An annulment action against a decision debarring a company from participating in tenders is, as a rule, filed before the administrative court within 60 days. Debarment decisions are expressly excluded from the 30-day expedited procedure provided for tender procedures. However, the law on which the decision is based, the publication and service information, the authority that made the decision and the date on which the act was established must each be examined separately. Filing an action does not by itself stop the debarment from being applied.
Debarment may mean more than losing only the tender in dispute. It can prevent participation in public tenders for a set period and, if the statutory conditions are met, it can also have consequences for partners and for other companies. For this reason, the work aimed at lifting the decision and the assessment of the legal position regarding upcoming tenders should be carried out together.
Why does the law on which the debarment is based matter?
The tender stage under Law No. 4734
Articles 17 and 58 of the Public Procurement Law No. 4734 regulate the sanctions linked to prohibited acts or conduct in the tender process. Distorting competition, using forged documents or guarantees, participating despite being barred, and the other acts listed in the Law each require a separate legal assessment. Not every missing document or every disqualification is, of itself, a ground for debarment from all tenders.
Article 58 of the Law provides for debarment of one to two years for the acts listed in Article 17, and of six months to one year for those who, after the tender has been awarded to them, do not conclude the contract in due form other than for force majeure. These two ranges must not be confused. Which provision the act falls under affects not only the length of the sanction but also whether it exists at all.
Performance of the contract under Law No. 4735
Articles 25 and 26 of the Public Procurement Contracts Law No. 4735 concern prohibited acts or conduct in the performance of the contract. It must be shown under which sub-paragraph each breach of contract gives rise to a sanction. The contracting authority’s claim of loss, its technical reports, its notices and the contractor’s explanations are examined together.
Under this Law, debarment of one to two years is provided for prohibited acts or conduct for which the statutory conditions are met. Termination of the contract, forfeiture of the final guarantee (kesin teminat) to the treasury and debarment may be connected; but they are not acts that will be examined before the same competent court, on the same claim and within the same period. A claim action arising from the performance of a private-law contract and an annulment action against an independent debarment act must be kept apart.
Debarment under Law No. 2886
Articles 83 and 84 of Law No. 2886 may come into play in the sale and leasing of municipal real estate. This Law provides for debarment of up to one year and for special conditions. All the provisions on periods, partnerships and sanctions in Laws No. 4734 and 4735 cannot be carried over unchanged into the scope of No. 2886. In particular, it should not be assumed that the 45-day decision period applies directly to all debarments under No. 2886.
Article 84 of No. 2886 also contains a limited provision under which, in certain circumstances, debarment is not applied in return for payment of compensation in some cases attributable to the personal fault of representatives of legal entities operating throughout Türkiye. This provision is not a route open to all bidders to “escape debarment by paying a sum”; the conditions as to person, act and period must be met together.
Who makes the decision, and against whom is the action filed?
A debarment proposal letter from the unit that conducted the tender is not the same as a debarment decision. Under Laws No. 4734 and 4735, the allocation of authority in the Law is the basis for municipalities and their affiliated units. The authority of the Ministry of Environment, Urbanization and Climate Change must be distinguished from the municipality’s duty to establish and notify the act.
For municipal companies falling under No. 4734 as well, the authority to make the decision is of separate importance. It should not be accepted that the company’s own tender official can in every case issue a debarment decision. In a dispute, the status of the body that conducted the tender, the applicable law and the final act signed by the competent authority are established.
The action is directed against the administration that issued the debarment decision. The municipality’s role in the tender file does not mean that only the municipality will be the defendant in every case. As a rule, the general rules on jurisdiction and the location of the authority that made the decision are taken into account. The fact that an individual debarment act has nationwide effect also does not, on its own, require a first-instance action before the Council of State; actions against regulatory acts are assessed separately.
Under which headings is the review of unlawfulness carried out?
Proof of the act and attribution to the right person
The administration must show which act was committed, when, by whom and with which documents. Facts such as one company’s commercial relationship with another or being at the same address should not be treated as an automatic ground for sanction independent of the specific act alleged. On the other hand, conduct aimed at affecting competition may be established by assessing the file as a whole.
For the claimant, an effective defense should be built on the records of the institution that issued the document, authority of representation, electronic transaction records, correspondence and the chronology of events. An explanation such as “I was unaware” does not produce the same legal result for every act. The elements of the act and the person’s sphere of responsibility are the basis; and the outcome of criminal proceedings and the administrative sanction are not identical in all cases.
Failure to sign the contract and a proper invitation
The questions to be answered are whether a notice in accordance with the law was given to the bidder to sign the contract, whether the necessary time was given, and whether there is a statutory waiting period that prevents the contract from being signed. If the invitation was irregular or the administration did not fulfill its own obligation, a finding that “the contract was not signed” may not be sufficient on its own.
That said, it should not be thought that the filing of a complaint application relieves the bidder of all obligations indefinitely. The nature, timing and outcome of the application, and whether a new invitation was required, should be examined. Unwillingness arising from the bidder’s own economic decision also cannot be presented as force majeure. The guarantee prepared, the documents delivered and the applications made for signing should be recorded.
Length of the debarment and proportionality
Where the Law provides a lower and an upper limit, the administration’s choice must be connected to the characteristics of the act. The seriousness of the violation, the specific case and the statutory justification are assessed. An annulment action is not a way of asking the court to take the administration’s place and select whichever new sanction it likes; the lawfulness of the act is reviewed.
How is the 45-day decision period examined?
The 45 days in Article 58 of Law No. 4734 and Article 26 of Law No. 4735 are not a period for the person concerned to bring an action. They are the period within which the administration must decide, running from the establishment of the act or conduct that calls for debarment. The 15-day period for sending the decision to the Official Gazette and the rule that it takes effect on the date of publication are separate stages.
It cannot be said that the starting date is in every case the day on which the act was committed. The determination by the relevant administration, notification to the ministry, whether a re-examination is needed and the evaluation process of the competent authority are of importance. An ordinary delay in correspondence between administrations is not the same as a genuine need for re-examination.
For this reason, rather than choosing just two dates and counting days, a chronology of events should be prepared: the act, the first determination, the inspection report, the notification, any additional investigation, the decision and the date of publication. The claimant should explain which document should be taken as the starting point and respond concretely to the administration’s later-date defense.
Consequences for company partners and other companies
Laws No. 4734 and 4735 contain special provisions on partners and on other companies in which they are partners. Being a partner in a partnership of persons and holding a majority share in a company limited by shares are not the same criterion. It must be examined to which person, and because of which partnership structure, the debarment was extended, along with the registry records for the relevant period.
Not every manager, every minority partner or every legal entity in the same group of companies is automatically regarded as debarred. On the other hand, if the statutory conditions are met, looking only at the trade name is also insufficient. The trade registry, shareholding ratios, representation documents and dates of change should be placed in the file. It should not be assumed that later changes of name or partnership automatically lift the debarment.
The filing period and the effect of an administrative application
The 60-day filing period
Unless there is a special provision for debarment acts, the general 60-day period in Article 7 of the İYUK applies. The entry into force of the decision and the start of the filing period are conceptually different. Publication in the Official Gazette, service and information on actual notice must be assessed together. Since the debarment becomes enforceable by publication, it is risky to postpone the application while waiting for separate service.
If there is a dispute as to the starting date, the period should be protected according to the earliest relevant date, including publication, and the legal explanation should be given in the petition. Being unable to find the announcement, or the relevant unit in the company learning of it late, does not create a new period in every case. The legal validity of the service and the date of electronic service are also checked separately.
Article 11 of the İYUK and an application to the Public Procurement Authority
Since debarment decisions fall outside the expedited procedure, an application under Article 11 of the İYUK made within the period can, if the conditions are met, suspend the filing period. The application must be directed to the competent higher authority, or, if there is no higher authority, to the authority that performed the act. If no reply is given within thirty days, an implied rejection arises; after the rejection, the remaining filing period runs. The period that has already elapsed is not erased so that a full 60 days begins again in every case.
The complaint review of the Public Procurement Authority (Kamu İhale Kurumu) concerning the tender process is not a mandatory preliminary application against a debarment decision. A request to correct the registry record must be distinguished from annulment of the debarment act. If the same file also involves disqualification or a guarantee measure, the route of application for those must be determined separately.
How is a stay of execution substantiated?
Under Article 27 of the İYUK, clear unlawfulness and damage that is difficult or impossible to remedy must be shown together. Allegations such as an unauthorized authority, exceeding the statutory period or an irregular invitation to contract are tied to documents. As to damage, upcoming tenders, the company’s dependence on public work, its ongoing activities and the economic effects can be made concrete.
The effect of being unable to take part in any tender because of the debarment should not be left to an abstract account. However, a claim of loss of income does not mean that the court will automatically grant interim relief. Under the general procedure, decisions on stay of execution may be objected to once, within seven days from the day following service on the authority designated by law. In this respect, a debarment action differs from a tender action subject to the expedited procedure.
Actual judicial decisions
Authority to debar in a municipal company
13th Chamber of the Council of State (Danıştay 13. Daire), 27.02.2025, E.2023/3024, K.2025/1002: The request to annul Board Decision No. 2023/DK.D-209, concerning the issuing of debarment decisions by the Ministry in tenders of municipal companies falling under No. 4734, was rejected. This is not about the merits of a debarment against a particular company, but an action concerning the Board decision that explains authority. The decision shows that the earlier approach of the company’s tender official should be questioned in a current review.
A fresh invitation to contract after a complaint
13th Chamber of the Council of State (Danıştay 13. Daire), 23.09.2025, E.2025/1802, K.2025/2788: It was held that, after a complaint and objection-complaint process begun within the period for invitation to contract, once the application is rejected the bidder must be invited again with a new 10-day period. The judicial outcome annulling a debarment applied without a fresh period being given was upheld with reasons. The decision concerns not a municipal tender but the tender of another public administration; the principle used is the requirement of a proper invitation under No. 4734.
Re-examination at the start of the forty-five days
13th Chamber of the Council of State (Danıştay 13. Daire), 06.03.2025, E.2023/2887, K.2025/1106: The date on which the debarment process became clear because of the administration’s assessment of whether the work would continue was taken as the basis. The annulment of the decision solely on the ground that 45 days had been exceeded was found incorrect, and a decision to quash was given. This decision does not mean that every ordinary piece of correspondence restarts the period, or that the debarment was definitively found lawful in all its elements.
The annulment decision, the registry and compensation
When a stay of execution or an annulment decision is obtained, how it is reflected in the records of the relevant administration and in the registry should be followed. The scope of the decision, whether another debarment exists and the special conditions of the new tender are examined separately. The expiry of the debarment period during the proceedings does not automatically remove all of the act’s past effects.
In a claim for compensation, the unlawful act, the actual damage and the causal link must be shown. The value, or the whole of the expected profit, of every tender that could not be entered is not regarded as an acquired claim. The timing of annulment and full remedy claims is assessed within the framework of Article 12 of the İYUK and the relevant procedural provisions. Under the general procedure, the period for appeal to the regional administrative court (istinaf) is 30 days, and the possibility of a further appeal depends on separate statutory conditions.
Conclusion
Building a strong debarment case depends on correctly identifying the law on which the sanction rests and the act. Authority, attribution, the 45-day administrative decision period, the 60-day filing period and the effects on partnerships must each be examined separately. If there is an urgent risk to operations, a stay of execution should be requested with concrete documents; disputes over guarantees and contracts should be pursued through their own routes of application.

Frequently Asked Questions
Is the filing period against a debarment decision 30 days?
As a rule, no; the general 60-day period applies. Debarment falls outside the expedited procedure of tender acts.
Does filing an action end the debarment status in EKAP?
No. Filing an action does not by itself stop the act from being applied. The scope of the court decision and its reflection in the registry are followed separately.
Is forty-five days the period for filing an action?
No. It is the period in Laws No. 4734 and 4735 for the administration to issue the debarment decision; its starting point is examined on the basis of the establishment of the act.
Are all company partners automatically debarred?
No. The type of company, shareholding ratios and the statutory conditions are examined. Partnership records are decisive.
Does having the guarantee decision annulled also lift the debarment?
Not always. Even if the grounds of the two acts are connected, an independent examination of the action and the period is needed.
