“Documenta” is one of the most important exhibitions of modern and contemporary art which takes place in Kassel, Germany every five years. In a judgement of May 4, 2010, OLG Frankfurt (Case 11 U 70/09) decided that the managing company of the event is allowed to ban external suppliers, in particular tour operators, from offering guided tours at the exhibition: the company had a legitimate interest to cover the costs of the exhibition by providing its own guided tours which constituted a justified reason to exclude external organisers. The ban could not be regarded a misuse of a market dominance.Source: www.olg-frankfurt.justiz.hesse.deFull text of judgement available in German here>>.
