OHL announced that it won the court battle to defend its subsidiary Autovías Concesionadas OHL, S.A. in September 2012.

The company went to court after the Puebla government's May 9 decision to cancel the deal with OHL for the $226 million Libramiento Norte De Puebla highway.

The decision of the court states that the company should have been given a guarantee of a hearing in the case involving the revocation of the firm's concession to build and operate a highway

The ruling in favor of OHL was based on the fact that there was no guarantee of a hearing provided before the decree whereby the state government withdrew the firm's concession to build and operate a stretch of highway 35 kilometers (22 miles) long.The government had argued that "there were a dozen serious irregularities" in the awarding of the contract. The previous state administration, which signed the concession with OHL, was headed by the Institutional Revolutionary Party, or PRI.The company argued that it obtained the concession in 2008 in accordance with "the strictest legality."
