Faced with rampant drug violence and homicides at record highs, President Andres Manuel Lopez Obrador‘s government is preparing far-reaching reforms of Mexico’s justice system to combat insecurity and a culture of impunity, officials said on Monday. The reforms, crafted by the attorney general’s office and presidential aides, are expected to be presented in the Senate on Wednesday and potentially passed during a new legislative session that begins in February. Mexican law enforcement agencies have suffered several spectacular security setbacks since Lopez Obrador came to power a year ago, and his government, which controls both chambers of Congress, is scrambling to address growing insecurity nationwide. The reform would amend several articles of the constitution, create a new criminal code, set out new procedures, modify an existing law that details legal challenges, and change the legal framework of the attorney general’s office and its regulations. “It’s a very ambitious, broad reform,” Sen. Ricardo Monreal, a key legislative leader in Lopez Obrador’s leftist Morena party, told Reuters. Interior Minister Olga Sanchez, Security Minister Alfonso Durazo, Lopez Obrador’s judicial advisor Julio Scherer, and Attorney General Alejandro Gertz would attend a meeting on Wednesday to discuss the reform, Monreal said.
