The defence team quit en masse on Monday, when Park condemned the trial as "political revenge", after her detention warrant was extended for another six months.
Park -- who faces multiple charges including bribery, coercion and abuse of power for offering governmental favours to tycoons -- refused to attend the Seoul Central District Court today, citing her allegedly poor health.
The court had urged her lawyers to reconsider their resignations "to prevent possible disadvantages to the accused" but they had not withdrawn them, senior judge Kim Se-Yun told the hearing.
He adjourned the proceedings to an unspecified date.
The process is likely to take some time as the defendant's new representatives will have to review more than 100,000 pages of evidence.
