After gaining fast-track approval, President López Obrador issued the Law for Transparency, Prevention and Combating Improper Practices in Advertising Contracting (the Advertising Contracting Law) in the Official Gazette on 3 June 2021. This will become effective on 2 September 2021 and will grant new powers to the Federal Economic Competition Commission (COFECE) but may fall outside the constitutional objectives of the competition authority. Application of the new law may be problematic and may disregard the competence of the Federal Telecommunications Institute (IFT).
