Limits of Administrative Discretion in Deportation Decisions: Constitutional Review in the Context of Proportionality and Non-Refoulement Principle

The Limits of Administrative Discretion in Deportation Decisions: Constitutional Review in the Context of Proportionality and the Non-Refoulement Principle

Introduction

Undoubtedly, the most controversial area of migration law and the one that most frequently intersects with human rights is the deportation process. While the administration acts with the reflex of protecting public order and security, it must establish a delicate balance between the fundamental rights and freedoms of individuals. Law No. 6458 on Foreigners and International Protection (LFIP), while granting the administration authority over deportation, has also drawn the limits of this authority. This article aims to examine how the administration's discretionary authority is limited in light of constitutional principles and international obligations, particularly within the framework of the proportionality principle and the non-refoulement principle.

1. The Administration's Discretionary Authority and Legal Basis

A deportation decision is an administrative act taken by provincial governors upon the instruction of the General Directorate of Migration or ex officio, in accordance with LFIP Article 53. The legislature has enumerated exhaustively (limitedly) in LFIP Article 54 which foreigners may be deported.

LAW ON FOREIGNERS AND INTERNATIONAL PROTECTION

Foreigners Subject to Deportation Decision

ARTICLE 54 – (1) Deportation decisions shall be made regarding the following foreigners:

• a) Those determined to require deportation under Article 59 of Law No. 5237
• b) Those who are administrators, members, or supporters of terrorist organizations or administrators, members, or supporters of criminal organizations for profit purposes
• c) Those who use false information and forged documents in procedures for entry to Turkey, visas, and residence permits
• ç) Those who have supported themselves through illegitimate means during their stay in Turkey
• d) Those who pose a threat in terms of public order, public security, or public health
• ...

When the administration determines that a foreigner falls into one of the situations enumerated in this article, it may issue a deportation decision. However, the phrase "may" or the wording of the law does not grant the administration arbitrary authority. According to the well-established case law of the Constitutional Court, administrative acts must be lawful regarding the element of cause and must be supported by material facts.

2. The Absolute Limit of Discretionary Authority: The Non-Refoulement Principle

The most definitive and insurmountable limit to the administration's discretionary authority is the non-refoulement principle, regulated in LFIP Article 55 and a jus cogens (peremptory) rule of international law. Even if a person carries the grounds for deportation under LFIP Article 54 (for example, posing a threat to public order), they cannot be deported if there is a risk of torture, capital punishment, or inhumane treatment in the country to which they would be sent.

LAW ON FOREIGNERS AND INTERNATIONAL PROTECTION

Foreigners Against Whom Deportation Decisions Shall Not Be Made

ARTICLE 55 – (1) Despite falling within Article 54, deportation decisions shall not be made regarding the following foreigners:

• a) Those for whom there are serious indications that they would be subject to capital punishment, torture, inhumane or degrading punishment or treatment in the country to which they would be deported
• b) Those for whom travel is deemed risky due to serious health problems, age, and pregnancy status
• c) Those who are undergoing treatment for life-threatening diseases and for whom treatment facilities are not available in the country to which they would be deported
• ...

The Constitutional Court evaluates the violation of this prohibition within the scope of Article 17 of the Constitution (Inviolability of the person, material and moral existence). The Court emphasizes that the state has a "positive obligation" in deportation proceedings.

CONSTITUTIONAL COURT SECOND CHAMBER

When Articles 5, 16, and 3 of the Constitution are interpreted together with international law and in particular the relevant provisions of the Geneva Convention to which Turkey is a party, it must be accepted that protecting foreigners who may be subjected to ill-treatment in the countries to which they are sent from risks to their material and moral existence falls within the state's positive obligations. Within the scope of this positive obligation, an effective means of challenge against the deportation decision must be provided so that the person to be deported can receive genuine protection from the risks they may encounter in their country.

CONSTITUTIONAL COURT SECOND CHAMBER

This case law demonstrates that the administration cannot simply say "this person committed a crime, let us deport them"; it must conduct a risk analysis (country of origin research) regarding the country to which the person would be sent.

3. Review in the Context of the Proportionality Principle

A deportation decision must comply not only with the non-refoulement principle but also with the principles of necessity in a democratic society and proportionality. In accordance with Article 13 of the Constitution, interventions in fundamental rights must be proportionate.

Proportionality review is examined under three sub-headings:

1. Suitability: Is the deportation measure suitable for achieving the purpose of protecting public order?
2. Necessity: Is it possible to achieve the same purpose through a lighter measure (for example, administrative supervision instead of deportation, an invitation to leave instead of deportation)?
3. Proportionality: Is there a fair balance between the harm the individual will suffer and the benefit the public will gain?

In particular, the foreigner's family ties in Turkey, duration of residence, and degree of integration are of critical importance in the proportionality test. The Constitutional Court defines the proportionality principle as follows:

CONSTITUTIONAL COURT SECOND CHAMBER

According to Constitutional Court decisions, the proportionality principle includes the element of suitability, which refers to the appropriateness of the measure used for limitation to realize the limitation purpose; the element of necessity, which points to the necessity of the restrictive measure for achieving the limitation purpose; and the element of proportionality, which means that the measure and purpose are not in a disproportionate measure and that the limitation does not impose an excessive obligation... To determine whether a limitation has been made in accordance with the specified criteria, the weight of the sacrifice falling on the individual in the face of the legitimate purpose underlying the measure constituting the intervention must be taken into account.

CONSTITUTIONAL COURT SECOND CHAMBER

For example, the direct deportation of a foreigner who has only committed visa violation but is married and has children in Turkey may constitute an interference with family unity and may be found disproportionate. When the administration acts in accordance with LFIP Article 54/1-e (visa violation), it cannot disregard the person's family situation.

4. The Interpretation of the Concept of Public Order and Security

The area in which the administration exercises its discretionary authority most broadly is the justification of "posing a threat in terms of public order, public security, or public health" (LFIP Article 54/1-d). However, because these concepts are vague, they are open to arbitrariness.

According to the Constitutional Court and Council of State case law:

• Abstract intelligence information alone is not sufficient for deportation.
• The element of "threat" must be concrete, current, and serious.
• Simple crimes committed in the past whose sentences have been served do not automatically constitute a current threat to public order.

CONSTITUTIONAL COURT GENERAL ASSEMBLY

Accepting the contrary would mean that administrative acts and actions based on MIT reports and evaluations would be completely removed from judicial review... Deportation decisions, being administrative acts, are subject to administrative judicial review like other administrative acts... What is important here is not to undermine and to maintain the line between arbitrariness and legality.

CONSTITUTIONAL COURT GENERAL ASSEMBLY

This decision emphasizes that even in deportation proceedings based on intelligence reports or classifications (G-87, Ç-114, etc.), judicial review must be effective, and the administration cannot create an unreviewed area by taking shelter behind the "security" justification.

5. Conclusion

Although the administration's discretionary authority in deportation decisions is a manifestation of the state's sovereignty, it is not unlimited in the face of the rule of law principle. While the non-refoulement prohibition in LFIP Article 55 constitutes an absolute barrier, the proportionality principle in Article 13 of the Constitution makes it mandatory to conduct a balancing test in each specific case.

Administrative Courts and the Constitutional Court should not view the administration's "public order" justification as an automatic approval mechanism; they must carefully examine whether the action is based on concrete facts, the risk situation in the country of origin of the person, and the proportionality of the measure. Otherwise, the fundamental rights of foreigners will face the risk of being violated in the shadow of security-oriented policies.
