The issue of changes in the obligations resulting from contracts on public procurement is constantly present in legal literature and judicature alike. It refers to both modifications related to the contents of a contract, and changes in the parties of a contract. The latter have been discussed in this article. The importance of the issue is unquestionable because, on the one hand, when contracts are realised it frequently happens that there is either an economical or organisational need to introduce certain modifications, but on the other hand, public procurement contracts are rigorously regulated as for legally binding modes of selecting contractors. Hence a question arises whether and on what conditions modifications as for the contracting parties in the area of public procurement can be regarded as permitted.
