CPC Art 47914 preclusion applies to all claims; later need assessment depends on case specifics.

The Supreme Court dismissed the cassation appeal filed by Telekomunikacji Polskiej SA against the Electronic Communications Office's decision regarding network interconnection. The court held that while Article 47914 § 2 of the Civil Procedure Code grants preclusion over all claims and evidence, the assessment of whether the need to cite them arose later depends on specific case circumstances. The court found that the defendant's later presentation of arguments was justified by the existence of a related pending case, rather than being a mere procedural strategy.
