Legal proceedings regarding the 2021 Mexico City Metro Line 12 collapse have faced delays. A judicial hearing involving eight defendants, including former Metro Project Director Enrique Horcasitas, was postponed for a second time to November 26. Defense attorneys requested the delay, claiming they had not been provided with the full investigation file.

The original May 3, 2021, collapse between the Olivos and Tezonco stations resulted in 26 deaths and over 100 injuries. Investigations into the incident have identified structural failures and deficiencies in construction and maintenance.
