By Joyce Lee SEOUL (Reuters) -South Korea's leadership crisis will play out in the Constitutional Court, which will decide the fates of President Yoon Suk Yeol and Prime Minister Han Duck-soo, both impeached and suspended from power over a short-lived martial law.

Yoon’s reaction to an uncomfortable opposition’s majority membership in the parliament is the illegal declaration of martial law. This is crude and undemocratic.
