Objecting to an Insurance Arbitration Commission Decision? Regional Court of Appeal or Cassation, and Does Enforcement Stop?

In traffic accident, damage, or health insurance disputes, many individuals and companies apply to the Insurance Arbitration Commission before going to court. However, once the commission renders its decision, questions such as "how do I object to this decision — should I go to the regional court of appeal or directly to cassation, and does enforcement proceedings continue during the objection process?" create considerable uncertainty. In this article, we explain, in light of current case law, the legal remedy to be followed against insurance arbitration decisions and how the enforcement process operates.

Summary of the Situation

In an insurance dispute, the Insurance Arbitration Commission's Objection Arbitration Panel has rendered a high-amount compensation decision. One of the parties wishes to pursue a legal remedy against the decision, but there is uncertainty as to which court and which legal remedy (appeal to the regional court or cassation) should be pursued. At the same time, if the opposing party has already initiated enforcement proceedings on the basis of the decision, it also needs to be clarified whether the objection or the application for a legal remedy stops the enforcement proceedings.

The Legal Issue

Article 30, paragraph 12 of Insurance Law No. 5684 determines the scope of legal-remedy review against Insurance Arbitration Commission decisions according to the amount in dispute. At the heart of the matter lie two questions:

1. Following the commission decisions rendered after the regional courts of appeal became operational, should the remedy be an appeal to the regional court of appeal (istinaf), or directly to cassation (temyiz)?
2. Does an objection or an application for a legal remedy automatically stop the enforcement of the decision, or is a separate "stay of enforcement" (tehir-i icra) decision required?

What Does the Court of Cassation Say?

Not appeal to the regional court, but direct cassation

The most decisive decision on this matter is the 2020 decision on the unification of case law rendered by the General Assembly for the Unification of Case Law of the Court of Cassation. According to this decision, decisions rendered by the Insurance Arbitration Commission's Objection Arbitration Panel after 20 July 2016, the date on which the regional courts of appeal became actually operational, are subject not to appeal before the regional court of appeal, but directly to cassation. This is a critical point that is frequently confused in practice and can lead to loss of rights, because time spent under the assumption that an appeal to the regional court of appeal is the correct remedy can result in the loss of the deadline for the correct remedy (cassation).

Monetary threshold and the cassation authority

Under Article 30/12 of Insurance Law, cassation is available for decisions rendered upon objection in disputes above a certain monetary threshold. This monetary threshold is updated each year according to the revaluation rate; accordingly, the current threshold must be checked before filing an application. In addition, regardless of the amount in dispute, cassation is always available in situations such as the expiry of the arbitration period, a decision rendered outside the scope of the claim, or the arbitration panel exceeding its authority.

The Effect of the Objection on Enforcement

Under Article 30/12 of Law No. 5684, an objection filed with the commission within the statutory period against an arbitration decision automatically stops the enforcement of that arbitration decision (Court of Cassation, 8th Civil Chamber, 2017). For this stay effect to occur, it is sufficient that the objection was filed within the time limit; no security deposit is required in addition. Moreover, even if the objection application is filed after enforcement proceedings have already been initiated, the court must order the proceedings to be stopped.

Stay of Enforcement (Tehir-i İcra) at the Cassation Stage

Unlike the automatic stay effect at the objection stage, there is no automatic stay of enforcement proceedings at the cassation stage. As also emphasized in a 2025 decision of the Constitutional Court, a debtor who pursues a legal remedy against a judgment may obtain a decision for stay of enforcement from the enforcement court, provided that they deposit or provide security for the amount awarded. This is a separate process operating within the framework of Article 36 of the Enforcement and Bankruptcy Law (İİK), and it requires a separate application by the debtor.

Points to Watch

• Apply for cassation, not appeal to the regional court. For commission decisions rendered after 2016, applying for an appeal to the regional court of appeal can lead to loss of time and loss of rights; the correct remedy is cassation.
• Enforcement stops automatically at the objection stage, but not at the cassation stage. Overlooking this distinction poses a serious risk for the debtor party. If a stay of enforcement is sought at the cassation stage, a separate request for "stay of enforcement" must be made together with the deposit of security.
• Keep monetary thresholds up to date. The cassation remedy is available for disputes above the threshold set out in the law; below the threshold this remedy may be unavailable, although in exceptional circumstances such as an excess of authority, no threshold is required.
• Follow time limits meticulously. If the time limits provided for objection or cassation applications are missed, the decision may become final and become directly subject to enforcement.

Conclusion: What Should You Do?

The legal-remedy process to be pursued against Insurance Arbitration Commission decisions is a technical area requiring both an application to the correct court and proper management of enforcement proceedings. In this process:

1. Clarify the date on which the decision was rendered and whether the amount in dispute is above the current monetary threshold.
2. Remember that you should apply for cassation, not appeal to the regional court.
3. If you are at the objection stage, act with the knowledge that enforcement stops automatically; however, if enforcement proceedings have already been initiated, do not neglect to request a stay order from the court.
4. If you wish to stop enforcement at the cassation stage, deposit security and separately request a "stay of enforcement" decision from the enforcement court.

Since every stage of the legal-remedy and enforcement processes has its own specific time and form requirements, obtaining support from a legal advisor at the outset of the process is of great importance to avoid loss of rights.
