Sentence Merger and Accumulation: the Art. 76 CP Cap

A person who has accumulated several convictions does not, fortunately, serve the plain arithmetical sum of all of them. The Criminal Code (CP) sets a maximum cap on the effective term served, and the Criminal Procedure Act (LECrim) provides the route to apply it: the legal accumulation of penalties. As criminal lawyers in sentence enforcement and prison law, we explain how Art. 76 CP works, how the cap is calculated and why pursuing the most favourable accumulation can entirely change the outlook for someone deprived of liberty.

Merger and Accumulation: Two Different Things

It helps to clear up a common confusion. The merger of sentences (refundición) is the administrative operation by which the prison unifies several penalties into a single enforcement file, for the purposes of calculation and benefits. Legal accumulation is the judicial decision that, under Art. 76 CP and Art. 988 LECrim, fixes the maximum effective term and declares extinguished any penalties exceeding that cap.

It is the judicial accumulation that produces the most significant effect: placing a ceiling on the sentence. That is why it is the part the defence must work on most carefully.

The Maximum Cap of Art. 76 CP

Art. 76.1 CP provides that the maximum effective term served may not exceed three times the period of the most serious penalty imposed, the remaining penalties being declared extinguished once those already imposed cover that maximum. Over that rule operate certain absolute caps:

• 20 years: the general limit.
• 25 years: where the person has been convicted of two or more offences and one of them carries a prison penalty of up to 20 years.
• 30 years: where one of the offences carries a prison penalty of more than 20 years.
• 40 years: where at least two offences carry a penalty of more than 20 years, or in qualified cases of organisations and terrorism offences with one of them above 20 years.

Art. 76.1 CP also contains a specific rule for cases where one of the offences carries a reviewable permanent imprisonment penalty, referring to Arts. 78 bis and 92 CP. And Art. 76.2 CP states that the limit applies even where the penalties were imposed in separate proceedings, provided the offences were committed before the date on which the first of those subject to accumulation were tried. That temporal connection is the key to the system.

How the Cap is Calculated

The calculation has two steps. First, the most serious penalty imposed is identified and multiplied by three (the "triple of the greatest"). Then that result is compared with the relevant absolute cap from the table above, and the lower of the two applies. The arithmetical sum of all the penalties only matters to confirm that the limit is in fact exceeded; from there, everything beyond it is declared extinguished.

The actual calculation always depends on the exact penalties, the dates of the offences and the dates of the judgments, so it must be checked case by case.

Accumulation under Art. 988 LECrim

Art. 988 LECrim is the procedural route that gives effect to the Art. 76 CP limit. Where a person has been convicted in separate proceedings for facts that could have been the subject of a single one (under the connection rules of Art. 17 LECrim), the body that delivered the last judgment —of its own motion, at the request of the public prosecutor or of the convicted person— fixes the enforcement limit of the penalties imposed.

The procedure is formal: the criminal record sheet from the Central Register and certified copies of the convictions are obtained, the public prosecutor is heard where not the applicant, and an order is issued listing all the penalties and setting the maximum term. That order may be challenged by cassation appeal for breach of law, which has allowed the Supreme Court to build a settled body of doctrine on the matter.

The decisive requirement is the temporal connection: convictions for facts committed before the first of those being accumulated were tried may be accumulated, even if pursued in separate cases. The offences need not be of the same type or materially related; it is enough that they could have been tried together.

Effects on Leave, Open Prison and Parole

The cap resulting from the accumulation does not only shorten the total time: it becomes the basis for calculating prison benefits. The time limits for leave permits, classification in third grade (open prison) and ordinary parole under Art. 90 CP (serving three quarters of the sentence) or early parole under Art. 91 CP are all computed on that maximum penalty. Reducing the computation penalty from 40 to 20 years brings forward, in practice, the entire progression calendar.

It is worth bearing in mind Art. 78 CP: where, as a result of the limit, the term to be served turns out to be less than half the total sum of the penalties imposed, the court may order that prison benefits, leave, third grade and the computation for parole refer to the full set of penalties rather than the reduced limit. Anticipating this scenario is part of a well-planned strategy.

The Defence: Pursuing the Most Favourable Accumulation

Accumulation often allows for more than one possible combination of the convictions, depending on which judgment is taken as the temporal reference. The defence's task is to examine every final judgment, the dates of the offences and of the trials, and to propose to the court the grouping that yields the most favourable enforcement limit for the person.

• Full review of the criminal record sheet and of each final judgment.
• Analysis of the temporal connection to determine which penalties are accumulable with one another.
• Proposal of the optimal combination and, where appropriate, a cassation appeal against an unfavourable order.
• Request for review where new convictions arise or where the accumulation already carried out proves not to have been the most favourable.

Detail matters: an error in the date of finality taken as the reference, or the omission of an accumulable judgment, can translate into extra years of imprisonment. That is why the study of the accumulation is best entrusted to those who handle sentence enforcement and the prison phase on a daily basis, and the resulting order should be reviewed before it becomes final.

We do not promise a specific result —it depends on the penalties and the dates of each file— but we work to ensure that the limit fixed is the one that best accords with the law and is most favourable to our client, exhausting, where necessary, the cassation appeal provided for in Art. 988 LECrim.
