Key legal question
Whether the appeal against the cantonal interlocutory decisions was admissible before the Federal Court
Extracted holding
The appeal was inadmissible insofar as it challenged the Obergericht decision, because the cantonal extraordinary remedy had to be exhausted for issues that could be reviewed there.
Extracted reasoning
The complained-of grounds, including arbitrariness and denial of hearing, could have been raised in the cantonal nullity complaint; therefore the cantonal instance was not exhausted.
