Are they required to hold the vote within the parliament building itself?
Edit: vote complete, declaration of martial law is voted down. Now what?
If the tanks politely go back where they came from, maybe parliament could consider tweaking the constitution to prevent blockading the assembly building next time.
Edit: "The South Korean military says it will maintain martial law until it is lifted by President Yoon Suk Yeol, despite the nation's parliament voting to block its enforcement". That's a bug. "the government must lift martial law" as a result of the vote, but the government is apparently the president?
