Mr Jackson referred himself to the Scottish Legal Complaints Commission (SLCC) after footage revealed the QC making comments in public about the trial of Alex Salmond, who was recently cleared of various sexual offence charges at the High Court in Edinburgh.
The QC said in a statement: “I have intimated my decision to resign as Dean of the Faculty of Advocates, with effect from 30 June, at the latest.
“It would not, however, be appropriate for me to remain as Dean at a time when the Faculty was considering disciplinary proceedings regarding my conduct.
“Accordingly, if, before that date, the Scottish Legal Complaints Commission remits the recent complaint for consideration by the Faculty’s Complaints Committee, I will stand down as Dean immediately. I do not intend to make any further comment.”
