An applicant challenging a security-based restriction faces an obvious difficulty: they are asked to disprove an allegation they have never been shown. The answer Turkish administrative law gives is that this is the wrong way round. The administration acted; the administration must be able to show why. This article is about that principle, how it operates in practice, and what a well-run case actually does with it.
The principle
Administrative acts must rest on lawful and factual grounds. An act whose stated basis cannot be demonstrated is defective, and the administrative courts annul acts on that ground.
This is not specific to immigration. It is a general feature of administrative law: authority is conferred to be exercised on a proper basis, and judicial review exists to test whether it was.
Applied to restriction codes, it means that where the administration records that a person constitutes a security threat, it must be able to show the court a substantiated foundation for that conclusion. Settled administrative case law has annulled decisions where the administration produced nothing beyond an unexplained assertion.
Why this matters more here than elsewhere
In most administrative disputes both sides can see the material. A permit was refused because insurance was inadequate; the policy is in the file; the argument is about its adequacy.
Security assessments are different. The applicant is told a code exists and, frequently, nothing more. They cannot address the substance because they do not know it. If the burden fell on them to disprove it, the code would be unchallengeable by design.
The principle prevents that. The applicant does not have to prove a negative; the administration has to produce a positive.
How it works in the litigation
The mechanism is the court's power to require the administration to produce the file underlying its decision.
That production is the pivot of the case. One of three things follows:
- Substantiated material appears. The applicant can then address it — sometimes successfully, where it is mistaken, outdated or concerns another person.
- Nothing appears beyond a conclusion. This is where the principle does its work: an assessment without a demonstrated basis is exposed.
- Material appears that is withheld from the applicant on security grounds. This is the hardest scenario, and the argument then concerns whether the applicant can meaningfully challenge a decision whose basis they cannot see — a question engaging the right to an effective remedy.
Preparing a case means anticipating all three rather than only the second.
What the applicant should still put forward
The burden being on the administration does not mean the applicant files nothing. A petition consisting only of "let them prove it" is weaker than one that also builds a positive case.
- A clean record, evidenced: criminal record certificates from Türkiye and from countries of residence.
- Ties to Türkiye: family, children in school, property, employment, tax and social security records, length of residence.
- A coherent account of the applicant's history — travel, employment, associations — that leaves no unexplained gaps for an assessment to occupy.
- Documentation resolving any underlying matter: an acquittal, a discontinued prosecution, a withdrawn Interpol notice.
- Evidence distinguishing the applicant from another person, where mistaken identity is suspected — passport histories, identity numbers, dates and places of birth.
- Family life evidence, engaging the constitutional protection and Article 8 of the European Convention on Human Rights.
The purpose is to present a person about whom the assessment makes no sense, so that the absence of material on the other side is conspicuous.
Mistaken identity
This deserves separate treatment because it is more common than expected and, when established, decisive.
Transliteration from other alphabets produces names that collide. A common surname, a shared date of birth, a similar rendering — and a person carries someone else's record.
Where this is suspected, the case is built on precise identifiers: passport numbers across time, identity numbers, place of birth, parents' names, travel history establishing that the applicant was elsewhere. The argument is factual rather than legal, and it is winnable.
Proportionality
A second line that operates alongside the first. Even where some basis exists, the measure must bear a reasonable relationship to it.
An indefinite restriction on a person with a Turkish spouse and children in school, resting on an association rather than conduct, invites that argument. So does a multi-year ban following a technical breach.
Proportionality is not a substitute for the primary argument. It is what remains when the administration produces something, and it is frequently where these cases are actually decided.
Managing expectations
Two honest observations.
No lawyer can predict the outcome before seeing what the administration produces, because that is the variable. Anyone offering a percentage at the outset is guessing.
And a favourable judgment removes the decision, not the underlying assessment. Where the administration retakes the decision on a properly demonstrated basis, that is a new act. Where it simply repeats the same conclusion without a basis, the repetition is itself challengeable.
Practical steps
- Establish what is recorded before anything else.
- Identify the act and its deadline — sixty days for most decisions, seven for a removal decision.
- File within the period, with a stay of execution request where implementation would cause irreparable harm.
- Request production of the file and be ready to respond to whatever appears.
- Build the positive case in parallel.
- Keep the constitutional dimension in view from the start, so that it is available at the end.
Frequently asked questions
Do I have to prove I am not a threat? No. The administration must demonstrate a basis for its assessment.
Will I see the material? Sometimes. Where it is withheld on security grounds, the argument shifts to the effectiveness of the remedy.
What if there is genuinely nothing behind the code? That is the strongest case, and it is what production of the file reveals.
Can mistaken identity be established? Yes, with precise identifiers. It is more common than people expect.
How long does it take? Months at first instance, plus appeal.
Can I run the case from abroad? Yes, under a power of attorney; the procedure is written.
What if I lose? Appeal where available, and consider the constitutional route where fundamental rights are engaged.
The question the case turns on
Every security code case comes down to one moment: what the administration produces when the court asks. Everything before that is preparation, and everything after is argument about what appeared.
