Question juridique clé
Whether the railway project required a formal environmental impact assessment
Solution extraite
The project did not require a formal UVP because it was an expansion/replacement of an existing railway link, not a new railway line under the UVPV, and its cost did not exceed the threshold for other railway installations.
Motifs extraits
Only new railway lines fall under automatic UVP duty; this link merely replaces an old line and is therefore treated as an expansion. In any event, the environmental effects were sufficiently examined in the planning procedure.
