The negotiated procedure was once again interrupted from 26 June because Gorenjska construction company and Kolektor CPG lodged an appeal for the third time in a row against the participation of Cengiz İnşaat accusing the company of not being suitable as a contractor. Cengiz İnşaat which has been favored by DARS from the beginning has conducted worldwide construction projects worth 24 billion USD including several hundreds of miles of railway- and roadtunnels while the complaining Slovenian construction companies can't do the build on their own and need to have partners to help them out because of their rather small size.
