When the release phase begins: remaining sentence, preparation and the two-year limit

Section 145 StVG places the release phase three to 24 months before expected release. Expected conditional release and granted relaxations can also matter.

Under section 145 StVG, the release phase begins between three and 24 months before the expected release, depending on the length of the custodial sentence to be served. If conditional release is expected, the expected date of that conditional release is relevant. The release phase is therefore a statutory period before release whose beginning must be assessed using the actual sentence calculation and the enforcement prognosis.

For prisoners and their relatives, three questions matter in particular: Which release date is the relevant reference point? When does the preparation phase actually begin? And what happens to relaxations if conditional release is later refused? This article answers those questions and distinguishes them from general release planning, an application for conditional release and individual prison leave.

First assessment

Which question about the release phase applies?

01 Question 1

What is the main question?

Section 145 StVG regulates when the release phase begins. The relevant route depends on whether you need to assess the time window, a conditional release date or a relaxation that has already been granted.

Which question about the release phase applies?

01

Record the sentence, expected release date and beginning of the release phase separately.

Section 145(1) StVG provides for a period of three to 24 months before the expected release, depending on the length of the custodial sentence to be served. The provision does not state one universal number of months for every case.

As a first step, collect the judgments, crediting decisions and calculation of the expected sentence end. Only then can it be assessed which date was used for the release phase and whether the prison administration calculations can be followed.

02

Check whether the prison administration expects conditional release to take place.

If the prison governor considers that conditional release is likely, section 145(2) StVG makes the expected date of conditional release decisive. The relevant issue is therefore the concrete enforcement and file situation, not a mere hope that release might occur earlier.

For the assessment, record whether conditional release has already been considered, which sentence calculation is being used and which date appears in the documents as the expected reference point. Preparation for the release phase and an application for conditional release remain two separate questions.

03

A refusal of conditional release alone does not explain the withdrawal of a relaxation.

Section 145(3) StVG protects relaxations granted during the release phase under section 144(2) StVG: they may not be withdrawn merely because conditional release has been refused. The provision therefore prevents an automatic connection between the refusal and withdrawal of the granted relaxation.

This does not mean that every relaxation must continue regardless of other circumstances. The original approval, the specific relaxation and any new reason given by the prison administration should be documented and assessed separately.

04

Prison leave, work release and other relaxations have additional requirements.

Section 145 StVG sets the time at which the release phase begins. It does not replace the assessment of the requirements for a specific relaxation. If you need prison leave, work release or another relaxation, the purpose, scope, prognosis and applicable provision must be assessed separately.

Collect the specific purpose, desired duration, appointment documents and information about the enforcement history. The question whether the release phase has begun may be relevant, but it does not decide the application for a relaxation by itself.

The statutory beginning and time window

Section 145(1) StVG does not set one fixed date for the beginning of the release phase. Depending on the length of the custodial sentence to be served, the phase begins three to 24 months before the expected release. The time window is therefore connected to the actual sentence. The provision does not contain a universal table from which the beginning can be calculated for every prisoner without further documents.

The data must be correct before the calculation can be made: Which sentence is being served? Which periods are credited? What release date follows from the calculation? Only on that basis can the time window under section 145(1) StVG be applied meaningfully. A date mentioned in everyday communication may differ from a court or prison administration calculation.

The beginning of the release phase is different from the actual release. It opens a specific preparation period within the continuing sentence. The sentence therefore continues while the steps towards freedom are organised. The fact that the phase has begun does not automatically mean that release is imminent.

Which release date is relevant

As a rule, section 145 StVG refers to the expected release. That is the date from which the three to 24 month preparation period is calculated. If several dates are possible, the regular sentence end, credited detention and any other calculation bases must be kept separate.

Section 145(2) StVG contains a specific rule: if the prison governor considers conditional release likely, the expected date of conditional release is decisive. The provision therefore relies on a concrete assessment by the prison administration. Conditional release is not the reference point merely because it has been applied for or might theoretically be available.

For a reliable assessment, the sentence calculation, written information in the enforcement plan and any documents concerning conditional release should be read together. The key question is which date the enforcement planning actually treats as expected. Without those documents, a calculation in months remains provisional.

Three assessment points

What must be assessed separately

These questions are connected, but each has its own legal reference point.

Assessing the release phase under section 145 StVG
Question Legal reference Documents for the assessment
How long is the custodial sentence? The length determines where the beginning falls within the three to 24 month range. Judgment, sentence calculation and credited detention
Which release date is expected? The expected release usually matters; where the statutory condition is met, the expected conditional release can be decisive. Sentence calculation, enforcement plan and conditional release documents
Has a relaxation already been granted? Under section 145(3) StVG, it may not be withdrawn merely because conditional release was refused. Approval of the relaxation and written reasons for any change

The table does not replace an assessment of the actual sentence. It shows the separate reference points in the statutory rule.

An approximate calculation is rarely enough for the timing question. Keep the relevant calculations and written decisions. This makes it possible to identify which date was used and whether a later change rests on a new reason.

If conditional release is refused

Section 145(3) StVG addresses a specific situation: one or more relaxations were granted under section 144(2) StVG during the release phase and conditional release was then refused. In that situation, the relaxations may not be withdrawn merely because conditional release was refused. The refusal alone is not enough for the withdrawal.

The rule preserves the independent significance of a relaxation that has already been granted. It does not mean that every relaxation must remain unchanged in all circumstances. Other legally relevant reasons must be assessed separately. A new prison decision should therefore be checked carefully to identify the reason it actually gives and whether it simply repeats the refusal of conditional release.

The chronology and documents are important in practice: When did the release phase begin? When was the relaxation approved? When was conditional release refused? When and for what reason was the relaxation restricted or withdrawn? This chronology distinguishes an impermissible sole connection from an independently stated new reason.

Documents and next steps

For an initial assessment, a manageable set of documents is sufficient: the judgment, the sentence calculation, evidence of credited detention, the enforcement plan, the approval of a relaxation and the decision on conditional release. Add any letters in which the prison administration explains the beginning of the release phase or a later change.

Arrange the documents by date and mark each release date stated in them. This shows whether the prison administration is relying on the regular sentence end or an expected conditional release. If dates differ, the calculation should be explained in writing before legal conclusions are drawn from a single date.

This article concerns the statutory beginning of the preparation phase. General preparation of housing, documents and first steps after release is covered separately. An application for conditional release and an application for prison leave or work release also follow their own rules. These questions should therefore not be mixed into one undifferentiated application.

FAQ

Common questions about the release phase.

When does the release phase begin? +

Under section 145(1) StVG, it begins between three and 24 months before the expected release, depending on the length of the custodial sentence to be served. The exact period must be assessed using the sentence and the release date relied on.

Is the regular sentence end always the reference point? +

The rule generally refers to the expected release. If the prison governor considers conditional release likely, section 145(2) StVG makes the expected date of conditional release decisive.

Is the limit always exactly two years before release? +

No. Section 145(1) StVG provides a range of three to 24 months. The point within that range depends on the length of the custodial sentence to be served. A general calculation without the actual sentence data is therefore insufficient.

Can a relaxation be withdrawn after conditional release is refused? +

A relaxation granted during the release phase under section 144(2) StVG may not be withdrawn under section 145(3) StVG merely because conditional release was refused. Other reasons must be assessed and stated separately.

Is the beginning of the release phase the same as conditional release? +

No. The release phase is a preparation period during the continuing sentence. Conditional release is a separate decision about release before the sentence ends. The reference dates may interact, but the legal questions remain distinct.
