Question juridique clé
Whether the cantonal cassation court committed formal denial of justice by not reviewing the limitation-interruption argument under Art. 138 OR
Solution extraite
No. The meaning of 'decision of a judge' under Art. 138 OR is a matter of federal law, which the cantonal cassation court was not entitled to review; refusing to examine that point was not a denial of justice.
Motifs extraits
The complaint targeted a federal-law question that could be raised in the parallel appeal, but not in the cantonal cassation procedure governed by § 285 Abs. 1 ZPO/ZH.
