Mexico Court Confirms UIF Authority to Freeze Accounts Without Judicial Orders

The Supreme Court of Mexico has confirmed the Financial Intelligence Unit’s (UIF) authority to freeze bank accounts without requiring prior judicial orders in cases of suspected money laundering or terrorism financing, according to Expansion MX and Aristegui Noticias. This ruling reverses previous legal constraints limiting account blockages to requests from foreign authorities, marking a significant expansion of the UIF’s enforcement powers.

Between 2018 and 2025, Mexican federal judges ordered the unblocking of 2,836 bank accounts totaling 32 billion pesos, El Financiero reports. These actions followed judicial reviews questioning the legality of account freezes, reflecting tensions between financial regulation efforts and judicial oversight under the new Supreme Court precedent.

The decision has drawn criticism from lawmakers in the PAN and PRI parties, who warn that the UIF’s discretionary freezing powers risk undermining legal certainty and constitutional protections for property rights. According to El Financiero, these legislators have called for reforms to impose limits on the length of freezes and incorporate stronger judicial review mechanisms to prevent potential abuse.

The ruling impacts high-profile investigations, including the UIF’s case against Fresh Packing Corp, a company linked to Ismael El Mayo Zambada's nephew, whose bank accounts were frozen amid suspicious transactions totaling approximately $21 million, El Financiero details. This enforcement demonstrates the practical application of UIF’s expanded powers in targeting suspected illicit financial activities.

Looking ahead, the ruling’s implications for judicial oversight and the balance between anti-money laundering efforts and legal safeguards remain closely watched. Pending legislative responses and how courts may further interpret UIF’s authority will shape Mexico’s approach to financial crime enforcement and property rights protections in the coming years.
