Form of government


What is the basic source of law? Describe the scope of, and limitations on, government power relevant to the regulation of lobbying and government relations.

The basic source of law in the United Mexican States (Mexico) is a written federal constitution dating from 1917 (the Constitution), which consists of 136 articles, many of which have been somehow amended throughout all these years.

Also, as a federal republic, Mexico’s 32 federative states enjoy sovereignty and are free to issue their own laws. In this regard, all federative states have their own constitution and their own local laws and regulations (only certain specific matters are reserved to be legislated by the federation). Additionally, each federative state is divided into several municipalities. Each municipality is empowered to issue local rules, regulations, communications and administrative provisions of general observance.

The only limitation to the legislative freedom of the federative states is that no laws or regulations can be approved or passed if they oppose the federal Constitution and its principles.

Fundamental human rights, such as freedom of speech (as long as it does not attack the moral, private life or any third parties’ rights, constitutes a crime or disturbs public order), freedom of assembly (as long as it is for legal purposes and unarmed) and the right to petition the government (as long as it is exercised in writing, in a respectful and peaceful manner), are contemplated in the Constitution. However there are no articles regarding any strict lobbying regulation.

Legislative system

Describe the legislative system as it relates to lobbying.

At federal level, the Mexican Congress of the Union is bicameral, dividing legislators into two separate assemblies: the House of Representatives and the Senate. The House of Representatives is composed of 500 congressmen, of whom 300 are elected by direct popular vote. The remaining 200 are elected by indirect vote, in connection to the voting percentage each political party gets. The Senate is composed of 128 senators, of whom 96 are elected by direct popular vote, and the remaining 32 are elected by an indirect vote.

At a local level, each federative state has its own House of Representatives, in accordance to its respective local constitution.

The President, the members of the Congress of the Union and the members of the House of Representatives of each federal state (only at local level) are entitled to issue laws or decrees. However, the President, as head of the executive branch, is entitled to issue secondary legislation in order to provide the specific rules and guidelines for the application of general and federal laws.

National subdivisions

Describe the extent to which legislative or rule-making authority relevant to lobbying practice also exists at regional, provincial or municipal level.

Mexico is a republic, and a democratic federation, and thus is divided into several states, which in turn are divided into many municipalities. The Constitution grants both the states and the municipalities the faculty to create and issue their own laws and regulations (including secondary regulation), but only for specific matters that are not expressively reserved to the federal authorities, such as federal taxation.

Since lobbying is not a topic expressively reserved to the federation, state and municipality governments are completely entitled to create their own laws and regulations regarding lobbying throughout the legislative process established in the Constitution. Nonetheless, lobbying is commonly regulated in the internal regulations of each local congress.

Consultation process

Does the legislative process at national or subnational level include a formal consultation process? What opportunities or access points are typically available to influence legislation?

Mexican citizens are entitled to vote in legal and binding referendums in terms of article 35 of the Constitution.

According to the above-mentioned article, referendums shall be summoned by: (i) the President; (ii) 33 per cent of the members of the House of Representatives or the Senate and; (iii) 2 per cent of the citizens registered in the Nominal List of Electors. The outcome of this voting shall be binding only in the event that 40 per cent or more of the citizens registered in the Nominal List of Electors participate in the corresponding referendum.

Likewise, human rights, form of government, electoral principles, state budget, national security and the organisation of the armed forces are matters that cannot be subject to referendum. The Mexican Supreme Court (the highest judicial authority in Mexico) shall consider the legitimacy of the referendum before it may be held.

Any referendum shall be organised by the National Electoral Institute (known as INE from its its acronym in Spanish).


Is the judiciary deemed independent and coequal? Are judges elected or appointed? If judges are elected, are campaigns financed through public appropriation or candidate fundraising?

As previously stated, at federal level, the Mexican government is divided into three different, independent and coequal powers: the executive branch (headed by the President); the legislative branch (made up of the House of Representatives and the Senate); and the judiciary branch (headed by the Supreme Court, and composed of different tribunals).

According to article 94 of the Constitution, all judges in the Judiciary branch are appointed, as follows.

  • Judges from the Supreme Court are elected by the Senate (two-thirds of the Senators vote), from a three-person list proposed by the President.
  • Circuit magistrates and judges are elected by the Federal Judicial Council, a government body in charge of supervising the judiciary branch.

At local level, each federative state has its own judiciary branch for matters reserved not to the federation but to local state government. Each local judiciary branch shall be integrated in accordance with local laws and provisions.

Regulation of lobbying


Is lobbying self-regulated by the industry, or is it regulated by the government, legislature or an independent regulator? What are the regulator’s powers?

Lobbying activities are regulated in the rulings of the House of Representatives and of the Senate. The nature of these regulations result from an administrative procedure; in this specific case every state has its own House of Representatives, consequently every state has it own lobbying regulation.

All individuals interested in conducting lobbying activities must register in a lobbying registry valid for each legislature. The acceptance of any gift by lawmakers from lobbyists is strictly forbidden and shall be punished in accordance with the General Law of Administrative Responsibilities, and with the criminal code.

In order to procure transparency, all lobbying documents shall be published in the corresponding Congress’ chamber web page. Also a non-profit association named PROCAB is deeply involved in lobbying activities. PROCAB is in charge of registering all working lobbyists in Mexico (lobbyists may affiliate or may not, it is not mandatory) in order for them to procure events, courses or any other activities that may contribute to their effort of lobbying on behalf the interests of their clients.


Is there a definition or other guidance as to what constitutes lobbying?

Article 263 of the House of Representative’s Ruling provides a similar definition to the aforementioned one.

It is mandatory to anyone who wishes to carry out lobbying activities to register in a specific lobbying registry (at the beginning of every legislative term).

This registration shall be published every six months in the Parliamentary Gazette and throughout the website of the House of Representatives. The registration will only be valid throughout the correspondent legislative term.
