Questione giuridica chiave
Whether the complaints against the unapproved access plan and its regulations were admissible in federal court
Decisione estratta
The objections directed at the plan content were inadmissible because the access plan had not yet been finally approved and had no binding legal effect.
Motivazione estratta
Only finally effective cantonal acts or legally binding federal-administrative dispositions can be reviewed; an unapproved municipal planning draft is not yet challengeable on its merits.
