What is an
exclusion ground
Also known as: ground for exclusion
An exclusion ground is a legal basis that allows or requires a contracting authority to exclude a supplier or reject a tender in a public procurement procedure. While rejection refers to the act itself, exclusion grounds are the underlying reasons that trigger it — from criminal convictions to material non-compliance.
How do exclusion grounds work?
EU Directive 2014/24/EU establishes the framework for exclusion grounds in Article 57, distinguishing between two main categories. Mandatory exclusion grounds require the contracting authority to exclude a supplier. These cover convictions for serious criminal offences such as corruption, fraud, money laundering, terrorist financing, and human trafficking. Mandatory exclusion also applies when a supplier has failed to pay taxes or social security contributions as established by a judicial or administrative decision.
Discretionary exclusion grounds give the contracting authority the right, but not the obligation, to exclude. Examples include insolvency, grave professional misconduct, agreements aimed at distorting competition, significant deficiencies in prior public contracts, and serious misrepresentation. The authority must assess whether exclusion is proportionate in each case.
Beyond supplier-related grounds, there are also grounds for rejecting the tender itself — for instance, when it contains material deviations from the tender documents or substantial reservations that alter the competitive balance between tenderers.
Self-cleaning and documentation
A supplier affected by an exclusion ground may demonstrate remedial measures under the self-cleaning mechanism (Article 57(6)). This includes paying compensation, cooperating with authorities, and implementing organisational changes to prevent recurrence. If the measures are deemed sufficient, the authority cannot exclude the supplier. The maximum exclusion period is five years for mandatory grounds and three years for discretionary grounds.
The ESPD serves as preliminary self-declaration confirming that no exclusion grounds apply to the supplier. Tools like Cobrief help suppliers stay informed about tender requirements, reducing the risk of exclusion due to non-compliance.
Exclusion grounds are a cornerstone of EU procurement law, ensuring only reliable suppliers and compliant bids participate in public tender procedures while giving suppliers a path to rehabilitation through self-cleaning.
