Dutch Marengo Trial Leaves Convicted Drug Lord Without Counsel

The Marengo Verdict and Its Aftermath

Ridouan Taghi received a life sentence in February 2024 for five murders and leading a criminal organization that moved multi-ton cocaine shipments from South America through Rotterdam's port into European markets. The verdict concluded a trial that began in 2019 under the code name "Marengo," named after a battle Napoleon won against overwhelming odds. Dutch prosecutors characterized Taghi's network as the most violent drug trafficking organization in modern European history.

Taghi's conviction rested on decrypted EncroChat messages and testimony from crown witness Nabil B., whose brother and lawyer were both murdered during the trial. The court found Taghi personally ordered executions to silence informants and rivals. He was arrested in Dubai in December 2019 after two years as Europe's most-wanted fugitive.

No Attorney Will Take the Case

As of May 2026, Taghi's appeal remains unscheduled because no licensed Dutch criminal defense attorney has agreed to represent him. The Dutch Bar Association confirmed that at least 12 senior advocates declined the case between March and May. Two cited explicit death threats received after preliminary inquiries. Others referenced "irreconcilable professional risk."

Dutch law guarantees the right to counsel. But it doesn't compel any individual lawyer to accept a client. The impasse has no clear procedural resolution. The Amsterdam Court of Appeal can't proceed without defense representation, yet can't force the bar to provide it.

A Decade of Intimidation

The Marengo trial saw violence that reshaped Dutch legal practice. In September 2019, attorney Derk Wiersum, who represented crown witness Nabil B., was shot dead outside his Amsterdam home. In July 2021, crime journalist Peter R. de Vries—who advised Nabil B.—was gunned down in central Amsterdam and died nine days later. Prosecutors linked both murders to Taghi's network.

Two of Taghi's own defense attorneys were arrested in 2021 on charges of smuggling messages between Taghi and his organization from inside the high-security prison in Vught. One attorney, Inez Weski, was convicted in 2023 and disbarred. The arrests sent a signal across the Dutch legal community: representing Taghi carried risks from both the state and the underworld.

Rotterdam Port and the Cocaine Pipeline

Taghi's organization exploited corrupt port workers and container logistics at the Port of Rotterdam, Europe's largest seaport, to move an estimated 20 tons of cocaine annually between 2015 and 2019. Prosecutors documented a system in which dock workers received encrypted coordinates to retrieve specific containers before customs inspection. The cocaine, shipped from Ecuador and Colombia in fruit and flower shipments, was offloaded into warehouses controlled by Taghi's lieutenants.

Dutch authorities estimate the network generated €200 million per year in wholesale revenue. The operation's sophistication—and its willingness to use lethal violence—marked a turning point in European drug enforcement.

European Precedent and Legal Stalemate

No EU member state has faced a comparable situation in which a convicted organized crime leader can't secure appellate counsel due to intimidation. Legal scholars at Leiden University have called the impasse a "stress test" for rule-of-law guarantees. If Taghi's appeal can't proceed, his life sentence becomes functionally unreviewable—a due-process failure that could trigger European Court of Human Rights scrutiny.

Germany's Federal Criminal Court and Italy's anti-mafia courts have handled similarly violent defendants, but both systems allow court-appointed public defenders with state protection. The Netherlands has no equivalent mechanism for appellate cases. The Dutch Ministry of Justice hasn't commented on whether it will seek emergency legislation.

What Happens Next

The Amsterdam Court of Appeal has set a June 30, 2026 deadline for Taghi to secure representation or for the Ministry of Justice to propose a procedural solution. If neither occurs, the court has three options: delay the appeal indefinitely, appoint a lawyer over their objection (legally untested), or declare the appeal abandoned (likely unconstitutional).

Taghi remains in the EBI prison in Vught under the most restrictive detention regime in Dutch corrections. His co-defendants in Marengo—16 were convicted alongside him—have all filed appeals with representation. None of their lawyers will cross-represent Taghi.

We'll be watching whether the Dutch Bar Association convenes an emergency session before month-end, and whether any European human rights body intervenes before the June 30 deadline.
