Legal 500 Editorial commentary
Testimonials
Collated independently by Legal 500 research team.
- It's a practice with a very high technical level, very focused on solving concrete problems. In Public Law, this is especially valuable because it's not enough to simply know the regulations: you also have to understand how the Administration works, the regulatory context, and the impact a decision can have on the business. My experience has been primarily with Oscar Aguilar Valdez, and I believe his knowledge and experience are one of the practice's main differentiators. Compared to other firms, I would highlight the technical quality, the availability, and the ability to provide clear and useful answers for decision-making. I would also emphasize, above all, his great empathy.
- I would especially highlight Oscar Aguilar Valdez. He has exceptional technical knowledge of Public Law, extensive experience, and, above all, excellent judgment. His main strength is his ability to quickly grasp the problem, identify what is truly relevant, and translate complex legal issues into clear and applicable recommendations. I also greatly value his availability and personal involvement in matters. On complex or sensitive issues, his opinion provides considerable reassurance due to the depth of his analysis and his practical understanding of the workings of the public and regulatory sectors.
