The former ACT director of public prosecutions Shane Drumgold, SC, says he is “delighted” by a court’s finding that the inquiry into the trial of Liberal staffer Bruce Lehrmann for sexual assault had been infected by bias.

Acting Justice Stephen Kaye declared on Monday that a “fair-minded observer” would conclude that the head of the inquiry, former judge Walter Sofronoff, KC had been “influenced by the views” of Janet Albrechtsen of The Australian.
