It is almost implied that the environmental law must be uniformly applied cross-border in order to be effective. I attach below a new case from the CJEU C-258/11, only the AG Opinion has been delivered. Except the reinforcement of the importance of the precautionary principle and the specification that an effect which is permanent or long lasting must be regarded as an adverse one in the light of the named principle, the issue of admissibility is also interesting.
It is obvious that nature can not be divided in different jurisdictions, but the reality is that we all live on a political map. A very formalistic interpretation of the admissibility issue would lead to the conclusion that the question was inadmissible.
Economic Freedoms by analogy
According to settled case-law, the provisions of the Treaty do not apply to purely internal situations in a Member State (see, to that effect, Joined Cases C‑54/88, C‑91/88 an C‑14/89 Nino and Others [1990] ECR I‑3537, paragraph 11; Case C‑134/94 Esso Española [1995] ECR I‑4223, paragraph 17; and Case C‑389/05 Commission v France [2008] ECR I‑5397, paragraph 49).
However, even in a purely internal situation the Court’s answer may nevertheless be useful to the referring court, in particular if its national law required it to grant the same rights to an own national as those which a national of another Member State in the same situation would derive from European Union law. see, Joined Cases C‑570/07 and C‑571/07 Blanco Pérez and Chao Gómez [2010] ECR I‑4629, paragraph 39; Case C‑393/08 Sbarigia [2010] ECR I‑6333, paragraph 23; and Case C‑245/09 Omalet [2010] ECR I‑0000, paragraph 15
Where domestic legislation adopts for purely internal situations the same solutions as those adopted in Union law, it is for the national court alone, in the context of the division of judicial functions between national courts and the Court of Justice under Article 267 TFEU, to assess the precise scope of that reference to Union law, the consideration of the limits which the national legislature may have placed on the application of Union law to purely internal situations being a matter for the law of the Member State concerned and, consequently, falling within the exclusive jurisdiction of the courts of that Member State.
