Elektro Ljubljana d.d.

Slovenia's Competition Protection Office found that Elektro Ljubljana and four other electricity distributors acted in concert when they announced almost identical household electricity price increases on 22-23 November 2007, all effective on 1 January 2008. The authority held that the coordination restricted competition. The Supreme Court upheld the national competition-law findings on 30 June 2009, while removing only the separate EU-law finding concerning effect on trade between Member States. Elektro Ljubljana subsequently reimbursed overcharged household customers for the period from 1 January to 31 October 2008.
