Article 93 Political Constitution of the United Mexican States

The Secretaries of the Office, once the period of ordinary sessions is open, shall report to the Congress on the state of their respective branches.

Either of the Chambers may summon the Secretaries of State, the directors and administrators of the parastatal entities, as well as the heads of the autonomous organs, so that they report under oath to tell the truth, when a law is discussed or a matter concerning their respective branches or activities is studied, or so that they answer interpellations or questions.

The Chambers, at the request of one fourth of their members, in the case of the deputies, and of one half, in the case of the Senators, have the power to form commissions to investigate the operation of said decentralized agencies and majority state-participation companies. The results of the investigations shall be made known to the Federal Executive.

The Chambers may require information or documentation from the heads of the agencies and entities of the federal government, by means of a written question, which must be answered within a term no greater than 15 calendar days from its receipt.

The exercise of these powers shall be carried out in accordance with the Congress Law and its regulations.
