Supreme Court dismisses appeal due to res judicata when same claim was previously adjudicated between identical parties.

The Supreme Court of Poland dismissed the applicant's cassation appeal against a final judgment denying her family pension. The court found that the applicant had previously filed a lawsuit for alimony against her deceased husband, which was validly discontinued, establishing a final judicial determination on her lack of alimony rights. Consequently, the court ruled that the current pension claim constituted the same legal issue between the same parties, triggering the principle of res judicata under the Code of Civil Procedure. The appeal was rejected because the matter had already been conclusively decided in the earlier proceedings.
