Our professional range is extensive, covering amparo lawsuits, motions of unconstitutionality (acción de inconstitucionalidad), constitutional controversies (controversia constitucional), constitutional advice and economic regulation, as well as the design and execution of strategic litigation.
CyMA has ample experience appearing before Mexico’s Supreme Court and other federal courts, successfully arguing high profile cases that involve aspects of constitutionality or pertain to human rights.
We have focused this brand of complex constitutional litigation on highly regulated sectors such as telecommunications, broadcasting, mobility, energy, finance, data and privacy, responsibilities of public servants, to name a few.
Our firm has positioned itself as one of the most prestigious tax litigation firms in Mexico. We assist our clients in their interaction with the different tax authorities and in structuring and implementing their legal defense against acts of authority that violate their constitutional and legal rights.
Likewise, we provide advice to our clients on compliance and interpretation of the various Mexican and international tax provisions, always seeking to optimize the tax burden of their business and estate-related activities.
We have a solid administrative litigation and regulatory law department, specializing in public procurement, telecommunications, broadcasting, expropriations, administrative and compensation liability of public servants, energy law, urban development, among others.
Our lawyers regularly -and oftentimes successfully- file appeals and administrative lawsuits to adequately defend the rights of our clients.
Our antitrust and regulated sectors’ practice offers integral advice with respect to the various procedures substantiated before the Mexican antitrust authorities, Federal Antitrust Commission (Cofece) and Federal Telecommunications Institute (IFT), energy sector and other regulators.
The CYMA team also provides regulatory consulting services, such as compliance with applicable legislation in connection to all competition and antitrust matters, the telecommunications and energy sectors as well as other highly regulated markets, also advising our clients in all interactions with regulators.
Being that administrative and constitutional litigation is CYMA’s core practice, the firm has a unique advantage in challenging the regulators’ rulings before the federal courts. The antitrust and regulated sector’s practice works closely with our trial lawyers in connection with all matters subject to judicial review, which allows us to offer our clients “end-to-end” advice, including all phases of a procedure.
A central component of our firm is the handling of strategic pro-bono litigation that has a significant impact on the Mexican legal system. Some of the fields we cover are equality and non-discrimination, anti-corruption, adequate use of public funds and accountability of public officials, militarization, gender, health, freedom of expression, among others.
