Key legal question
Whether the constitutional complaint could challenge the Obergericht's dismissal of the cantonal appeal against the preliminary ruling on the separation period.
Extracted holding
That part of the complaint was not entered into because the appellant did not meet the reasoning requirements; in any event, the issue was one of federal law that could have been reviewed by appeal.
Extracted reasoning
The complaint failed to address the decisive merits reasoning. Moreover, a constitutional complaint is subsidiary and was not the proper avenue for a federal-law question already suitable for appeal against a self-standing preliminary decision.
