The 111th article of the Mexican Constitution states that most high-level elected officials cannot be prosecuted for criminal offenses while in office without a simple majority vote of the Chamber of Deputies stating there are grounds for prosecution. This privilege is usually confused with the freedom of speech protection granted to members of congress by the 61st article, known as "fuero" (from Latin "forum"), the process to strip it is known as "desafuero". Since immunity from criminal prosecution is almost universally confused with the "fuero", both terms will be used interchangeably.
