What is
negative contractual interest
Also known as: reliance interest, reliance damages, bid preparation costs
Negative contractual interest is a damages concept in procurement law that aims to place the harmed tenderer in the position they would have been in had the tender procedure never taken place. In practice, this means the tenderer can recover the costs of preparing and submitting a bid — such as expenses for consultants, project planning, and administration.
How does negative contractual interest work?
Under the EU Remedies Directives (89/665/EEC and 92/13/EEC), Member States must provide effective remedies, including damages, to tenderers harmed by breaches of procurement rules. A claim for negative contractual interest typically requires three conditions:
- Liability: The contracting authority must have committed a sufficiently serious breach of the procurement rules. The exact threshold varies between Member States, but must comply with the EU principles of equivalence and effectiveness.
- Causation: The tenderer must demonstrate that they would not have submitted their bid had they known about the error in the tender documents.
- Quantifiable loss: The actual costs of participating in the procedure must be documented.
How does it differ from positive contractual interest?
While negative contractual interest covers bid preparation costs, positive contractual interest (expectation damages) covers lost profit — the financial gain the tenderer would have earned had the contract been correctly awarded. Positive contractual interest requires demonstrating that the tenderer would have won the competition absent the breach. Tools like Cobrief help suppliers identify relevant public tenders early, so resources are spent on competitions with a realistic chance of success.
Who decides damages claims?
Only national courts can award damages for negative contractual interest. While procurement review bodies in some countries can assess whether the conditions for liability are met, they cannot order compensation. The CJEU's 2024 ruling in the Ingsteel case (C-547/22) further developed the EU damages framework by recognising loss of opportunity as a distinct compensable category alongside bid costs and lost profits.
Negative contractual interest serves as an important safeguard in public procurement, ensuring that tenderers are not left bearing the full cost of participating in a flawed procedure.
