Extraordinary Appeal for Procedural Infringement in Spain: Requirements, Grounds and Procedure (2026)

# Extraordinary Appeal for Procedural Infringement: Requirements, Grounds and Procedure (2026)

The extraordinary appeal for procedural infringement (REP: recurso extraordinario por infracción procesal) allows the Supreme Court (Tribunal Supremo, Civil Chamber One) to review second-instance judgments where they have incurred infringements of procedural rules. It is governed by articles 468 to 476 of the LEC (Ley de Enjuiciamiento Civil, the Spanish Code of Civil Procedure).

1. Jurisdictional Framework: Supreme Court vs. Superior Courts of Justice

Current rule:

• TSJ (Tribunal Superior de Justicia, Regional Superior Court of Justice): hears the REP when the merits were governed by regional special civil law (Catalan, Balearic, Navarrese, Galician, Aragonese, Basque, or Valencian law)
• Supreme Court (Civil Chamber One): when the merits are governed by common civil law

Compatibility with cassation appeal: the REP may be filed jointly with a cassation appeal (recurso de casación). It is resolved first; if the infringement is upheld and the judgment annulled, the cassation appeal becomes moot.

2. Appealable Decisions (art. 468 LEC)

• Judgments of the Provincial Courts (Audiencias Provinciales) resolving appeals
• Orders (autos) of the Provincial Courts bringing proceedings to an end

Not available against first-instance judgments or against judgments of the Supreme Court or TSJ sitting as a court of sole instance.

3. Statutory Grounds (art. 469 LEC)

Ground 1: Jurisdiction and Competence

Infringements of rules on jurisdiction (national vs. international, civil vs. criminal/labour) or subject-matter/functional competence.

Ground 2: Rules Governing Judgments

• Incongruence: extra petita (awarding more than claimed), ultra petita, infra petita, omissive incongruence (failure to rule on a claim)
• Lack of reasoning (art. 218 LEC): absence of legal grounds or merely apparent reasoning
• Internal contradiction within the judgment

Ground 3: Legal Rules Governing Procedural Acts and Guarantees

The broadest and most frequently invoked:

• Violation of rules on evidence (admission, taking, and mandatory assessment of evidence)
• Infringement of the right to be heard (causing a defence deficit)
• Violation of rules on the burden of proof (art. 217 LEC)

Requirement of prejudice to the defence (art. 469.2 LEC): an infringement may only be invoked if the party had no opportunity to challenge it during the proceedings.

Ground 4: Violation of Article 24 of the Spanish Constitution

• Right to effective judicial protection (art. 24.1 CE): access to courts, ruling on the merits, congruence
• Right to a fair trial with all procedural guarantees
• Right to a defence and legal representation
• Right to use relevant means of proof

Distinction from constitutional amparo appeal: the REP on Ground 4 is a prerequisite to the amparo appeal; without exhausting the REP, a party cannot apply to the Constitutional Court (Tribunal Constitucional, TC) for violation of article 24 CE in civil proceedings.

4. Formal Requirements

Standing: any party whose claims were dismissed or who suffered the procedural infringement. The appellant must have timely protested the infringement (art. 469.2 LEC).

Time limit: 20 days from notification of the Provincial Court's judgment.

Amount in dispute: for Grounds 1 to 3, the proceedings must exceed €600,000 or involve an indeterminate amount. Ground 4 has no amount threshold.

Court deposit: €50 upon filing for admission (15th Additional Provisión of the LOPJ (Ley Orgánica del Poder Judicial), the Organic Law of the Judiciary).

5. Procedure (arts. 470–476 LEC)

Admission (art. 473 LEC): the Supreme Court may refuse to admit the appeal by order (auto) where it manifestly lacks legal foundation.

Ruling (art. 476 LEC):

• Grounds 1 and 2: the Supreme Court issues a new decisión
• Grounds 3 and 4: the Supreme Court annuls the decisión and remands the proceedings to the procedural stage at which the infringement occurred

6. Relevant Case Law

STS 18 January 2022: failure to rule on a plea of limitation raised and reiterated on appeal constitutes an infringement under Ground 2 (omissive incongruence).

STS 15 March 2021: a violation of the right to present evidence (Ground 4) requires that the excluded evidence be relevant and material to the outcome. An error in the free assessment of evidence is not a valid ground for the REP.

STS 3 November 2020: distinguishes between an error in the appraisal of evidence (not a valid REP ground) and a violation of the rules on burden of proof under art. 217 LEC (which is a valid ground).

STS 14 September 2023: a formal protest during oral proceedings is not required if the issue has been expressly contested in the written pleadings.

7. Practical Considerations

Prior protest is critical: upon any procedural infringement at first instance, make it expressly on the record at the time and in all subsequent written pleadings.

Do not confuse the REP with the cassation appeal: the REP does not permit review of the free assessment of evidence or the legal characterisation of the facts.

Amount in dispute as a filter: in proceedings below €600,000 where the infringement does not fall under article 24 CE, the REP is unavailable; the only remaining remedy is the amparo appeal, if article 24 CE has been violated.
