tration remaining the preferred method of ADR, given that this practice was already well established. 12.2 ADR Within the Legal System Although OL 1/2025 sets out multiple forms of ADR (see 3.1 Rules on Pre-action Conduct ), this does not repeal of specific legislation governing conciliation or mediation. OL 1/2025 itself includes references to such laws, such as Law 5/2012, of 6 July, on Mediation in Civil and Commercial Matters and Law 15/2015, of 2 July, on Voluntary Jurisdiction (Article 14 OL 1/2025). 12.3 ADR Institutions Spain has several institutions that offer and promote ADR. Aside from the Arbitration Tribunal of Barce- lona, the most relevant are located in Madrid and are focused on arbitration – the European Arbitration Association, Court of Arbitration of Madrid (CAM); the Civil and Commercial Court of Arbitration (CIMA); and the Spanish Court of Arbitration (CEA). On 16 October 2019, the establishment of the Inter- national Arbitration Centre of Madrid (CIAM) was announced. The CIAM is the result of the merger of the international activities of the three most prominent arbitration institutions in Spain – CAM, CIMA and the CEA. As of 1 January 2020, the CIAM is competent to administer two types of international arbitrations arising from new arbitration agreements: firstly, those arising from agreements in which the parties directly designate CIAM as the administering court, and sec- ondly, those arising from agreements between parties to submit to arbitration administered by CAM, CIMA or the CEA.

OL 1/2025 did not amend the 2003 Spanish Arbitra- tion Act but introduced co-ordination mechanisms between arbitration and other MASC procedures. Specifically, its Additional Provision Three provides for the creation of a public registry of MASC entities, which may include arbitration institutions accredited to administer or collaborate in pre-litigation resolution schemes. 13.2 Subject Matters Not Referred to Arbitration Arbitration in Spain only can extend to civil and private matters subject to the parties’ consent. It is under- stood that this limitation excludes arbitration in labour, administrative and criminal matters, as well as in civil issues involving public interest (family law, compe- tency, etc). 13.3 Circumstances to Challenge an Arbitral Award Arbitral awards in Spain may only be set aside (annulled) in very specific circumstances, if the chal- lenging party alleges and duly proves that: • the arbitration agreement does not exist or, if it does exist, is null and void; • the applicant has not been notified about the appointment of an arbitrator or about any order, or the applicant has not been able to exercise its rights; • the arbitrators have ruled on matters beyond the scope of their power; • the appointment of the arbitrators and/or the proceeding is in breach of the parties’ agreement or, failing the parties’ agreement, is contrary to the SAA;
