The suspension of sentence execution provided for by Article 90 of Presidential Decree 309/1990 can prevent the immediate serving of a custodial sentence in a very specific situation: the conviction must be linked to a state of drug addiction, and a therapeutic and socio-rehabilitative program must have been successfully completed. Therefore, it is neither an automatic benefit nor a measure designed for individuals who still need to begin a rehabilitation path.
Understanding whether this path is viable requires a careful distinction between the sentence to be served, the relationship between the offence and the addiction, the content of the medical certification, and the effects arising from the fact that this benefit can be granted only once. I will explain the essential conditions, what happens after the suspension, and why, in certain cases, it may be more pertinent to evaluate a different legal institution.
What is the suspension of execution under Article 90
Article 90 suspends the execution of the sentence, it does not immediately erase the conviction. The Surveillance Court may suspend for five years the execution of a custodial sentence imposed for offences committed in relation to a state of drug addiction. This legal institution therefore concerns the phase following a final judgment: the issue is no longer establishing whether the offence was committed, but defining how the sentence must be executed.
The rationale of the provision is linked to a recovery already achieved. The suspension presupposes that the individual has successfully undergone a therapeutic and socio-rehabilitative program at a public health facility or an authorized private structure. The Constitutional Court recalled this requirement, together with the five-year duration of the suspension and the applicable sentence limits, when describing the system established by the consolidated text on narcotics.

It must not be confused with the conditional suspension of a sentence. The latter is a benefit that the judge may grant with the judgment of conviction under different rules. Article 90, instead, operates before the surveillance judiciary and concerns a person who has already been definitively convicted, with a therapeutic path successfully concluded and documented in the ways required by law.
Nor does it coincide with therapeutic probation under Article 94. Probation in special cases is intended for those who have an ongoing recovery program underway or intend to start one, and it entails serving the sentence outside prison with specific obligations and controls. Conversely, the suspension under Article 90 concerns a program that has already ended with a favorable outcome. This distinction alters the solution to be taken into consideration.
The requirements: sentence, addiction, and completed program
The sentence to be served cannot exceed six years. The limit concerns the custodial sentence, including any remaining portion and even if accompanied by a pecuniary penalty. If the enforcement order includes an offence listed under Article 4-bis of the penitentiary administration act, the limit drops to four years. Thus, looking solely at the sentence indicated in a single judgment is not enough: it is necessary to understand which sentence must be concretely executed and which offences comprise the enforcement title.
The offence must be linked to the state of drug addiction. Addiction is not a separate element from the conviction. A relationship must emerge between the condition of drug addiction and the offences for which the sentence was imposed. The Court of Cassation reiterated in 2026 that this link must actually exist and that a generic declaration regarding addiction is insufficient. Court of Cassation Review, January 2026, judgment no. 631, filed on 8 January 2026
The program must be successfully concluded before the decision. A program still underway may be important for other measures, but it does not alone satisfy the prerequisite of Article 90. The Surveillance Court must be able to ascertain the results of the therapeutic and socio-rehabilitative pathway through the final report provided for by Article 123 of the consolidated text.
The medical certification is a decisive part of the application. Under penalty of inadmissibility, the request must be accompanied by a certification issued by the public addiction service or by a private facility authorized for diagnosis. The document must allow for the reconstruction of how habitual substance use was ascertained, which program was carried out, where it took place, under what modalities, and with what results. Documentation that merely attests to the intake, without making the outcome of the program recognizable, may fail to meet the purpose required by Article 90.
Certain new offences must not intervene between the start of the program and the decision. The suspension cannot be granted if, during that period, the convicted person has committed another intentional crime punishable by imprisonment. This is a limit distinct from the one operating after the concession: prior to the decision, it prevents the benefit; during the subsequent five-year period, it can lead to revocation and the effects provided for by Article 93.
Why it is referred to as a benefit granted only once
The suspension under Article 90 cannot be granted more than once. This is the correct meaning of the expression "unique opportunity": the limit concerns the specific benefit regulated by Article 90 of Presidential Decree 309/1990. It does not mean that every application submitted exhausts the benefit, nor that a person can never access other legal institutions provided by law when the conditions independently occur.
A rejection does not equate to the granting of the benefit. If the sentence limit, the connection between the offence and the addiction, the positive outcome of the program, or a suitable certification is missing, the application may be declared inadmissible or dismissed. This does not transform a negative decision into a suspension already granted. However, it remains essential to understand precisely the reason behind the measure, because not every deficiency can be resolved in the same way.
The rule of a single concession requires avoiding the overlap of different legal institutions. Requesting Article 90 while the therapeutic pathway is still open may mean directing the request toward a benefit that is inconsistent with the facts. If the person must continue or undertake therapy, the discipline of therapeutic probation may be the one to examine; if instead the path has been successfully completed, Article 90 may become relevant.
This limit does not eliminate the evaluation power of the Court. Even upon the first request, the Surveillance Court must verify all prerequisites. The provision uses the verb "may": the presence of a certification and a sentence within the threshold does not replace judicial assessment regarding the connection to the addiction and the actual outcome of the program.
What happens after the suspension
The suspension lasts five years. During this period, the execution of the custodial sentence remains on hold. The effect is not the immediate extinction of the sentence: extinction can only materialize if, within the subsequent five years, the convicted person does not commit an intentional crime punishable by imprisonment. The discipline of Article 93 links the extinction of penalties and other criminal effects of the conviction to this condition.
A new intentional crime can compromise the result. If an intentional crime punishable by imprisonment is committed within the five-year period, the suspension is revoked by operation of law. Therefore, it is incorrect to consider the suspension period as a phase devoid of consequences: the behavior subsequent to the measure is an integral part of the mechanism established by the law.
The civil consequences of the offence remain unaffected. The suspension renders accessory penalties, security measures, and other criminal effects of the conviction inapplicable, with the exception of confiscation, but it does not extend to civil obligations arising from the offence. Compensation owed to the injured party, for example, does not cease merely because the suspension of criminal execution is granted.
The pecuniary penalty requires a further prerequisite. The Surveillance Court may also suspend an uncollected pecuniary penalty only if the interested party is in straitened financial conditions. Consequently, the suspension of a pecuniary penalty is not an automatic consequence of the suspension of a custodial sentence.
Application, competent authority, and useful documents
The decision falls under the jurisdiction of the Surveillance Court. The request is part of the execution phase of the conviction and must be accompanied by the required medical documentation. When a person is free and receives an execution order accompanied by a suspension decree, the notice indicates the deadline within which to file the request for an alternative measure or for the suspension provided by the consolidated text; under the ordinary procedure of Article 656 of the Code of Criminal Procedure, the indicated deadline is thirty days.
Promptness serves to avoid losing the suspension ordered by the public prosecutor. If the motion is not filed within the indicated deadline, is inadmissible, or is rejected, the execution of the sentence may resume. The guidelines issued by the Ministry of Justice distinguish the suspension under Article 90 from therapeutic probation and recall both the six-year limit and the necessity of medical certification attached to the application.

The final report must explain the pathway, not merely assert its existence. The verification of the state of drug addiction matters, but the description of the program carried out and the results achieved matters just as much. The Court of Cassation has specified that, for Article 90, the report provided for by Article 123 must be acquired, drafted according to the procedures established by the provision. This clarifies why overly concise certifications may prove insufficient.
The sentence to be served must be calculated on the effective enforcement title. In the presence of multiple convictions, sentence accumulations, or remaining sentences, the threshold of six or four years cannot be derived from an isolated reading of the most recent judgment. Furthermore, the potential presence of an offence under Article 4-bis of the penitentiary administration act may affect the applicable limit. Before choosing the application, it is useful to have the execution order, the accumulation decree if one exists, and the relevant judgments.
When Article 4 may be the alternative to consider
Those who still need to undergo therapy do not normally fall within the scheme of Article 90. Probation in special cases provided for by Article 94 of Presidential Decree 309/1990 is addressed to drug-addicted or alcohol-addicted persons who have an ongoing therapeutic program or intend to undergo one. Here, therapy is not a finished fact: it is the content of the pathway that accompanies the execution of the sentence.
The main difference lies between suspending the sentence and executing it in an alternative form. Under Article 90, if the requirements are ascertained, execution is suspended for five years following a previously concluded positive program. Under Article 94, the sentence is instead executed through an alternative measure, with prescriptions linked to the recovery program. This is not a formal distinction: it changes the type of documentation needed and the facts the judge must evaluate.
Alcohol addiction requires particular attention when choosing the institution. The suspension under Article 90 is designed for drug-addicted persons; the therapeutic probation of Article 94 also encompasses alcohol addiction. Therefore, it is incorrect to automatically transfer the requirements of one to the other. The clinical definition of the condition and the timing of the therapeutic program guide the application more than the mere duration of the sentence.
It is inadvisable to wait for the conclusion of the program solely to attempt Article 90. If the sentence must be executed and the recovery pathway is still necessary, the measures available at that moment must be considered, without taking for granted that a future institution will be more advantageous. The useful benefit is the one corresponding to the real prerequisites, the execution phase, and the documentation concretely available.
Facts that truly change the answer
The completion date of the program can be decisive. A program started years prior, but interrupted or not successfully concluded, does not carry the same meaning as a pathway terminated with a favorable final report. Even a very serious program does not allow the use of Article 90 if the requirement of a positive outcome demanded by the rule is missing.
The connection between addiction and the offence is not presumed. The period in which the facts were committed, the personal condition at that time, and what emerges from the case files and medical documentation may become relevant. If the offence is entirely unrelated to the addiction, the mere existence of a therapeutic pathway is insufficient; if instead the link is documentable, that fact enters directly into the evaluation required by Article 90.
The initial choice must be consistent with the current status. To prepare the first consultation, the execution order, judgments or the accumulation decree, the certification from the addiction service, the final report on the program, and documents showing any prior concessions of Article 90 are normally useful. These acts serve to correctly position the application, not to create non-existent requirements.
Frequently asked questions
Can I request Article 90 if my therapeutic program is still underway?
No, an ongoing program is not enough for Article 90. The suspension requires the Court to ascertain the positive outcome of a program that has already concluded. If you need to continue or begin recovery, it may be more pertinent to consider the therapeutic probation provided by Article 94, which has different prerequisites and consequences.
Does the suspension under Article 90 also apply to alcohol addiction?
Article 90 concerns drug addiction. It should not be automatically extended to alcohol addiction. For an alcohol-addicted person, probation in special cases under Article 94 may instead become relevant, as it encompasses both conditions. The medical certification must precisely identify the relevant condition.
If the sentence is exactly six years, can I obtain the suspension?
The ordinary limit is a custodial sentence, including any remaining portion, not exceeding six years. However, if the enforcement title includes an offence indicated by Article 4-bis of the penitentiary administration act, the applicable limit is four years. Furthermore, the connection between the offence and drug addiction as well as the positive outcome of the program must be present.
Does a rejected application prevent me from resubmitting it?
The prohibition concerns a suspension already granted, not a request that was simply rejected. However, one must understand why the application was not accepted. If a substantive requirement was missing, such as the connection between the offence and the addiction, adding irrelevant documents is not enough; if a necessary attachment was missing, the problem may be different.
Does the suspension also eliminate compensation for damages?
No, the civil obligations arising from the offence remain unaffected. The suspension may impact accessory penalties, security measures, and the criminal effects of the conviction within legal limits, but it does not automatically extinguish the debt for damages owed to the injured party or other civil obligations.
Essential references and final guidance
The norm to consider is Article 90 of Presidential Decree no. 309 of October 9, 1990, together with Articles 91, 93, and 123. The point to clarify is not only whether an addiction exists, but whether the program has been successfully completed, whether the offences are linked to that condition, what sentence must be executed, and whether the benefit has already been granted in the past. The Constitutional Court and the Court of Cassation cited in this guide help read these requirements as a whole.
A well-targeted request starts with the correct distinction. If the program is completed and all prerequisites are documentable, Article 90 may be the norm to examine. If the program still needs to be carried out or continued, suspension does not replace the tools provided for the therapeutic execution of the sentence.
