José López, a former Secretary of Public Works, has lost his appeal to reduce his 13-year prison sentence. López was convicted on charges including corruption related to public works projects, illicit enrichment, and illegal possession of firearms. His legal team argued for a four-month reduction based on his completion of two marketing courses. However, the Federal Court of Cassation upheld previous rulings denying the reduction. The court aligned with lower instances in rejecting the claim that the courses warranted a lighter sentence. López remains incarcerated, with his original sentence intact. This decision closes a recent attempt to appeal his conviction and penalty.
