Question juridique clé
Whether the public-law appeal was admissible against the cantonal interlocutory decision
Solution extraite
The interlocutory decision caused no irreparable legal harm and the public-law appeal would normally be inadmissible; admissibility followed only because the nullity appeal was admissible.
Motifs extraits
Under Art. 87 OJ, irreparable legal harm was not shown. However, a public-law appeal may accompany an admissible nullity appeal against the same interlocutory decision.
