Constitutional Complaint Lawyer | Understanding Your Case Before You File
Summary
A constitutional complaint (헌법소원) is a petition to the Constitutional Court of Korea asking it to strike down a statute, government order, or administrative act that infringes on a fundamental right guaranteed by the Constitution (헌법재판소법 제68조). Korea's system actually has two distinct tracks with different eligibility rules, filing deadlines, and procedural histories — filing under the wrong track, or missing the deadline, is one of the most common reasons complaints are dismissed without ever reaching the merits. This page explains both tracks, the exhaustion-of-remedies requirement, and what the review process looks like end to end.

Constitutional Complaint | Which type of constitutional complaint applies to your situation?
Not every grievance against the government qualifies for the same procedure. The Constitutional Court Act separates complaints into two tracks, and picking the wrong one can be fatal to a case regardless of its merits.
Rights-Violation Complaint
A law, order, or administrative act directly infringed your rights and no other remedy is available or effective
Legal basis
헌법재판소법 제68조 제1항
Court proceedings required first
Generally none, or none available
Filing deadline
90 days from knowledge / 1 year from occurrence
Typical target
Statute, decree, or non-adjudicable administrative act
This track is barred if a court could have reviewed the same act — the complainant must show remedies were exhausted or unavailable (헌법재판소법 제68조 제1항 단서).
Statute-Review Complaint
A court rejected your motion to refer a statute for constitutional review during your own litigation
Legal basis
헌법재판소법 제68조 제2항
Court proceedings required first
Yes — an underlying trial and a rejected motion
Filing deadline
30 days from notice of the rejection
Typical target
The statute applied in the underlying case, not the ruling itself
This track exists because ordinary courts cannot themselves declare a statute unconstitutional; only the Constitutional Court can (헌법재판소법 제41조, 제68조 제2항).
Constitutional Complaint | Who can file, and what actually qualifies
Before drafting a petition, the threshold question is whether the specific harm you experienced fits the categories the Constitutional Court is allowed to review. Many petitions fail here, before the substantive rights argument is even reached.
Standing and direct, present infringement
A complainant must show the challenged law or act directly, currently, and personally affects them — not merely a future or hypothetical harm (헌법재판소법 제68조 제1항). Complaints filed too early, before any concrete application of a rule to the complainant, are routinely dismissed for lack of ripeness.
Exhaustion of other remedies
If an administrative appeal or a lawsuit could have addressed the same grievance, that route generally must be pursued first; the rights-violation track under 헌법재판소법 제68조 제1항 is a residual remedy. The exception is where no other legal procedure exists to challenge the act at all, such as certain legislative enactments.
Court rulings themselves are usually excluded
A final judgment of an ordinary court is not, by itself, subject to a rights-violation complaint, which is one reason litigants sometimes feel the system offers no further review after losing in court. The narrow exception is where a court applied a statute that a prior Constitutional Court decision had already declared unconstitutional.
Constitutional Complaint | Deadlines that determine whether a case is even heard
Deadline compliance is checked before the merits, and there is generally no flexible extension. Missing either figure below typically ends the case at the admissibility stage.
The 90-day / 1-year rule
For a rights-violation complaint, the petition must be filed within 90 days of learning of the infringing act and within 1 year of the act occurring, whichever comes first (헌법재판소법 제69조 제1항). Both clocks run independently, so knowing about a problem late does not reset the 1-year outer limit.
The 30-day rule after a court's rejection
For a statute-review complaint, the petition must be filed within 30 days from the date the party receives notice that the trial court denied the motion to refer the statute for review (헌법재판소법 제68조 제2항, 제69조 제2항). This is a short window and typically requires the underlying case file to prepare the petition quickly.
Constitutional Complaint | What a decision can actually change
Understanding the range of possible rulings helps set realistic expectations, since an outcome other than full invalidation is common and still meaningful.
Unconstitutional, conditional unconstitutional, and non-conformity rulings
The Court can declare a provision fully unconstitutional and void, or issue an intermediate ruling such as a 'limited unconstitutionality' interpretation or a 'non-conformity with the Constitution' finding that keeps the law temporarily in force while ordering the legislature to amend it. Which outcome is sought affects how the petition should be framed from the start.
Effect on the underlying case
For a statute-review complaint, if the challenged statute is later found unconstitutional, the complainant may seek retrial of the underlying case that had been suspended pending the Constitutional Court's decision (헌법재판소법 제75조 제7항). Rights-violation complaints against administrative acts, if upheld, typically confirm that the act was void rather than automatically granting damages.
Constitutional Complaint | From initial review to final decision
1
Case intake and eligibility screening Before filing, we review whether the grievance fits the rights-violation or statute-review track, whether remedies have been exhausted, and whether the filing deadline has already passed.
2
Petition drafting The petition sets out the challenged provision or act, the specific constitutional rights implicated, and the factual basis for standing and timeliness.
3
Preliminary review (사전심사) A three-judge panel screens out petitions that are plainly inadmissible; if not dismissed at this stage, the case proceeds to the full nine-justice panel (헌법재판소법 제72조).
4
Full bench review and briefing The case proceeds to review by the full panel, which may request briefs from relevant government agencies and, in some cases, hold a public hearing.
5
Decision and, where applicable, follow-up in the underlying case The Court issues a written decision; if a statute is invalidated, further action such as a retrial motion in the original case may follow depending on the track and outcome.
Constitutional Complaint | How fees are typically structured
Case evaluation Initial review of the underlying facts, the relevant statute or administrative act, and whether the case fits an admissible track — this determines the scope of work before any fee is finalized.
Retainer fee Based on the complexity of the constitutional issue, whether an underlying trial record must be reviewed, and whether the case involves the rights-violation or statute-review track.
Court costs and filing fees Constitutional Court proceedings involve administrative costs distinct from attorney fees; these are billed separately based on actual expenses.
Success-linked fee, if agreed Some engagements include an additional fee contingent on a favorable decision, agreed in advance and calculated as a fixed amount rather than a percentage tied to guaranteed results.
※ Costs vary depending on case complexity and specific circumstances; exact fees will be provided during consultation. No specific outcome is guaranteed.
Constitutional Complaint | Self-Check Before You File
1️⃣ Track Identification
Is the source of harm a statute, a presidential decree, or an administrative act — not a court judgment itself?
Did a trial court already reject your motion to refer a statute for constitutional review?
Has any other administrative appeal or lawsuit already addressed this same issue?
Is there genuinely no other legal procedure available to challenge this act?
2️⃣ Timing
Did you learn of the infringing act within the last 90 days?
Did the act itself occur within the last year?
If this follows a court's rejection of a referral motion, was that rejection notice received within the last 30 days?
Have you already missed one of these deadlines, and if so, is any exception plausible?
3️⃣ Standing and Concreteness
Can you point to a specific instance where the law or act was applied to you personally?
Is the harm already realized, rather than a future possibility?
Do you have documentation of the administrative act or court notice triggering the harm?
4️⃣ Practical Readiness
Do you have the case number and records of any underlying administrative or court proceeding?
Are you prepared for a process that can take a year or more to reach a final decision?
Have you identified the specific constitutional right (e.g., equality, due process, property) at stake?
Frequently Asked Questions
Q. Can I file a constitutional complaint directly against a court's final judgment?
A. Generally no — a final judgment of an ordinary court is excluded from the rights-violation complaint track (헌법재판소법 제68조 제1항). The narrow exception applies where the court applied a statute that the Constitutional Court had already ruled unconstitutional before that judgment.
Q. What is the difference between the two types of constitutional complaint?
A. A rights-violation complaint (헌법재판소법 제68조 제1항) challenges a law or administrative act directly, generally without a prior lawsuit. A statute-review complaint (헌법재판소법 제68조 제2항) can only be filed after a trial court rejects your motion to refer a statute for constitutional review during ongoing litigation.
Q. How long do I have to file?
A. For a rights-violation complaint, the deadline is 90 days from when you learned of the infringing act, and no later than 1 year from when the act occurred (헌법재판소법 제69조 제1항). For a statute-review complaint, the deadline is 30 days from receiving notice of the court's rejection (헌법재판소법 제69조 제2항).
Q. Do I need to have already lost a case in court before I can file?
A. It depends on the track. A statute-review complaint requires an underlying case and a rejected referral motion. A rights-violation complaint generally requires that other remedies were exhausted or unavailable, but does not always require a prior lawsuit.
Q. What happens if the Constitutional Court rules the law unconstitutional?
A. Outcomes range from full invalidation to a 'non-conformity with the Constitution' ruling that leaves the law temporarily in effect while ordering the legislature to fix it. If your case arose under the statute-review track, you may be able to seek retrial of your underlying case (헌법재판소법 제75조 제7항).
Q. Can a company or organization file a constitutional complaint, not just an individual?
A. Yes, corporations and other organizations can be complainants for rights that are compatible with their nature, such as property rights or freedom of occupation, though certain rights tied to individual dignity may not apply to them.
Q. How long does the process usually take?
A. Timelines vary significantly by case complexity and whether a public hearing is held; cases can take from several months to well over a year from filing to final decision.
Q. Is there a preliminary screening before my case is fully reviewed?
A. Yes. A three-judge panel conducts a preliminary review and can dismiss a petition that is clearly inadmissible without it reaching the full nine-justice bench (헌법재판소법 제72조).
Q. Can I still file if I missed the 90-day or 30-day deadline?
A. These deadlines are strictly enforced and there is generally no discretionary extension, so a petition filed after the deadline is very likely to be dismissed on that basis alone regardless of the underlying merits.
Q. What kinds of government action can be challenged?
A. Statutes, presidential decrees, ministerial rules, and specific administrative acts that lack any other avenue for court review can potentially be challenged, depending on which track applies and whether standing requirements are met.
