I want to file an administrative lawsuit after the DUI license revocation administrative trial — I'm curious about the administrative lawsuit period.

If you received a license revocation disposition due to DUI, and were not relieved through administrative trial, the administrative lawsuit period is within 90 days from the day you received the original copy of the ruling.

Service of the ruling here includes not only direct receipt by the person, but also all lawful methods of service prescribed by the "Civil Procedure Act" such as supplementary service, retained service, and service by public notice.

In addition, regarding the administrative lawsuit period, if there is a justifiable reason, a revocation lawsuit can be filed even beyond the 90-day period above.

Justifiable reasons are a broad concept that includes not only reasons for which the party cannot be held responsible, but also various circumstances judged reasonable by social norms, such as personal health issues, force majeure situations, or other unavoidable reasons.

Therefore, when preparing an administrative lawsuit after going through administrative trial, you must file the lawsuit within 90 days based on the date of service of the original copy of the ruling, and if necessary, it is safer to consult with an attorney to also review whether justifiable reasons may be recognized.
