Organic Law 1/2025: Justice Efficiency and Its Criminal Impact in Spain
In this article
Key Takeaways
- Collegiate Courts of Instance
- Alternative dispute resolution
- Plea agreements: Art. 785, not 787
- Full digital justice
Organic Law 1/2025 replaces single-judge courts with Courts of Instance featuring specialised sections, generalises digital justice and expands the use of videoconferencing. For criminal defence, its most relevant effects are the reorganisation of the trial courts, fully digital processing and the retention of the investigation deadlines of Art. 324 LECrim. One frequent misunderstanding is worth clearing up: the plea agreement in the abbreviated procedure is entered at the preliminary hearing of Art. 785 LECrim and the Act sets no general ceiling in years; the nine-year figure is the scope of the abbreviated procedure itself (Art. 757 LECrim), not a cap on plea agreements. Its rollout is progressive between 2025 and 2027.

Organic Law 1/2025, of 2 January, on measures of efficiency of the Public Justice Service, together with the ordinary Law 1/2025 on Adequate Dispute Resolution Means, constitutes the most ambitious reform of the Spanish judicial structure in decades. Its rollout is progressive across 2025 and 2026 and directly impacts criminal defence. As criminal lawyers, we summarise the practical keys.
Courts of Instance: a New Judicial Organisation
The reform replaces the current single-judge courts with Courts of Instance, collegiate bodies with specialised sections. Each judicial district will have a single Court of Instance with a Civil Section, an Investigation Section, a Criminal Trial Section, a Violence Against Women Section, a Minors Section and a Prison Supervision Section. The rollout is phased: July 2025 (provincial capitals), 2026 (districts over 150,000 inhabitants), 2027 (the rest).
Adequate Dispute Resolution Means
Law 1/2025 generalises alternative dispute resolution (mediation, conciliation) as a procedural requirement in civil and commercial jurisdiction. In criminal matters, its impact is limited but relevant: criminal mediation remains voluntary, but the law expressly recognises its effects regarding the mitigating factor of repair of the harm (Art. 21.5 CP); it is expressly excluded in gender violence, terrorism and sexual offences against minors; As to plea agreements, a widespread misunderstanding should be cleared up: the plea in the abbreviated procedure is entered at the preliminary hearing of Art. 785 LECrim (as redrafted by this same Organic Law 1/2025, in force since 3 April 2025) and the Act sets no general ceiling in years — the nine-year figure is the scope of the abbreviated procedure (Art. 757 LECrim). The quantified incentive, the one-third reduction, is the one in Art. 801 LECrim before the duty court, reserved for offences carrying up to three years' imprisonment.
Investigation Deadlines and Digital Justice
Organic Law 1/2025 maintains the maximum investigation deadlines of Art. 324 LECrim (12 ordinary months, extendable). However, it introduces relevant procedural changes: full digitalisation of the procedure (processing, notifications and filings entirely electronic), preferred videoconferencing (Art. 731 bis LECrim) for the statements of witnesses and experts, the electronic judicial file accessible from the digital judicial portal, and automated deadlines. Access to the digital file requires the lawyer to monitor the procedure daily.
Changes to the Criminal Procedure Act
- Art. 776 LECrim: reinforcement of legal assistance for the detained person and the right to information.
- Art. 779 LECrim: extension of the early guilty plea in the abridged procedure.
- Art. 800 LECrim: the fast-track trial extends its scope with more flexible admission criteria.
- Art. 962 LECrim: reform of the minor-offence trial, now entirely remote save for exceptions.
- Appeals: reinforcement of the appeal against dismissal orders and simplification of the cassation appeal.
Impact on Defence Strategy
- Early specialisation: knowing the rollout schedule of the Court of Instance in each district allows anticipating which section will investigate.
- Early assessment of the plea agreement: weighing as soon as possible whether to plead and at which procedural stage. The quantified one-third reduction exists only under Art. 801 LECrim, before the duty court; outside that route, any reduction depends on what is negotiated over the legal classification and the mitigating factors.
- Strategic criminal mediation: in property offences or minor injuries, activating mediation facilitates the mitigating factor of repair (Art. 21.5 CP).
- Digital control of the procedure: implementing systems to monitor the electronic file daily and react within the strict deadlines.
- Videoconferencing as a tool: requesting a statement by video link for clients with difficulty travelling or resident abroad.

Frequently asked questions
What are the Courts of Instance created by Organic Law 1/2025?
They are collegiate judicial bodies that replace the former single-judge courts. Each judicial district will have a single Court of Instance with specialised sections (Investigation, Criminal Trial, Violence Against Women, Minors or Prison Supervision). The rollout is phased: July 2025 in provincial capitals, 2026 in districts of more than 150,000 inhabitants, and 2027 in the rest.
Up to what penalty can a plea agreement be entered?
The Act sets no general ceiling in years. The plea agreement in the abbreviated procedure is entered at the preliminary hearing of Art. 785 LECrim, with no quantitative limit of its own; the nine-year custodial threshold is the scope of the abbreviated procedure itself (Art. 757 LECrim), not a cap on the agreement. The quantified limit is in Art. 801 LECrim: the plea before the duty court in fast-track proceedings, with a one-third reduction, is available only for offences carrying up to three years' imprisonment and provided the reduced term does not exceed two years. Art. 787 LECrim, often cited in this context, no longer regulates plea agreements.
Do the investigation deadlines change under Organic Law 1/2025?
No. Organic Law 1/2025 keeps the maximum investigation deadlines of Art. 324 LECrim: 12 ordinary months, extendable depending on the complexity of the case. What changes is the processing, which becomes fully digital with automated calculation of deadlines.
Is criminal mediation available under the new law?
Criminal mediation remains voluntary and its impact is limited, but the law expressly recognises its effects on the mitigating factor of repair of the harm under Art. 21.5 CP and on suspension or substitution of the penalty. It is excluded in gender violence, terrorism and sexual offences against minors.
What does the digital justice introduced by Organic Law 1/2025 mean for the person under investigation?
Processing, notifications and filings become electronic, and videoconferencing is prioritised for the statements of witnesses, experts and authorities. This requires the lawyer to monitor the electronic file daily, because any relevant ruling triggers a notification with a strict deadline to appeal.
