Questão jurídica principal
Whether the revocation of the precarious public-domain use permit was lawful under nature-protection law.
Decisão extraída
Yes. The bridge caused a relevant impairment of the protected alluvial biotope, and its removal was an adequate and proportionate protection measure.
Fundamentação extraída
The court held that the biotope had to be assessed in its existing state, that the bridge created disturbance and fragmentation, and that no equally effective less severe measure appeared available.
