologize. Ecuador's appellate courts later struck the doubling provision, reducing the final judgment to $9.5 billion.
Chevron announced it would not pay "a single dime" and characterized the judgment as "illegitimate and unenforceable." The company had withdrawn all assets from Ecuador years earlier, leaving nothing in the country that plaintiffs could seize to satisfy the judgment.
Rather than defend the judgment's enforcement, Chevron went on offense. In 2011, the company filed a civil RICO lawsuit in U.S. federal court alleging that Steven Donziger and his legal team obtained the Ecuadorian judgment through a pattern of racketeering activity including bribery, fraud, money laundering, witness tampering, and obstruction of justice.
The case was assigned to Judge Lewis Kaplan of the Southern District of New York. After a six-week bench trial in 2013, Kaplan issued a 485-page opinion in March 2014 finding that Donziger and his team had engaged in a fraudulent scheme. The ruling relied heavily on testimony from Alberto Guerra, a former Ecuadorian judge who had worked briefly in Judge Zambrano's court.
Guerra testified that Judge Zambrano agreed to issue a judgment favorable to the plaintiffs in exchange for $500,000, that the judgment was ghostwritten by Donziger's legal team and delivered to Zambrano on a USB drive, and that Guerra personally participated in meetings where these arrangements were discussed. His testimony became the evidentiary foundation for Judge Kaplan's fraud findings and for later international arbitration rulings.
Under cross-examination, problematic elements of Guerra's testimony emerged. He admitted that when first approached by Chevron investigators, he denied any knowledge of corruption. His story evolved over multiple interviews. He acknowledged lying under oath in Ecuadorian court proceedings. And he confirmed that Chevron had paid him approximately $2 million, relocated his family to the United States, paid for housing and living expenses, covered his children's private school tuition, and provided immigration assistance.
Legal ethicists raised concerns about whether paying a witness millions of dollars while he is testifying against your opponent constitutes witness-buying. Chevron maintained the payments were legitimate witness protection compensation. Judge Kaplan acknowledged the payments created "legitimate questions" about credibility but found Guerra's core testimony credible, noting it was corroborated by documentary evidence including the Crude film outtakes.
Judge Kaplan's March 2014 ruling found that the Ecuadorian judgment was "obtained through corrupt means" and permanently enjoined Donziger from profiting from or enforcing the judgment in the United States. The ruling acknowledged that "there is no doubt that Texaco caused significant environmental harm in the Oriente region" but concluded that fraud in obtaining the judgment invalidated it regardless of the underlying merits.
Crucially, Kaplan's ruling applied only to enforcement in the United States under principles of comity — the doctrine that U.S. courts will recognize foreign judgments unless they were obtained through processes fundamentally at odds with U.S. due process standards. The ruling did not invalidate the judgment in Ecuador or other jurisdictions.
Plaintiffs attempted to enforce the judgment in Canada, Brazil, Argentina, and other countries where Chevron held assets. Chevron successfully blocked enforcement in each jurisdiction, with courts citing either Judge Kaplan's fraud findings or rulings from international arbitration tribunals.
In 2009, Chevron filed for international arbitration under the U.S.-Ecuador Bilateral Investment Treaty (BIT), arguing that Ecuador's judicial system had denied the company fair and equitable treatment in violation of treaty obligations. The case was administered by the Permanent Court of Arbitration in The Hague.
The three-member arbitration panel — comprising one arbitrator selected by Chevron, one by Ecuador, and one by mutual agreement — issued interim orders in 2012 directing Ecuador to "take all measures at its disposal" to suspend enforcement of the judgment. In August 2018, the tribunal issued its final award finding that Ecuador violated the BIT.
The tribunal did not award Chevron monetary damages but ordered Ecuador to "take all measures necessary to suspend or cause to be suspended the enforcement and recognition within and without Ecuador" of the judgment, and to indemnify Chevron for any amounts it paid to satisfy the judgment anywhere in the world.
Legal scholars noted the extraordinary nature of this ruling: an international arbitration tribunal effectively ordering a sovereign nation's court system to overturn or nullify its own final judgment. The decision represented an expansion of investment treaty protections that raised fundamental questions about the relationship between international commercial law and domestic judicial sovereignty.
In 2019, Judge Kaplan took an unprecedented step. After Donziger refused to comply with an order to turn over his electronic devices and privileged attorney-client communications to Chevron's lawyers — citing ethical obligations to protect client confidences — Kaplan held him in criminal contempt of court.
The U.S. Attorney's Office for the Southern District of New York reviewed the matter and declined to prosecute. In response, Judge Kaplan appointed a private law firm to prosecute the contempt charge. The firm assigned to the case, Seward & Kissel, included attorneys who had previously worked at Gibson, Dunn & Crutcher — Chevron's primary outside counsel in the Ecuador litigation.
Donziger was placed under home detention in August 2019. His ankle monitor was not removed until April 2022, a total of 993 days — the longest pre-trial home detention for a misdemeanor charge in recorded U.S. history. In October 2021, after a bench trial before Judge Loretta Preska, Donziger was convicted and sentenced to the maximum six months in federal prison.
"We are concerned that the criminal prosecution against Mr. Donziger may constitute retaliation for his work as a lawyer and environmental defender, as well as an attempt to dissuade other lawyers and environmental activists from working on cases similar to the Chevron case."
UN Special Rapporteurs — Communication to U.S. Government, July 2021The case attracted international attention. Three UN Special Rapporteurs issued a formal communication expressing concern that prosecuting criminal contempt through a private law firm with connections to the opposing party violated fundamental principles of judicial independence and due process. Over 475 lawyers, including 29 Nobel laureates and former U.S. Attorney General Ramsey Clark, filed amicus briefs arguing the prosecution was irregular.
In 2020, New York's Appellate Division suspended Donziger's law license based on Judge Kaplan's fraud findings. The suspension was made permanent in 2021, effectively ending his legal career.
Certain facts are not disputed. Texaco's operations in Ecuador between 1964 and 1992 discharged tens of billions of gallons of toxic waste into the Amazon. Chevron's own environmental consultants acknowledge contamination exists, though they dispute its extent and current toxicity levels. Health studies in affected communities document elevated cancer rates compared to control populations.
The 1998 release agreement between Texaco and Ecuador is also undisputed — though its legal effect is contested. Chevron argues the release bars all claims. Plaintiffs argue it covered only the 162 sites Texaco remediated and did not release liability for the hundreds of sites left untouched, and that the release was between Texaco and the government, not between Texaco and private parties.
The contested territory lies in the conduct of the litigation itself. Judge Kaplan found, based on Guerra's testimony and documentary evidence including the Crude outtakes, that Donziger and his team ghostwrote the Cabrera expert report, bribed Judge Zambrano, coerced witnesses, and fabricated evidence. These findings have been adopted by international arbitration tribunals and cited by courts in multiple countries blocking enforcement.
Donziger and the plaintiffs maintain that Guerra's testimony was purchased, that the Crude footage was taken out of context and shows ordinary litigation work product, that no Ecuadorian authority has found evidence of judicial corruption, and that the fraud allegations are themselves part of a corporate strategy to evade a legitimate environmental judgment through legal asymmetry — using the resources of the world's wealthiest legal systems to override the judgments of its poorest.
The Chevron-Ecuador case sits within a broader pattern documented by international law scholars. Multinational corporations facing adverse judgments in developing countries increasingly pursue parallel litigation in U.S. or European courts attacking the foreign judgment's legitimacy, file investment treaty arbitrations claiming denial of justice, and use discovery procedures in wealthy jurisdictions to obtain evidence that can be reframed as proof of corruption.
The strategy works because of asymmetry. Chevron has spent an estimated $2 billion on the Ecuador litigation. The plaintiffs' entire legal budget over 28 years was approximately $15 million. Chevron employed 60 law firms across multiple continents. The plaintiffs had a small team working largely on contingency.
Legal scholars including Professor Judith Kimerling of CUNY Law School and Professor Burt Neuborne of NYU Law School have argued that the case represents a form of "legal colonialism" — where the legal infrastructure of wealthy countries is deployed to nullify environmental accountability judgments issued by developing nations whose environmental regulations corporations had exploited for profit.
Others, including scholars who filed amicus briefs supporting Chevron, argue that evidence of corruption in foreign judicial proceedings must be taken seriously regardless of the underlying environmental harm, and that enforcing fraudulently obtained judgments would undermine international comity and rule of law principles.
As of 2024, the situation remains largely frozen. The $9.5 billion judgment stands as valid in Ecuador but has been blocked from enforcement in every jurisdiction where plaintiffs have attempted collection. Chevron has no assets in Ecuador. International arbitration awards prohibit Ecuador from allowing enforcement.
The contamination in the Lago Agrio region continues. While some remediation has occurred — conducted by PetroEcuador and by Texaco under the 1998 agreement — most of the 880 documented waste pits remain untouched. Communities continue to report health effects. Cancer rates in the affected region remain elevated compared to national averages.
Steven Donziger was released from prison in April 2022 after serving his six-month sentence. He remains disbarred. His conviction has been upheld on appeal. International human rights organizations including Amnesty International have called him a human rights defender subjected to judicial retaliation.
Several questions remain unresolved and contested:
Was the Ecuadorian judgment obtained through fraud? Judge Kaplan found yes, based substantially on paid witness testimony. Ecuadorian courts and international legal observers have questioned whether Guerra's incentivized testimony meets reliability standards and whether coordination between lawyers and experts constitutes fraud or normal litigation.
Does the 1998 release bar claims? Chevron argues it released all liability. Plaintiffs note the release was between Texaco and the government, covered only specific sites, and under Ecuadorian law cannot bar private tort claims.
Should international investment treaties allow corporations to override domestic court judgments? The arbitration rulings represent an assertion of international commercial law supremacy over domestic judicial sovereignty that many legal scholars find troubling, particularly in environmental cases.
Can a private law firm with financial ties to the opposing party ethically prosecute criminal contempt? Constitutional law scholars have argued the Donziger prosecution violated separation of powers. Courts upheld it as within judicial contempt authority.
What is not contested is the underlying environmental reality: one of the worst oil-related contaminations in history, affecting tens of thousands of people, remains largely unremediated three decades after operations ceased. The legal battle over who should pay for cleanup has now lasted longer than the contamination itself.
