The Public and Administrative Law department at Lydian is recognised for its depth of expertise and strong track record in complex matters across the full spectrum of public law, focusing on (economic) public law issues encountered by our public and private-sector clients on a daily basis. The team advises both public and private sector clients, combining technical excellence with a pragmatic, solution-oriented approach in line with our DNA.
When it comes to public procurement, our practice is at the forefront of legal service providers in this area. We assist clients throughout the procurement process, by structuring and documenting procurements (e.g. drafting tender documents or reviewing offers), by advising on procurement or bidding strategies and assisting them during negotiations, by representing award authorities or bidders before the (administrative) courts, etc. Our proficiency extends across diverse procurement sectors, encompassing transportation, energy and utilities, information and communication technology (ICT), health care, human resource management (HRM), infrastructure, financial services, and beyond.
Beyond our regulatory proficiency, we have a strong reputation as litigators in procurement, particularly in matters related to awarding and executing contracts. Our experience encompasses litigation concerning all administrative contracts before the Council of State, Belgium’s highest administrative court.
