Question juridique clé
Whether the appellant had standing to bring a civil-law appeal against the cantonal order
Solution extraite
The appellant was named in the order but was not affected in his legal position and therefore lacked a legally protected interest in its annulment or amendment.
Motifs extraits
Under Art. 76(1)(b) BGG, the appellant must be specially affected and have a protected interest. Because the order concerned only a cost advance for B.________, no impairment of A.________'s legal position was shown.
