Bulgaria's Supreme Administrative Court has rejected a complaint filed by Romania-based piping systems provider J. Christof E&P Services against an anti-trust body's decision to let the construction of a natural gas compressor station proceed. There are no legitimate reasons for suspension of the tender procedure called by Bulgarian gas transmission system operator Bulgartransgaz, as complaints against any decisions, actions or lack of actions by the contracting authority, with the exception of a decision for awarding a contract, can not result in suspension, the court said in its ruling published last week. The court upheld the decision of Bulgaria's Commission for Protection of Competition, dismissing J. Christof E&P Services' request for suspension. The ruling of the Supreme Administrative Court can not be appealed. According to information published by CPC, in its complaint J. Christof E&P Services objected to clarifications provided by Bulgartransgaz in relation to questions raised by potential participants in the procedure.
