From what I could understand from the news: - the current parliament and the president are at war: the president vetoed any law the parliament passed because he doesn't like them. The parliament voted the budget and cut funding to whatever the president wished for.

- all political parties voted to have the martial law order revoked.

I don't know what the fallout of this will be, but the curent president of South Korea is toast. He went all in and lost big time.
