Key legal question
Whether the public-law appeal could challenge allegedly arbitrary assessment of evidence despite the cantonal nullity appeal route.
Extracted holding
The arbitrariness complaint was inadmissible because the appellant had not exhausted the cantonal instance that could review it.
Extracted reasoning
Under Vaud civil procedure, arbitrary assessment of evidence could be raised by nullity appeal to the cantonal chamber of appeals; the appellant should have appealed the later cantonal decision and then filed a new federal appeal against that last-instance judgment.
