The Supreme Court of Justice of the Nation (SCJN) declared several provisions of the Nayarit Livestock Law invalid. It required state authorizations to transport and export cattle and other agricultural products.
The ruling came amid Constitutional Controversy 216/2025 and marks a before and after. Now states may require documents proving who owns the cattle, but they may not create their own permits to authorize its transport when that regulation falls under federal authorities.
Mexico Supreme Court: What permits to transport cattle were invalidated?
The ruling affects provisions of the Nayarit Livestock Law that established state requirements for moving cattle and other products of animal origin.
Among the package of affected measures are the authorizations and documents that functioned as a prior permit to allow the transport, that is, the Supreme Court considered that the state could not condition the movement of cattle when it involved controls that fall under the federal government.
Producers may still be required to prove ownership or origin of the cattle.

Are all documents needed to transport cattle in Mexico eliminated?
The Supreme Court distinguishes between the documents used to identify the owner and prove the origin or transfer of the animals, and the permits that authorize or prevent their transport.
Nayarit may establish requirements related to cattle ownership because it is a matter that the state may regulate. What it cannot do is use those documents to create an authorization system over matters that correspond to the federal government.
Cattle export: What changes with the Supreme Court ruling?
The ruling covers provisions related to the departure and export of cattle, livestock products, and byproducts.
The Supreme Court determined that Nayarit may not require an additional state authorization when it comes to matters whose regulation corresponds to federal authorities. This does not mean that the requirements for exporting cattle from Mexico disappear either. Producers will still have to comply with the applicable federal, sanitary, and commercial rules.
The change lies in who may impose each requirement. Nayarit retains its powers over local matters, such as certain ownership documents, while it may not establish permits that encroach on powers reserved to the federal government.
