Question juridique clé
Whether Art. 32d(5) USG requires the public authority to bear investigation costs because only the remaining area A was found contaminated.
Solution extraite
No. Cost transfer to the public authority applies only when the whole registered or intended-to-be-registered site proves uncontaminated; a merely reduced contaminated perimeter is insufficient.
Motifs extraits
The site was not wholly uncontaminated. The technical investigation still confirmed a contaminated residual area A, so the statutory condition for public funding of investigation costs was not met.
