Katarzyna Kuźma, Michał Wojciechowski and Weronika Jędrzejewska from the public procurement team in the Infrastructure and Energy Practice successfully represented the consortium of China Civil Engineering Construction Corporation and China Railway 19th Bureau Group before the National Appeal Chamber (NAC) in a dispute over the largest investment in the railway sector in recent years, i.e. a 71 kilometre section of the E75 railway line between Czyżew and Białystok. This investment is part of the Rail Baltica international route.

The NAC upheld the arguments of the China Civil Engineering Construction Corporation and China Railway 19th Bureau Group consortium regarding the need for the winning consortium (Przedsiębiorstwo Usług Technicznych Intercor and two entities belonging to the PowerChina group) to supplement the information on their experience needed to meet the conditions for participating in the tender.

Thus the NAC ordered PKP PLK to invalidate the selection of the Intercor consortium's bid and to re-examine and re-evaluation its bid and request it to provide the missing information.
