Public Security

In public security cases — National Security Act, Assembly and Demonstration Act, Anti-Terrorism Act —
we defend the constitutional rights of those under investigation.

01

Overview

Public security cases encompass criminal matters relating to national security and public order — including violations of the National Security Act, the Assembly and Demonstration Act, the Military Criminal Act, and the Anti-Terrorism Act. These cases demand sophisticated legal analysis to strike the appropriate balance between constitutional fundamental rights and national security.

PYEONG AN's public security cases are handled exclusively by attorneys with hands-on experience in the Prosecutors' Office Public Security Division, the National Intelligence Service, and the military prosecution service. We accurately assess the political context of each case while formulating the optimal defense strategy from a purely legal standpoint.
