The cartel authorities of the Land Hesse recently abandoned its action against six gas supply
companies represented by CMS Hasche Sigle.
At the end of June 2005 the Hesse cartel authorities initiated proceedings against a total of
12 gas suppliers on the grounds of alleged abusive practices associated with excessively high gas
prices. In August 2005 CMS Hasche Sigle submitted comprehensive legal opinions on behalf of Mainova
AG (Frankfurt), Stadtwerke Hanau GmbH, Stadtwerke Haiger, Stadtwerke Herborn GmbH, Gasversorgung
Main-Kinzig GmbH (Gelnhausen) and Gasversorgung Rüsselsheim GmbH respectively repudiating the
allegations of abuse of a market-dominant position. There followed intensive talks with the Hesse
cartel authorities which led to the cartel authorities discontinuing the proceedings.
Mainova AG was represented by Dr Harald Kahlenberg, the other five gas suppliers by Dr
Christian Haellmigk, both of the CMS Hasche Sigle office in Stuttgart.
