On August 9, while protests continued to expand, a partial recount was undertaken by election officials after being ordered to do so by the country's Federal Electoral Tribunal (TEPJF, sometimes referred to by the acronym of its predecessor, the TRIFE).

  Passage: The "Desafuero" of Andrés Manuel López Obrador was the removal of López Obrador's state immunity from prosecution.  It took place during 2004 and 2005.  This process was originated by a land owner who sued the Federal District's government on the grounds of improper expropriation of a patch of land called "El Encino".  This case detonated in López Obrador's (AMLO) hands in 2005, when a vote by the Chamber of Deputies lifted his constitutional immunity against criminal charges.
