Areas of practice

Stefan Mager's consulting is solution-oriented, entrepreneurial and future-oriented. He advises large-volume construction contracts, complex IT projects as well as on the EU-wide and national award of contracts for the procurement of goods and services. Together with his team, he advises on the structuring of tendering procedures and provides full-service support (from the announcement, to the award of the contract and the documentation) from one source. In particular, he specialises in advising public utility companies and public safety authorities and organisations. He helps bidders in review proceedings enforce procedures to ensure they are error-free from a legal perspective. With regard to EU state aid law, Stefan Mager has many years' experience dealing with issues relating to “services of general economic interest” (SGEI) and the General Block Exemption Regulation (GBER). In this context, he regularly heads up Luther's team of advisors in large urban development projects.


Stefan Mager became an antitrust lawyer at the age of 26. He completed his doctorate under the supervision of Prof. Martin Burgi (now Ludwig Maximilian University in Munich, Germany) on the interface subject of "public procurement law and the law regarding fees and charges". Before joining Luther in 2020, he was the head of the antitrust, public procurement and state aid law department at a German top 50 law firm, where he was also a co-managing partner. In this function, he was at the same time the managing director of a German data protection and consulting company. The Bar Association in Hamm (Germany) appointed him as chairman of the expert committee for public procurement law. Stefan Mager is, amongst other things, the author of commentaries on public procurement law in “Großkommentar Vergaberecht” published by the Beck publishing house and is also a sought-after speaker on current topics.
