Following Park's remarks, the opposition Democratic Party said it would continue with impeachment procedures, warning that her speech was a scheme to avoid impeachment, Yonhap News reported.
In Asia's fourth-largest economy, impeachment is a two-step process.
The motion first requires a two-thirds majority in parliament, or at least 200 out of the 300 votes. But because the opposition coalition possesses only 171 seats in total, it must reach out to Saenuri members to gather the necessary votes.
Once the motion is passed in parliament, Park's powers would be assumed by the PM.
Next, at least six of the nine judges on the Constitutional Court, an independent body that specializes in matters of the constitution, must approve the motion within the next 180 days.
That won't be easy, Seaman warned.
"The fact that most of the judges are considered politically conservative, with two of them having been appointed by Park and the other seven installed by former President Lee Myung-bak, has fuelled speculation that they may be biased in favour of protecting the office of the president—and Park," he said.
In 2004, the Constitutional Court overturned a motion to impeach President Roh Moo-hyun after deliberating for 64 days, but the extent of political pressure in Park's case would make it difficult for the court to block impeachment this time around, he added.
"Whereas polls showed around 70 percent of respondents opposed efforts to impeach Roh, sparking public protests against the NA, recent surveys show nearly 80 percent of respondents are in favour of giving Park the boot," Seaman said.
If the court approved the motion, the PM would serve as interim president until a presidential election is held within 60 days. But if the motion was dismissed, Park would remain in office with limited powers and elections would be held in December 2017 as originally scheduled.
