(First paragraph was reformed by the decree published on June 6, 2011)
Article 107
All controversies mentioned in the article 103 of this Constitution, except for electoral controversies,
shall follow the legal procedures and formalities established by the statutory law, according to the
following principles:

(Reformed by the decree published on June 6, 2011)
I. The constitutional adjudication (appeal on the grounds of unconstitutionality) shall be carried out at
the request of the offended party. The offended party is the holder of an individual or collective right,
which has been violated by the challenged act, affecting his/her legal framework, either directly or by
the means of his/her special situation before the legal system.

Regarding acts or rulings pronounced by administrative or labor courts, the plaintiff must argue that
he/she holds a subjective right that has been directly and personally affected.

(Reformed by the decree published on June 6, 2011)
II. The sentence pronounced in a constitutional adjudication shall cover only to the plaintiffs, protecting
them only in the specific case concerned in the complaint.

If a court rules unconstitutionality of a general provision for a second consecutive time in constitutional
adjudications, the Supreme Court of Justice of the Nation must notify the authority which enacted such
provision.

When the bodies belonging to the Federal Judicial Branch establish legal precedents by repetition,
ordering unconstitutionality of a general provision, the Supreme Court of Justice of the Nation shall
notify the authority which enacted such provision. If after 90 days the unconstitutionality is not
overcome, the Supreme Court of Justice of the Nation shall issue a declaration of unconstitutionality,
indicating its scope and conditions, according to the statutory law. Such declaration must be approved
by a majority of 8 votes.

The previous two paragraphs do not apply to general provisions which regulate taxes.

In a constitutional adjudication, any deficiency regarding the terms “violation” and “grievances” should
be corrected by the court, according to that established in the statutory law.

Whenever the acts claimed in the constitutional adjudication deprive or may deprive the farming
cooperatives or communities or their members of their lands, waters, pasture and mountains, all
evidence that could benefit any of the aforesaid entities or individuals must be obtained at the court’s
own motion, and any proceedings that could be necessary to prove their rights must be ordered. Also,
the nature and consequences of the claimed acts shall be defined.

In the constitutional adjudication mentioned in the preceding paragraph, dismissal of the suit because
of procedural inactivity or by discontinuance shall not be admissible to the detriment of farming
cooperatives or indigenous communities, or to the detriment of a native or joint-title farmer. However,

POLITICAL  CONSTITUTION OF THE  UNITED  MEXICAN  STATES  
 

87 
this kind of proceedings shall be admissible to their benefit. Waiving or express consent shall not be
accepted when the claimed acts affect the community’s rights, unless waiving or express consent are
agreed by the General Assembly of the farming cooperative.

III. The constitutional adjudication against rulings pronounced by judicial, administrative or labor
courts shall be admissible only in the following cases:

(Reformed by the decree published on June 6, 2011)
a) Against final rulings, binding judgments or resolutions that end the trial, no matter if infringement is
committed by such rulings, binding judgments or resolutions, or during the proceeding affecting the
plaintiff’s defense and the verdict. Regarding the constitutional adjudication mentioned in this
subdivision and in the section V of this article, the specialized circuit court shall decide on all
infringements to the proceedings and the corrections to the brief, establishing the terms for the new
ruling. If such violations were not reported in the first constitutional adjudication, and the specialized
court did not decided on the subject, then they cannot be invoked in a second constitutional
adjudication.

The party who has obtained a favorable ruling, as well the party who has legal interest that the act in
question persists, can file a constitutional adjudication in addition to the one filed by any of the parties
involved in the trial that generated the challenged act. The law shall determine the procedure and
requirements to file such trial.

For the constitutional adjudication admissibility, first the plaintiff must exhaust the ordinary
instruments provided by the applicable law, which may be suitable to modify or revoke the final
sentence, binding judgment or ruling, except for the cases when the law allows plaintiff to waive such
resources.

Violations to the procedural law should be invoked when challenging the final rulings, binding
judgments or resolutions that end the trial, provided that the plaintiff has challenged them through the
ordinary instruments. However, this requirement does not apply to the constitutional adjudication filed
against acts which affect the rights of minors or disabled persons, or affect the marital status or the
family’s order and stability, or the criminal acts filed by the defendant.

b) Against acts during a trial which enforcement would render them impossible to restitute, provided
that all applicable appeals have been exhausted.

c) Against acts affecting persons who are not involved in the trial.

(Reformed by the decree published on June 6, 2011)
IV. Regarding the administrative matter, the constitutional adjudication is accepted also against rulings
pronounced by other authorities, different to the judicial, administrative and labor courts, which caused
irreparable offence. It is necessary to exhaust these means of impugnment, provided that the effects of
such acts have been suspended by the court or by the plaintiff through the appropriate legal instrument.
In this case, the constitutional adjudication shall have the same scope than the one indicated by the
statutory law, and the requirements will be the same as required to grant the final suspension. Also, the

POLITICAL  CONSTITUTION OF THE  UNITED  MEXICAN  STATES  
 

88 
term shall not be greater than the one established for provisional suspension, regardless of whether the
act may be suspended or not, according to the law.

It is not necessary to exhaust such means of impugnment when the challenged act has no grounds, or
when only direct violations to this Constitution are argued.

(Reformed by the decree published on June 6, 2011)
V. The constitutional adjudication against final sentences, binding judgments or rulings that end the
trial, shall be filed with the competent specialized circuit court, according to the law, in the following
cases:

a) Relating to criminal matter, against final rulings pronounced by federal, ordinary or military courts.

b) Relating to administrative matter, when private persons challenge final sentences or rulings
pronounced by administrative or judicial courts, provided that such sentences or rulings are not
repairable through a legal instrument, trial or any other ordinary means.

c) Relating to civil matter, against final sentences pronounced in federal trials, or in federal or local
mercantile trials, or in trials for common crimes.

In federal civil cases, sentences may be challenged through the constitutional adjudication by any of the
interested parties, even the Federal Government, in defense of its pecuniary interests.

d) Relating to labor issues, when the constitutional adjudication challenges binding judgments
pronounced by a federal or local Commission for Conciliation and Arbitration, or by the Federal Court
of Conciliation and Arbitration for public employees.

The Supreme Court of Justice may hear direct constitutional adjudications that are important or
transcendental, by its own motion or by motion justified and submitted by a specialized circuit court or
by the Attorney General.

(Reformed by the decree published on June 6, 2011)
VI. The Statutory Law shall indicate the procedure and conditions to be met by the specialized circuit
courts and the Supreme Court in order to pronounce a ruling relating to section V of this Article.

(Reformed by the decree published on June 6, 2011)
VII. The constitutional adjudication against acts or omissions committed during a trial, in the trial
context or after that the trial, or against acts that affect persons who are not involved in the trial, or
against general laws or administrative authority’s acts or omissions, shall be lodged before the district
judge having jurisdiction over the place where the harmful actions have been committed or have been
tried to be committed. The procedure for such constitutional adjudication is as follows: 1) authority’s
report, 2) a hearing, 3) receipt of evidence provided by the interested parties, and 4) argument hearing.
The sentence shall be pronounced in the hearing.

VIII. The sentences pronounced as a result of a constitutional adjudication by a district judge or a
unitary circuit court may be reviewed. Such review shall be lodged before the Supreme Court of
Justice:

general provisions.

transcendental, by its own motion or by motion justified and submitted by a specialized circuit court or
by the Attorney General.

In all other cases, reviews shall be lodged before a specialized circuit court, which sentence shall be
final and shall not admit any further review.

(Reformed by the decree published on June 6, 2011)
IX. Regarding the direct constitutional adjudication, the review resource is appropriate to challenge the
sentences concerning the unconstitutionality of general provisions, or make a direct interpretation of a
constitutional provision, or failed to rule on these issues, provided that the Supreme Court of Justice
considers that such rulings create an important and transcendent criterion. In the constitutional
adjudication, only the constitutional issues shall be analyzed.

(Reformed by the decree published on June 6, 2011)
X. Claimed acts may be suspended in the cases and under the terms established by law. For this
purpose, the judge shall take into account the correct law and the public interest.

Regarding criminal matter, such suspension shall be applied while notifying the constitutional
adjudication lodged. Regarding civil, mercantile and administrative matters, such suspension shall be
applied when the plaintiff pays a bail, which shall be used to pay for the damages caused by the
suspension to a third party. Such suspension shall be void if the other party pays an indemnity bond in
order to assure reinstallment of the situation as if the constitutional adjudication has been granted.

(Reformed by the decree published on June 6, 2011)
XI. The direct constitutional adjudication shall be lodged before the authority responsible, which shall
rule on the suspension. In other cases, suspension shall be filed with the district court or the unitary
circuit court, which shall rule on suspension, or with the state courts where allowed by law.

XII. Appeals against violations to the constitutional rights provided under articles 16, related to
criminal matter, 19 and 20, shall be filed with the superior court standing directly above the court that
committed the infringement, or with the appropriate district judge or unitary circuit court. The rulings

this article.

authority responsible, then the law shall define the appropriate judge or court to lodge the constitutional
adjudication. Such judge or court can suspend temporarily the challenged act in accordance with the
law.

(Reformed by the decree published on June 6, 2011)
XIII. In the event that specialized courts of the same circuit defend contradictory criteria regarding
constitutional adjudication under their jurisdiction, then the Attorney General, the specialized circuit
courts, their members, the district judges or the parties can report this contradiction to the appropriate
circuit court, which shall decide which argument shall prevail as legal precedent.

In the event that circuit courts belonging to different circuits, or the specialized circuit courts belonging
to the same circuit, or the circuit courts of the same circuit with different specialization defend
contradictory criteria, then the ministers of the Supreme Court of Justice of the Nation, the circuit
courts or the bodies mentioned in the previous paragraph can report this contradiction to the Supreme
Court of Justice, so that the Plenary Meeting or the respective courtroom decides which argument shall
prevail.

In the event that the courtrooms belonging to the Supreme Court of the Nation defend contradictory
criteria in the constitutional adjudications under their jurisdiction, then the ministers of the Supreme
Court of Justice of the Nation, the specialized circuit courts, their members, the district judges, the
Attorney General or the parties can report this contradiction to the Supreme Court of Justice, so that the
Plenary Meeting or the respective courtroom decides which argument shall prevail.

Rulings pronounced by the Plenary Meeting of the Supreme Court of Justice or by one of its
courtrooms, or by the circuit courts according to the previous paragraphs, shall only establish
jurisprudence. They shall not affect the specific legal situations derived from the sentences pronounced
in the trials where contradictory legal precedents arose.

(Repealed by the decree published on June 6, 2011)
XIV. Repealed

XV. The Attorney General, or the federal public prosecutor appointed by him/her, shall be an interested
party in all constitutional adjudications. However, they can abstain from intervening when they
consider that the case has not public interest.

(Reformed by the decree published on June 6, 2011)
XVI. If the authority responsible fails to enforce the sentence pronounced in the constitutional
adjudication, but such failure is justified, then the Supreme Court of Justice of the Nation shall grant
the authority responsible a reasonable term to enforce the sentence, according to the procedure
provided by the law. This term may be extended at the request of the authority responsible. If failure to
observe the sentence is not justified, or the term has expired, then the Supreme Court of Justice shall
separate the head of the authority responsible from office and bring him/her to trial before the
appropriate district judge. This will apply also to the superior of the authority responsible if he/she is
liable, as well as to the previous heads of the authority responsible, if they failed to enforce the
sentence.
