Chile’s Marathon SQM Case Ends in a 4,356-Page Acquittal
Chile · Justice
Key Facts
- Full acquittal All eight defendants, including politicians Pablo Longueira and Marco Enríquez-Ominami and former SQM general manager Patricio Contesse, were cleared on October 22, 2025.
- Massive ruling The written judgment runs 4,356 pages — so large it reportedly caused upload problems in the judiciary’s own computer systems due to file size and signature-processing issues.
- Appeal window Chile’s Public Ministry (prosecutors) has 30 days from formal notification to decide whether to file a recurso de nulidad (annulment appeal).
- Case origins The investigation into alleged illegal campaign financing began in 2014 and dragged on for over a decade.
- Not about lithium Despite SQM’s global profile as a lithium miner, this criminal case concerns political funding, not mining contracts, Corfo, or Tianqi.
- Notification delay The written sentence was formally notified only after the October acquittal, with the court struggling to finalize and deliver the document.
The real story here is not guilt or innocence, but how a single corporate political-financing scandal can consume a decade of Chile’s legal system — and what that means for anyone watching how the country holds power to account.
If you have followed Chile’s business or political scene, you know SQM. Lithium made it a global star, but the company was also central to a long criminal case.
The written judgment is finally out. The saga may not be over yet.
The ruling is a 4,356-page document from Santiago’s 3rd Oral Criminal Court. It was formally notified after the October 22, 2025 acquittal of all eight defendants.
Prosecutors are still deciding whether to appeal. Legal uncertainty could stretch even further.
What the SQM case ruling actually says
The written judgment is the formal record of the court’s decision. It clears everyone involved.
That includes Pablo Longueira, a former presidential candidate and minister. It also covers Marco Enríquez-Ominami, a former congressman and three-time presidential hopeful.
Patricio Contesse, SQM’s former general manager, is included too.
The court found no criminal liability for the alleged illegal campaign financing. That financing triggered the investigation back in 2014.
The document is over four thousand pages. Its sheer size made the notification process a small ordeal.
Reports indicate the judiciary had trouble uploading the file. Its size and signature-processing glitches caused the issue.
That is a fitting end to a case marked by delays. Procedural battles and an endless paper trail defined it from the start.

Why the appeal window matters now
The Public Ministry, Chile’s prosecutorial body, has not closed the door. It said it is reviewing the sentence to decide on a recurso de nulidad.
That is an annulment appeal challenging the trial’s legal validity, not the facts. The filing window is 30 days from notification.
A decision is expected within weeks. For the defendants, the acquittal is a full stop — for now.
An annulment appeal could reopen the case. It would go to a higher court and potentially force a retrial.
That would extend a legal saga that already outlasted two Chilean presidential terms. It has tested public patience.
If prosecutors drop the matter, the case ends quietly. If they appeal, the political and legal noise resumes.
The bigger picture for Chile’s political finance rules
This case is not about lithium. Keep that separate.
SQM is a major global producer of the metal. Its contracts with Corfo and shareholder disputes with Tianqi have made headlines for years.
The criminal case was always about something else. It concerned how money flowed into political campaigns.
The question was whether that flow broke the law. The investigation emerged from a broader scandal over corporate donations to politicians.
That practice was later restricted by law. For a reader living in or invested in Latin America, this matters.
It is a rare, concrete test of how courts handle white-collar political finance cases. A decade-long prosecution ending in full acquittal sends a signal.
That signal may be about weak evidence or overzealous prosecution. It depends on who you ask.
Either way, it shapes the risk calculus for companies and politicians in Chile.
What happens next for the defendants and the case
For Longueira, Enríquez-Ominami, and Contesse, the acquittal clears their names in criminal court. The reputational shadow of a decade-long investigation does not vanish overnight.
Longueira and Enríquez-Ominami have both had national political profiles. Contesse was the public face of SQM during the years in question.
None of them face immediate legal consequences. That holds unless the annulment appeal succeeds.
For observers, the practical takeaway is simple. Wait for the 30-day window to close.
If the Public Ministry stays silent, the case is done. If it files the appeal, expect another round of legal analysis and headlines.
Either way, the SQM case ruling is now public record. All 4,356 pages of it will be cited in Chilean legal circles for years.
