Arbitrator unable to continue: how early termination is reviewed
13 August 2026 | Mag. Bernhard Brandauer, Rechtsanwalt
Arbitrator unable to continue: Austrian ZPO section 590 on resignation, termination and court application.
Arbitrator unable to continue: how early termination is reviewed addresses a narrow point in Austrian arbitration. The article explains the issue on the basis of the verified ZPO source and shows which documents should be secured first.
The review question is: What should be done if an arbitrator resigns or does not perform the tasks? The source basis is § 590 ZPO. The article is general information and does not replace review of the individual file.
The article is deliberately not a general arbitration guide. It focuses on early termination of the arbitrator mandate rather than bias or challenge and the practical procedural risk behind it.
Which point should be reviewed first?
The short check structures your starting point. The result is transmitted only if you actively submit the form.
Is the arbitrator problem already documented?
Prepare prompt detailed review
The starting data is available. Clause, procedural stage, deadlines and objective should now be checked against the documents.
- Document the inability in writing
- Check the appointment rule
- Record delay
Organise documents first
Missing documents make the assessment uncertain. A short chronology with contract, correspondence and proof is useful.
- Document the inability in writing
- Check the appointment rule
- Record delay
Secure first orientation
Before tactical steps, clarify whether arbitral tribunal, state court, settlement or enforcement is central.
- Document the inability in writing
- Check the appointment rule
- Record delay
What the issue is about
If an arbitrator can no longer continue, delay, deadline problems and disputes about replacement may arise. Section 590 ZPO regulates when the mandate ends and when a court application may be considered.
For practice, the procedural position must be separated first. Contract, clause, correspondence, deadlines and steps already taken should then be ordered before a response or application is prepared.
Legal basis and review step
The RIS source for section 590 ZPO refers to party agreement, resignation and a court decision where the arbitrator is unable or fails to act. The source states that no appeal is available against that decision.
The source does not create an automatic answer for every case. Clause wording, seat, procedural rules and current stage must be read together.
Typical preparation mistake
A common mistake is treating the problem as purely organisational. Legally, it must be checked whether an agreed procedure applies and whether a court application is needed.
A short chronology is useful. It should show not only dates but also which document was transmitted and how the other side reacted.
Difference from other arbitration issues
This article deepens one practical scenario. The wider structure is explained on the topic pages about arbitration clauses, preparing arbitration and enforcing arbitral awards.
The separation avoids duplicate core content. The purpose here is quick classification of a narrow problem based on the verified ZPO source.
What to prepare for an enquiry
Helpful documents are the contract, arbitration clause, latest letters, proof of service, deadlines, a short chronology and the intended commercial outcome.
Important documents are the appointment record, arbitration agreement, correspondence on the inability and documents on previous delay.
Common questions on arbitration
Does the mandate end automatically after every resignation? Section 590 ZPO names resignation as a termination event. Replacement still has to be checked under the agreement or the law.
Can the point be corrected later? That depends on the procedural stage. Some objections must be raised early. Other points can be corrected or reviewed only within narrow limits after the award.
Which documents should be sent first? Send contract, arbitration clause, amendments, proof of service, deadlines and a short chronology. Confidential details should be coordinated first.
Next step
Contract, arbitration clause, correspondence and deadlines should be collected. It can then be assessed whether negotiation, preservation or arbitration is central.
