(Requirements for Petitions Lodged by Highest State Organs)
A highest state organ which, in the exercise of its powers or on account of its subordinate agency's exercise of powers, considers that the applicable law is in contravention of the Constitution may lodge a petition with the Constitutional Court for a judgment declaring the impugned law unconstitutional.
A subordinate agency which, in the exercise of its powers, considers that the applicable law is in contravention of the Constitution may request its superior agency to lodge the petition referred to in the preceding Paragraph.
Paragraph 1 applies mutatis mutandis to the independent agencies which are equivalent to second-level agencies as provided for by the Basic Code Governing the Central Administrative Agencies Organizations to the extent that they independently exercise powers within their competences.

(Principle of Constitutional Petition as the Last Resort)
No petitions under the preceding Article are permissible if the relevant highest state organ can resolve the applicable law's suspected contravention of the Constitution within its competence.

(Petitions Lodged by Legislators)
A quarter or more of the incumbent Legislators who, in the exercise of their powers, believe that the relevant statutory law is in contravention of the Constitution may lodge a petition with the Constitutional Court for a judgment declaring the impugned statutory law unconstitutional.

(Contents of Pleadings Submitted by State Organs and Legislators)
Petitions under this Section shall be submitted in writing and include particulars below:
(1) in cases where the filing party is a highest state organ, the name of the petitioning organ, its representative and location; in cases where the filing parties are Legislators, the names and the domiciles or the residences thereof, and the correspondent address to which service shall be made;
(2) the name, the occupation, and the domicile or the residence of the advocate, where applicable;
(3) claims;
(4) the extent to which the impugned law contravenes the Constitution and the relevant constitutional provisions or basic rights protected under the Constitution;
(5) the grounds for the petition and the petitioner's submission; and
(6) the titles of the annexes and the number thereof.

(Declaring a Law Unconstitutional in the Holding of a Judgment)
If the Constitutional Court holds that the impugned law contravenes the Constitution, it shall declare the impugned law unconstitutional in the holding of the judgment.

(Time Limits for Voidance of Unconstitutional Laws)
The impugned law which is declared unconstitutional and is voided in a judgment shall cease to have effect from the date the judgment coming into force, unless the Constitutional Court, in the holding, declares that the impugned law is void retroactively or after a certain period of time.
In a judgment which sets a time period for the laws to lapse, the time period set for statutory laws may not exceed two years; the time period set for secondary laws may not exceed one year.

(Effect of Voidance on Pending Cases before Other Courts)
Where the applicable laws are declared void immediately or retroactively, all the cases pending in any court are to be adjudicated in accordance with the ratio decidendi of the judgment of the Constitutional Court.
The legal effect of final court decisions, except otherwise statutorily provided, will not be affected by the judgment of the Constitutional Court that declared the applicable law void immediately.
The final court decisions where the applicable laws are thereby voided retroactively may be redressed pursuant to legal procedures or the ratio decidendi of the judgment of the Constitutional Court. Where such final court decisions are criminal, the Attorney General shall file an extraordinary appeal.

(Effect of Voidance with Time Limits on Pending Cases before Other Courts)
In a judgment where a time period is set for the impugned statutory law to lapse, all courts shall, before the set time period expires, continue to apply the impugned statutory law to adjudicate cases, except otherwise declared in the holding of the said judgment. Notwithstanding, after balancing the protection of human rights and public interest, and out of necessity, the court may, on its own motion or the party's, suspend the proceedings by an order, and, upon the amendment of the impugned statutory law, resume the proceedings and adjudicate such cases in accordance with the amended law.
An order denying the motion under the preceding Paragraph is subject to interlocutory appeals.
