Anyone in pre-trial detention, or who has a relative in custody, quickly comes across two terms that are easily confused: detention review and detention appeal. Both are directed against pre-trial detention, but they follow different routes, have different deadlines and lead to different courts. Those who keep them apart lose no time and choose the right step.

This post explains the difference and the procedure. The detention review is the periodic check of the continuation of detention by the detention and legal protection judge at the regional court under sections 175, 176 StPO. The detention appeal is the deadline-bound remedy against a concrete detention order to the higher regional court under sections 87, 88 StPO. Both examine the same standard: urgent suspicion, ground for detention and proportionality under section 173 StPO.

Overview of all answers.

01

The detention review is the periodic check of detention by the detention and legal protection judge under sections 175, 176 StPO.

The detention review is the recurring check of whether pre-trial detention may continue. It takes place at the regional court and is decided by the detention and legal protection judge. Under sections 175, 176 StPO it runs at fixed intervals: the first detention review usually after fourteen days, then after one month and thereafter every two months. It is examined whether the urgent suspicion, a ground for detention and proportionality still exist. In addition, a release application can trigger a review hearing at any time.

What to do now: First, keep the next detention review date in view and prepare the defence for it in good time. Second, check whether more lenient measures can achieve the purpose of detention just as well, because proportionality is the most common point of leverage. Third, consider whether a release application should bring about an earlier hearing instead of waiting for the next date.

The detention appeal takes a concrete detention order up to the higher regional court, governed by sections 87, 88 StPO.

The detention appeal is the remedy against a concrete detention decision, such as the imposition or continuation of pre-trial detention. Under sections 87, 88 StPO it is decided by the higher regional court in a panel of three judges under section 33 StPO. The procedure is written; there is no oral hearing before the higher regional court. The appeal is filed at the court of first instance, that is the regional court that imposed detention, not directly at the higher regional court. It is examined whether the order holds up on suspicion, ground for detention and proportionality.

What to do now: First, examine the written copy of the detention order closely, because the deadline runs from its service. Second, align the grounds of appeal cleanly with sections 173 StPO and 5 StPO, that is with the urgent suspicion, the ground for detention and proportionality. Third, file the appeal at the regional court within the deadline.

For the initial imposition the period is fourteen days from service; for later continuation orders it is three days from pronouncement.

For the detention appeal the deadline is decisive. On the initial imposition of pre-trial detention, section 88 para 1 StPO gives fourteen days from service of the written copy of the order. For later continuation orders, section 176 para 5 StPO applies: if the order is pronounced orally in the detention review hearing, the appeal must be filed within three days from pronouncement. If you miss these deadlines, this route against the concrete order is closed. The detention review itself, by contrast, is bound by no such deadline; it runs periodically of the court’s own motion.

What to do now: First, record exactly the moment of service or oral pronouncement, because it determines when the deadline begins. Second, for a continuation order pronounced in the hearing observe the short three-day deadline and file the appeal at once. Third, in case of doubt get legal help immediately so that no deadline is lost.

Detention review and detention appeal do not exclude one another; they mesh depending on the situation.

The two routes pursue different aims and can be combined. The detention appeal challenges a particular order and leads to review by the higher regional court; it is bound by a deadline. The detention review checks the continuation of detention continuously and can be triggered at any time by a release application. Anyone who wants to act against the current order uses the appeal; anyone relying on a changed situation or new arguments often uses the detention review. In many cases a combination makes sense: the appeal against the order within the deadline and, in parallel, preparation of the next detention review.

What to do now: First, secure the appeal deadlines, because they lapse first. Second, examine whether new facts or more lenient measures support the detention review. Third, coordinate the steps with the defence so that appeal and detention review complement rather than hinder one another.

The detention review: periodic check

The detention review is the recurring check, of the court’s own motion, of whether pre-trial detention may continue. The competent body is the detention and legal protection judge at the regional court, that is the court of first instance. Under sections 175, 176 StPO it runs at fixed intervals: after the first detention decision following the detention hearing (section 174 StPO), the first detention review usually follows after fourteen days, the next after one month and thereafter every two months.

At each date the same standard is examined as on the first imposition: does an urgent suspicion under section 173 StPO still exist, is there a ground for detention and is the detention still proportionate? Proportionality in particular under section 5 StPO gains weight as detention continues, because the burden over time increases and more lenient measures come more readily into consideration. Section 178 StPO also sets maximum durations against which the examination is oriented.

The detention review is not bound by any deadline of the accused person; it takes place in any event. In addition, a release application can trigger a review hearing at any time and so bring about an earlier check. That is the right lever when the situation has changed or new arguments speak for release.

The detention appeal: challenging an order

The detention appeal is the remedy against a concrete detention decision. It is directed against a particular order, such as the imposition or continuation of pre-trial detention, and takes it up to the higher regional court. There, under section 33 StPO, a panel of three judges decides. The higher regional court is thus the appellate instance, while the detention review remains at the regional court in first instance.

Under sections 87, 88 StPO the appeal is filed at the court of first instance, that is the regional court that issued the order. It does not go directly to the higher regional court. The appeal procedure is written; there is no oral hearing before the higher regional court. It is examined whether the challenged order holds up on urgent suspicion, ground for detention and proportionality.

In substance it is worth aligning the appeal closely with the detention requirements of section 173 StPO and the proportionality of section 5 StPO. Often the most effective approach lies not in disputing the suspicion but in showing that a more lenient measure achieves the purpose of detention just as well and that detention is therefore disproportionate.

Two routes compared

Detention review and detention appeal side by side

Both routes are directed against pre-trial detention but differ in occasion, court and deadline. The overview places the most important points side by side.

Comparison of detention review (sections 175, 176 StPO) and detention appeal (sections 87, 88 StPO)
Feature Detention review Detention appeal
Occasion Runs periodically of the court’s own motion Check of whether detention may continue Directed against a concrete order
Court Instance Regional court, detention and legal protection judge Higher regional court, panel of three judges
Deadline Relevant deadline No deadline, periodic or via release application Initial imposition: fourteen days from service; continuations: three days from pronouncement
Procedure Course Review hearing at the regional court Written procedure without an oral hearing
Standard examined What is examined Suspicion, ground for detention, proportionality Suspicion, ground for detention, proportionality

The two routes do not exclude one another. Often the appeal against the order within the deadline makes sense, and in parallel the preparation of the next detention review.

Deadlines and procedure in practice

The most important practical difference lies in the deadlines. The detention appeal is deadline-bound: on the initial imposition of pre-trial detention the deadline under section 88 para 1 StPO is fourteen days from service of the written copy of the order. For later continuations after a detention review hearing, the appeal must be filed within three days from pronouncement under section 176 para 5 StPO. Anyone who misses these deadlines loses the route against the concrete order.

The detention review knows no such barrier. It takes place of the court’s own motion and can additionally be set in motion at any time by a release application. That makes it the more flexible tool when the situation changes, for instance because a ground for detention has fallen away or a more lenient measure becomes available.

In practice the two routes complement each other. Against the current order one first secures the appeal deadline, because it lapses first. In parallel one prepares the next detention review and gathers the arguments that speak for release or a more lenient measure. That way no route is left unused.

Frequently asked questions

What people often ask about detention review and detention appeal.

What is the difference between detention review and detention appeal? +

The detention review is the periodic check of the continuation of pre-trial detention by the detention and legal protection judge at the regional court under sections 175, 176 StPO. The detention appeal is the deadline-bound remedy against a concrete detention order to the higher regional court under sections 87, 88 StPO. The detention review runs of the court’s own motion, the appeal challenges a particular decision.

Which court decides on the detention appeal? +

The detention appeal is decided by the higher regional court in a panel of three judges under section 33 StPO. However, the appeal is filed at the court of first instance, that is the regional court that issued the order, not directly at the higher regional court. The procedure is written.

How much time do I have for the detention appeal? +

On the initial imposition of pre-trial detention, the deadline under section 88 para 1 StPO is fourteen days from service of the written copy of the order. For later continuations, the appeal must be filed within three days from pronouncement under section 176 para 5 StPO. Record exactly the moment of service or pronouncement.

When does the detention review take place? +

The detention review runs periodically of the court’s own motion. After the first detention decision it usually follows after fourteen days, then after one month and thereafter every two months (sections 175, 176 StPO). In addition, a release application can trigger an earlier review hearing at any time.

Can I use both routes at the same time? +

Yes. Detention review and detention appeal do not exclude one another. It often makes sense to appeal against the concrete order within the deadline and, in parallel, to prepare the next detention review or file a release application. Since the appeal deadline lapses the quickest, it should be secured first.
