The Chamber of Deputies approved and returned to the Senate the reform of the Amparo Law, with a modified third transitory article, which divides the effect of the changes into two moments: the procedural stages already concluded will be governed under the previous provisions, but the subsequent ones, with the new rules.
The wording, which caused a verbal dispute between the parties since it became known hours before their debate, was presented at 1:45 a.m. on Wednesday and led to a two-hour exchange of positions from the rostrum.
Morena explained that, with the changes to the Amparo Law, the offices “that defend businessmen or powerful people” will be stopped from paying taxes and the coordinator of the bench, Ricardo Monreal Ávila, added that this year alone, the amparos have prevented the payment of 100 billion pesos.
As anticipated, the majority bench presented a reservation to define that since it is a procedural law, “the concluded procedural stages that generate acquired rights for the parties will be governed by the legal provisions in force at the beginning of the respective procedures” and that “the actions after the entry into force of the decree… will be governed by the provisions of this new legislation, without implying retroactive application or affecting acquired rights. “Well, these are future actions.”
In the mess over the interpretation of the merits, the president of the Jurisdictional Commission, Hugo Eric Flores (Morena), summarized: “it implies a temporal distinction. What was done remains under the old law; what is done later, under the new one.”
PRI deputy Emilio Suárez Licona pointed out that, under the argument that the Amparo Law is procedural in nature, “the new provisions of the decree are sought to be applied to future actions within processes already initiated, and it is alleged that this does not imply retroactivity. This interpretation is, at the very least, forced and risky.”
Monreal explained that one of the axes of the reform is to prevent protection trials from being prolonged so as not to pay taxes. There are, he explained, thousands of accumulated files, with an average of 16 years old and the most remote dating back 22.
