A final criminal judgment is meant to stand. That is the very purpose of legal finality. Yet a judgment can be wrong, because an important piece of evidence only surfaces later or because a witness lied in the proceedings. For such cases Austrian criminal law provides the reopening of proceedings, an extraordinary remedy that exceptionally reopens a concluded case.

This article explains when proceedings may be reopened in favour of a convicted person under Section 353 StPO. It distinguishes this from reopening discontinued proceedings under Section 352 StPO and reopening after a final acquittal under Section 355 StPO. It also places the appeal, the plea of nullity and renewal under Section 363a StPO in context. This is general information, not advice in an individual case.

Is reopening an option for you?

Four starting situations, one clear next step.

Whether a final case can be reopened depends on the ground and on the right remedy. Choose the situation that applies to you to see a first assessment and the next concrete step.

01 Question 1

What is your situation?

The applicable provision depends on how the proceedings ended: conviction, acquittal or discontinuation.

01

New facts or evidence: assess reopening in favour under Section 353 StPO.

If new facts or evidence emerge after the final judgment, reopening in favour of the convicted person under Section 353 StPO comes into consideration. The requirement is that the facts or evidence were unknown to the court when the judgment was delivered and that they appear suitable, alone or in connection with the earlier evidence, to justify an acquittal or a conviction under a milder law. From a legal perspective, the first question is whether the new material really reaches this suitability, because only then is the application promising.

A merely different assessment of the evidence is not enough; the court reviews the strength of the material strictly. Careful preparation of the new material and its connection with the file are therefore decisive.

02

False evidence: assess reopening under Section 353 no. 1 StPO.

If the judgment rests on a piece of evidence that turns out to be false or forged, for example a false statement, a forged document or an incorrect expert opinion, Section 353 no. 1 StPO opens the way to reopening. The same applies where the judgment was brought about by bribery or another criminal act. From a legal perspective, it must be clarified whether the falsity can be proven and whether it actually influenced the judgment.

Here it depends on showing that this very flawed piece of evidence was decisive for the finding of guilt. Only then does the ground for reopening hold.

03

Violation of rights: assess renewal of the proceedings under Section 363a StPO.

Anyone alleging a violation of the European Convention on Human Rights in the criminal proceedings, for example a breach of the right to a fair trial, can pursue the renewal of the proceedings under Section 363a StPO. This remedy applies after a judgment of the European Court of Human Rights establishing a Convention violation. Under certain conditions the Supreme Court also admits an application without a prior Strasbourg judgment. From a legal perspective, the specific Convention violation must be named precisely.

The Supreme Court decides on the renewal. Unlike the classic reopening, it is bound by strict deadlines and formalities, which is why an early assessment is important.

Section 355 StPO after acquittal, Section 352 StPO after discontinuation.

After a final acquittal, the prosecution or a private prosecutor may apply to reopen the case to the defendant’s detriment under Section 355 StPO. Section 355 permits this only on the grounds listed in Section 352(1). It does not add a requirement that new facts establish a strong suspicion of a serious crime. Section 352(1) also requires that the offence has not become time-barred.

A discontinuation is a different outcome and is governed by Section 352 StPO. That provision covers certain discontinuations by court order and withdrawals from prosecution that are not merely provisional. A private prosecutor may apply only in the case under Section 215(2) StPO. First identify whether the earlier proceedings ended in an acquittal or a discontinuation, and which reopening ground is relied on.

What reopening means

The StPO provides several routes for reopening proceedings. Section 353 StPO concerns reopening in favour of a convicted person after a final judgment. Section 352 StPO governs reopening of certain discontinued proceedings against the accused. Section 355 StPO concerns a final acquittal and refers to the grounds in Section 352(1).

An appeal and a plea of nullity challenge a judgment before it becomes final. Sections 352 and 355 StPO address different outcomes: discontinuation or a final acquittal. Reopening in favour under Section 353 StPO requires its own statutory ground, such as new facts or evidence or a false evidentiary basis.

No rigid application deadline is provided for reopening in favour under Section 353 StPO. An application may be made even after the sentence has been fully served. After the convicted person’s death, close relatives may apply to restore the person’s good name, subject to the statutory conditions.

The grounds for reopening in favour

Reopening in favour of the convicted person is governed by Section 353 StPO. It comes into consideration above all on two grounds.

False or fraudulently obtained foundations (Section 353 no. 1 StPO). If the judgment rests on a forged document, a false statement, an incorrect expert opinion, or if it was brought about by bribery or another criminal act, reopening is possible. What is decisive is that this flawed piece of evidence was decisive for the finding of guilt.

New facts or evidence (Section 353 no. 2 StPO). If facts or evidence are brought forward that were unknown to the court when the judgment was delivered, the proceedings can be reopened. The requirement is that, alone or in connection with the evidence already taken, they appear suitable to justify an acquittal or a conviction under a milder criminal law.

Evidence is new if the court did not use it in the judgment. A merely different assessment of evidence already known is not enough. The court reviews the suitability of the new material strictly, which is why careful preparation matters.

Remedies

Reopening, appeal, plea of nullity and renewal compared

Which remedy fits depends on whether the judgment is already final and on what the challenge is based. Our focus page on remedies in criminal procedure offers a broader overview.

Comparison of the main routes against a criminal judgment, with the point of reference and the competent court
Remedy When Point of reference Note from a legal perspective
Sections 280 ff, 294 StPO Appeal and plea of nullity Before the judgment becomes final Ordinary remedies against the not yet final judgment Mind the short notice periods from the pronouncement of the judgment; the further route is decided here.
Section 353 StPO Reopening in favour After the judgment has become final New facts or evidence or a false evidentiary basis Not bound by a rigid deadline, possible even after the sentence has been served.
Section 352 StPO Reopening after discontinuation After a court order or a withdrawal from prosecution that is not merely provisional Limitation has not expired and one of the grounds in Section 352(1) applies A private prosecutor may apply only for a discontinuation under Section 215(2) StPO (Section 352(2)).
Section 355 StPO Reopening after acquittal After a final acquittal Only on the grounds in Section 352(1) No additional serious-crime suspicion threshold; check limitation.
Section 363a StPO Renewal of the proceedings After finality Violation of the European Convention on Human Rights Decision by the Supreme Court, strict deadlines and formalities.

Distinction from the ordinary remedies

Reopening must not be confused with the ordinary remedies. Appeal and plea of nullity are directed against a judgment that is not yet final. They must be filed shortly after the pronouncement of the judgment and are the first line of defence against a finding of guilt.

Only once these routes are exhausted or their deadlines have passed does reopening come into consideration as an extraordinary remedy. It is not a second attempt at assessing the evidence but requires an independent ground for reopening.

Alongside this stands the renewal of proceedings under Section 363a StPO. It targets violations of the European Convention on Human Rights and leads to a decision of the Supreme Court. Which of these routes is open in the individual case depends on the stage of the proceedings and on the defect asserted.

Reopening to the detriment

A final acquittal and a discontinuation are different outcomes. After an acquittal, Section 355 StPO allows the prosecution or a private prosecutor to apply for reopening to the defendant’s detriment only on the grounds in Section 352(1). Section 355 does not add a requirement of a strong suspicion of a serious crime.

Section 352(1) requires that the offence has not become time-barred. It lists a discontinuation brought about by forgery, false testimony, bribery or another criminal act (no. 1), and a later confession or new facts or evidence that appear suitable to suggest a conviction under Section 210(1) StPO (no. 2). The discontinuation described in no. 1 remains distinct from an acquittal.

Section 352 StPO applies directly to certain discontinued proceedings: those closed by court order or by a withdrawal from prosecution that is not merely provisional under Chapter 11. Under Section 352(1), the prosecution may apply to reopen the proceedings in these cases. The provision excludes continuation of the investigation under Sections 193, 195 and 196 StPO. Under Section 352(2), a private prosecutor may apply only for a discontinuation under Section 215(2) StPO.

For a specific application, check how the earlier proceedings ended, the ground relied on and limitation. The statute of limitations may prevent renewed prosecution. The official wording is available in RIS for Section 352 StPO and Section 355 StPO.

Procedure and jurisdiction

An application for reopening is decided by the court in a separate procedure governed by Sections 352 ff StPO. The application must set out the ground for reopening and the supporting evidence specifically.

If the reopening is granted, the proceedings revert to the earlier stage. Depending on the situation, a new main trial takes place in which guilt and sentence are decided again. Until then, the original judgment remains in force in principle.

The renewal under Section 363a StPO, by contrast, is decided by the Supreme Court. Because of the different routes and the partly strict deadlines, the choice of the right remedy should be made early and carefully.

Reopening is not a second trial on suspicion. It requires a concrete statutory ground, above all new and robust evidence. Whether the ground holds is decided by its suitability to genuinely shake the original judgment. How criminal proceedings work in the first place is set out in our article What to do after a criminal complaint in Austria.

Frequently asked questions

What you need to know about reopening in Austria.

Is there a deadline for reopening? +

No rigid application deadline is provided for reopening in favour of a convicted person under Section 353 StPO. This does not apply to every form of reopening. For applications under Sections 352 and 355 StPO, it is particularly important to check whether the offence has become time-barred. Renewal under Section 363a StPO has its own time limits.

Is a new witness enough for reopening? +

New evidence suffices only if it is suitable, alone or in connection with the earlier evidence, to justify an acquittal or a milder conviction. The court reviews this suitability strictly. A merely different statement on circumstances already known is generally not enough.

How does reopening differ from an appeal? +

The appeal and the plea of nullity are ordinary remedies against a judgment that is not yet final and must be filed shortly after the pronouncement. Reopening only takes effect after the judgment has become final and requires its own statutory ground for reopening.

Can an acquittal be reopened? +

After a final acquittal, Section 355 StPO permits reopening to the defendant’s detriment only on the grounds in Section 352(1). The law adds no separate requirement of a strong suspicion of a serious crime. A discontinuation is governed separately by Section 352 StPO.

What does the renewal under Section 363a StPO achieve? +

The renewal serves to remedy violations of the European Convention on Human Rights. It comes into consideration after a judgment of the European Court of Human Rights, but under certain conditions the Supreme Court also admits an application without a prior Strasbourg judgment. The Supreme Court decides on the renewal.

What happens if reopening is granted? +

If the application is granted, the proceedings revert to the earlier stage. Often a new main trial follows in which guilt and sentence are decided again. Until the new decision, the original judgment remains in force in principle.
