The request to hear António Mendonça Mendes was presented by the Left Bloc after ‘Negócios’ newspaper wrote at the beginning of the month that the tax office had given up trying to collect €125 million from the company.

Negócios wrote that "the tax office gave up trying to collect €125 million of company income tax from Brisa following the sale of Brazilian company CCR and cancelled the underlying inspection. The decision was taken in 2016 and accounts for more than half the amount cancelled that year, raising criticisms from the Audit Court about the effectiveness of the Large Taxpayer Unit ".
