This further explains why Lee Jae-myung went on his so called hunger strike so he could be hospitalized because he likely knew many members of his own DPK political party, who are in the majority in the National Assembly, would defect to vote in favor of the motion to allow a vote on his arrest:

The National Assembly on Thursday passed a motion seeking parliamentary consent to the potential arrest of opposition leader Lee Jae-myung, a surprise result that shows a number of dissenting votes from Lee’s own Democratic Party (DP).
With the motion’s passage in a 149-136 vote, a court hearing will be held to determine whether to grant the prosecution’s request for an arrest warrant for Lee on corruption charges in connection with a land development project and a company’s illegal cash remittance to North Korea.
But it is unclear whether Lee will show up for the hearing, considering he has been on a hunger strike since Aug. 31 to protest President Yoon Suk Yeol’s handling of state affairs and was hospitalized earlier this week due to deteriorating health.
The motion needed at least 148 votes in favor to pass. Given that Lee’s DP has 168 lawmakers in the 298-member National Assembly, the result suggests that dozens of DP lawmakers voted in favor of the potential arrest of their party leader.
