Question juridique clé
Whether the appeal sufficiently challenged the Federal Administrative Court's independent holding that the BAFU lacked competence to order the requested measures by decision.
Solution extraite
No. The appellants did not engage with the competence reasoning, so the appeal failed the substantiation requirement of Art. 42(2) BGG.
Motifs extraits
Where the lower judgment rests on several independent grounds, each must be specifically contested; criticism of only the standing and ECHR reasoning leaves the competence ground intact.
