Article 165. Laws shall be proposed:
1. If they are organic laws:
a. by permanent committees of the National Assembly;
b. by the Ministers of State, as authorized by the Cabinet Council;
c. by the Supreme Court, Attorney General of the Republic, and Solicitor General of the Administration, as long as they refer to the enactment or amendment of the National Codes;
d. by the Electoral Tribunal on matters within its jurisdiction;
2. If they are ordinary laws:
a. by any member of the National Assembly;

Article 203. Organic Laws are those designated as such by this Constitution, those enacted to organize public powers or to develop constitutional rights, and those which serve as a regulatory framework for other laws.
Any bill for the enactment of an organic law, except in the case of those defined as such in the Constitution itself, must first be accepted by the National Assembly, by a two-thirds vote of the members present before the beginning of debate on the bill. This qualifying vote shall also apply to the process of amending organic acts.
Laws defined by the National Assembly as organic acts shall be sent, prior to promulgation, to the Constitutional Division of the Supreme Court of Justice for a ruling on the constitutionality of their organic status. The Constitutional Division shall reach a decision within 10 days of receipt of the communication. If the Constitutional Division rules that the law is not organic, the law shall lose that status.
Enabling laws are those enacted by a three-fifths vote of the members of the National Assembly to establish the guidelines, purposes and framework for matters that are delegated to the President of the Republic, which have the rank and force of law. Enabling laws should set the period during which they are in force.

The topic of intermediate laws has been debated in Mexico by the respected jurist Héctor Fix-Zamudio. Fix-Zamudio argues that one way of mitigating the regulatory trend that is reflected in the constitutional reforms is by adopting a form of laws midway between the fundamental law and ordinary laws. He prefers to call them organic laws, as he rightly observes that constitutional laws are all those that have been declared in accordance with the Constitution. Agreeing fully with the view supported by the distinguishing jurist, there is the practical problem that there are already 26 laws that include in their name that of organic law.

On the other hand, one might argue that if today the term constitutional as applied to the laws, plays an adjectival function, the use of that same word could well be distinguished in its function as a noun. But the semantic differentiation based on the fact that the word constitutional in some cases would have an adjectival function and in others a noun function could cause confusion, which is contrary to the intention that this modality offer solutions rather than create new problems. Therefore, a less confusing term is preferred: constitutional development laws. Thus is the obstacle of the laws already known as organic and those classified as constitutional overcome, and, at the same time, the historical proposal of 1847 is utilized with a reasonable change.

The advantages of the introduction of constitutional development laws to the system of sources of Mexican law can be summarized as follows:

  1. These laws would keep the Constitution from having rules that incur excessive detail. It would allow Congress to adopt rules through an aggravated procedure that, while alleviating the excessive growth of the Constitution, would provide a new way to reach agreements between the representative forces, at the same time protecting political minorities in Congress.
  2. The duration of a consensus would be assured because the required majority is even greater than that required for constitutional reforms in Congress.
  3. It would expand the powers of the Supreme Court of Justice, introducing the prior control of constitutionality of laws.
  4. It would reduce the need for amendments and additions to the Constitution, thus bringing greater stability to the constitutional text and its jurisprudence and thereby contributing to legal certainty for citizens and the enhancement of legal culture.
  5. It would provide that amendments to the Constitution be drafted according to enhanced technical critera, at the same time encouraging the adoption of laws that are briefer and of more general content.

As is well known, the text of the Constitution has undergone numerous reforms. Although in the majority of cases it is possible to demonstrate their necessity and usefulness, their adoption has tended to become increasingly regulatory in character. At present, our supreme law is already among the most extensive in the world, and it is likely to continue to be the object of additions and reforms in the coming years. If we continue the pace of recent years, we will have a Constitution that is inaccessible to those who are not lawyers, and even to them.

The Constitution is the supreme law of the State, but this does not mean that it must contain all its legislation. On the contrary, as the heart of the national legal system, the Constitution can and should be brief – for several reasons. On the one hand, given its rank and importance, it is desirable that the citizenry in general be familiar with it. This becomes increasingly difficult due to its growing length and frequent changes. Secondly, it is important that the ordinary legislator can make the institutional adjustments that the times require, but always within what the Constitution provides and without having to submit it to endless adjustments that have made it become the most flexible of the legal codes in force in the country. Third, there is a constitutional court that controls the strict compliance with the fundamental law, so there is a full guarantee that Congress will never exceed the exercise of its powers.

In light of the arguments and the experiences already mentioned above, it is desirable to adopt the concept of “constitutional development laws”. These laws present two important differences compared to the others that Congress passes. On the one hand, a qualified majority, or two-thirds of the members present in each Chamber, is needed for their approval. This incorporates a principle of rigidity that gives stability to these laws. Thus, the consensus reached to formulate them will be maintained over time, although this will not prevent subsequent agreements from being translated into the reform or repeal of these constitutional development laws, but always by the same majority required for their approval.

A second element of the type of laws proposed is that they are made subject to an assessment of their constitutionality by the Supreme Court of Justice. The presidential veto is not applicable in this case, because in order to override it, the Constitution requires a majority in both chambers, which is equivalent to that which is proposed for its approval.

In sum: the Constitutional Development Law is distinguished from ordinary laws because (1) its approval requires a qualified majority in each chamber of the Congress of the Union, and (2) because of the way of addressing said observations through a prior opinion of constitutionality by the Supreme Court of Justice of the Nation. Finally, the proposed law would reflect and develop in greater detail the general laws contained in the Constitution.
