Question juridique clé
Whether the complaint against the cantonal supervisory decision was admissible despite the asserted nullity of the decision.
Solution extraite
No substantiated ground of nullity was shown; the court found no apparent nullity ground and therefore could not enter into the complaint.
Motifs extraits
The appellant merely invoked nullity in a cursory way and did not substantiate it as required. Without a cognizable nullity ground, the Federal Supreme Court could not review the complaint on the merits.
