(Petitions for Constitutional Complaints)
After exhaustion of all ordinary judicial remedies, any person who believes that a final court decision that ruled against her or him, or the applicable law therein, unlawfully infringes upon her or his constitutional rights and contravenes the Constitution, may lodge a petition with the Constitutional Court for a judgment declaring either the said decision, or both the said decision and the applicable law therein unconstitutional.
Petitions under the preceding Paragraph must be lodged within the peremptory period of six months starting on the next day of the date when the final court decisions were served.

(Contents of Pleadings of Constitutional Complaints)
Petitions under this Section shall be submitted in writing and include particulars below:
(1) the name, the identification document number, and the domicile or the residence of the petitioner, and the correspondent address to which service shall be made; in the case that the petitioner is a legal person or an unincorporated association, its name and location;
(2) the name, the identification document number, and the domicile or the residence of the statutory agent, the representative or the administrator, where applicable;
(3) the name, the occupation, and the domicile or the residence of the advocate, where applicable;
(4) claims;
(5) the extent to which the legal provision applied in a final court decision or the decision itself contravenes the Constitution and the relevant constitutional provisions or basic rights protected under the Constitution;
(6) the grounds for the petition and the petitioner's submission; and
(7) the relevant final court decision and the evidence which proves the observance of the peremptory period; and
(8) the titles of the annexes and the number thereof.

(Admissibility of Constitutional Complaints)
Petitions under this Section are admissible insofar as they concern principles of constitutional significance or it is necessary to satisfy the petitioners' basic rights protected under the Constitution.
The Chamber may dismiss a petition by a unanimous order for which reasons must be given; otherwise, the admissibility of the petition shall be decided by the Constitutional Court.
If three or more Justices, within 15 days after the preceding unanimous dismissal order has been made, consider that the petition is admissible, the Constitutional Court shall decide on its admissibility. The dismissal order shall otherwise be published and served on the petitioner promptly.

(Declaring a Final Court Decision or a Law Unconstitutional in the Holding of a Judgment)
If the Constitutional Court finds that the petition is well grounded, it shall declare in the holding of the judgment that the impugned final court decision is unconstitutional and thus vacated, and the matter is remanded to the competent court. If the Constitutional Court finds that the legal provision applied in such a final court decision contravenes the Constitution, it shall further declare the impugned legal provision unconstitutional.
Articles 51 and 52 shall apply mutatis mutandis to the judgments under the preceding Paragraph.

(Application mutatis mutandis of Voidance Provision)
Except otherwise provided in this Act, Articles 53 shall apply mutatis mutandis to cases where laws are voided immediately or retroactively by the Constitutional Court in the judgments under this Section.

(Application mutatis mutandis of Voidance with Time Limits Provision)
In a judgment where a time period is set for the impugned legal provision to lapse, the competent court to which the underlying case of the relevant final court decision is remanded shall decide in accordance with the ratio decidendi of the judgment of the Constitutional Court by which the impugned legal provision is declared unconstitutional, notwithstanding the time period set for the lapse of the legal provision declared unconstitutional, unless the holding of the judgment otherwise decides.
Where a legal provision is set to lapse within a time period under the preceding Paragraph, Article 54 shall apply mutatis mutandis to cases other than the relevant underlying case that are pending before each court.
