Key legal question
Whether the complaint against the Zivilgericht Basel-Stadt was admissible despite not exhausting cantonal remedies.
Extracted holding
It was inadmissible because an appellate supervisory complaint was still available in Basel-Stadt.
Extracted reasoning
A delay- or denial-of-justice complaint to the Federal Supreme Court requires exhaustion of available cantonal remedies; the applicant could still raise supervisory complaint before the Appellationsgericht.
