Defense strategy for exclusion

Two types of exclusion — two different paths

Before deciding whether to appeal, you need to understand why you were excluded. We distinguish two main categories because they lead to entirely different strategies.

Formal exclusion grounds are procedural: a missing document, an expired bank guarantee, an uncertified signature, a mismatch with a template, an incorrectly completed ESPD (European Single Procurement Document). These grounds share one trait — they are independent of your actual capacity and experience. A qualified bidder can be excluded over a line in a document, not over substance.

Substantive grounds concern your actual profile: you don't meet the turnover threshold, you lack the required experience for a specific type of activity, your key expert doesn't satisfy the qualification requirements. Here the exclusion reflects a genuine mismatch with the conditions.

The distinction is critical because the realistic chances of success before the CPC and SAC differ enormously between the two categories. Formal grounds — especially when the requirement itself is vaguely worded or disproportionate — historically show higher rates of being upheld on appeal. Substantive grounds succeed less often, unless the requirement itself is unlawful.

How the appeal procedure works

A complaint against a decision to select a contractor or to terminate a procedure must be filed with the CPC within 10 days of the act's publication in the Public Procurement Register. These deadlines are preclusive — once they expire, the right to appeal is lost with no exceptions. That is precisely why the assessment of grounds must be done quickly.

The CPC examines the complaint on the documents and, where necessary, holds an oral hearing. The CPC's decision may uphold the contracting authority's act, annul it in full or in part, or remand the file for a fresh decision. The statutory time limit for the CPC to rule varies in practice depending on caseload.

Against a CPC decision, a cassation appeal to the SAC may be filed within 14 days of service. The SAC acts as a cassation court and reviews primarily legality rather than re-weighing the facts. The SAC's ruling is final.

An important practical note: filing a complaint with the CPC generally suspends execution of the challenged act — the so-called suspensive effect. This means the contract cannot be signed until the CPC rules, which is a significant protective measure for the appellant.

The role of precedents: 205,000+ decisions as a compass

The CPC and the SAC do not operate in a vacuum — their decisions form a body of practice that every experienced market participant uses for orientation. But access to that practice has historically been difficult: decisions are public yet scattered, hard to search, and without systematic categorisation by exclusion grounds.

Slavov Capital holds a database of over 205,000 decisions, protocols and reports linked to 84,532 tracked public tenders. This base enables something that manual research cannot achieve in a reasonable time: systematic retrieval of comparable cases by key parameters — type of requirement, sector, procedure type, wording of the exclusion ground.

The result of precedent analysis is not legal advice — it is an informed view of the historical picture. If over recent years the CPC has upheld similar complaints in a significant number of cases involving a particular type of formal error, that is a strong input for a decision to appeal. If the historical success rate for substantive grounds is low, the picture is different.

We emphasise: any specific percentages are illustrative samples reflecting the general order of magnitude in our database. They are not official CPC or SAC statistics. The real assessment is conducted for the specific ground, sector and wording of the condition.

Risk analysis: is the appeal worth it

Appealing is not free and not risk-free. Beyond the costs of legal representation and administrative fees, you must account for the opportunity cost — time and resources committed to an appeal are resources diverted from the next procedure.

Our approach to risk analysis combines three dimensions. First — legal solidity: how strong is the appeal ground in light of the regulatory framework and established practice? Second — precedent profile: what does the historical pattern for comparable cases in our database look like? Third — economic rationale: what is the contract value, what is the fee, what is the expected timeline, and what do you gain on success relative to the opportunity cost of your time?

When all three dimensions favour the appeal — the ground is formal, the precedents are favourable, and the contract value justifies the cost — we recommend engaging a lawyer with a complete file. When the picture is mixed or unfavourable, the honest conclusion is "don't appeal" — and we point to the next suitable procedure instead.

To be clear: Slavov Capital provides analytical support — assessment of grounds, precedent analysis and a strategic cost/benefit review. For legal representation before the CPC and SAC, we recommend engaging a lawyer specialising in public procurement. The two roles are complementary, not mutually exclusive.

Which requirements are more vulnerable on appeal

CPC and SAC practice identifies several types of conditions that have historically been more likely to be annulled on appeal. Knowing them helps not only when appealing but also when assessing procedures before bidding — if conditions look unlawful, the risk of a challenge cuts both ways.

Among the more vulnerable categories: overly specific experience requirements tied to an exact value or exact number of completed contracts without objective justification; requirements for certificates or registrations disproportionate to the subject matter; vaguely worded evaluation criteria permitting subjective interpretation; and formal rejections based on a strained reading of a template or ESPD where the requirement itself was clear.

Conversely, requirements set on a clear legal basis, with an objective value justification and consistent application in the sector, are difficult to challenge. Precedent analysis helps you judge which side of this line you are on.

• Overly specific experience requirements without objective justification.
• Disproportionate financial thresholds out of proportion to the contract subject.
• Vague or subjective criteria for evaluating technical proposals.
• Formal rejections based on a strained reading of a template or ESPD.
• Requirements that artificially restrict competition.

The steps of the defense strategy

A defense strategy does not begin at the moment of exclusion — it is prepared, as far as possible, before the bid is submitted. When you spot a potentially unlawful requirement in the documentation, you have two options: challenge it pre-emptively (before the submission deadline) or bid and defend yourself after a potential exclusion. Both approaches have advantages and disadvantages, and the choice depends on the specific situation.

Once exclusion has occurred, the strategy follows a clear sequence: immediate assessment of the ground (within hours, not days), analysis of precedents from comparable cases, consideration of economic rationale, and — if the decision is positive — engaging a lawyer to draft the complaint.

Within the scope of the service we deliver a structured analytical file: assessment of the lawfulness of the exclusion ground, a summary of comparable precedents from our database with their outcomes, an indicative probability assessment (clearly labelled as illustrative), and a list of arguments that can form the basis of the complaint. The lawyer receives a ready file rather than starting from scratch.

What you get

The deliverable is a structured analytical file intended for you and for the lawyer you may engage. It contains everything needed for an informed decision within the minimum possible time.

• Classification of the exclusion ground — formal or substantive.
• Lawfulness assessment with references to ZOP, PPZOP and applicable EU directives.
• A summary of up to 10 comparable precedents from the database with their outcomes.
• An indicative probability assessment (illustrative, not legal advice).
• Cost/benefit analysis: fee, expected timeline, contract value.
• A list of arguments for the complaint, ready for use by a lawyer.
• Recommendation: appeal, no appeal, or pre-emptive challenge in the next procedure.
