Section 600 ZPO distinguishes the consequences of missing the arbitration claim from missing a response or another procedural act. This article distinguishes the specific procedural issue from other questions of the arbitration agreement, jurisdiction and costs.
A reliable assessment requires the applicable rules, the current procedural record and verifiable dates. General information is not a substitute for reviewing the individual case.
Has the missed procedural act been identified?
This short check structures the next documents. The result is transmitted only if you actively submit the form.
Is it documented which deadline applied to the arbitration claim or response and when it expired?

What Section 600 ZPO provides
Section 600 ZPO distinguishes between a claimant’s failure to submit the claim and a respondent’s failure to respond under Section 597 paragraph 1. If the claimant does not submit the claim within the agreed or tribunal-ordered period, the tribunal terminates the proceedings. This is not a decision on the merits.
If the respondent fails to respond, the tribunal may generally continue. The claimant’s allegations are not deemed true merely because no response was filed. The tribunal may decide on the evidence obtained.
Why delivery and expiry matter
It is not enough to describe a submission as “late”. The applicable rules, the specific direction, the method of transmission and provable receipt must be identified. In institutional arbitration, the institution’s notices and the procedural timetable must also be reconciled.
The guide to preparing a VIAC request for arbitration explains why the claim and relief must be clear from the outset. For Section 600, the file must additionally show which act was due and by when.
Separate a missed claim from a missed response
The consequences are not symmetrical. Failure by the claimant to file the claim leads to termination. Failure by the respondent to answer may lead to continuation and a decision on the existing evidence. It does not create an automatic judgment.
The same framework applies to another missed procedural act, subject to the parties’ agreement. The tribunal may allow the act to be completed if it is satisfied that the default was sufficiently excused.
Prepare an explanation and application to cure
A party that missed a deadline should promptly set out what happened, when the obstacle was discovered, which act is being completed and which documents support the account. A general request for indulgence is not a reliable substitute.
The completed submission must be complete and intelligible to the other party. The right to be heard remains relevant. The article on the right to be heard and new evidence explains the connection.
Do not confuse termination with limitation
Termination under Section 600 does not answer every question about the underlying claim. Contractual forfeiture periods, limitation, interruption and the effect of a new commencement require separate review. A terminated arbitration does not preserve every deadline automatically.
If the claim is to continue, prepare a current deadline schedule and decide the next permissible step immediately. The scope of the arbitration agreement and any renewed proceedings must be assessed on the actual clause.
Documents needed for legal review
Secure the arbitration agreement, applicable rules, all procedural directions, delivery records, the timetable, the missed submission and any later filing. Add a chronology with date, time and time zone.
The broader arbitration preparation guide helps organise the record. A legal review must determine whether Section 600 applies or whether the parties agreed a different procedural mechanism.
Common questions
Does the case end automatically if the respondent does not answer? No. The tribunal may continue and decide on the evidence obtained. Silence alone does not make the claimant’s allegations true.
What happens if the claimant misses the arbitration claim deadline? Under Section 600 paragraph 1 ZPO, the tribunal terminates the proceedings if the claim required by Section 597 paragraph 1 is not filed in time. Other claim and deadline issues require separate review.
Can a missed procedural act be completed later? The tribunal may allow completion if it is satisfied that the default was sufficiently excused. The obstacle, timing and complete later filing should be documented.
Next step
Contract, arbitration clause, correspondence and deadlines should be collected. It can then be assessed whether negotiation, preservation or arbitration is central.
