Case Law of the Supreme Court of Justice of the Nation
The right to know one's biological origins helps minors form an identity and promotes the healthy development of their personality.
This is because knowledge of one’s biological origins provides individuals with family, genetic, and historical information that allows them to: a) construct a personal truth based on knowledge and understanding of their own roots; and b) develop and build a social identity based on who they choose to be; therefore, it is essential for the construction of personal identity.

Case Law of Regional Circuit Courts
Civil law provisions regarding the annulment of marriage do not establish discriminatory treatment based on marital status.
The legal distinction does not violate the principle of equality nor is it based on marital status as a factor for exclusion; rather, it is based on the legal priority of the first valid and ongoing marriage over a second marriage entered into with a legal impediment, as this is a rule of validity and legal certainty.

Individual Opinion of the Circuit Courts
The exemption from the requirement to file a notice of the first sale of real property under the legislation on the prevention of transactions involving funds of illicit origin is renewed upon fulfillment of any of the conditions set forth therein.
The reporting exemption for certain vulnerable transactions covers alternative and independent scenarios—not cumulative requirements—since its purpose is to ensure the traceability of funds; requiring simultaneous compliance with all scenarios would impose an unforeseen restriction and would make it mandatory to report transactions that are already fully identifiable. Therefore, it is sufficient to meet any one of the scenarios for the exemption to apply.

Individual Opinion of the Circuit Courts
When filing a claim for inheritance, the exception regarding the statute of limitations does not apply [Legislation applicable in the State of Zacatecas].
This is because the laws of the State of Zacatecas provide that the statute of limitations does not apply, among other cases, to probate proceedings, but it does apply to proceedings conducted independently. Therefore, since the action to claim an inheritance is excluded from this exception, the statute of limitations does apply.

Individual Opinion of the Circuit Courts
Any greenhouse gas emitted from the facilities of the liable parties is subject to the tax, regardless of its origin [Applicable legislation in the State of Zacatecas].
This is because the tax base for the environmental tax in Zacatecas includes any greenhouse gas emitted from the facilities of the entities subject to the tax, regardless of whether it comes from stationary or mobile sources, provided that it impacts the environment, in accordance with the “polluter pays” principle, which aims to protect health and the environment.

Individual Opinion of the Circuit Courts
The refusal of health care institutions to provide medical treatment to children with disabilities violates their right to health and must be evaluated from an intersectional perspective that also protects their caregivers.
In the best interests of the child and in accordance with the right to health, public institutions must guarantee that children with disabilities receive medical treatments that are medically beneficial to their holistic development; therefore, any unjustified refusal to provide such treatments violates their rights. To adequately protect this group in a situation of extreme vulnerability, authorities must adopt an intersectional approach, which allows for an analysis of how factors such as age, disability, and other conditions intersect to compound their disadvantages.

Case Law of Regional Circuit Courts
The applicable regulations governing notifications related to procedures for the collection of claims arising from the nonpayment of fees for the use of radio spectrum frequencies are set forth in the Federal Law on Administrative Procedure.
Although the proceedings initiated by the now-defunct IFT for nonpayment of fees for the use of frequencies are governed by the repealed Federal Telecommunications and Broadcasting Law, that law does not regulate how notifications must be served in such proceedings, since Article 302 refers only to the enforcement of fines. Therefore, pursuant to Article 6, Section IV, in the absence of specific regulations, the Federal Law on Administrative Procedure must be applied by way of analogy to determine the requirements and formalities for notifications, which is consistent with the administrative nature of the proceeding itself.

Individual Opinion of the Circuit Courts
The simultaneous, unedited, and complete rebroadcast of over-the-air television on pay TV does not constitute a violation.
According to Article 231, Section I, of the Federal Copyright Law (LFDA), the retransmission in hotels of audiovisual works from over-the-air television via closed-circuit television systems does not require authorization nor does it generate additional remuneration for the copyright holder, provided that the signal is reproduced in its entirety, simultaneously, and without modifications, as it is subject to the free-to-air regime derived from the “must carry” and “must offer” rules.

Individual Opinion of the Circuit Courts
A provisional injunction with restorative effects is granted against the failure to make reasonable accommodations to the procedure for people with visual impairments.
The foregoing is based on the fact that the requirements of Article 128 of the Amparo Law have been met, given the complainant’s express request, and because granting the preliminary injunction does not violate public policy provisions nor harm the public interest. It is not feasible to deny the suspension on the grounds that it coincides with the effect of a potential judgment granting the relief, because the analysis of the merits cannot be prioritized over the provisional restoration of a right; neither takes precedence over the other, since both the suspension and the main proceedings must be in harmony to achieve the purpose of the amparo proceeding, which is to effectively protect human rights.
