6 Steps to Appeal Public Procurement Decisions

6 Steps to Appeal Public Procurement Decisions. Public procurement plays a central role in the functioning of the modern state, ensuring the continuity of public services and determining the dynamics of the national economy. Constituting a significant portion of the Gross Domestic Product in Turkey, public tenders are by nature at the intersection of intense competition, complex technical specifications, and strict legal procedures. Public Procurement Law No. 4734 (PPL) adopts efficiency in the use of public resources, transparency, competition, and equal treatment as fundamental principles; for the examination of allegations regarding the violation of these principles, it envisages a unique, tiered “remedy system” that differs from general administrative judicial procedures.

This report analyzes the legal mechanisms available to candidates, tenderers, and potential tenderers who claim to have suffered a loss of rights due to unlawful acts or actions during the tender process, using a “6 Basic Steps” methodology. The aim of the report is not merely to list legislative provisions, but to deeply analyze the legal logic behind them (ratio legis), the gray areas encountered in practice, and procedural nuances shaped by the Public Procurement Board and judicial precedents. In particular, the monetary limits updated as of 2025, the digitized application processes (e-complaint), and critical details in calculating time limits constitute the main axis of the report.

The formalistic nature of procurement law, the fact that time limits are of a “forfeiture” nature, and that procedural rules take precedence over substance, necessitate that professionals operating in this field exhibit flawless process management. In this context, the report presents the process extending from the application to the administration, to the review by the Public Procurement Authority, and finally to administrative judicial review, in the light of cause-and-effect relationships, strategic foresight, and technical requirements, with academic depth and a professional tone.

Introduction: The Balance Between Freedom to Seek Rights and the Principle of Urgency in Public Procurement Law

One of the most fundamental requirements of the rule of law is that all acts and actions of the administration are open to judicial review. However, public procurements have a different perception of time compared to general administrative act theory due to practical necessities such as “non-interruption of public service” and “meeting the need on time.” In procurement law, time is the scarcest resource to be managed. Therefore, the legislator had to establish a delicate balance between the constitutional provisions regulating the freedom to seek rights and the urgency of administrative activities.

To ensure this balance, Law No. 4734 closed the path to filing a direct lawsuit and introduced a “mandatory administrative remedy path.” Accordingly, an allegation of illegality in the tender process cannot be subject to administrative jurisdiction without first being brought to the administration making the transaction and then to the Public Procurement Authority, which is the specialized institution. This tiered structure aims to resolve disputes at the administrative stage with a faster and more expert perspective, while also aiming to alleviate the workload of the courts. However, this system imposes extremely strict formal conditions and short deadlines for applicants. A one-day delay or a missing signature can change the fate of a tender worth millions of liras. This report will examine the reflections of this delicate balance in practical application step by step.

Step 1: Complaint Application to the Administration (First Degree Administrative Review)

The first and most critical step of the rights-seeking process in procurement law is the complaint application made to the administration that established the transaction alleged to be unlawful. This stage is an “internal audit” mechanism that allows the administration to review its own transaction once more, correct its error if any, and resolve the dispute before it is carried to the Authority or the judiciary. However, this application is not an ordinary use of the right to petition, but a legal process strictly bound by the capacity, time, and form conditions specified in the Law.

1.1. Capacity to Apply: Who Can Object to What?

To file a complaint, the applicant must have a legitimate and current interest in the tender process, i.e., meet the condition of “legal interest.” The legislation defines this interest through three basic statuses: “Potential Tenderers,” “Candidates,” and “Tenderers.” Each status has the right to object to different stages and different transactions of the tender process. Understanding these distinctions correctly is vital so that the application is not rejected due to “lack of capacity.”

Potential Tenderers and Objections to Documents

The concept of “potential tenderer” refers to real or legal persons operating in the field subject to the tender who have purchased the tender or pre-qualification document (or downloaded it via EKAP with an e-signature). The right of complaint for persons in this status is limited to the period before the bid submission stage is reached.

• Subject of Objection: Potential tenderers can only file a complaint against the provisions of the tender notice and the tender document (administrative specifications, technical specifications, draft contract, etc.). Allegations that a clause in the tender document prevents competition, points to a specific brand, or is contrary to legislation fall within this scope.
• Critical Constraint: A company that does not download the tender document via EKAP using an e-signature or mobile signature does not have the capacity to complain against the document. Merely “viewing” the document does not confer legal interest; the downloading process must be recorded.
• Timing: Complaints regarding documents must be made up to three business days before the tender or deadline for application. This period is an “operational time window” granted for the administration to examine the complaint and publish an addendum (amendment) if necessary.

Candidates and Tenderers

• Candidates: Those who apply for pre-qualification. They can object to transactions such as failure to obtain qualification as a result of the pre-qualification assessment or the qualification of other candidates.
• Tenderers: Those who submit bids for the tender. They have the capacity to apply regarding processes such as the submission and evaluation of bids, inquiry on abnormally low tenders, suitability of guarantees, and the final tender decision. A tenderer cannot object to the evaluation stage of a tender for which they did not submit a bid (e.g., the insufficiency of the winning company), because by not submitting a bid, they remained outside the tender and the legal interest relationship was severed.

1.2. Application Deadlines: Anatomy of Forfeiture Periods

In public procurement law, deadlines relate to public order and are taken into consideration ex officio(automatically) by courts/institutions. Missing deadlines means the termination of the freedom to seek rights specific to that tender.

General Rule: 10 Days and 5 Days Distinction

The complaint period is, as a rule, 10 days. However, the Law envisages a much faster process for certain types of tenders. In negotiated procedure tenders made according to subparagraphs (b) and (c) of Article 21 of Law No. 4734 (disasters, epidemics, sudden and unexpected events, etc.) and tenders related to framework agreements, the complaint period is 5 days.

Start and Calculation of the Period

Correct calculation of periods is a prerequisite for the application to be examined on merits.

1. Notification or Awareness: The period starts from the day following the date on which the administrative transaction was notified or the illegality was realized. For example, if the tender commission decision was notified on March 1st, the 10-day period starts on March 2nd.
2. Holidays: Weekends and public holidays are included in the period. However, if the last day of the period (10th or 5th day) falls on a holiday, the period extends until the end of working hours (17:00 or 18:00, depending on the administration’s working hours) of the first business day following the holiday.
3. Special Case in Objection to Tender Document: In complaints regarding the notice or document, the “three business days before” rule mentioned above may intersect with the general complaint period. The rule is: The complaint must be made within 10 days from the date of awareness, and in any case, it must enter the administration’s records 3 business days before the tender date. An error noticed 2 days before the tender date cannot be objected to because the 3 business day rule has closed the process.

1.3. Form and Content Requirements of the Complaint Petition

A complaint application is not an ordinary plea, but a formal administrative application. Article 8 of the Regulation on Applications regarding Tenders lists the mandatory elements to be found in the petition and the documents to be attached one by one. Failure to comply with these formal requirements does not lead to the rejection of the application (the administration may write a letter to correct deficiencies), but it leads to the prolongation of the process and loss of time.

Minimum mandatory elements in the petition:

• Name, surname, title, address, and contact information of the applicant (and their attorney, if any).
• Full name of the administration conducting the tender.
• Name of the tender and Tender Registration Number (IKN) – IKN is the ID number of the tender and prevents confusion.
• The date on which the situation subject to the application was realized (Critical for time calculation).
• Subject of the application, reasons, and the legal/technical evidence relied upon. Concrete allegations written item by item facilitate the administration’s review.

Documents to be Attached:

• Signature circular/declaration showing authority to make the application.
• Original or certified copy of the power of attorney if an attorney is used.
• Important Exception: If the tenderer has already submitted these authorization documents to the administration within the bid envelope, they do not have to submit them again attached to the complaint petition. The administration is obliged to confirm from the file in its possession.

Application Method: E-Complaint Revolution

The era of traditional physical petitions has largely ended with the integration of EKAP (Electronic Public Procurement Platform). Now, complaint applications, just like bids, can be made via EKAP using an e-signature. “E-Complaint” ensures that the date and time of entry into records are indisputable and eliminates the risk of document loss. However, except for force majeure reasons such as problems with the administration’s EKAP integration or the system being down, electronic application is essential in tenders conducted electronically.

Step 2: Administration’s Review, Decision Process, and “Implied Rejection”

Once the complaint petition enters the administration’s records, the ball is now in the administration’s court. The administration can evaluate this application as an opportunity and correct its mistake, or insist on its transaction. This stage is subject to the speed of administrative functioning and bureaucratic reflexes.

2.1. Review Period and Scope

The administration must take a reasoned decision within 10 days from the date it receives the complaint application. This period is the maximum time allowed for the administration to conduct a technical and legal review. The administration can review the application not only within the framework of the allegations in the petition but also regarding the entire transaction. However, in practice, administrations usually focus only on the complaint issues.

The administration can make three types of decisions:

1. Corrective Action: A decision where the illegality is accepted, and the process is continued by merely correcting the relevant transaction (e.g., recalculating scores, reinstating an eliminated company) without canceling the tender process.
2. Cancellation of Tender: A decision made in cases where the illegality is of a magnitude that cannot be corrected (e.g., the technical specifications being completely erroneous).
3. Rejection of Application: A decision given where the administration does not see any illegality in its transaction or the application is not suitable in terms of time/procedure.

2.2. Effect of Suspension of Tender Process

When a complaint application is made, the tender process is legally “suspended.” The administration cannot sign a contract without making a final decision regarding the complaint application, notifying this decision, and allowing the objection periods to pass. This rule is to prevent irreparable damages. Even if a contract has been signed, a timely complaint makes the execution of the contract legally controversial.

However, a decision to continue tender proceedings may be taken on the grounds of “urgency and public interest.” In this case, the administration continues the tender process while reviewing the complaint but cannot sign the contract until the final decision of the Authority. This exceptional power is usually used in tenders of vital importance (medicine procurement, school meals, etc.).

2.3. The Most Dangerous Trap of Procurement Law: Implied Rejection (Remaining Silent)

The point where applicants suffer the most loss of rights in procurement law is the misinterpretation of the “Implied Rejection” period. While silence of the administration for 30 days is considered rejection in general administrative law theory, this period and mechanism are much different and sharper in procurement law.

How Does the Mechanism Work?

The administration must respond to the complaint application within 10 days. If a decision is not notified to the applicant by the end of working hours on the 10th day, the application is deemed rejected by Law. The administration’s remaining silent is the legal equivalent of saying “No, I do not accept.”

Time Calculation and Critical Error:

The applicant cannot say, “The administration hasn’t answered yet, let me wait.” The moment the 10-day review period expires, it is assumed that the administration has given a rejection decision, and the period for applying to the Public Procurement Authority (PPA) starts ticking for the following 10 days.

• Example: You applied to the administration on February 1st. The administration’s decision period expires on February 11th (1+10 days). If no answer comes by the evening of February 11th, “Implied Rejection” has occurred as of the morning of February 12th. Your application period to the PPA starts on February 12th and ends on February 21st. If you wait for the answer and it arrives on February 25th, you will have missed the PPA application deadline.Therefore, the date of application to the administration should be noted on the calendar, and if no answer is received by the end of the 10th day, preparations for the PPA should start immediately.

Step 3: Complaint to the Public Procurement Authority (PPA) – “Appeal”

In case the administration explicitly rejects the complaint or rejects it implicitly, the authority to apply for the resolution of the dispute is the Public Procurement Authority. This stage is called “Complaint to the Authority” (often referred to as Appeal) and is the second and final step of administrative remedies. The PPA acts as an autonomous supreme board working in a quasi-judicial capacity, similar to administrative tutelage authority.

3.1. Application Period and Scope

The complaint application to the Authority must be made within 10 days (in works within the scope of 21/b-c, 5 days) from the day following the notification of the administration’s decision or the expiration of the implied rejection period.

Scope Limitation: As a rule, the complaint to the Authority is limited to the subjects in the complaint application made to the administration. The applicant cannot carry new allegations that were never mentioned to the administration and “came to mind later” directly to the Authority. However, if a “new legal situation” has emerged in the decision given by the administration upon the complaint (e.g., if the administration says “we eliminated you because your document is fake” in its response and this was not known before), this new situation can be made the subject of a complaint. Additionally, apart from the applicant’s allegations, the situation of other candidates affected by the administration’s transaction can also be examined ex officio by the Authority pursuant to the principle of equal treatment.

3.2. Mandatory E-Complaint and EKAP Procedure

With the legislative amendment dated June 20, 2021, the era of “hand-delivered petitions” has ended, and it has become mandatory to make complaint applications via EKAP using an e-signature (e-complaint). This change is revolutionary in terms of digitalization, transparency, and acceleration of the process.

Application Steps via EKAP:

1. Authorization: The person who will make the application must have the “Complaint Official” role in EKAP. The platform manager must assign this role.
2. File Creation: The relevant tender is selected from the EKAP menu, and the complaint form is opened.
3. Data Entry: The subject and reasons for the objection are entered manually into the relevant text fields (maximum character limits must be observed).
4. Date Entry: The administration’s decision date or implied rejection date is entered into the system. This date allows the system to automatically check whether the application is within the deadline.
5. Joint Ventures: In business partnerships, the pilot partner (coordinator) makes the application. Other partners do not need to sign separately, but the pilot partner’s representation authority is checked.

Step 4: Application Fee, Collateral, and Financial Obligations

To prevent abuse of the right to complain to the Authority and to prevent tenders from being arbitrarily dragged out, the Legislator has tied this application to a certain financial burden. These fees serve a deterrent function.

4.1. 2025 Application Fees and Inflationary Impact

The Public Procurement Authority updates the complaint application fees every January according to the revaluation rate. The fees determined for 2025 increase gradually indexed to the estimated cost of the tender.

The table below shows the estimated application fees valid for 2025 and the increase trend compared to 2024:

Payment Method: The application fee must be deposited into the “Corporate Collection Accounts” of the Authority at Ziraat Bank, Vakıfbank, or Halkbank. The Tender Registration Number (IKN) must be written in the EFT/Wire Transfer description. The EKAP system works integrated with the bank database; if payment is not made or made with the wrong IKN, the system does not approve the application and does not allow proceeding to the e-signature stage.

4.2. Application Collateral Mechanism

Article 53 of Law No. 4734 envisages that in addition to the application fee, an “application collateral” may be taken in complaints to the Authority. This regulation aims to prevent malicious applications intended to deadlock the tender, especially in construction works. The collateral amount can be up to four times the application fee. However, the implementation of this provision depends on the decision of the Council of Ministers (President). If the applicant is found unjust in their application, this collateral can be recorded as revenue. In current practice, which tenders require collateral should be followed from the Authority’s announcements. In cases where collateral is required, this amount is kept in a separate account independent of the Authority’s budget.

4.3. Representation by Attorney and Power of Attorney

If the application is made through an attorney, it is mandatory to scan and upload the original or certified copy of the power of attorney to the system. The power of attorney must contain the phrase “authorized to represent before the Public Procurement Authority” or a general “representation in official institutions and organizations” phrase. Additionally, attaching the bar stamp to the power of attorney should not be forgotten. In case of deficiency, the Authority may give time for completion, but this process delays the decision.

Step 5: Authority (PPA) Review: Preliminary and Substance

When the complaint application is completed and the “Send” button is pressed, the file falls digitally into the pool of the Public Procurement Authority. The review process carried out by procurement experts within the Authority is two-staged, similar to judicial procedures.

5.1. Preliminary Review (Article 16 Audit)

Before entering into the substance (content) of the file, the Authority examines whether the application meets the procedural conditions. This review, carried out in accordance with Article 16 of the Regulation on Applications regarding Tenders, is the stage where approximately 30% of applications are eliminated.

Checklist:

1. Authority’s Jurisdiction: Was the tender conducted by an administration within the scope of the PPA? Is it within the scope of exemption? (For example, some purchases of the Presidency of Defense Industries are outside the PPA).
2. Capacity to Apply: Does the applicant have the title of “tenderer,” “candidate,” or “potential tenderer”?
3. Time: Was the application made within the 10 (or 5) day period? (Most frequent reason for rejection).
4. Application Fee: Was the fee deposited in full and into the correct account?
5. Form Elements: Does the owner of the petition have the authority to represent? Is the signature valid?
6. Obligation to Apply to Administration: Was the application made directly to the Authority, or was the administrative path exhausted first?

If there is a deficiency in one of these conditions (e.g., incomplete fee, missed deadline), the Board rejects the application on procedural grounds. Only in some formal deficiencies (lack of signature declaration, etc.) may a “completion of information deficiency” period be given, but time and fee deficiencies are errors that cannot be completed.

5.2. Substance Review and Board Decisions

Files passing the preliminary review are taken into substance review. Experts examine the tender transaction file, the administration’s response, and the applicant’s allegations in detail and prepare a report. The Public Procurement Board (the Board) convenes on this report and gives its final decision.

As a result of the review, the Board can make three types of decisions:

1. Determination of Corrective Action: Cases where the illegality can be remedied without canceling the tender process. For example; “It has been determined that Tenderer A’s bid was unfairly eliminated, and it is decided that firm A be included in the evaluation and the process continues…” The administration must implement this decision.
2. Cancellation of Tender: Cases where the illegality prevents the continuation of the process. For example; situations where the technical specifications completely prevent competition, or the confidentiality of the estimated cost is violated. The tender is completely canceled, and the process starts from scratch (if desired).
3. Rejection of Complaint: The case where the administration’s transaction is found to be in accordance with the law. The applicant is found unjust.

Decision Period: The Authority must give its final decision within 20 business days (in 21/b-c tenders 10 business days) from the date the tender transaction file enters the records. However, it can be seen that these periods are sometimes exceeded due to workload.

Step 6: Judicial Review: Administrative Court and Urgent Procedure

Although Public Procurement Board decisions are “final,” they are administrative acts and are subject to judicial review pursuant to Article 125 of the Constitution. The party dissatisfied with the PPA decision (tenderer or sometimes the administration) cannot say “The party to the tender is the state, you cannot judge it”; they can carry the dispute to independent Turkish courts.

6.1. Competent Court and Jurisdiction Rule

Since the headquarters of the Public Procurement Authority is in Ankara, the competent courts for lawsuits to be filed against Authority decisions are exclusively Ankara Administrative Courts. The plaintiff (tenderer) cannot file a lawsuit in the province where their company’s headquarters is located (e.g., in Izmir). Even if they do, the court will issue a decision of “lack of jurisdiction” and send the file to Ankara. This process can take months and lead to irreparable loss of time in the tender process which needs to be urgent.

6.2. Urgent Trial Procedure (IYUK 20/A)

Tender disputes are subject to the “Urgent Trial Procedure” introduced in 2014, unlike the general administrative trial procedure (IYUK). This procedure is designed to speed up the trial:

• Period for Filing Lawsuit: It is 30 days from the day following the notification or announcement of the PPA decision. The 60-day period in general administrative lawsuits does not apply here. 30 days is a forfeiture period.
• Defense Periods: The defense period of the defendant administration (PPA) is 15 days (can be extended for another 15 days in mandatory cases). There is no right to reply to the defense; the file is perfected after a single exchange of petitions.
• Stay of Execution (YD): Filing a lawsuit does not stop the tender. The plaintiff must explicitly request a “Stay of Execution” in the petition. The court may issue a YD decision if the conditions that the transaction is clearly unlawful and that irreparable damage will occur are realized together.

6.3. Appeal Path: Council of State and Finalization

Against the decision of the Ankara Administrative Court, one cannot go to the Regional Administrative Court (Appeal). In the urgent trial procedure, the appeal stage is skipped, and an appeal application is made directly to the Council of State. The appeal period is 15 days from the notification of the court decision. The 13th Chamber of the Council of State hears tender cases. The decision to be given by the Council of State is final; the path of correction of decision is closed.

6.4. Implementation of Judicial Decision

If the court cancels the PPA decision, the Public Procurement Authority must take a new decision in accordance with the reasons of the court decision within 30 days. This new decision is called “Corrective Action Taken Upon Judicial Decision.” Administrations (institutions conducting the tender) are obliged to comply with this new decision of the PPA. Thus, the judicial decision reshapes the administrative process.

Strategic Assessment

The appeal process against public procurement decisions is a multi-disciplinary field where legal knowledge, mastery of technical procedures, and strategic time management combine. The “6 Steps” detailed throughout the report are linked in a chain; an error in one step (e.g., missing signature in the application to the administration) can render even the Council of State decision, which is the last link of the chain, ineffective.

Critical Takeaways and Recommendations:

1. Time Management is Vital: Periods run on calendar days (with exceptions), not business days. Holidays are included in the period. Waiting for the last day can be suicide due to digital infrastructure risks.
2. Cost/Benefit Analysis: The 2025 application fees (50,000 TL – 200,000 TL band) have made objections made with the logic of “let’s see if it works” economically irrational. Legal feasibility must be done before application.
3. Digital Competence: EKAP usage is now an integral part of procurement expertise. E-signature validity periods, authority definitions, and bank integrations must be constantly checked.
4. Awareness of Implied Rejection: The silence of the administration is not a positive sign, but rejection itself. Remaining passive in the face of silence means losing the right to sue.

In conclusion, the rights-seeking process in public procurements is a conflict area between the sovereign power of the state and the property and enterprise freedom of the individual/company. Success in this field depends not only on being right but on demanding this right in accordance with procedure, on time, and completely.
