“Seen but Not Proven: Legal Limits and the Cartel Conundrum”

Sometimes in law, what is unseen matters as much as what is visible — like the roots of an oak tree burrowing deep beneath the soil, unseen but essential to the tree’s strength. So too with cartels and secret agreements among powerful businesses: their effects ripple through markets, consumers, and economies, yet the very evidence that reveals them often lies hidden in private conversation and covert recordings. When a high court, tasked with balancing justice and legality, determines that such evidence cannot be admitted, the result can feel like watching those roots recede from sight — still there, still shaping the ground beneath us, yet no longer traceable with the tools we once used.

On January 17, 2026, Latvia’s Supreme Court issued a ruling that has sent ripples through established practices in competition enforcement. At issue was the inadmissibility of covertly recorded conversations as evidence in cartel cases — communications that had previously served as central proof of collusion among competing companies. The decision has unsettled antitrust authorities and sparked public debate about the future of cartel detection and prosecution in the country.

The case under discussion involved what had been regarded as a high‑profile construction cartel, where rival firms were captured on tape discussing illicit coordination of markets. These recordings, obtained via authorized operational activity and corroborated by expert analysis, appeared to clearly show the illegal agreements. Yet the Supreme Court concluded that such operationally obtained evidence cannot be used in administrative proceedings for competition violations — a category that includes many cartel enforcement actions.

For the Chairwoman of Latvia’s Competition Council, Ieva Šmite, this outcome feels like a legal paradox: “The cartel was visible to everyone,” she noted, “and the evidence was authentic — yet it has been rendered unusable.” Šmite emphasized that without these recorded conversations, there may be no practical way to document certain violations, since cartel participants typically avoid written or digital trails and instead rely on discreet, verbal arrangements.

In contrast, Supreme Court Judge Anita Kovaļevska defended the decision on procedural and constitutional grounds. She stressed that courts must adhere strictly to the letter of the law and international human rights standards, particularly regarding covert operational activities that significantly intrude on individual rights. From this perspective, even strong evidence must bow to the limits legally imposed on how it was acquired.

The ruling exposes a fault line between legal formality and substantive justice — a tension familiar in many judicial systems. Critics argue that safeguarding civil liberties is essential, but they also warn that without effective tools to prove cartels, anticompetitive behavior could go unchecked, harming consumers and the broader economy. Lawmakers and legal scholars are already weighing whether legislative changes might be needed to clarify the rules of engagement in such cases.

By refusing to admit certain covertly obtained evidence, the Supreme Court has reshaped the practical landscape of cartel enforcement in Latvia. What was once common practice may now be impermissible, prompting renewed reflection on how legal systems can fairly balance individual rights with the public interest in competitive markets. As this debate unfolds, courts and legislators alike will be tasked with finding a path that protects both the rule of law and the substantive tools needed to uncover hidden collusion.
