The General Legal Council (GLC) confirmed on Tuesday that a three-member disciplinary panel ordered on June 18 that Pearson be disbarred.
In a last-minute bid to retain his licence, Pearson reportedly filed an application with the GLC seeking to have the decision of the disciplinary panel put on hold.
He was found guilty of professional misconduct on October 12 last year, the GLC confirmed.
Pearson is the latest in a string of well-known attorneys who have been disbarred in recent years.
Since the start of the year, three attorneys have been struck from the list of lawyers authorised to practise in Jamaica.
