Omnilex summary

The Administrative Tribunal interpreted Art. 15(3) LEXT to mean that buildings intended for international organizations need not be exclusively or entirely assigned to such organizations. It also held that an environmental impact study was not required for a 240-space parking lot. On the tree-felling issue, the court found that the authorization had not entered into force because it was not duly published under Art. 3(5) LCI, so opponents could still challenge it. Applying the coordination principle, the court remanded the matter to the LCI commission to reassess tree felling in light of the prior authorization. It further stated that the construction permit and tree-felling authorization must be published simultaneously to be attacked in one appeal.

Omnilex headnote

Art. 15 al. 3 LEXT; interpretation historique du régime applicable aux constructions destinées aux organisations internationales; les bâtiments concernés n’ont pas à être entièrement affectés à une organisation internationale. Art. 3 al. 5 LCI; une autorisation d’abattage d’arbres non régulièrement publiée n’entre pas en force à l’égard des tiers et demeure contestable. Le principe de coordination impose le traitement conjoint des autorisations matériellement liées, en particulier lorsque l’autorisation de construire et celle d’abattre des arbres doivent être publiées simultanément afin de permettre un recours unique; à défaut, renvoi à l’autorité compétente pour examen coordonné (consid. non précisé).

LEXT.15 al.3

Résumé

Le TA a interprété l'art.15 al.3 LEXT de la façon suivante : - les bâtiments destinés aux organisations internationales n'ont pas besoin d'être totalement affectés à une organisation internationale.

- Une étude d'impact n'est en l'espèce pas nécessaire pour un parking de 240 places.

- Faute d'avoir été régulièrement publiée (art.3 al.5 LCI) l'autorisation d'abattage d'arbres n'est pas entrée en force et les opposants à la requête pouvaient encore la remettre en cause devant la commission LCI. En application du principe de la coordination, qui vaut aussi dans le cas d'espèce, l'affaire a été renvoyée à la commission LCI pour qu'elle examine le problème de l'abattage en fonction de l'autorisation préalable (voire définitive de l'autorisation).

- L'autorisation de construire et celle d'abattre les arbres doivent être publiées simultanément pour qu'elles puissent faire l'objet d'un seul recours.

Key legal question

How should Art. 15(3) LEXT be interpreted for buildings intended for international organizations?

Extracted holding

Such buildings do not need to be entirely allocated to an international organization.

Extracted reasoning

The court adopted a historical interpretation of Art. 15(3) LEXT and held that partial use by an international organization is sufficient.

Key legal question

Whether an environmental impact study was required for a 240-space parking lot.

Extracted holding

No environmental impact study was required in this case.

Extracted reasoning

The size and characteristics of the parking facility did not trigger the obligation for an impact assessment.

Key legal question

Whether the tree-felling authorization had entered into force despite lack of proper publication.

Extracted holding

No; because it was not duly published under Art. 3(5) LCI, it had not entered into force and could still be challenged.

Extracted reasoning

A valid publication is a condition for the authorization's effectiveness against third parties.

Key legal question

Whether, under the coordination principle, the tree-felling issue had to be examined together with the construction permit.

Extracted holding

Yes; the matter was sent back to the LCI commission so that it could examine tree felling in light of the prior authorization, and if necessary the definitive authorization.

Extracted reasoning

The coordination principle applies here and requires synchronized handling of the related permits.

Key legal question

Whether the construction permit and tree-felling authorization had to be published simultaneously so they could be challenged in one appeal.

Extracted holding

Yes; simultaneous publication was required for a single appeal against both permits.

Extracted reasoning

Only concurrent publication ensures procedural unity and effective judicial review.
