Vague summons to cure formal defects in appeal prevents rejection if directed at unrepresented party. Appeal dismissed due to unclear court instructions. Court upheld appeal based on procedural fairness.

The Supreme Court of Poland quashed the appellate court's decision rejecting the insured's appeal due to formal defects. The insured had been summoned twice to correct the appeal, but the instructions were imprecise and failed to clearly distinguish between signing the appeal and submitting specific claims. The court ruled that such vague summons cannot result in rejection when directed at an unrepresented party who may be confused by procedural nuances. Consequently, the appeal was allowed because the formal defects were not properly cured due to the court's failure to provide clear instructions.
