One ordinary day, you open your email and find a message from the SAT letting you know that you have a notification in your Tax Mailbox. It’s not spam. It’s not a mistake. It’s the beginning of an electronic audit, and if you don’t know how to act, the clock has already started ticking against you.

En México, el silencio de la autoridad ante una petición no es un vacío jurídico. Es una situación que la ley prevé expresamente, y que activa un mecanismo con consecuencias concretas: la negativa ficta, que se presume una resolución desfavorable, o en casos específicos la afirmativa ficta, que equivale a una resolución positiva. Ambas figuras nacen del silencio administrativo y ambas abren puertas legales que el particular puede —y en muchos casos debe— aprovechar.
