New invoice evidence before the close of the hearing: when late submissions may be rejected

New factual assertions and evidence may generally be submitted in an Austrian claim proceeding until the close of the oral hearing. The court may reject a late submission, however, if it was omitted earlier through gross fault and admitting it would significantly delay the resolution of the proceeding.

Section 179 of the Austrian Code of Civil Procedure, or ZPO, therefore requires two questions to be examined together: why the material was not submitted earlier and what concrete delay its admission would cause. Lateness alone is not enough.

Anyone submitting new invoices, messages, expert material or other evidence shortly before the close of the hearing should explain the reason for the late submission and its connection with the existing case. A clear document order makes the assessment easier.

When section 179 ZPO applies to new evidence

Section 179 ZPO covers new factual assertions and evidence relating to the subject of the oral hearing. The rule therefore concerns the material already in dispute. New evidence must have a concrete connection with a relevant issue in the claim proceeding.

The provision permits new material until the close of the oral hearing. This does not create an entitlement to detailed consideration of every late submission. The court may examine whether the statutory conditions for rejection are met.

For an initial assessment, compare the existing case, the new information and its connection with the claim. An invoice, message or expert report should be allocated to a specific assertion about the debt.

What counts as a new assertion or evidence

A new factual assertion describes circumstances that have not previously been presented. New evidence is intended to support a relevant assertion, for example through an invoice, message, document or expert assessment.

A later explanation is not automatically a completely new factual submission. The key question is whether it introduces a previously missing factual basis or merely explains and supports an assertion already made. That distinction depends on the actual case file.

For several invoices, allocation by invoice number, legal basis, due date and document is useful. The article on the burden of proof in a claim lawsuit provides further guidance on assigning documents to individual claim positions.

How gross fault in the late submission is assessed

Section 179 ZPO requires that the material was omitted earlier through gross fault, particularly in light of the discussion of the factual and legal submissions under section 182a ZPO. An objectively late document is therefore not enough by itself.

The assessment includes the party’s knowledge, possible access to the information and the reason why it was not submitted earlier. A party that already had the document, could recognise its relevance and withheld it without a reasonable explanation faces a more difficult assessment.

The question remains fact-specific. A late submission may be viewed differently where the fact arose later, the evidence only became available later or its significance became apparent only from the course of the proceeding.

When admitting the evidence may cause significant delay

Even evidence omitted earlier through gross fault may be rejected under section 179 ZPO only if admitting it would significantly delay resolution. The concrete procedural position is decisive.

Delay may arise where the opponent needs to respond to a new factual core, an additional witness must be heard or an expert report becomes necessary. Whether that consequence is significant cannot be determined from the size of the document alone.

A party seeking rejection should identify the additional time and steps required. The party submitting the material can explain why it can be discussed without a material interruption or extension of the proceeding.

How an application and the hearing date interact

The court may reject new material on application or of its own motion. An opponent’s application should identify the late fact or evidence and give separate reasons for gross fault and the expected significant delay.

Timing in the proceeding matters. Section 179 ZPO refers to the close of the oral hearing. A submission shortly before that point therefore calls for a prompt response and a clear record of the content, access and possible consequences.

A party receiving new documents should do more than forward them. The connection with the existing case should be explained. This helps the court assess whether the material can be discussed without significant delay.

What a rejection order means for the claim

If late material is rejected, it may not be considered in the proceeding in the intended manner. The order should allocate the effect to the specific new submission.

Section 179 ZPO expressly provides that a separate legal remedy against the order is not admissible. This procedural consequence is separate from the substantive question whether the claim exists and what the other evidence proves.

Rejection therefore does not replace a complete review of the claim. Existing invoices, payments, due dates and other evidence must still be assessed on their own terms. A separate balance is also useful where the debtor has made a partial objection, as explained in the article on the undisputed balance after a partial objection.

How to prepare new invoice evidence

Before submitting the material, prepare a short chronology. It should state when the claim arose, what has already been asserted, when the new evidence became known and available, and when it was forwarded to the court and opponent.

Each new document should be linked to the assertion it supports. For a private loan, agreement, payment, due date and repayments should be documented separately. The guide to recovering a private loan illustrates this allocation in a different factual setting.

Finally, describe the expected procedural effect. Does the opponent need only a short response, or will further evidence be required? This information helps assess whether section 179 ZPO’s significant-delay requirement is met.

How the law firm reviews the next step

BRANDAUER Rechtsanwälte first organise the existing case, the new factual core and the related evidence. The review then establishes when the information was known and available and why it was only submitted now.

The next question is the concrete procedural effect. The required responses, evidence and hearing steps are identified, together with whether they would significantly delay resolution.

For an initial review, provide the procedural correspondence, the new document, a chronology and a short explanation of the expected time needed. This allows the possible consideration, rejection or other procedural response to be assessed.
