President Lee Appoints Kwon Chang‑young to Lead Expanded Probe of Former President Yoon
Updated (113 articles)
Lee Names Former Judge Kwon as Special Counsel President Lee Jae Myung appointed adjunct professor Kwon Chang‑young, a former district‑court judge and senior member of the Supreme Court’s Judicial Research and Training Institute, to head a new investigation into former President Yoon Suk Yeol and his wife on Feb. 5, 2026, following a recommendation from the minor Rebuilding Korea Party [1].
Probe Consolidates Three Earlier Martial‑Law Inquiries The new counsel will merge three special‑counsel investigations launched after Yoon’s brief martial‑law decree in Dec. 2024: the decree itself, allegations involving former first lady Kim Keon Hee, and the death of a young Marine, as mandated by a Democratic Party‑passed bill [1].
Mandate Targets Unexamined Election‑Interference Claims Kwon’s team is tasked with probing allegations omitted from earlier inquiries, notably alleged election‑interference and other influence‑peddling activities linked to Yoon and his wife, with a maximum investigation period of 170 days and the possibility of two extensions [1].
Parallel Legal Battles Involve Former Officials and Judiciary Former NIS director Cho Tae‑yong denied dereliction‑of‑duty charges in a Feb. 4 trial, while prosecutors sought the death penalty for Yoon on insurrection charges [2]. Opposition leader Jang Dong‑hyeok called for three separate special‑counsel probes into the ruling Democratic Party’s alleged Unification Church ties and bribery, criticizing the DP’s plan to combine investigations [3]. Former Supreme Court chief justice Yang Sung‑tae filed an appeal against a six‑month suspended sentence for power abuse on Feb. 2, highlighting the broader accountability drive across the executive, intelligence, and judicial branches [4].
