Mandatory Exclusion Grounds

Mandatory exclusion grounds represent the hardest line in European public procurement compliance. Unlike discretionary exclusion grounds, which leave room for the contracting authority to weigh proportionality, mandatory grounds trigger automatic exclusion the moment a relevant conviction is established. No amount of capability, competitive pricing, or track record overrides them.

What are Mandatory Exclusion Grounds?

Article 57(1) of Directive 2014/24/EU lists the offences that give rise to mandatory exclusion. A supplier must be excluded from participation if the contracting authority has established by means of a final judgment that the supplier or any of its directors, partners, or persons with powers of representation have been convicted of any of the following:

Participation in a criminal organisation, as defined in Article 2 of Council Framework Decision 2008/841/JHA.

Corruption, including active and passive bribery of national or foreign public officials, as defined in relevant EU instruments.

Fraud affecting the EU's financial interests, as defined in the Convention on the Protection of the European Communities' Financial Interests.

Terrorist offences or offences linked to terrorist activities, as defined in EU Framework Decisions 2002/475/JHA and 2008/919/JHA.

Money laundering or terrorist financing, as defined in Directive 2005/60/EC.

Child labour and other forms of trafficking in human beings, as defined in Directive 2011/36/EU.

The exclusion applies to convictions of the economic operator itself, its directors, partners, or any person with powers of representation, management, or supervisory capacity. A supplier cannot escape exclusion simply by replacing a convicted individual after the fact, unless genuine self-cleaning is accepted.

In the UK, the Procurement Act 2023 preserves these categories as mandatory grounds and adds some offences that were previously discretionary under the 2015 Regulations, such as certain environmental offences and repeated failures in prior public contracts.

Why Mandatory Exclusion Grounds Matter for Bidders

Because mandatory exclusion carries no proportionality escape (other than self-cleaning), compliance programmes and regular checks against conviction registers are essential for any organisation active in European public tendering. The key risk areas are:

Group companies. If a parent, subsidiary, or affiliated entity has a relevant conviction, the authority may investigate whether that conviction is attributable to the bidding entity. Group structures do not automatically insulate an operating company.

Consortia. All consortium members are subject to mandatory exclusion checks. A conviction in one member firm can disqualify the entire consortium.

Duration. Mandatory exclusion lasts a maximum of five years from the date of final conviction. After that period, the supplier regains eligibility, though some national implementations set shorter windows.

Example

A German engineering firm is bidding for a European Infrastructure Fund construction contract. A regulatory review reveals that the firm's former CFO received a final conviction for fraud against EU financial interests three years ago. The CFO resigned on conviction. The firm has since introduced a full compliance and anti-fraud programme. The contracting authority reviews the mandatory exclusion and considers whether the self-cleaning evidence submitted is sufficient to allow the firm to continue in the competition.

Frequently Asked Questions

Does a pending criminal investigation trigger mandatory exclusion?

No. Mandatory exclusion requires a final judgment of conviction. A pending investigation or a conviction under appeal does not automatically trigger mandatory exclusion under EU law, though some authorities may treat it as a discretionary exclusion ground if it constitutes serious professional misconduct.

Can a conviction against a former director still exclude a company?

Yes. If the conviction was received while the individual held a position of representation, management, or supervision in the company, the conviction may be attributed to the company even after the individual's departure, unless self-cleaning measures are accepted.

How does a supplier prove it has no relevant convictions?

At the bid stage, self-certification via the ESPD is normally sufficient. The winning bidder is then required to provide extracts from criminal records or equivalent certificates. Where a national criminal records system does not cover a particular offence, a sworn declaration may be accepted as a substitute.
