A Silesian manufacturing company receives an unfavourable judgment from the District Court in Katowice. The managing director asks: "Can we appeal, and how quickly do we need to act?" The answer depends on understanding a procedural framework that is both time-sensitive and technically demanding. Miss a single deadline, and the right to appeal is lost – permanently.

Polish commercial appellate procedure is governed by the Kodeks postępowania cywilnego (Code of Civil Procedure, KPC). A party wishing to appeal a district court judgment must file a written notice of appeal within 14 days of receiving the written reasoning. The appeal is heard by the Regional Court of Appeal (Sąd Apelacyjny) or the relevant court of second instance, which reviews both the legal and factual findings of the first-instance court.

This guide sets out the full appellate process step by step: the initial notice, drafting the grounds of appeal, cost thresholds, three common business scenarios, and the mistakes that most often cause parties to forfeit their rights. Each section ends with a concrete checkpoint so your team can assess its position before engaging litigation Warsaw counsel.

What triggers the appellate window in Polish commercial courts?

The appellate window opens the moment a party receives the written reasoning of the first-instance judgment. Under Polish civil procedure, a party must first file a request for written reasoning within 7 days of the judgment's pronouncement. The court then has 14 days to deliver that reasoning. Once delivered, the 14-day appeal period begins to run – and it runs strictly.

The National Court Register (KRS) serves as the official source for verifying whether a business entity is properly represented in proceedings. Errors in representation – for example, a sole director signing the appeal when two are required by the KRS entry – can render the appeal formally defective. The court will reject a defective appeal if the defect is not cured within the time limit set in the formal deficiency notice.

The Polish Financial Supervision Authority (KNF) is relevant where the commercial dispute touches regulated activities, such as financial services or securities. In those cases, the appellate court may stay proceedings pending regulatory decisions. Parties should identify any regulatory dimension early – ideally at the first-instance stage – because raising it for the first time on appeal is procedurally restricted.

One practical point: the 14-day period is calculated in calendar days, not business days. It includes weekends and public holidays. If the deadline falls on a non-working day, it shifts to the next business day. Missing this window forfeits the right to appeal entirely – there is no automatic reinstatement, only a narrow petition for reinstatement of the deadline (przywrócenie terminu) that requires proof of no fault on the party's part.

How do you draft grounds of appeal that survive scrutiny?

The grounds of appeal are the substantive core of the entire procedure. Polish appellate courts apply a strict requirement: each ground must be clearly identified as either a procedural error (naruszenie przepisów postępowania) or an error in applying substantive law (naruszenie prawa materialnego). A general statement that the judgment is "incorrect" carries no weight. The court is bound by the grounds as formulated.

Procedural grounds must show that the error had a material impact on the outcome. If a first-instance court wrongly excluded a piece of evidence, the appeal must explain precisely what that evidence would have established and how the outcome would have differed. Courts of second instance dismiss many appeals at the threshold stage because this causal link is missing.

  • Identify each alleged error as procedural or substantive – not both simultaneously for the same fact.
  • Specify the provision of the KPC or substantive statute that was breached.
  • State the relief sought: amendment of the judgment or remittal for re-examination.
  • Include any new evidence, with an explanation of why it was not presented at first instance.
  • Calculate the value of the subject matter of appeal – this determines the court fee.

New facts and evidence are admissible on appeal only if the party could not have presented them earlier, or if the need to present them arose only after the first-instance judgment. This is a narrow exception. Appellate courts in Warsaw and Krakow have consistently refused to admit evidence that was available at trial but strategically withheld. That approach precludes a second attempt at building the factual record.

We secured a reversal of a commercial judgment worth over PLN 3.5m for a logistics client in the Mazowieckie region (spring 2025). The key was identifying a procedural error in the first-instance court's exclusion of expert witness testimony – an error the opposing party had not anticipated would be raised on appeal.

For businesses considering cross-border dispute resolution, the drafting standards differ significantly between jurisdictions. Polish appellate grounds must be precise and exhaustive at the time of filing; supplementing them later is not permitted as of right.

What are the costs and timelines for a commercial appeal?

The court fee for a commercial appeal is 5% of the value of the subject matter in dispute, with a minimum of PLN 30 and a maximum of PLN 200,000. For a claim worth PLN 1m, the fee is PLN 50,000. This must be paid when the appeal is filed – failure to pay within the deadline set in the deficiency notice results in rejection of the appeal without examination of the merits.

Timeline varies considerably by court and region. Regional Courts of Appeal in Warsaw currently list commercial appeals for hearing within 12 to 18 months of filing. Courts in smaller appellate districts may be faster – some list within 8 months – but complexity of the case and the volume of evidence can extend this. Parties should factor this timeline into any commercial decision that depends on the outcome, such as enforcement of a contract or restructuring a business.

Three business scenarios illustrate how costs and timing interact in practice:

  • Manufacturing company (PLN 2m claim): Court fee of PLN 100,000. Expected hearing in Warsaw within 14 months. Enforcement of the first-instance judgment is suspendable by application for a stay pending appeal.
  • IT services company (PLN 500,000 claim): Court fee of PLN 25,000. Regional court in Krakow listed the case within 10 months. The party obtained an interim measure protecting software licences during the proceedings.
  • Foreign investor (EUR 3m cross-border claim): Court fee capped at PLN 200,000. Proceedings involved sanctions compliance issues that required separate regulatory advice before the appellate hearing could proceed.

A stay of enforcement pending appeal is not automatic. The party must apply to the appellate court and show that enforcement would cause irreparable harm. Courts grant stays in approximately 30–40% of applications in commercial matters. Granting a stay buys time – but it also signals to the counterparty that enforcement risk is real, which can affect settlement dynamics.

What are the most common mistakes that forfeit appellate rights?

The most damaging mistake is missing the 14-day deadline for filing the notice of appeal. This is not a technicality – it is a hard cutoff. The petition for reinstatement of the deadline is available, but Polish courts grant it only where the party demonstrates it had no fault whatsoever in missing the deadline. Illness, travel, or a change of counsel rarely qualifies. The right to a second instance is lost, and the first-instance judgment becomes final and enforceable.

The second common error is filing an appeal that fails to identify the value of the subject matter. Without this figure, the court cannot assess the fee, and the appeal is formally defective. In practice, parties sometimes understate the value to reduce the fee – this is procedurally risky, as the court can raise the value on its own motion and require additional payment within a short deadline.

Our team obtained interim measures protecting assets worth over EUR 4m for a German investor's subsidiary in Lower Silesia (autumn 2025). The investor had initially filed the appeal without specifying the value correctly – a mistake corrected within the deficiency notice period, preserving the right to appeal.

A third mistake involves the representation requirement. The KPC requires that in proceedings before Regional Courts of Appeal, parties must be represented by an attorney (adwokat) or legal counsel (radca prawny). This rule of compulsory professional representation (przymus adwokacko-radcowski) applies to commercial entities. An appeal signed only by a company director – without legal counsel – will be rejected as formally inadmissible.

Parties involved in public procurement disputes should also note that the KIO appeal (appeal before the National Appeals Chamber, Krajowa Izba Odwoławcza) operates under entirely separate procedural rules with a 10-day filing window. The KIO appeal is not part of the civil appellate structure described in this guide.

What checklist should you use before filing an appeal?

A structured pre-filing review reduces the risk of procedural rejection. The following checklist covers the minimum verification steps for a commercial appeal in Poland. Each item should be confirmed in writing by the responsible legal counsel before the appeal document is submitted to the court.

  • Confirm the 14-day deadline from receipt of written reasoning – note the exact calendar date.
  • Verify the KRS entry for correct representation of the entity – two signatories if required.
  • Calculate the value of the subject matter of appeal and prepare the court fee payment.
  • Draft each ground of appeal as either procedural or substantive – never combined.
  • Confirm that compulsory professional representation is in place (attorney or legal counsel).

For disputes with a cross-border dimension – particularly those involving corporate restructuring or liquidation proceedings running in parallel – the appellate strategy must account for the interaction between the two procedures. An appeal judgment may affect the liquidation process, particularly where the disputed amount is a significant creditor claim.

Arbitration Poland practitioners should note that arbitral awards are subject to a separate challenge mechanism – the action to set aside an award (skarga o uchylenie wyroku sądu polubownego) – not the standard appellate route. A dispute lawyer advising on parallel proceedings must distinguish clearly between these two tracks from the outset.

The appellate court issues its decision either by amending the first-instance judgment, dismissing the appeal, or remitting the case for re-examination. Remittal is increasingly rare – Polish appellate courts prefer to resolve the merits themselves. Where the court amends the judgment, the amended decision is immediately enforceable. Where it dismisses the appeal, the first-instance decision stands and enforcement may proceed within days.

After the appellate court's decision, a further extraordinary remedy – the cassation appeal (skarga kasacyjna) to the Supreme Court of Poland – is available in limited circumstances. The value threshold is PLN 50,000 for most commercial matters. Cassation is not a third instance review of facts; it addresses only questions of law or serious procedural violations. Most commercial appeals end at the appellate court level.

Specific situations – where the subject matter value exceeds PLN 1m, where the case raises novel questions of law, or where enforcement is imminent – warrant early assessment of cassation prospects, even before the appellate hearing. Waiting until after the appellate judgment to consider cassation reduces preparation time to the 2-month filing window.

Frequently asked questions

Q: Can a company appeal without hiring a lawyer?

A: No. Polish procedural law requires compulsory professional representation before courts of second instance in commercial matters. The appeal must be signed and filed by a licensed attorney or legal counsel. An appeal filed directly by a company director will be rejected as formally inadmissible. This rule applies regardless of the company's size or the complexity of the case.

Q: How long does a commercial appeal in Warsaw typically take, and what does it cost?

A: The court fee is 5% of the value of the subject matter, capped at PLN 200,000. In Warsaw, Regional Courts of Appeal currently list commercial cases for hearing within 12 to 18 months of filing. Total costs – including legal fees – vary widely by case complexity, but parties should budget for a minimum of PLN 50,000 to PLN 150,000 in combined fees for a mid-value commercial dispute.

Q: Is it a misconception that new evidence can always be submitted on appeal?

A: Yes, this is one of the most common misconceptions. New evidence is admissible on appeal only if the party could not reasonably have presented it at first instance, or if the need for it arose after the first-instance judgment. Evidence that was available but not used at trial will generally be refused. Parties should present their full evidentiary case at first instance – the appeal is not a second opportunity to build the record.
