Live: President Yoon's lawyers ask Constitutional Court to delay impeachment trial due to his arrest

The second hearing of President Yoon's impeachment trial takes place today, after justices adjourned the first meeting due to his nonappearance.

Given his arrest on Wednesday, his lawyers have asked for the hearing to be rescheduled.

We now head over to the Constitutional Court with our Oh Soo-young standing by.

1. Sooyoung, for obvious reasons, the President cannot attend Thursday's trial.

That's right. President Yoon's legal team has requested the Constitutional Court to postpone the second impeachment trial hearing, scheduled for 2PM on Thursday.

This came after the President's detainment and interrogation by state investigators from Wednesday morning until late into the night.

Yoon's lawyers reportedly claimed that holding a hearing during his detention violates his right to go to court as the respondent.

As he already missed his first session,. if he does not attend Thursday's hearing, justices can proceed to begin a full-fledged trial without him.

We have yet to hear whether the Court will agree to postpone the session, but if it goes ahead, we're likely to see strong protests from Yoon's lawyers.

The trial already has had a rocky start, with the President's legal team filing a series of objections to the Court.

These include an objection to the first hearing, and the Court's decision to fix five hearing dates without consultation both of which the panel rejected.

Yoon's side has also objected to the Court's decision to accept ongoing investigation records as evidence, saying this violates trial rules.

His team has further cited security concerns in attending the trial, filing for an injunction against arrest warrants by state investigators.

2. Remind us of the key points and arguments expected to the raised in the trial.

Sure, but at this point it's hard to expect smooth debates with organised arguments, as President Yoon's team and the National Assembly's panel trying to impeach him failed to narrow their differences over the main grounds of argument in two pre-trial hearings.

Initially, the National Assembly set out four or five main grounds for impeachment including the declaration of martial law on December 3, and various actions which they claim disrupted the Constitutional order.

In a written response to the Court on Tuesday, Yoon's team claimed martial law was justified due to "suspicions of election fraud," and the opposition-led parliament sabotaging governance, among other reasons that put the country in a "state of crisis" akin to war or a national emergency.

But the biggest point of contention continues to be whether 'insurrection' stands as a main ground for impeachment.

The National Assembly's panel withdrew it from their argument, as they want to speed up the verdict.

But Yoon's side argues that the Assembly cited insurrection as a major reason for impeachment in their resolution, so removing it from the debate undermines the trial's legitimacy.

Court justices have been 'comprehensively reviewing' the matter, but until now, they have been focusing speeding up the trial.

Thank you for keeping us updated Sooyoung.
