Article 8 of the Mexican Constitution protects the right of petition: “Los funcionarios y empleados públicos respetarán el ejercicio del derecho de petición, siempre que ésta se formule por escrito, de manera pacífica y respetuosa” (Public officials and employees shall respect the exercise of the right of petition, provided that it is made in writing, peacefully and respectfully).
The protection of the petition depends in part on its tone.
