In the field of serving custodial sentences there are two figures that are frequently confused, even among those who know criminal law: the accumulation of sentences and the consolidation of convictions. Both affect the time a convicted person must spend in prison when they have several convictions, and both seek to avoid a disproportionate term, but they are legally distinct. Confusing them can cause important benefits to be lost.
The accumulation of sentences is the mechanism in Article 76 of the Criminal Code that limits the maximum time served when a person has been convicted in different proceedings. It consists of applying to the set of convictions a maximum limit, three times the most serious sentence or the absolute caps of twenty years or more, which determines the actual time in prison. It operates before or at the start of service, although it can be requested afterwards. Its fundamental requirement is chronological: the offences must have been committed before service of any of the convictions began.
The consolidation of convictions is a different figure, developed also in the Penitentiary Regulations and in the practice of the prison supervision judge. It consists of unifying all the convictions that the inmate is serving or has pending into a single calculation, with a single release date. Its natural moment is when the convicted person is already in prison, and it is carried out by the penitentiary facility and the prison supervision judge, not the sentencing court.
The key differences are several. The timing: accumulation is decided before the sentencing court; consolidation operates already within the prison system. The competent body: accumulation falls to the court that issued the most serious sentence; consolidation, to the penitentiary facility and the prison supervision judge. The temporal criterion: accumulation requires that the offences predate the start of service; consolidation has no temporal criterion of its own, but applies the one established by the accumulation.
The essential thing is to understand that they are not mutually exclusive figures, but complementary and sequential ones: accumulation establishes the maximum ceiling for time served by means of a judicial ruling, and consolidation integrates that ceiling into the inmate’s sentence calculation. An accumulation without correct consolidation is ineffective, because the inmate will not benefit from the limit if the calculation does not reflect it. And consolidation cannot go beyond what the accumulation has recognised.
The confusion arises in typical situations: the inmate with multiple convictions who never requested accumulation and to whom everything has been added; the calculation that does not reflect the result of an accumulation already granted; or the partial accumulation, in which some convictions are left out for not meeting the temporal requirement.
The correct handling of both figures is one of the areas where the lawyer’s specialisation matters most, because it enters the law of sentence enforcement, which many do not master. There are convicted persons who serve more time than they should simply because no one has properly requested accumulation or because the calculation is wrong. That is why, in case of any doubt about whether the calculation is correct, a review with a specialised lawyer is advisable: the result can bring the release date forward in a very concrete way.
