This article analyses the application of competition rules to abnormally low tenders. The purpose is to determine whether – and under which circumstances – abnormally low tenders may constitute violations of Articles 101 and 102 TFEU, as well as how contracting authorities may or should proceed in case of potential infringements of competition law. It is concluded that abnormally low tenders may indeed violate EU competition law, which can lead to distortions of competition in public procurement markets in the short and/or long run, resulting in a decrease of social welfare. The parallel existences of the two sets of rules that regulate low prices – but which do not entirely coincide – do not seem to facilitate enforcement of competition law violations, which is crucial to obtaining efficient public procurement. Some proposals for a more competition-oriented approach to abnormally low tenders are provided.
