Background on the Amparo Law and its Relevance

The Ley de Amparo is a crucial piece of Mexican legislation that protects citizens’ constitutional rights. It allows individuals to file lawsuits, known as amparos, to challenge government actions that may infringe upon their rights. The law has been instrumental in safeguarding citizens’ freedoms and ensuring accountability from public authorities.

Senado de la República Proposes Reforms

On October 2, the Mexican Senate approved a reform to the Amparo Law, initiated by Claudia Sheinbaum, the Chief Executive of Mexico City. The reform aimed to modify various aspects of the law, but it sparked controversy due to an added transitional article that implied retroactive application.

The Controversial Transitional Article

The disputed transitional article stated that any pending amparo cases at the time of the reform’s enactment would continue to be resolved under the new regulations. Critics argued that this provision would unjustly affect thousands of ongoing amparo cases, potentially violating citizens’ rights.

House of Representatives Deliberates on the Reform

Ricardo Monreal, president of the Junta de Coordinación Política (JCP) in the Chamber of Deputies, praised the Senate for refraining from making changes to the transitional article outside the legislative process. This decision aimed to prevent any potential violation of the legislative procedure.

Opposition Parties Voice Concerns

Leaders from opposition parties, including Elías Lixa (PAN) and Rubén Moreira (PRI), expressed their opposition to the proposed Amparo Law reforms. They argued that the changes would be detrimental and arbitrary, affecting the rights of approximately 200,000 Mexican citizens, including small business owners and entrepreneurs with ongoing disputes with the Secretaría de Hacienda y Crédito Público (SHCP).
