Question juridique clé
Whether the recourses were admissible and had to be treated as administrative-law appeals
Solution extraite
Yes. The court held that the challenges mainly concerned federal environmental law and could be treated entirely as administrative-law appeals.
Motifs extraits
Because the plan concerned a concrete road project and the complaints focused on LPE/OPB issues, administrative-law review was available; the public-law appeal was converted where necessary.
