Calls are growing for the Constitutional Court's swift decision on President Yoon Suk Yeol's impeachment, as its protracted deliberation is causing public fatigue with continuous political confrontations and months of rallies either supporting or opposing the removal of the president.

As public expectations for a verdict have risen and been dashed every week since the final hearing on Feb. 25, this situation is even leading to criticism toward the court for causing further political turmoil and national confusion.

Rep. Lee Jae-myung, leader of the main opposition Democratic Party of Korea (DPK), requested the court to swiftly rule on Yoon's impeachment over his Dec. 3 martial law declaration.

"There must be a reason why the court has not made a ruling since the final hearing, but the public, who are not aware of internal circumstances, cannot help but feel anxious and suspicious," Lee wrote on Facebook, Sunday.

"I ask the Constitutional Court to deliver a wise decision as soon as possible for the benefit of all the people."

Rep. Na Kyung-won of the ruling People Power Party (PPP) also urged the court to make its ruling in the upcoming week.

"The court rushed when it held hearings, so why isn't it rushing now when it has to make the verdict?" she said on her Facebook.

"The court should make a swift decision in order for the nation to end national division, properly respond to disasters like wildfires and overcome economic, diplomatic and trade crises."

Minor opposition Rebuilding Korea Party is even seeking a group litigation from "citizens who have suffered mental distress from the court's prolonged deliberation" to get compensation from the court.

"The verdict to impeach Yoon has been delayed without any reason," Kim Sun-min, acting leader of the party, said in a press briefing at the National Assembly in Seoul.

Kim said citizens holding rallies to support or oppose the impeachment have been suffering "group trauma."

"If the court does not make a ruling by April 4, we'll encourage citizens to participate in the group litigation [to seek compensation from justices]."

Along with the protracted ruling, the issue of appointment to the nine-member bench, which is currently one member short, has been controversial as its composition could affect Yoon's trial.

The DPK urged acting President and Prime Minister Han Duck-soo to swiftly appoint opposition-recommended candidate Ma Eun-hyuk as the ninth justice. They believe appointing one more liberal judge to the court could increase the prospect of ousting Yoon and holding a snap presidential election.

On Sunday, the DPK accused Han of betraying the public's trust by neglecting to carry out his duties.

In late December, the DPK-led Assembly passed an impeachment motion against Han for multiple grounds, one of which was his refusal to appoint two justice candidates. After Han's suspension, then-acting President Choi Sang-mok appointed two of them, while not appointing Ma. Han was reinstated following the Constitutional Court decision last week.

"If Prime Minister Han refuses to fulfill his constitutional duty by April 1, the DPK will make a major decision," DPK floor leader Rep. Park Chan-dae said.

While Park did not specify what action the party will take, a group of first-term lawmakers of the DPK on Friday threatened to impeach Han again unless he quickly appoints Ma. They also threatened to impeach any Cabinet member who becomes acting president next if they don't appoint Ma.

The PPP criticized the DPK of attempting to disband the Cabinet and paralyze the government.

"The DPK declares that it would make a ‘major decision' if Ma is not appointed by April 1. It is a declaration of war against the people. It is a dangerous attempt to overthrow the state and instigation of rebellion," Rep. Shin Dong-wook, chief spokesperson of the PPP, said.

A day earlier, PPP floor leader Rep. Kweon Seong-dong said he would file a complaint against the first-term DPK lawmakers, calling their action a "parliamentary coup."

"First-term lawmakers of the DPK have announced that they will impeach Han and all Cabinet members if Ma is not appointed by March 30. This is a parliamentary coup. It is an attempted rebellion to overthrow the government," Kweon said during a press conference Saturday. "Threatening Cabinet members like this is no different from a terrorist warning of beheading."
