On 30 September 2010, the European Commission sent a reasoned opinion to Slovakia outlining a complaint that selection criteria used in a tender procedure was discriminatory. In 2007, the National Motorway Company (NMC) in Slovakia, held a public tender for a toll collection system contract (valued at around €664m). NMC rejected three out of the four tenders submitted on the grounds that they did not comply with the technical specifications. After the contract was awarded and signed in 2009, certain contract conditions were amended. It is claimed that, if those changes had been made at the beginning of the procedure, the participating companies might have submitted different tenders and the contract might have attracted more candidates. The Commission has given the Slovak authorities two months to respond to these claims.
