Public Procurement Law

Public procurement law is the body of legal rules governing how public bodies buy goods, services, and works from external suppliers. The law exists to ensure that public spending achieves value for money, that procurement procedures are fair and transparent, and that suppliers have meaningful rights against arbitrary or discriminatory decisions. Public procurement law combines European Union law, national legislation, secondary regulations, and case law from courts and review bodies, creating a comprehensive but complex framework that buyers and suppliers must navigate.

The structure of public procurement law in the EU

EU public procurement law operates at multiple levels. The Treaty on the Functioning of the European Union establishes the foundational principles of free movement of goods and services, freedom of establishment, and non-discrimination across member states. These treaty principles apply to all public procurement, including contracts below the value thresholds of the procurement directives, when there is genuine cross-border interest.

The 2014 procurement directive package establishes detailed rules for above-threshold procurement. Directive 2014/24/EU covers classical public sector procurement, Directive 2014/25/EU covers utilities procurement, and Directive 2014/23/EU covers concessions procurement. Each directive has its own scope, threshold values, and procedural rules. Member states must transpose the directives into national law within defined deadlines, although some member states historically miss these deadlines.

National implementing legislation in each member state provides the practical legal framework. Examples include the United Kingdom Procurement Act 2023 (post-Brexit), Latvia's Public Procurement Law, Germany's Gesetz gegen Wettbewerbsbeschränkungen, France's Code de la commande publique, and equivalent laws across other member states. National implementing legislation can add to the directive requirements but cannot subtract from them in ways that violate EU law.

Secondary legislation in each member state addresses specific procedural matters such as forms, electronic procurement requirements, and detailed implementation guidance. Case law from national courts, the European Court of Justice, and specialised procurement review bodies further interprets and develops the law. The combination produces a layered legal framework that practitioners need to understand at multiple levels.

Core principles of public procurement law

Several core principles run through public procurement law across the EU. The principle of equal treatment requires that all suppliers be treated identically, regardless of nationality, size, or prior relationship with the buyer. The principle of non-discrimination prohibits favouring domestic suppliers over foreign suppliers in markets that have agreed to open competition. The principle of transparency requires that procurement opportunities, decisions, and outcomes be publicly visible and that procurement criteria be published in advance and applied consistently.

The principle of proportionality requires that procurement requirements be calibrated to the value and complexity of the contract. Disproportionate requirements that exclude qualified suppliers without legitimate justification can be challenged under proportionality principles. The principle of competition requires that procurement procedures genuinely create competition rather than serving as cover for predetermined outcomes. Procurement structures that artificially exclude qualified competitors can be challenged on competition grounds.

These principles operate at a higher level than specific procedural rules. Even where the directives do not prescribe specific procedures, the underlying principles still apply. The European Court of Justice has used these principles to extend procurement obligations beyond the specific text of the directives, particularly for sub-threshold contracts with cross-border interest. Suppliers and buyers operating under public procurement law need to understand both specific rules and the principles that guide their interpretation.

Public procurement law after Brexit

Brexit changed the public procurement law landscape for the United Kingdom. The UK left the EU procurement system in 2020 and has subsequently developed its own procurement framework. The Procurement Act 2023, which came into force in 2025, replaces the previous EU-derived UK procurement regulations with a modernised UK-specific framework. The Act maintains many similar principles to EU procurement law but introduces UK-specific innovations and policy choices.

UK-EU procurement relations operate under the EU-UK Trade and Cooperation Agreement, which includes commitments on government procurement market access. The agreement allows UK suppliers to bid for EU procurements and EU suppliers to bid for UK procurements, but with reduced cross-border integration compared with EU member states. UK above-threshold notices are no longer published in the Official Journal of the European Union but on the UK Find a Tender Service.

Suppliers active across UK and EU markets now navigate two parallel above-threshold procurement regimes. The differences are meaningful but not so substantial that suppliers familiar with one system cannot adapt to the other. The fundamental principles of transparency, equal treatment, and competition apply in both jurisdictions, with detailed procedural variations that require attention but do not fundamentally change the procurement experience.

Recent developments in public procurement law

Public procurement law continues to evolve. The 2014 directive package was a substantial modernisation of the previous 2004 directives, introducing innovations such as the European Single Procurement Document, formal innovation partnerships, expanded use of electronic procurement, and stronger emphasis on quality criteria. Member states continue to develop their implementations through secondary legislation, guidance, and case law.

The European Commission has launched preliminary work on the next generation of procurement directives, although major changes are likely several years away. Areas being studied include strategic procurement for sustainability and social value, the role of artificial intelligence in procurement, the structure of frameworks and centralised purchasing, and cross-border procurement participation. Suppliers and buyers should monitor these developments to understand emerging trends.
