A South Korean appeals court is set to deliver a ruling Wednesday on former President Yoon Suk-yeol's case involving charges including obstructing investigators from executing an arrest warrant against him, Yonhap News Agency reported.

It will mark the first appellate ruling among cases related to Yoon's emergency martial law declaration on Dec. 3, 2024.

Yoon was accused of mobilizing presidential security officials in January 2025 to block the Corruption Investigation Office for High-ranking Officials (CIO) during its attempt to detain him.

He was also charged with abuse of power for allegedly violating the rights of nine Cabinet members to deliberate on the martial law declaration by convening only some Cabinet members to make it appear that a Cabinet meeting had been held.

Additional charges included allegedly drafting a false official document to prepare a fabricated martial law proclamation after martial law was lifted and later discarding it.

A district court sentenced Yoon to five years in prison in January after finding him guilty of key charges. Both the special counsel and Yoon appealed the ruling. The special counsel demanded a 10-year prison term at the final hearing of the appeals trial earlier this month.

Yoon is also set to attend the first formal hearing on Wednesday in another case involving allegations that he exerted pressure on a probe into the death of a young Marine in 2023.

In a separate case on Feb. 19, he was sentenced to life imprisonment in the first-instance ruling for leading an insurrection over his martial law declaration.
