An addiction, a mental illness or a violent or sexual offence requiring treatment changes the whole prison sentence. Whether a person receives the necessary treatment decides not only the quality of life inside, but often the timing of release. This post shows which treatment paths Austrian law opens during imprisonment, from a health-related measure instead of punishment, through withdrawal treatment in detention, to the social-therapeutic engagement with the offence.

The legal foundations lie in the Prison Enforcement Act (StVG), the Narcotic Substances Act (SMG) and the Criminal Code (StGB). They interlock: what is achieved in treatment during enforcement bears directly on relaxations of detention and on conditional release. From a legal perspective it pays to treat the therapy not as a side issue but as a central lever of the entire course of enforcement.

01 Question 1

What does treatment during enforcement concern?

Addiction, mental illness and violent or sexual offences requiring treatment follow different paths during imprisonment. Choose the constellation that comes closest to your situation, you will receive an assessment with concrete first steps.

All paths at a glance

Overview of all answers.

01

Before commencing the sentence, examine deferral under Section 39 SMG, a health-related measure instead of detention.

For a custodial sentence of no more than three years for an offence committed in connection with addiction to narcotic substances, enforcement can be deferred under Section 39 SMG (Narcotic Substances Act) for up to two years if the convicted person agrees to complete a health-related measure, that is, outpatient or inpatient treatment, psychotherapy or another medically supervised withdrawal. This constellation is known as therapy instead of punishment (Therapie statt Strafe).

What to do now: First, contact a suitable treatment facility and obtain confirmation of admission or treatment. Second, file the application for deferral in good time before commencing the sentence. Third, document the course of treatment, because if the treatment is completed successfully, Section 40 SMG opens the door to a subsequent conditional remission of the sentence. If the treatment is broken off or not started, the deferral is revoked and the sentence is enforced.

02

During detention, apply for withdrawal treatment under Section 68a StVG, places are limited.

If the sentence is already being served, most prisons (Justizanstalten) offer withdrawal treatment. Section 68a StVG provides for the treatment of addicted prisoners within the institution, from outpatient counselling to dedicated therapy units. Participation is voluntary, but often decisive for later conditional release, because Section 46 para 4 StGB expressly names voluntary treatment begun during enforcement as a circumstance that improves the prognosis.

What to do now: First, apply for admission to a therapy programme early, because places are limited. Second, anchor the request in the enforcement plan (Vollzugsplan), so that therapy, work and relaxation stages are coordinated. Third, have the course of treatment confirmed in writing, this confirmation is later one of the strongest arguments in the conditional release proceedings.

03

Enforce medical treatment under Sections 66, 68 StVG, where needed examine transfer or fitness for detention.

Even in detention there is a right to healthcare meeting the general standard. Section 66 StVG enshrines healthcare as a principle, Section 68 StVG requires medical, where necessary specialist, treatment and care. If the prison outpatient unit is insufficient, treatment in a hospital ward, in the prison hospital (Justizkrankenhaus) or, in exceptional cases, in an external specialist clinic must be ensured.

What to do now: First, bring existing findings and ongoing therapies into the institution early, most reliably through correspondence via your lawyer, so that continuity of treatment is preserved. Second, where care is inadequate, consider the enforcement complaint (Vollzugsbeschwerde) under Section 120 StVG. Third, where the illness is severe and cannot be treated during enforcement, examine fitness for detention, a deferral or interruption of the sentence may be considered. Separate from imprisonment is the preventive measure (Maßnahmenvollzug) under Section 21 StGB, which concerns only offenders lacking criminal responsibility or who are dangerous.

04

Begin social-therapeutic treatment early, it supports relaxations and conditional release.

With violent and sexual offences, the enforcement court (Vollzugsgericht) regularly expects, for relaxations and for conditional release, proof of a serious therapeutic engagement with the offence. Prisons keep social-therapeutic programmes available for this, partly in dedicated units. Treatment against the person's will is excluded, an instruction to undergo medical treatment under Section 51 para 3 StGB may only be issued with consent and may not prescribe any intervention involving bodily harm.

What to do now: First, apply early for admission to a suitable treatment programme. Second, document progress, because Section 46 para 4 StGB recognises treatment begun during enforcement as relevant to the prognosis. Third, coordinate the therapy with the enforcement plan and the intended relaxation perspective, without this proof, release at the halfway point is practically excluded in such cases.

What carries treatment during enforcement in law

Imprisonment is an interference with personal liberty, but it does not suspend the right to healthcare. Section 66 StVG enshrines healthcare as a principle of prison enforcement: the care of prisoners should meet the general standard that applies outside the institution. This principle of equivalence is the yardstick against which every treatment decision must be measured.

If a prisoner falls ill, is injured or has an accident, the prison doctor must be called in under Section 68 StVG. The doctor must ensure the necessary medical, where required specialist, treatment and care. If care within the institution is insufficient, treatment in a hospital ward, in the prison hospital or, in exceptional cases, in an external clinic comes into consideration.

Continuity is decisive. Anyone entering detention with an existing diagnosis or an ongoing therapy should bring the findings in early, most reliably through correspondence via a lawyer, which is not subject to mail screening. Documents submitted directly do not always arrive in practice. Seamless documentation prevents interruptions to treatment and is at the same time the foundation for any later release perspective.

Addiction: deferral under Section 39 SMG and withdrawal under Section 68a StVG

With addiction, the law knows two separate paths, depending on whether the sentence is still ahead or is already being served. Before commencing the sentence stands the deferral under Section 39 SMG. For a custodial sentence of no more than three years for an offence connected with addiction to narcotic substances, enforcement can be deferred for up to two years if the convicted person agrees to a health-related measure. This constellation, known as therapy instead of punishment, can entirely replace enforcement in the institution.

If the treatment is completed successfully, Section 40 SMG opens the door to a subsequent conditional remission of the sentence. If the measure is not started or is broken off, the deferral is revoked and the sentence is enforced. During the deferral the court may request confirmations of the start and progress of treatment.

If the sentence is already being served, Section 68a StVG applies. It provides for the withdrawal treatment of addicted prisoners within the institution, from outpatient counselling to specialised therapy units. Participation is voluntary. Anyone who wishes to complete it should apply early, because places are limited. The benefit reaches beyond the institution, because Section 46 para 4 StGB expressly names voluntary treatment begun during enforcement as a circumstance that improves the prognosis for conditional release.

Mental illness during enforcement

With mental illness there is a right to adequate treatment by the same yardstick as for physical conditions. The first point of contact is the prison outpatient unit. If it is insufficient, specialised care must be ensured, for example through transfer to a hospital ward or to an institution with a psychiatric focus.

If necessary treatment is refused or delayed, the enforcement complaint under Section 120 StVG is the way to enforce it. With a severe illness that cannot be adequately treated during enforcement, fitness for detention must also be examined. A deferral or interruption of the sentence on health grounds may come into consideration.

The distinction from the preventive measure is important. Placement in an institution for mentally abnormal offenders under Section 21 StGB concerns offenders lacking criminal responsibility or who are especially dangerous and is not a form of imprisonment. A mental illness during imprisonment does not automatically lead into the preventive measure, it is to be treated within prison enforcement.

Which path for which problem

Treatment paths at a glance

Which legal path applies depends on the problem and the stage of proceedings. The overview orders the most important constellations, in the individual case a precise examination is required.

Treatment paths during imprisonment by problem, legal basis and required proof
Problem Legal basis and path What must be proven
Addiction before commencement Addiction, sentence up to three years, not yet commenced Deferral of enforcement under Section 39 SMG, therapy instead of punishment, then Section 40 SMG Confirmation of admission by the facility, declaration of willingness to undergo treatment
Addiction in detention Addiction, sentence already being served Withdrawal treatment within the institution under Section 68a StVG Application for a therapy place, anchoring in the enforcement plan, confirmation of progress
Mental health Mental illness during detention Medical treatment under Sections 66, 68 StVG, where needed transfer or fitness for detention Prior findings, specialist opinion, where applicable complaint under Section 120 StVG
Violent and sexual offences Treatment need with a relevant offence Social-therapeutic treatment, relevant to the prognosis under Section 46 para 4 StGB Admission to the programme, documented therapy progress

An instruction to undergo medical treatment may, under Section 51 para 3 StGB, only be issued with consent and may not prescribe any intervention involving bodily harm. Treatment during enforcement is voluntary, its benefit for relaxations and release nonetheless makes it the central lever.

Violent and sexual offences: treatment as the key to release

With violent and sexual offences, the therapeutic engagement with the offence is not a voluntary extra but in practice the precondition for relaxations of detention and for conditional release. For relevant offences the enforcement court regularly expects proof of serious treatment begun during enforcement and capable of bearing weight. Without this proof, release at the halfway point in particular is practically excluded.

Prisons keep social-therapeutic programmes available for this, partly in dedicated units with specialised staff. Treatment against the person's will is excluded. If, within a conditional release, an instruction to undergo medical treatment under Section 51 para 3 StGB is issued, it requires the consent of the person concerned and may not order any intervention involving bodily harm.

The practical advice is to begin treatment early and to document its course. Section 46 para 4 StGB expressly recognises voluntary treatment begun during enforcement as a circumstance that can carry a changed prognosis. Anyone who coordinates therapy, enforcement plan and relaxation perspective builds, over months, the basis for an earlier release.

Frequently asked

What is often asked about treatment during imprisonment.

Do I have a right to medical treatment in detention? +

Yes. Section 66 StVG enshrines healthcare as a principle of prison enforcement, the care should meet the general standard outside the institution. In the event of illness, accident or injury, the prison doctor must be called in under Section 68 StVG, who must ensure the necessary medical, where required specialist, treatment and care. If the prison outpatient unit is insufficient, treatment in a hospital ward, in the prison hospital or in an external clinic is possible.

Can addiction therapy replace imprisonment? +

For a custodial sentence of no more than three years for an offence connected with addiction to narcotic substances, enforcement can be deferred under Section 39 SMG for up to two years if the convicted person agrees to a health-related measure. If the treatment is completed successfully, a subsequent conditional remission of the sentence is possible under Section 40 SMG. If the treatment is not started or is broken off, the deferral is revoked and the sentence is enforced.

What addiction treatment is available during the ongoing sentence? +

Section 68a StVG provides for the withdrawal treatment of addicted prisoners within the institution, from outpatient counselling to specialised therapy units. Participation is voluntary, places are limited, so an early application is important. Treatment begun during enforcement is, under Section 46 para 4 StGB, a circumstance that improves the prognosis for conditional release.

What happens with a mental illness in detention? +

There is a right to adequate treatment. If the prison outpatient unit is insufficient, specialised care must be ensured, for example through transfer. If treatment is refused, the enforcement complaint under Section 120 StVG is the way. For a severe illness that cannot be treated during enforcement, fitness for detention must be examined, a deferral or interruption may come into consideration. The preventive measure under Section 21 StGB is separate from this, it concerns offenders lacking criminal responsibility or who are dangerous and is not imprisonment.

Can I be forced into therapy? +

No. Treatment during enforcement is voluntary. An instruction to undergo medical treatment within a conditional release may, under Section 51 para 3 StGB, only be issued with the consent of the person concerned and may not prescribe any intervention involving bodily harm. In practice, treatment is nonetheless often the decisive step, because it co-determines relaxations and the timing of release.

Why is therapy so important for conditional release? +

Because, with addiction, violent and sexual offences, the enforcement court regularly expects proof of a serious engagement with the offence. Section 46 para 4 StGB expressly names voluntary treatment begun during enforcement as a circumstance relevant to the prognosis. Without this proof, release at the halfway point in particular is practically excluded in such cases. Anyone who begins early and documents the course builds the basis for an earlier release.
