With the final judgment a new chapter begins that follows its own rules. While pre-trial detention secures the ongoing proceedings, imprisonment is about the execution of a custodial sentence imposed by a final judgment. For convicted persons and their relatives, very concrete questions now arise: when and where will the sentence be served, can it be deferred or served at home, what rights apply in the facility, and which routes lead to liberty sooner? This article walks you through the entire course of imprisonment in Austria, from the summons to begin the sentence through the execution plan and the relaxations to conditional release.

Imprisonment in Austria is governed by the Sentence Enforcement Act (Strafvollzugsgesetz, StVG), the requirements of conditional release by the Criminal Code (Strafgesetzbuch, StGB). It is an interference with personal liberty, but it is not the suspension of all other rights: health, contact, work and the right to complain remain protected and enforceable. This article is the opening piece of a series on imprisonment; the topic pages on the individual building blocks, start of the sentence and deferral, relaxations of execution, transfer, rights during execution, electronically monitored house arrest and conditional release, are linked at the end. For an in-depth look at a particular stage, go there directly; this overview places the building blocks in the procedural course.

Where do you stand in execution? What needs to be done now?

Where do you stand right now, and which lever fits now?

Imprisonment follows clear stages: the summons to begin the sentence after the judgment becomes final, committal and classification, the execution plan, staged relaxations and finally conditional release after half or after two thirds. Which measure applies at which stage depends on the state of execution. Choose the constellation that matches your situation, you receive an assessment with concrete first steps.

01 Question 1

Where do you stand in the execution of the sentence right now?

The right lever depends on the stage of execution. An upcoming start of the sentence after the judgment becomes final, ongoing execution with an open sentence execution plan, an approaching half-way or two-thirds mark, or a concrete conflict in the facility, each phase calls for a different response. Choose the constellation that matches your situation; you receive a short assessment with concrete next steps.

All paths at a glance

Overview of all answers.

01

Start of the sentence is imminent, now examine a deferral under section 6 StVG and electronically monitored house arrest.

Once the judgment is final, the public prosecutor takes over enforcement. The competent prison facility summons the convicted person in writing to begin the sentence within a set period, as a rule within four weeks of service. Anyone who does not comply risks an order to be brought in by force. Yet this very period is also the window in which a deferral of the sentence under section 6 of the Sentence Enforcement Act (StVG) can be applied for, for example on health, family or economic grounds.

Concrete steps now: first, examine whether the remaining sentence qualifies for electronically monitored house arrest. The threshold is a remaining duration of 24 months; for the catalogue offences under section 156c paragraph 1 number 1 StVG it stays at twelve months. Second, support the deferral grounds under section 6 StVG with evidence, medical reports, proof of the family care situation, documents on the professional or economic position. Third, raise the question of the choice of facility early, because proximity to home co-determines later family contact and thus the prospects for relaxations and release.

02

Execution is ongoing, actively shape the execution plan under section 135 StVG and stage the relaxations.

For longer sentences, in practice from about twelve months, the facility draws up a sentence execution plan under section 135 StVG. It sets out how the sentence will run: work or training, therapy where appropriate, levels of relaxation, possible transfers, preparation for release. The execution plan is not a one-sided document of the facility; the imprisoned person has a right to be heard and can bring in their own concerns. Anyone who brings in concrete wishes early, often already in the first execution interview, shapes the course of the months or years ahead.

Concrete steps now: first, record your own goals for the execution plan in writing, a work place in the facility, an educational measure, a planned therapy. Second, understand relaxations of execution under sections 99 et seq. StVG as a staged build-up, accompanied leave, unaccompanied leave, outside employment, day release, and prepare each level with evidence. Third, if the assigned facility is poorly located, examine a transfer under sections 134 et seq. StVG early, because proximity to home, the therapy offer and the type of facility shape the prospects for relaxations and release.

03

Prepare conditional release under sections 46, 47 StGB, support the social prognosis with documented structures.

Conditional release under sections 46 and 47 of the Criminal Code (StGB) is the most common way out of imprisonment, not the exception. The great majority of cases are decided not by the full end of the sentence but by a conditional release, usually after serving two thirds, in particularly favourable constellations already after half. The decision is taken by the execution court (Vollzugsgericht). The central question is whether it can be assumed that the convicted person will not commit further offences in future.

Concrete steps now: first, support the social prognosis with documented structures, a concrete and secured address, a written employer commitment or a training place, and for relevant prior offences proof of a therapy begun and sustained during execution. Second, build contact with the probation service (NEUSTART) early, its statement carries the rehabilitation perspective. Third, if conditional release is rejected, use the appeal to the Higher Regional Court within fourteen days of service and clarify in parallel what can concretely be improved before the next application.

Execution complaint under section 121 StVG within two weeks, alongside a petition to the Ombudsman Board.

Even in custody the imprisoned person remains a holder of rights. Against decisions of the facility management, the execution complaint under section 121 StVG to the execution chamber (Vollzugskammer) of the competent Regional Court is open. The deadline is two weeks from service or oral pronouncement. Open to complaint are, for example, the refusal of relaxations, disciplinary decisions, transfers against the will of the person, and restrictions of visit, letter or telephone rights, as well as decisions on work or yard time.

Concrete steps now: first, observe the two-week deadline exactly and argue the complaint not in general terms but with concrete legal reasoning, which provision was disregarded, which facts were overlooked, which other decision would have been required. Second, use the petition right to the Ombudsman Board (Volksanwaltschaft) in parallel, which is not tied to the complaint deadline and is effective precisely where a recurring practice rather than a single decision is at stake. Third, document the incident, date, persons involved, course of events, because a documented chronology supports the complaint far more strongly than later recollection.

What imprisonment is and how it differs from pre-trial detention

Imprisonment is the execution of a custodial sentence imposed by a final judgment. It is fundamentally different from pre-trial detention. Pre-trial detention is imposed on a person against whom no final guilty verdict has yet been handed down, and who is presumed innocent until conviction; it secures the ongoing criminal proceedings and is governed by sections 173 to 179 of the Code of Criminal Procedure (StPO). Imprisonment, by contrast, presupposes a final judgment and executes the sentence imposed; it is governed by the Sentence Enforcement Act. An overview of pre-trial detention can be found in the separate article on pre-trial detention.

This distinction has tangible consequences. In pre-trial detention everything turns on the suspicion, the grounds for detention and the question whether a less restrictive measure can replace detention. In imprisonment the question of guilt is no longer at issue; what is now central is the shaping of execution and the preparation of release. From a lawyer’s perspective the emphasis therefore shifts from defending against the charge towards actively shaping execution: the execution plan, relaxations, transfer, therapy and the early build-up of a sustainable release perspective.

The crediting of time also matters: pre-trial detention served before the judgment is credited against the custodial sentence under section 38 StGB. Anyone who was already in pre-trial detention has therefore served part of the sentence before imprisonment in the narrow sense begins. This has a direct effect on calculating the half-way point, the two-thirds mark and the remaining duration for electronically monitored house arrest.

From the final judgment to the start of the sentence

As soon as the judgment is final, the public prosecutor acts as the enforcement authority. The competent prison facility issues a summons to begin the sentence to the convicted person; it names the date, the facility and the sentence to be served, and as a rule must be complied with within four weeks of service. Anyone who does not comply risks an order to be brought in by force and a forced committal to the facility. This period is therefore not a mere formality but the decisive window in which there is still room to act.

Within this window three questions must be clarified at once. First: does electronically monitored house arrest come into consideration instead of custody in the facility? It is possible under sections 156b et seq. StVG up to a remaining duration of 24 months; for the serious offences listed in section 156c paragraph 1 number 1 StVG it stays at twelve months. Second: are there grounds for a deferral under section 6 StVG? The statute recognises health, family and economic grounds for deferral, each with its own burden of reasoning. Third: which facility is organisationally favourable, for example because of proximity to home, a work place or family ties?

To be distinguished from the deferral is the later interruption of the sentence, that is, the temporary suspension of an execution already under way for a concrete, definable reason. Both instruments buy time but do not remit the sentence. Clearly distinct again is a pardon by the Federal President, an act of grace without any legal entitlement that is attainable only in exceptional cases. Anyone aiming at a shortening of the sentence should not confuse these routes; the calculable regular route is conditional release.

Classification and the execution plan

After committal comes classification: the enforcement authority assigns the convicted person, according to the length of the sentence, the offence, gender, age and treatment needs, to a suitable facility and form of execution. Austria has closed, semi-open and open facilities as well as special facilities, for example for juvenile prisoners or for the execution of preventive measures. The choice of facility type is not a mere matter of comfort: it determines the available therapy and education offer, the practice on relaxations and thus, indirectly, the prospects of conditional release.

For longer sentences, in practice from about twelve months, the facility management draws up an execution plan under section 135 StVG. It sets out how the sentence will run: the form of execution, work or training, medical care, contact with the outside world, therapy where appropriate, levels of relaxation and preparation for release. The execution plan is not a one-sided document of the facility: the imprisoned person writes their own biography and must be heard before it is drawn up. A transfer to another facility or a deviation from the classification recommendations requires the approval of the Federal Ministry of Justice.

In practice the execution plan is one of the most important steering instruments. Anyone who brings in concrete wishes early, often already in the first execution interview, a work place in the facility, an educational measure, a planned therapy, shapes the course of the months or years ahead. Anyone who stays passive leaves the decision to the facility. From a lawyer’s perspective it pays not to treat the execution plan as an administrative formality but as the first building block of a release strategy that begins years before the first possible release.

Steps out of the facility

Which relaxations under sections 99 et seq. StVG build on one another?

Relaxations of execution are not a reward but a statutory instrument for preparing release. Sections 99 et seq. StVG recognise four staged forms that as a rule build on one another. For each level the facility examines previous conduct in execution, the social prognosis and the suitability of the concrete measure. What is decisive is not a fixed cut-off date but the prognosis: the closer the expected release moves, the sooner relaxations are granted.

Levels of relaxation of execution under sections 99 et seq. StVG with typical field of application, selection of the most important constellations
Level What it allows What needs to be evidenced to the facility
Low threshold Accompanied leave Leaving the facility accompanied by a prison officer, usually a few hours, for official, medical or important family appointments Concrete occasion and appointment, destination address, orderly conduct in execution
Building up Unaccompanied leave Leaving the facility alone with a return at a set time, for hours or for a full day Positive prognosis, a comprehensible destination with a guarantee of return, for full-day leave an accommodation commitment
Structured Outside employment Regular work outside the facility under supervision, often in cooperating businesses, with a return in the evening A fixed employer, a legally sound framework (working hours, social insurance), stable conduct in execution
Step before release Day release Independent pursuit of a job or training during the day, overnight stay in the facility, often a practical precondition for conditional release A written job or training commitment, a housing perspective, several earlier levels without objection

In practice relaxations are won by those who stage them over time and document them in writing, a consistent track over twelve to twenty-four months carries more weight than a single relaxation at the end of the sentence. Against the refusal of a relaxation the execution complaint under section 121 StVG is open, deadline two weeks from service. Electronically monitored house arrest under sections 156b et seq. StVG, by contrast, is not a relaxation but a separate form of executing the sentence outside the facility; its requirements and procedure are covered on a separate topic page.

Rights during execution

Even in custody the imprisoned person remains a holder of fundamental rights. The Sentence Enforcement Act and the constitution guarantee a range of entitlements, which however do not take effect automatically but must be actively asserted.

Execution complaint under section 121 StVG. Against decisions of the facility management the complaint to the execution chamber of the competent Regional Court is open, deadline two weeks from service or oral pronouncement. Open to complaint are, for example, refused relaxations, disciplinary decisions, transfers against the will of the person, or restrictions of visit, letter and telephone rights. A carefully reasoned complaint does not just challenge the facts but works out the legal basis.

Petition right and Human Rights Advisory Board. Alongside the execution complaint there is a petition right to the Ombudsman Board (Volksanwaltschaft), which is not tied to the complaint deadline and is effective precisely in cases of recurring practice. The Human Rights Advisory Board attached to the Ombudsman Board examines the facilities on site through its commissions. In serious cases, after exhaustion of the domestic appeals, the route to the European Court of Human Rights is open, often based on Article 3 ECHR (prohibition of inhuman or degrading treatment) or Article 8 ECHR (private and family life).

Medical care. It is ensured through the prison doctor; where specialised needs arise, external treatment is possible, for example in the prison hospital or in civilian specialist clinics. Anyone who has an existing diagnosis or therapy should bring the documents into execution early so that continuity is ensured.

Work and remuneration. Prisoners fit for work are in principle subject to the obligation to work; the activity takes place in the facility’s own enterprise or in an outside operation. The remuneration is regulated by law and low, part is paid out immediately and part is saved as a reserve for release. Anyone unfit for work is exempt from the obligation to work.

Contact with the outside world. Prisoners are entitled to regular visits and to correspondence with relatives, lawyer and other persons of reference; telephone calls are possible to a limited extent. Correspondence with the lawyer is exempt from the letter check and thus confidential.

Addiction and therapy programmes are often decisive in imprisonment, less for everyday execution than for later conditional release: an addiction or behavioural therapy successfully begun during execution is one of the strongest arguments for a favourable social prognosis. Because therapy places are limited, the application should be made early. For mental illness there is an entitlement to adequate treatment; where the prison outpatient service is not sufficient, a transfer to a specialised unit or to the execution of preventive measures is possible. More on this in the article on rights during execution.

Relaxations, transfer and electronically monitored house arrest

Beyond ongoing execution there are several instruments with which imprisonment can be adapted to the individual situation. Relaxations of execution under sections 99 et seq. StVG, from accompanied leave to day release, serve to maintain social ties and to prepare release in a structured way; as a rule they build on one another and should be planned as a staged track over many months.

The transfer to another facility under sections 134 et seq. StVG is possible, for example for proximity to home and family ties, for access to a particular therapy, to improve the prospects for relaxations in an open facility, or as a protective measure in case of conflict. The application is directed through the current facility management to the enforcement authority; a good reasoning supported by evidence markedly improves the prospects of success.

The electronically monitored house arrest under sections 156b et seq. StVG allows the sentence to be served in the person’s own home, up to a remaining duration of 24 months, and for the catalogue offences under section 156c paragraph 1 number 1 StVG up to twelve months. Housing, regular occupation and a sustainable social environment are examined; the monitoring is the responsibility of NEUSTART together with the prison facilities. These instruments are deepened on the linked topic pages; here they serve as orientation and outlook.

Conditional release and other routes to release

Conditional release under sections 46 and 47 StGB is the most common and most calculable route out of imprisonment. As a rule the execution court examines release after serving two thirds of the sentence; in particularly favourable constellations a release after half is possible, though subject to stricter requirements. The central question is always the social prognosis, whether it can be assumed that the person will commit no further offences in future. Conduct in execution, the housing situation, a work or training perspective and, for relevant prior offences, the therapeutic engagement with the offence are examined.

Conditional release rests on the idea of special prevention: the sentence is not served out of retribution but in order to prevent future offences. As soon as this purpose appears attainable, the continuation of custody is no longer justified. With release a probationary period begins, as a rule three years, in special cases up to five years, during which the court can issue directions, for example probation supervision, regular therapy or a contact ban. Breaches can trigger revocation and a return to serving the remainder of the sentence.

Against a rejecting decision of the execution court the appeal to the Higher Regional Court is open, deadline fourteen days from service. The Supreme Court has repeatedly stressed that a rejection must name concrete points of reference relating to the person; generic references to the gravity of the offence or to prior convictions do not carry on their own. Anyone who receives a rejection should read it as a challengeable legal document and at the same time clarify what can concretely be improved before the next application.

What convicted persons and relatives should concretely prepare

Imprisonment cannot be undone, but it can be shaped, and all the more effectively the earlier the preparation begins. Four points stand out as the most important, and they can also be carried by relatives.

First: use the window before the start of the sentence. Once the summons has been served, the deadline runs. In this time it must be clarified whether a deferral under section 6 StVG or electronically monitored house arrest comes into consideration, and which facility is organisationally favourable. The necessary evidence, medical reports, proof of the family and work situation, should be assembled early.

Second: secure the evidence for the release perspective. A concrete address, a written employer commitment or a training place and, for relevant prior offences, a therapy begun during execution are the supporting pillars of any conditional release. All commitments in writing, with a date and signature, because oral promises carry no weight in the proceedings.

Third: involve the probation service and the social service early. NEUSTART and the facility’s social service are not opponents but often the most important allies in building up relaxations and preparing release. Anyone who actively maintains contact avoids escalation and lays the basis for a favourable prognosis.

Fourth: document observations and communicate confidentially. Relatives often notice changes first; a written chronology helps to make grievances provable. Sensitive topics belong in the confidential correspondence with the lawyer, which is exempt from the letter check, not in ordinary post or telephone calls that may be monitored.

Frequently asked questions

What convicted persons and relatives most often ask about imprisonment.

What is the difference between imprisonment and pre-trial detention? +

Imprisonment is the execution of a custodial sentence imposed by a final judgment following conviction; it is governed by the Sentence Enforcement Act (StVG). Pre-trial detention, by contrast, secures criminal proceedings still ongoing before the final judgment; the accused is presumed innocent until a guilty verdict, and it is governed by sections 173 to 179 of the Code of Criminal Procedure. In imprisonment the question of guilt is no longer central, but the shaping of execution and the preparation of release.

What happens after the final judgment? +

The public prosecutor takes over enforcement. The competent prison facility summons the convicted person in writing to begin the sentence, as a rule within four weeks of service. In this window it can be examined whether a deferral under section 6 StVG (on health, family or economic grounds) or electronically monitored house arrest comes into consideration. Anyone who does not comply with the summons risks an order to be brought in by force.

Can the start of the sentence be deferred? +

Yes, under the conditions of section 6 StVG. The statute recognises health, family and economic grounds for deferral, each with its own burden of reasoning and threshold. The deferral buys time but does not remit the sentence. To be distinguished from it are the interruption of an execution already under way and a pardon by the Federal President, an act of grace without any legal entitlement.

What is the execution plan and why does it matter? +

For longer sentences, in practice from about twelve months, the facility management draws up an execution plan under section 135 StVG. It sets out how the sentence will run: the form of execution, work or training, medical care, contact with the outside world, therapy where appropriate, levels of relaxation and preparation for release. The imprisoned person has a right to be heard. Anyone who brings in concrete wishes early shapes the course of the months or years ahead and thereby lays the foundation for a later release.

What rights does one have during imprisonment? +

Even in custody there are enforceable rights: medical care, contact with the outside world (visits, correspondence, telephone calls to a limited extent), correspondence with the lawyer that is exempt from the letter check, religious practice and the right to complain. Against decisions of the facility management the execution complaint under section 121 StVG to the execution chamber is open, deadline two weeks from service; alongside there are the petition right to the Ombudsman Board and, after exhaustion of the appeals, the route to the European Court of Human Rights.

What are relaxations of execution? +

Relaxations of execution under sections 99 et seq. StVG are staged steps out of the facility: accompanied leave, unaccompanied leave, outside employment and day release. They serve to maintain social ties and to prepare release, and as a rule build on one another. For each level the facility examines conduct in execution, the social prognosis and the suitability of the measure. Against a refusal the execution complaint under section 121 StVG is open.

When is a conditional release possible? +

Conditional release under sections 46 and 47 StGB is as a rule possible after serving two thirds of the sentence, in particularly favourable constellations already after half (with stricter requirements). It is decided by the execution court on the basis of the social prognosis: conduct in execution, the housing situation, a work or training perspective and, for relevant prior offences, therapeutic engagement. With release a probationary period of as a rule three years begins. Against a rejection the appeal to the Higher Regional Court within fourteen days of service is open.

Can the sentence be served at home? +

Under certain conditions yes, in electronically monitored house arrest under sections 156b et seq. StVG. It is possible up to a remaining duration of 24 months; for the serious offences listed in section 156c paragraph 1 number 1 StVG it stays at twelve months. A suitable home, a regular occupation and a sustainable social environment are examined. The monitoring is the responsibility of NEUSTART together with the prison facilities.

What should relatives do first? +

Use the window before the start of the sentence and assemble the necessary evidence (medical reports, proof of the family and work situation), secure the release perspective early with written commitments on housing and work, build contact with the probation service (NEUSTART) and the facility’s social service, and document observations. Exchange sensitive topics exclusively through the confidential correspondence with the lawyer, because ordinary post and telephone calls may be monitored.
