Abstract
The material presented in the article contains a description of the evidence proceedings before the National Appeal Chamber, including the presentation of means of electronic evidence in public procurement proceedings. The principle of direct access to evidence and the need to adapt the appeal procedure to progress required by the change introduced in communications between the contracting authority and contractors means that the parties have broader access to evidence using IT tools. The further development of digitisation procedures may make proceedings more efficient, but on the other hand there is a risk of hindrances that will slow down such proceedings. Such aspects may be indicated from the previous experiences described in the material, although the final conclusion leads to the thesis that, in the era of developments in communication techniques, the appeal procedure, and the evidentiary proceedings at its heart, should also follow this direction.
