Chen Po-sum, the former stock exchange vice-chairman at the heart of a $1.6 million bribery scandal, has been acquitted of eight charges relating to the sale of floor seats.
The 66-year-old mother of three sat stoically in the High Court dock as the jury foreman delivered the verdict.
Her tearful son, Jo-Jo Choy, punched the air in the packed public gallery as the 'not guilty' verdict was delivered.
Aided by her son, Ms Chen pushed through a crowd of well-wishers as she left the court.
Asked if she would continue to sit on the stock exchange membership committee, she replied: 'I am very tired and I just want to go home. I cannot say what I will do beyond tonight.
'I have been confident from the beginning that I would be acquitted. I never doubted that.' Ms Chen was accused of accepting the money in the transfer of A-share exchange seats in 1993 and 1994, when she was convenor of the membership committee.
She said the payments were legal commissions but never informed committee members about the money before or during the approval voting.
