Question juridique clé
Whether the defendant’s building complaint constituted an unlawful competition restraint under the Cartel Act.
Solution extraite
The complaint was not a competition-related act with the required market nexus; therefore the Cartel Act did not apply.
Motifs extraits
Articles 5 and 7 KG require market- and competition-related conduct. Filing a building objection or appeal is not itself a competition act and, here, lacked the necessary market relevance and causal link to any dominant position.
