A report into the causes of the Mexico City metro collapse that killed 26 people last year pointed to failures across the administrations of two mayors who are now presidential hopefuls.
Initial results from an audit by Norwegian consultancy DNV said last year that the crash was caused by a series of faults during construction in that section of the metro line, which was built by billionaire Carlos Slim’s Carso Infrastructure and Construction while Marcelo Ebrard, currently Mexico’s foreign minister, was mayor.
In a final report published on Wednesday by the city government, DNV also said there was no evidence that routine line maintenance meant to find potential problems had been performed after its completion, implicating subsequent administrations including that of current mayor Claudia Sheinbaum.
Last week Sheinbaum, who commissioned DNV to run the audit, accused the company of conflicts of interest and said there were inconsistencies between their initial and most recent work. She said she would rescind the company’s contract and has threatened to file a criminal complaint against its representatives.
“We think there is political bias in the last report,” Sheinbaum said this week.
President Andrés Manuel López Obrador on Wednesday backed Sheinbaum, saying she was an honest woman who was being put under enormous pressures.
Ebrard last year defended the design and building of the line and said all decisions were “based on efficiency and technical aptitude” by experts and officials.
DNV did not immediately respond to a request for comment. In a statement last week it said that it stood by its methodology and that no experts involved in the report had conflicts of interest.
Ebrard and Sheinbaum are tied in voter preferences among presidential candidates to succeed López Obrador, according to a poll from Reforma newspaper published on Monday.
The rejection of the report and threats of criminal action against the consultants caused alarm in the country’s private sector. They also fuelled fears that the technical and criminal investigations will not hold those responsible accountable.
“The Mexico City authorities look more interested in stopping justice being done,” said Marco Fernández, a researcher at think-tank México Evalúa and professor at the Tec de Monterrey’s School of Governance.
“Everything points to serious problems of negligence in the construction and the supervision . . . and obviously the negligence that’s very uncomfortable for the current government on the lack of inspections.”
No one has been charged in connection with the collapse, more than a year since it happened. Prosecutors have said they may soon bring charges.
Slim’s company Grupo Carso last year reached a deal with the city government to pay to repair the line and fund compensation for victims, although it said at the time that it did not cause and does not accept responsibility for the crash. A spokesman did not immediately respond to a request for comment.
