Anyone in pre-trial detention is often confronted with the ground of flight risk. The fear that someone will evade the proceedings sounds simple, but section 173 para 2 no 1 StPO requires specific facts. A defence against flight risk lives off making ties to Austria visible and offering milder safeguards.

This post explains the levers. According to settled case law a high sentence threat alone does not carry flight risk. What matters are concrete facts on residence, family and work as well as residence status. Instead of detention section 173 para 5 StPO provides less restrictive measures such as reporting duty, passport deposit or bail. The order can be challenged before the Higher Regional Court.

Flight risk often falls away where the defendant credibly demonstrates ties to Austria.

Flight risk under section 173 para 2 no 1 StPO requires specific facts giving reason to fear that the accused will evade the proceedings. According to settled case law a high sentence threat alone does not suffice. The defence must therefore make visible concrete anchors in Austria that stand against flight.

What to do now: First, present a current registration certificate and a tenancy or ownership record. Second, document an active employment contract or job offer and existing health insurance. Third, evidence family ties such as marriage, children or care of relatives with birth certificates, school confirmations and registration data.

Reporting duty, passport deposit, residence requirement or bail can replace detention as a less restrictive measure.

Under section 173 para 5 StPO pre-trial detention is to be avoided where the purpose can be achieved by a less restrictive measure. For flight risk passport deposit, reporting duty with the police, a residence requirement and bail are particularly relevant. These measures bind the accused to Austria and secure their presence in the proceedings.

What to do now: First, deposit the passport and any further travel documents with the court. Second, offer a concrete reporting duty, for instance two or three times a week at the nearest police station. Third, quantify a realistically affordable bail and explain financing through relatives or sureties.

Detention must remain proportionate; sentence threat alone does not carry flight risk.

Under section 173 para 1 StPO pre-trial detention may only be imposed or continued where it is not disproportionate to the significance of the case and to the expected sentence. With growing time served the argument grows that an expected remaining sentence no longer carries flight risk. Individual life circumstances and the previous history are also to be weighed.

What to do now: First, calculate the days already spent in detention precisely and contrast them with a realistically expected sentence. Second, assess the course of the proceedings so far and the likely remaining duration. Third, raise individual aspects such as first-time status, clean record and stable social ties.

A detention order can be appealed to the Higher Regional Court; in parallel a release motion can be filed.

The decision imposing or continuing pre-trial detention can be appealed to the competent Higher Regional Court. The appeal must be lodged within three days from service of the order. In parallel a reasoned release motion can be filed at any time where new facts or evidence place flight risk in a new light.

What to do now: First, secure the three-day appeal deadline and examine the order systematically for specific facts. Second, in parallel file a release motion offering a less restrictive measure. Third, by the next scheduled detention hearing prepare fresh evidence on ties to Austria.

The ground of flight risk under section 173 para 2 no 1 StPO

Under section 173 para 2 no 1 StPO pre-trial detention is admissible where, on the basis of specific facts, it must be feared that the accused will evade the proceedings because of the magnitude of the threatened sentence or for other reasons. What is decisive are specific facts, not bare assumptions, and they must bear the concern of a serious risk of flight.

Settled case law requires that the threat of sentence alone does not establish flight risk. Anchors in the person’s life are needed, such as missing ties at home, lived foreign connections or preparatory steps for leaving the country. The defence must therefore examine the case file and the lived reality of the accused comprehensively.

The assessment is made from the perspective of the moment of the order. With every day in detention, every new state of evidence and every change in personal circumstances the concern may have to be assessed differently. Periodic review of detention serves precisely to align that assessment with the case file.

Defence strategy: prove ties and offer a less restrictive measure

The most effective defence against flight risk is a twofold one. On the one hand ties to Austria must be evidenced by documents, on the other a properly dimensioned less restrictive measure must be offered. Both tracks support each other and remove the court’s concern that the accused might evade.

Ties include current residence, lived family, work or education as well as health insurance and residence status. A registration certificate alone rarely suffices; the defence should paint a complete picture with documents. Care for relatives, school-age children in Austria and long-standing employment are strong arguments.

Suitable measures are reporting duty with the police, deposit of the passport, residence requirement and bail. Bail is to be quantified concretely and to be deposited or backed by surety. The more precise the offer, the more likely the court will accept the less restrictive measure instead of detention.

Frequently asked questions

What people often ask about rebutting flight risk.

Is a high sentence threat enough for flight risk? +

No. According to settled case law the sentence threat alone does not carry flight risk. Specific facts are needed that give cause to fear flight, such as missing ties in Austria or concrete preparations to leave the country.

Which evidence convinces the court? +

Current registration certificate, tenancy or ownership record, employment contract, birth and marriage certificates, school confirmations for children, care allowance decisions and residence permit. A coherent picture is more convincing than isolated documents.

What is a less restrictive measure for flight risk? +

Under section 173 para 5 StPO reporting duty, passport deposit, residence requirement and bail are available. The offer must be concrete and realistically affordable; a mere willingness is not enough.

How high should bail be? +

Bail must relate to the threatened sentence and to the financial situation. It must be quantified concretely and either deposited or backed by surety, otherwise the offer runs empty.

What remedies are available? +

The detention order can be appealed to the Higher Regional Court within three days. A release motion is possible at any time. By the next scheduled detention hearing fresh evidence on ties should be ready.
