Questão jurídica principal
Whether the cantonal court could validly sit as sole instance under CPC/LTF.
Decisão extraída
Yes; because federal law allows a single cantonal instance and Geneva law made use of that possibility.
Fundamentação extraída
Art. 7 CPC combined with the revised wording of the LTF covers cases where federal law permits a cantonal single-instance court and cantonal law provides for it.
