In compliance with the Directives, the PPA pushes for mandatory e-procurement. The entire communication between the contracting authority and tenderers must be in electronic form from 18 October 2018, unless the PPA expressly states the contrary. Amongst other things, bidders have to submit their bids and requests for participation electronically. However, the contract itself can be still concluded in a paper form.
During the tender procedure, the contracting authority cannot generally ask for the originals of any documents, apart from those specified in the Public Procurement Act. This means that, as a rule, the contracting authority must accept plain copies of all documents. In other words, the contracting authority cannot require bidders to submit their bids or supporting documents with e-signatures.
Before the execution of a public contract, originals or certified copies must be submitted in electronic form. If a self-declaration (or other signed document) is to be submitted as an original, it must bear a certified e-signature or have a special electronic conversion clause attached (in which case, the document would be regarded as a certified photocopy).
Interested parties need e-signatures to communicate with the Czech Competition Office in review procedures.
An e-signature is unnecessary if the parties communicate through a data box (an electronic storage site for delivering official documents and communicating with public authority bodies). Data boxes are deemed to provide certification equal to certified e-signatures.
