Scope and Applicability of Title Four (Article 1415)

Article 1415 establishes the foundational scope of Title Four, specifying its application to national and international commercial arbitration where the seat of arbitration is within Mexican territory. This article also carves out crucial exceptions, recognizing the supremacy of international treaties to which Mexico is a party and other specific laws that may dictate different procedures or declare certain disputes non-arbitrable.

Furthermore, it highlights that certain provisions, specifically Articles 1424, 1425, 1461, 1462, and 1463, retain their applicability even if the arbitration takes place outside Mexico. This ensures a degree of legal consistency and recognition for specific aspects of arbitration, regardless of the geographical seat of the proceedings.

Article 1415 .- The provisions of this Title shall apply to national commercial arbitration, international and where the place of arbitration is in the national territory, except as provided in international treaties that Mexico is a party or other laws that establish a different procedure or provide that certain disputes are not arbitrable. The provisions of Articles 1424, 1425, 1461, 1462 and 1463, will apply even if the place of arbitration is outside the country.

Key Definitions in Commercial Arbitration (Article 1416)

Article 1416 is critical as it provides precise definitions for key terms used throughout Title Four, ensuring clarity and consistent interpretation. These definitions are essential for understanding the nature and scope of commercial arbitration under Mexican law.

  • Arbitration Agreement: This is defined as the explicit agreement between parties to submit all or specific disputes, arising from a defined legal relationship (contractual or not), to arbitration. It can be an arbitration clause within a contract or a standalone agreement.
  • Arbitration: Refers to any commercial arbitration, irrespective of whether a permanent arbitral institution is involved. This broad definition encompasses both institutional and ad hoc arbitrations.
  • International Arbitration: This designation is applied when parties have their places of business in different countries at the time of the agreement, or when the place of arbitration, performance, or closest connection to the dispute is outside the parties' country of establishment. Specific rules apply if a party has multiple establishments or no establishment.
  • Costs: A detailed breakdown of what constitutes "costs" in arbitration, including arbitral tribunal fees, travel expenses, expert advice, witness expenses (if approved), legal representation costs for the successful party (if claimed and deemed reasonable), and fees of the appointing institution.
  • Tribunal: Simply defined as the arbitrator or arbitrators appointed to decide a dispute.

Article 1416 .- For purposes of this title shall apply:

I. - Arbitration agreement, the agreement by the parties to submit to arbitration all or certain disputes which have arisen or may arise between them in respect of a defined legal relationship, whether contractual or not. The arbitration agreement may take the form of an arbitration clause in a contract or form a separate agreement;

II .- Arbitration, any arbitration of commercial, regardless of whether or not a permanent arbitral institution to which is carried out;

III .- International arbitration, one in which: a) The parties at the time of conclusion of the arbitration agreement have their places in different countries, or b) The place of arbitration, particularly in the arbitration agreement or under it, the place of performance of a substantial part of the obligations of the business relationship or the place with which the object of the dispute is closer, is located outside the country in which the parties have their establishment. For purposes of this section, if any of the parties have more than one establishment, the place of business is that you keep a closer relationship with the arbitration agreement, and if a party has no place, will be considered habitually resident ;

IV .- Costs, fees of the arbitral tribunal, the costs of travel and other expenses incurred by the arbitrators, costs of expert advice or other assistance required by the arbitral tribunal, travel and other expenses incurred by witnesses, if they are approved by the arbitral tribunal; cost of legal representation and assistance of the successful party if such costs were claimed during the proceedings, and only to the extent that the arbitral tribunal determines that the amount is reasonable, and fees and expenses of the institution has appointed the arbitrators;

V. - Tribunal, the arbitrator or arbitrators to decide a dispute.

Interpretation and Application of Provisions (Article 1417)

Article 1417 provides guidelines for interpreting specific provisions within Title Four. It clarifies that when a party has the right to decide freely on a matter, this power can extend to authorizing a third party, including an institution, to make that decision, with the exception of Article 1445.

It also specifies that references to "agreement between the parties" include all provisions of the arbitration rules agreed upon. Furthermore, a "lawsuit" implicitly includes a counterclaim, and a "defense" applies to the answer to a counterclaim, unless otherwise specified in certain articles. This ensures a consistent approach to procedural terminology.

Article 1417 .- Where a provision of this title:

I. - Let the party the right to decide freely on a matter, that power will involve authorizing a third party, including an institution, to take the decision in question, except as provided in Article 1445;

II .- It concerns an agreement between the parties, shall be included in that agreement, all provisions of the rules of arbitration agreement, where appropriate, forward;

III .- It refers to a lawsuit, it also applies to a counterclaim, and when it refers to a defense shall also apply to the answer to the counterclaim, except as provided in Section I of Article 1441 and paragraph a) of section II of Article 1449. The foregoing is without prejudice to the decision of the arbitrator jurisdiction to hear the claim and counterclaim.

Notices and Calculation of Time Limits (Articles 1418-1419)

Articles 1418 and 1419 lay down the rules for effective communication and the precise calculation of deadlines within the arbitration process. These provisions are crucial for maintaining procedural fairness and ensuring that all parties are properly informed and have adequate time to respond.

Commercial Code Mexico: Title Four Commercial Arbitration Overview

Detailed legal documents are central to the arbitration process.

Article 1418 specifies that, unless otherwise agreed, written communications are deemed received when delivered to the addressee's place of business, habitual residence, or mailing address. If these locations cannot be found after reasonable inquiry, delivery to the last known establishment, residence, or mailing address via registered mail or other proof-of-delivery means is considered valid. It explicitly states these rules do not apply to communications in court proceedings.

Article 1419 details the calculation of deadlines: periods begin the day after receipt of a notice. If the last day is a holiday or non-working day at the recipient's location, the period extends to the next working day. Holidays within the period are included in the calculation.

Article 1418 .- In reporting and calculation of deadlines will be as follows:

I. - Unless otherwise agreed by the parties: a) Be considered written communications received have been delivered to the addressee or has been delivered at his place, habitual residence or mailing address, in the event that is not obtained after reasonable inquiry the location of any of these places, deemed received any written communication sent to the latter establishment, residence or mailing of the recipient, by registered letter or any other means affording evidence of attempted delivery; b) The communication is deemed received on the day on which it is so delivered.

II .- The provisions of this Article shall not apply to communications in court proceedings.

Article 1419 .- For purposes of calculating deadlines established in this title, that period starts to run from the day following the date of receipt of a notice, notification, communication or proposal. If the last day of such period is an official holiday or not working at the place of residence or place of business of the addressee, the period is extended until the next working day. Other official holidays or non-business occurring during the course of time are included in calculating the period.

Waiver of Right to Object (Article 1420)

Article 1420 introduces the principle of waiver, a critical aspect of procedural efficiency in arbitration. It stipulates that if a party proceeds with arbitration knowing that a provision of Title Four (from which parties may derogate) or an arbitration agreement requirement has not been complied with, and fails to state an objection without undue delay (or within an agreed timeframe), that party is deemed to have renounced their right to challenge such non-compliance later.

This provision encourages parties to raise procedural objections promptly, preventing them from strategically reserving such objections until a later, more opportune moment to disrupt the proceedings or challenge an unfavorable award. It reinforces the idea of good faith and active participation in the arbitration process.

Article 1420 .- If one part goes to arbitration knowing that it has complied with a provision of this title which the parties may derogate or any requirement for arbitration agreements and stating his objection to such non-compliance without delay justified or if a term is expected to do so and do so means renounced their right to challenge.

Judicial Intervention in Arbitration (Articles 1421-1422)

Articles 1421 and 1422 define the boundaries of judicial intervention in commercial arbitration, emphasizing the principle of minimal court involvement while outlining specific instances where such intervention is necessary and appropriate. This balance is key to preserving the autonomy of arbitration while ensuring legal oversight when required.

Article 1421 establishes the general rule: unless otherwise provided, matters governed by Title Four do not require judicial intervention. This underscores the self-contained nature of arbitration as a dispute resolution mechanism. Article 1422 specifies that when judicial intervention is required, jurisdiction falls to the federal trial judge or the common order judge of the place where the arbitration takes place.

For arbitrations seated outside Mexico, the same judges (federal trial judge or common jurisdiction judge at the debtor's domicile, or where assets are located) will handle the recognition and enforcement of the arbitral award. This ensures that foreign awards can be effectively enforced within Mexico.

Article 1421 .- Except as otherwise provided in the matters governed by this Title shall not require judicial intervention.

Article 1422 .- When judicial intervention is required shall have jurisdiction in the federal trial judge or the common order of the place where the arbitration takes place. When the place of arbitration is outside the country, meet the recognition and enforcement of the award the trial judge or of a common federal jurisdiction, the domicile of the debtor or, failing that, the location of the property .

The Arbitration Agreement (Articles 1423-1425)

The arbitration agreement is the cornerstone of any arbitration proceeding, and Articles 1423 to 1425 detail its formal requirements and the judicial treatment it receives. These provisions ensure the validity and enforceability of the parties' choice to arbitrate.

Article 1423 mandates that the arbitration agreement must be in writing. This requirement can be satisfied by a document signed by the parties, an exchange of various telecommunications (letters, telex, telegram, facsimile) that provide a record, or an exchange of statements of claim and defense where one party alleges the agreement and the other does not deny it. A reference in a contract to a document containing an arbitration clause also constitutes a valid agreement, provided the contract is in writing and the reference makes the clause part of the contract.

Commercial Code Mexico: Title Four Commercial Arbitration Overview

Intertwined threads represent the complex yet structured nature of dispute resolution agreements.

Article 1424 addresses the judge's role when a dispute subject to an arbitration agreement is brought before a court. The judge must refer the parties to arbitration if requested by any party, unless the agreement is found to be void, inoperative, or impossible to implement. Importantly, the arbitral proceedings can commence or continue, and an award can be made, even while the matter is pending before the judge.

Article 1425 permits parties to request interim protective measures from a judge, either before or during the arbitration proceedings, even if an arbitration agreement exists. This ensures that urgent protection for assets or evidence can be obtained without waiting for the arbitration to conclude.

Article 1423 .- The arbitration agreement shall be in writing and recorded in a document signed by the parties or in an exchange of letters, telex, telegram, facsimile or other means of telecommunication which provide a record of the agreement, or an exchange of statements of claim and defense in which the existence of an agreement is alleged by one party and not denied by another. The reference in a contract to a document containing an arbitration clause constitutes an arbitration agreement provided that the contract is in writing and the reference is such that clause part of the contract.

Article 1424 .- The judge to submit a dispute over a matter that is the subject of an arbitration agreement, refer the parties to arbitration in the time requested by any of them, unless they are satisfied that the agreement is void, inoperative or implementation impossible. If you have filed the action referred to above, may nevertheless be commenced or continue the arbitral proceedings and make an award while the matter is pending before the judge.

Article 1425 .- Even if there is an arbitration agreement the parties may, prior to the arbitration proceedings or during, ask the judge to adopt interim measures of protection.

Composition of the Arbitral Tribunal (Articles 1426-1427)

The composition of the arbitral tribunal is a critical aspect, as the arbitrators are responsible for adjudicating the dispute. Articles 1426 and 1427 provide flexibility for parties to determine the number and appointment procedure of arbitrators, while also establishing default rules and judicial safeguards.

Article 1426 states that parties are free to determine the number of arbitrators. In the absence of such an agreement, a single arbitrator will be appointed. This provides a default mechanism to prevent deadlock.

Article 1427 outlines the appointment process. Parties can freely agree on the procedure, and an arbitrator's nationality generally does not preclude their appointment. If no agreement is reached, specific default procedures apply: for a sole arbitrator, the judge appoints upon request; for three arbitrators, each party appoints one, and those two appoint the third. If a party fails to appoint or the two arbitrators cannot agree, the judge makes the appointment upon request.

The article also covers situations where an agreed appointment procedure fails, allowing either party to ask the judge for necessary measures. Any judicial decision on appointment is final. When making appointments, the judge must consider the parties' agreed conditions for the arbitrator and ensure the appointment of an independent and impartial individual. For sole or third arbitrators, the judge should also consider appointing someone of a different nationality from the parties to enhance perceived neutrality.

Article 1426 .- The parties may freely determine the number of referees. Failing such agreement, shall be one arbitrator.

Article 1427 .- For the appointment of referees will be the following:

I. - Unless otherwise agreed by the parties, the nationality of a person shall not preclude acting as arbitrator.

II .- Notwithstanding the provisions of Sections IV and V of this Article, the parties may freely agree on the procedure for appointing arbitrators.

III .- Failing such agreement: a) In an arbitration with a sole arbitrator if the parties fail to agree on the appointment of the arbitrator shall be appointed at the request of either party, by the judge; b) In an arbitration with three arbitrators, each party shall appoint one arbitrator and the two arbitrators so appointed shall appoint the third, if a party fails to appoint an arbitrator within thirty days of receipt of a request from the other party to do so, or if the two arbitrators fail to agree on the third arbitrator within thirty days from the date of his appointment, the appointment shall be made at the request of either party, by the judge;

IV .- When an appointment procedure agreed upon by the parties, one fails to act as required under such procedure, or the parties or two arbitrators can not reach an agreement under that procedure, or a third party, including an institution not fulfill any function entrusted to it under such procedure, either party may ask the judge to take the necessary measures, unless the agreement on the appointment procedure provides other means for achieving this and

V. - Any decision on a matter entrusted to the judge in fractions III or IV of this Article shall be final. In appointing an arbitrator, the judge shall give due regard to the conditions required of the arbitrator set forth in the agreement between the parties and take steps to secure the appointment of an independent and impartial arbitrator. In the case of a sole or third arbitrator shall take into account also the advisability of appointing an arbitrator of a nationality other than the parties.

Impartiality, Independence, and Challenge of Arbitrators (Articles 1428-1429)

The integrity of the arbitral process hinges on the impartiality and independence of the arbitrators. Articles 1428 and 1429 establish stringent requirements for disclosure and provide mechanisms for challenging arbitrators who fail to meet these standards.

Article 1428 mandates that any person approached for a possible appointment as an arbitrator must disclose any circumstances likely to give rise to justifiable doubts about their impartiality or independence. This duty of disclosure continues throughout the arbitral proceedings. An arbitrator can only be challenged if such justifiable doubts exist or if they lack the qualities agreed upon by the parties. A party can challenge an arbitrator they appointed only for reasons they became aware of after the appointment.

Article 1429 allows parties to freely agree on the challenge procedure. In the absence of such an agreement, a party wishing to challenge an arbitrator must send a letter to the arbitral tribunal within fifteen days of becoming aware of the tribunal's constitution or the challenging circumstances, stating the grounds for disqualification. If the challenged arbitrator does not withdraw or the other party does not accept the challenge, the arbitral tribunal decides on the matter.

If the challenge is unsuccessful, the challenging party can request a judge to rule on its provenance within thirty days of notification of the rejection. This judicial decision is final. Importantly, the arbitral tribunal, including the challenged arbitrator, may continue the proceedings and make an award while such a judicial request is pending, ensuring the process is not unduly delayed.

Article 1428 .- A person who communicates with his possible appointment as an arbitrator shall disclose any circumstances likely to give rise to justifiable doubts as to his impartiality or independence. The referee from the time of appointment and throughout the arbitral proceedings without delay disclose any such circumstances to the parties unless it has already been made of his knowledge. An arbitrator may be challenged only if circumstances exist that give rise to justifiable doubts as to his impartiality or independence, or if it possesses the qualities agreed by the parties. A party may challenge an arbitrator appointed by him or in whose appointment he has participated, only for reasons of which he has made aware after the appointment.

Article 1429 .- The parties may freely agree on the procedure for challenging an arbitrator. Failing agreement, the party wishing to challenge an arbitrator shall send the arbitral tribunal within fifteen days after the date of becoming aware of its constitution or circumstances giving rise to justifiable doubts as to the arbitrator's impartiality or independence, or if you do not have the qualities agreed a letter which sets the grounds for disqualification. Unless the challenged arbitrator withdraws from his office or the other party accepts the challenge, the arbitral tribunal shall decide on it. If not successful the challenge filed in the preceding paragraph, the challenging party may request the judge within thirty days of notification of the decision rejecting the challenge, ruling on its provenance, a decision will be final. While that request is pending, the arbitral tribunal, including the challenged arbitrator, may continue the arbitral proceedings and make an award.

Termination and Replacement of Arbitrators (Articles 1430-1431)

Articles 1430 and 1431 address situations where an arbitrator's mandate terminates and how a replacement is appointed. These provisions are crucial for ensuring the continuity and completion of the arbitration process even if an arbitrator becomes unavailable.

Article 1430 specifies that an arbitrator ceases to hold office if they are prevented (in fact or by law) from exercising their functions, or fail to exercise them within a reasonable time. This termination occurs if the arbitrator resigns or if the parties agree to it. If there is disagreement, either party can ask a judge to order the termination, and this judicial decision is final.

Article 1431 ensures that if an arbitrator's mandate terminates under Article 1429 (challenge) or 1430 (incapacity, resignation, agreement, or judicial order), a replacement arbitrator must be appointed following the exact same procedure used for the initial appointment. This maintains consistency with the parties' original agreement or the default rules.

Article 1430 .- When an arbitrator is prevented in fact or by law to exercise his functions or for other reasons not exercised within a reasonable time, cease to hold office if you resign or if the parties agree on the termination. If there is disagreement, either party may ask the judge terminates the order, decision is final.

Article 1431 .- If an arbitrator ceases to hold office under the provisions of Articles 1429 or 1430, resignation, removal by agreement of the parties or termination of your order for any other cause, shall appoint a replacement following the same procedure by was appointed an arbitrator to be replaced.

Jurisdiction of the Arbitral Tribunal (Articles 1432-1433)

The arbitral tribunal's power to rule on its own jurisdiction, known as "competence-competence," is a fundamental principle of arbitration. Articles 1432 and 1433 codify this principle and define the tribunal's authority regarding interim measures.

Article 1432 explicitly grants the arbitral tribunal the power to rule on its own jurisdiction, including any objections concerning the existence or validity of the arbitration agreement. This article also establishes the principle of severability, meaning that an arbitration clause forming part of a contract is considered independent of other contract terms. Therefore, a decision by the tribunal declaring a contract void does not automatically invalidate the arbitration clause.

Objections to the tribunal's jurisdiction must be raised no later than the time of the response to the claim. Raising such an objection is not precluded by having appointed an arbitrator or participated in their appointment. Objections that the tribunal has exceeded its mandate must be raised as soon as the matter alleged to be beyond its mandate arises during the proceedings. The tribunal may, however, admit an exception if it considers the delay justified.

The arbitral tribunal can rule on a jurisdictional plea either as a preliminary question or in the final award on the merits. If it rules on jurisdiction prior to the merits and declares itself competent, any party can request a judge to definitively resolve the matter within thirty days of notification, and this judicial resolution is final. While such an application is pending, the arbitral tribunal may continue the proceedings and make an award.

Article 1433 allows the arbitral tribunal, unless otherwise agreed by the parties, to order interim measures of protection at the request of one of the parties. The tribunal may also require any party to provide sufficient security in relation to these measures, ensuring their effectiveness and preventing abuse.

Article 1432 .- The arbitral tribunal may rule on its own jurisdiction, including any objections concerning the existence or validity of the arbitration agreement. To this end, the clause which forms part of a contract is considered as an agreement independent of the other terms of the contract. The decision of an arbitral tribunal declaring void a contract, not by that fact alone will entail the nullity of the arbitration clause. The plea that the arbitral tribunal shall be raised not later than the time of the response. The party is not precluded from raising such plea by the fact that he has appointed an arbitrator or participated in the appointment. A plea that the arbitral tribunal has exceeded its mandate, shall be raised as soon as they arise during the arbitral proceedings the matter alleged to be beyond its mandate. The arbitral tribunal may, in any case, admit an exception if it considers presented after the delay justified. The arbitral tribunal may rule on a plea referred to in the above course or award on the merits. If prior to rule upon the merits, the tribunal has jurisdiction, any party within thirty days after the date on which this decision is notified, request the judge ultimately resolved, resolution will be final. Pending such application, the arbitral tribunal may continue the proceedings and make an award.

Article 1433 .- Unless otherwise agreed by the parties, the arbitral tribunal may, at the request of one of them, order the adoption of the precautionary measures necessary in respect of disputed. The arbitral tribunal may require any party to provide sufficient in relation to these measures.

Conduct of Arbitral Proceedings (Articles 1434-1439)

Chapter V, starting with Article 1434, outlines the fundamental principles guiding the conduct of arbitral proceedings, emphasizing fairness, party autonomy, and the tribunal's discretion in procedural matters. These articles ensure that arbitration is conducted efficiently and equitably.

Article 1434 mandates equal treatment for all parties and a full opportunity for each to assert their rights. This principle of due process is paramount. Article 1435 grants parties the freedom to agree on the procedure the arbitral tribunal will follow. In the absence of such an agreement, the tribunal can conduct the arbitration as it deems appropriate, subject to the provisions of Title Four. This includes determining the admissibility, relevance, and value of evidence.

Article 1436 allows parties to freely determine the place of arbitration. If they do not agree, the tribunal will determine it based on the circumstances, including the convenience of the parties. However, the tribunal can meet at any location it deems appropriate for consultations, hearings, or inspections, unless the parties agree otherwise.

Article 1437 specifies that, unless parties agree otherwise, arbitration proceedings commence when the respondent receives the request for that dispute to arbitration. Article 1438 permits parties to agree on the language(s) to be used. Failing agreement, the tribunal determines the language, which applies to all submissions, hearings, awards, and communications. The tribunal may also require translations of documentary evidence.

Finally, Article 1439 requires the claimant to state the facts, points at issue, and benefits claimed within an agreed or tribunal-determined period, and the respondent must cover all points raised in the complaint. This sets the stage for the formal exchange of pleadings.

Article 1434 .- The parties should be treated equally and given to each one full opportunity to assert their rights.

Article 1435 .- Subject to the provisions of this title, the parties are free to agree the procedure is to adjust the arbitral tribunal in proceedings. Failing agreement, the arbitral tribunal may, subject to the provisions of this title, conduct the arbitration as it considers appropriate. The power conferred upon the arbitral tribunal includes the power to determine the admissibility, relevance and value of the evidence.

Article 1436 .- The parties may freely determine the place of arbitration. In case of no agreement, the court shall determine the place of arbitration in the circumstances of the case, including the convenience of the parties. Notwithstanding the preceding paragraph, the arbitral tribunal may, unless otherwise agreed by the parties, meet at any place it considers appropriate for consultation among its members, hear the parties, witnesses or experts, or for inspection of goods, other property or documents.

Article 1437 .- Unless the parties otherwise agreed, the arbitration proceedings with respect to a particular dispute commence on the date the defendant has received the request for that dispute to arbitration.

Article 1438 .- The parties may freely agree on the language or languages ​​to be used in the arbitral proceedings. Failing such agreement, the court shall determine the language to be used in the proceedings. This agreement or determination shall apply, unless otherwise agreed, all submissions of the parties, any hearing and any award, decision or other communication issued by the arbitral tribunal. The arbitral tribunal may order that any documentary evidence shall be accompanied by a translation into one of the languages ​​agreed upon by the parties or determined by the arbitral tribunal.

Article 1439 .- Within the period agreed by the parties or determined by the arbitral tribunal, the actor must state the facts underlying the claim, the points at issue and claiming benefits, and the defendant must cover all points raised in the compla...
