In an entry ban procedure, the authority may appoint a non-official expert. Under section 53(1) of the Austrian General Administrative Procedure Act (AVG), a party may challenge that expert if it credibly states circumstances that cast doubt on expertise or impartiality.

The statute identifies the expert's examination as the ordinary point for raising the challenge. A later challenge requires a specific explanation. The expert's role, the actual concern and the procedural record therefore matter.

Does section 53 AVG fit your situation?

First identify the expert's role. The assessment then separates the reason for concern from the timing.

01 Question 1

How does the file describe the expert?

Section 53 AVG distinguishes official experts from other experts.

All paths at a glance

Overview of all answers.

01

Section 53 AVG refers official experts to section 7 AVG.

Check the formal designation in the appointment and file. Challenging other experts under section 53 AVG is a different route from dealing with an official expert.

02

Identify the expert's role before choosing a legal route.

Check the appointment, instructions and report for the person's designation and function. Without that step, it is not possible to say with confidence whether section 53 AVG is the right route.

03

A disputed conclusion alone does not establish a lack of expertise.

Identify the exact assumption, method or fact you consider wrong. If the question is what facts the BVwG should establish, see the guide to evidence applications in entry ban proceedings.

04

The expert has not yet been examined.

If you have specific facts about expertise or impartiality, the ordinary point for raising the challenge is before the expert is examined. Explain how the facts relate to the question assigned and include the records available to you.

05

A reason discovered later needs a credible explanation.

Section 53(1) AVG allows a later challenge only in limited circumstances. Record when and how you learned of the reason and keep the documents that support that chronology.

06

The statute requires an insurmountable obstacle.

For a late challenge, the party must credibly show that an insurmountable obstacle prevented a timely objection. Describe the obstacle, how long it lasted and how it prevented the earlier step.

07

A known reason with no insurmountable obstacle does not fit the late exception.

The wording permits a later challenge only if the reason was previously unknown or an insurmountable obstacle prevented a timely challenge. Have the file and dates reviewed rather than relying on an exception that the known facts do not support.

Which experts fall under section 53 AVG?

Section 53(1) AVG distinguishes official experts from other experts. Section 7 AVG applies to official experts. Other experts are excluded if one of the grounds in section 7(1), items 1, 2 or 4 AVG applies. A party may also challenge them if credible circumstances cast doubt on expertise or impartiality.

The classification turns on whether the person is an official expert or another expert. The fact that an authority issued the instructions does not answer that question on its own. Check the appointment and the expert's role in the file. Concerns about the person handling the decision are separate from a challenge to an expert.

How must a concern about expertise be connected?

Explain why the expert's knowledge may not match the particular question assigned. Set out the task, the relevant field and the available information about the person's training or professional experience. Such records can support a concern, but they do not automatically require the expert to be removed.

A different conclusion or an unfavourable report does not, by itself, show a lack of expertise. Identify the assumption, method or factual basis you dispute. If the issue is what identity evidence proves, the separate guide to identity deception in immigration proceedings addresses that question.

What point in time does section 53 AVG name?

Section 53(1) AVG names the period before the expert is examined as the ordinary point for a challenge. It sets no fixed number of calendar days. The wording instead refers to a procedural step.

Receipt of a written report does not by itself show whether the expert has been examined for this purpose. Check the notice, minutes and procedural record before assessing the timing. Once the reason is known, organise the challenge around that reason and the next procedural step.

When can a challenge be raised later?

After the examination, section 53(1) AVG allows a challenge only if the party credibly shows either that the reason was not known earlier or that an insurmountable obstacle prevented it from being raised in time. Saying only that the challenge was prepared later does not address that statutory condition.

Set out the sequence: when did the reason become apparent, how did you learn of it and what obstacle prevented an earlier challenge? Keep records that support those dates. Whether the explanation is sufficient depends on the circumstances that can be established.

How does the authority decide the application?

Under section 53(2) AVG, the decision on a challenge is made by procedural order (Verfahrensanordnung). The provision identifies the form of the decision. It does not predict whether a particular application will succeed.

Keep the challenge, supporting records and procedural chronology distinct. If the case also concerns what evidence the BVwG should take, that issue needs its own explanation. The guide to evidence applications before the BVwG addresses that separate step. To review the decision, minutes and evidence already in the file, see file inspection in entry ban proceedings.

FAQ

Questions about challenging an expert

Does section 53 AVG apply to official experts in the same way? +
No. Section 53(1) AVG refers official experts to section 7 AVG. Check the formal appointment and the person's role in the proceedings before applying the separate route for other experts.
Do I have to prove the lack of expertise in full? +
Section 53(1) AVG asks the party to make credible circumstances that call expertise or impartiality into doubt. Explain how the facts relate to the assigned question and identify any supporting records.
Is there a fixed number of days to challenge an expert? +
Section 53(1) AVG gives no day count. The ordinary point is before the expert is examined. A later challenge is subject to the conditions stated in the provision.
Is an unfavourable expert report enough? +
An unfavourable result alone does not establish a lack of expertise. State specific circumstances that call the person's expertise or impartiality into doubt.
What must be explained if the challenge is late? +
The party must credibly show that the reason was previously unknown or an insurmountable obstacle prevented a timely challenge.
