I. Normative Architecture - Who Governs the Bank?

Spain has a multi-layered system:

1. EU Level - The paradigm shift

• SSM Regulation 1024/2013: ECB is direct supervisor of Significant Institutions - Santander, BBVA, CaixaBank, Sabadell, Bankinter, Unicaja. Banco de España is supervisor for Less Significant Institutions, under ECB oversight.
• CRD IV/V and CRR: transposed via Real Decreto-ley 14/2013 and Ley 10/2014, de 26 de junio, de ordenación, supervisión y solvencia de entidades de crédito (LOSSEC) and RD 84/2015.

2. National Level - LOSSEC is the core

• Art. 26-38 Ley 10/2014: Corporate governance requirements: Board suitability (idoneidad), collective suitability, honesty, knowledge, independence, time commitment. At least 1/3 independent directors, separation of Chairman/CEO, mandatory committees - Nomination, Remuneration, Risk, Audit.
• Art. 52-53 Ley 10/2014: Supervision of governance: Banco de España shall supervise systems, strategies, procedures and mechanisms, and corporate governance and remuneration. Very serious infringement under Art. 100 for breach of governance/remuneration.
• Ley 26/1988 de Disciplina e Intervención (still applied for sanctions), Ley de Sociedades de Capital (LSC) Art. 225-232 duty of diligence and loyalty, Circular 2/2016 del Banco de España on suitability, and Código de Buen Gobierno de Sociedades Cotizadas CNMV 2020 (comply or explain).

Critical jurisprudence asks: does this formal architecture prevent capture? Spanish doctrine (García Mandaloniz, Recamán) argues it formalizes but does not depoliticize.

II. Critical Pillars Analysed by Spanish Doctrine

1. From Shareholder Primacy to Stakeholder Risk: Traditional LSC says directors act for interés social. Banking law says they must act for financial stability. Conflict resolved by Art. 91 CRD IV - prudent management overrides shareholder value.

2. The Cajas Problem: Governance failure of savings banks where political parties, unions and regional governments sat on boards without banking expertise or capital at risk. Law 26/2013 de Cajas transformed them into banking foundations.

3. Material Transparency vs Formal Disclosure: Core contribution of Spanish Supreme Court.

III. Leading Case Laws - The Jurisprudential Canon

1. The Transparency Doctrine - Floor Clauses

Tribunal Supremo, STS 241/2013, 9 May 2013 - Cláusulas Suelo
The Supreme Court held that floor clauses in mortgages (minimum 2-3% interest even if Euribor falls) were abusive because they lacked transparencia material. It is not enough to be grammatically clear; the consumer must understand the economic burden in the contract's overall architecture. This created double transparency control: formal and material.

Consequence - STJUE 21 Dec 2016, Joined Cases C-154/15 Gutiérrez Naranjo
The Spanish Supreme Court limited retroactivity to May 2013 for legal certainty. CJEU overruled: EU Directive 93/13 requires full retroactive nullity. Critical reading: national courts protected banking solvency over consumer restitution.

2. The IPO Fraud - Bankia Case - Governance of Information

STS 23/2016 and STS 24/2016, 27 Jan and 3 Feb 2016 - Bankia IPO
Supreme Court ruled Bankia's 2011 IPO prospectus contained "serious inaccuracies" regarding its true financial situation. Small investors' purchase was annulled for error vicio. Bankia had to provision €1.84bn to reimburse retail investors. Jurisprudential principle: Board's duty of accurate accounting information (Art. 25 Código de Comercio) is a corporate governance obligation enforceable by investors, not just regulator.

This is the largest case of prospectus liability in Spain.

3. The Black Cards - Misappropriation and Duty of Loyalty

Audiencia Nacional 23/2017 and Tribunal Supremo STS 487/2018, 3 Oct 2018 - Caso Tarjetas Black (Caja Madrid/Bankia)
63 directors including ex-IMF head Rodrigo Rato used opaque corporate cards 2003-2012. Supreme Court upheld 4.5 years prison for Rato for misappropriation.

Ratio: Application of Art. 252 Código Penal and Art. 227 LSC - breach of duty of loyalty and proper management of corporate assets. Court held that governance systems that allow unmonitored discretionary expenses without board oversight or accounting control constitute a failure of internal control model - leading to corporate criminal liability under Art. 31 bis CP after 2010 reform.

4. Preferentes and IRPH - Structural Mis-selling

STS 626/2013, 17 Jan 2014 - Participaciones Preferentes CAM, STS 149/2020 IRPH
Supreme Court held IRPH (official index defined by law) could still be subject to transparency control because banks incorporated it via general conditions. For participaciones preferentes sold by Caixa, CAM, Popular, Court found banks violated MiFID suitability test - product designed for institutional investors sold to retail without adequate governance.

5. Resolution and Bail-in - Banco Popular

STS 210/2021 and Audiencia Nacional SAN 2022 - Banco Popular Resolution 7 June 2017
First application of BRRD/Ley 11/2015 in EU. Single Resolution Board wrote down shares and AT1/AT2 instruments to zero, sold to Santander for €1. Shareholders challenged. Supreme Court upheld resolution: financial stability and public interest prevail over property rights (Art. 33 CE) when entity is failing or likely to fail. Critical jurisprudence notes this ends Too-Big-To-Fail shareholder guarantee.

IV. Critical Conclusions for Spain

Spanish critical scholars (Alberto Ruiz Ojeda, Pablo Fernández) identify 4 lessons:

1. Law is pro-cyclical: Ley 10/2014 is robust ex-post but was weak ex-ante. Banco de España had powers before 2012 but did not use them against cajas.
2. Governance cannot be only procedural: Suitability tests fail if political appointment logic persists in foundations that control banks (Fundación La Caixa, Kutxabank).
3. Judicialization of banking governance: Since regulator failed, governance control has been outsourced to civil judges via transparency doctrine - 500,000 floor clause cases.
4. EU supremacy limits national protectionism: CJEU has repeatedly corrected Tribunal Supremo when it limited retroactivity to protect banking solvency.
