In-house contracts in the European Union law

After successful implementation of public procurement procedure, a purchaser concludes public contract with a selected bidder. If, according to the European union law and Republic of Serbia domestic law, the purchaser and the bidder are considered as "affiliated" subjects, they are not obliged to apply public procurement rules and the contract they are concluding in that case is being called in-house. In order to avoid invoking an in-house contractual relation in such a situations where public procurement rules should be applied, it is important to recognize characteristics of such a contractual relation. This work presents criteria for determining in-house contract according to the European union law. The aim of the author is for domestic purchasers and bidders to better understand norms that have been taken from European union law to new Law on Public Procurement of the Republic of Serbia, so that their proper implementation can be expected.
