Less intrusive measures.

Proportionality as the guiding principle

Austrian criminal procedure follows a clear hierarchy: deprivation of liberty is the last, not the first, measure. Section 5 StPO (Strafprozessordnung / Code of Criminal Procedure) obliges every investigating authority and every court to choose the intervention that just barely achieves the purpose. For pre-trial detention this entails a twofold test: the court must establish that a ground for detention under Section 173(2) StPO, the risk of flight, of collusion (Verdunkelungsgefahr), of further offending or of carrying out a planned offence, is in fact present, and it must also explain why that purpose cannot be achieved by a less intrusive measure (gelinderes Mittel). The hurdle is therefore formally high, but in practice it only carries the weight that defence counsel manages to put on it.

This principle is not a mere programmatic statement: it forces the court into a concrete forecast. The question is not whether flight is conceivable, but whether the incentive to flee is so strong that even the surrender of travel documents combined with a reporting duty cannot contain it. Nor is it whether the accused could influence witnesses, but whether a non-contact order would not suffice. The more concretely the defence offers the court an alternative, the harder it becomes for the prosecution to portray pre-trial detention as having no alternative. The question of continued detention is therefore often decided on the material that lies on the table at the time of the detention hearing.

What Section 173(5) StPO provides

Section 173(5) StPO enumerates the typical less intrusive measures. The provision is deliberately broad: it ranges from a mere oral undertaking to the lodging of substantial bail. What matters in each case is whether the chosen measure, alone or in combination, can neutralise the concrete ground for detention. Different orders work against the risk of flight than against the risk of collusion, and again others against the risk of further offending or of carrying out a planned offence. The provision is not exhaustive in the sense that the court would be bound by the order of the items: it may combine measures, escalate them and adjust them over time. The statutory list comprises in particular:

• Solemn undertaking (subparagraph 1): a formal declaration not to flee, not to go into hiding and not to leave the country without the prosecutor's consent until the proceedings are concluded.
• Undertaking not to commit further offences (subparagraph 2): a supplementary assurance to refrain from criminal conduct comparable to the offence in question.
• Non-contact orders (subparagraphs 3 and 4): an undertaking not to approach particular persons (such as witnesses or co-accused) or locations and not to consume alcohol or other intoxicating substances.
• Order of residence (subparagraph 5): a direction to live at a designated place, with a designated person or in a designated facility.
• Notification of any change of address (subparagraph 6): the duty to report any change of residence without delay.
• Reporting duty with the police (subparagraph 7): periodic appearance at the competent station, daily, several times a week or weekly, depending on the incentive to flee.
• Surrender of travel documents (subparagraph 8): handing over the passport and identity card to the court or the police.
• Provisional withdrawal of the driving licence (subparagraph 9): in particular for traffic offences or where the offence is connected with the use of a vehicle.
• Direction to undergo therapy (subparagraph 10): commencement of withdrawal treatment or psychotherapy, especially for offences involving addictive substances or violence.
• Bail (subparagraph 11): a security provided by the accused or by third parties; its amount is determined by economic circumstances, the incentive to flee and the sentence to be expected.

Electronically monitored house arrest as a special variant

Electronically monitored house arrest under Section 173a StPO in conjunction with Section 156b StVG (Strafvollzugsgesetz / Austrian Prison Act) sits alongside the classical less intrusive measures and applies where these no longer suffice on their own but custodial detention would still be disproportionate. It requires a suitable dwelling capable of being technically monitored and the willingness of all other residents to accept the monitoring. In practice, electronic tagging is considered above all for longer periods of pre-trial detention, severe family hardship (small children or relatives in need of care) or accused persons with pre-existing health conditions.

The application demands a detailed plan of life: daily routine, place of work, medical appointments, persons providing support. Documented without gaps, this gives the court the basis for a sustainable forecast. A technical assessment by the competent prison administration follows, evaluating the home environment on site and installing the necessary equipment. The procedure is elaborate, but the gain in time is considerable: while tagging is in operation, employment and family ties can be maintained, which improves the later prognosis. For accused persons with a stable social environment, house arrest is often the decisive hinge between classical pre-trial detention and full liberty under conditions.

Application and ex officio review

The accused and their counsel may apply at any time for pre-trial detention to be replaced by less intrusive measures or not imposed at all. The court must additionally review of its own motion (von Amts wegen), at every detention hearing, initial imposition, detention review (Haftprüfung) and continuation, whether the purpose can in the meantime be achieved by other means. A measure once ordered remains in force as long as it serves its purpose. If the accused breaches the order, for example by ignoring the reporting duty or a non-contact order, pre-trial detention can be imposed retrospectively, or previously suspended detention enforced. A less intrusive measure is therefore not an act of grace but a vote of confidence with clearly defined obligations.

In practice the prognostic picture often shifts during the investigation: witnesses are interviewed, evidence is secured, parts of the file are closed. The risk of collusion on which the original detention decision rested often shrinks accordingly. A carefully conducted release procedure exploits precisely this shift. Counsel who continuously documents which ground bears how much weight at which point can present concrete arguments at the next review. In the end the court decides; without a prepared counter-proposal, pre-trial detention simply remains the more convenient option.

Combination and practice

In court practice a single measure is rarely relied upon; combination is the rule. Surrender of travel documents plus reporting duty plus a residence order, for instance, neutralises the risk of flight at three points at once. Where the risk of further offending is in play, a non-contact order or a therapy direction may be added; in financial offences with substantial loss, bail often forms the backbone of the package. The more closely the measures interlock, the denser the net that deprives the purpose of detention of its basis.

Whether an application succeeds is rarely decided by the statute but by the quality of the evidence put forward: a confirmed address with registration certificate, demonstrable employment with a wage slip, support from family backed by a written undertaking and, where relevant, a concrete bail offer with proof of the funds' origin. On bail in particular the court demands clarity: source, availability and economic significance of the amount for the accused must be coherent. Bail set too low misses the purpose; bail from dubious sources does the same. A well-prepared application that takes the prognostic burden off the court and makes monitoring practicable measurably improves the prospects of success, even where the court ruled differently in the first round.

What our firm does

We examine the ground for detention and the appropriate less intrusive measure in parallel: which purpose is to be secured, and with which combination of conditions can it be achieved without custody? We gather evidence early, prepare bail offers including proof of origin and lodge the application at the right procedural stage. Where appropriate, we organise contact with treatment facilities, clarify the continuation of employment with the employer and examine the conditions for electronically monitored house arrest. For relatives, often the first to learn of the arrest, we bundle the necessary steps, from obtaining a registration certificate to preparing a written assurance of support.

The placement within the wider defence strategy is set out on our pre-trial detention practice. The main proceedings, the defence in the criminal trial itself, are conducted in parallel through our sister site strafsachen.at. Less intrusive measures are not merely a plan B: they are the default that the legislature provides, if prepared early and on solid evidentiary ground.
