Lawyers for South Korean President Park Geun-hye asked on Friday to overturn her impeachment by petitioning the Constitutional Court to delay its ruling or dismiss the case, Yonhap news agency reported.
The court's ruling on whether to oust or reinstate the president is widely expected to come no later than March 13 when one of the justices retires. "There are many reasons cited for the impeachment, and it is a complicated case, so it is hoped that (the court) will work to complete deliberations before Justice Lee Jung-mi's retirement rather than try to deliver a ruling by that date, and thus secure sufficient time for fact-finding and legal judgment," Lee She-yoon, a lawyer and former Constitutional Court justice, said in an "expert's opinion" submitted to the court. 
Park was impeached by the country's National Assembly on Dec. 9 for allegedly letting her friend Choi Soon-sil influence state policymaking and colluding with her to extort money from local conglomerates.
