Malpica, Iturbe, Buj & Paredes (MIB&P) is known for offering some of the most specialised litigators in Mexico. The antitrust practice is led by a team of four partners and ten associates who combine deep knowledge of economic competition with extensive litigation experience. This blend of technical and procedural strength enables MIB&P to not only rep - resent clients before the antitrust authorities but to effectively challenge resolutions before specialised federal courts and the Supreme Court of Justice. This strategy gives clients a decisive advantage at

every stage – investigations, trial-like proceedings, or appeals. By shaping defences in the earliest phases before the competition authority, MIB&P ensures that arguments are both technically sound and proce - durally positioned for judicial review. This integrated approach heightens the chances of favourable out - comes and strengthens the firm’s reputation as a leader in antitrust advocacy and litigation. The team has also successfully advanced innovative consti - tutional arguments, strengthening MIB&P’s rapidly growing reputation in antitrust litigation.
