Terrence Robertson told reporters Monday he should never have taken a job as special prosecutor investigating Kash Heed's campaign, and said he has returned all legal fees paid to him.
Robertson stepped down as special prosecutor May 4, after it was revealed that both he and his law firm made political donations to the BC Liberals.
"At that time, I decided that contributions from my firm…did not compromise my independence as a prosecutor," Robertson said in a prepared statement Monday.
"In hindsight, I was wrong to think these donations would not raise questions about my independence."
Despite saying that he is "truly sorry" for taking the job, Robertson maintained that he acted independently during his time as special prosecutor.
"I am confident that my judgment was made independently and that I was not influenced in any way in the decision as to what charges should be approved."
Robertson's law firm, Harper Grey LLP, is a regular contributor to the BC Liberal Party, donating $8,500 to the party's 2009 election campaign alone. The firm contributed $1,000 to Heed's election campaign last year.
Robertson individually donated $1,000 to the party in 2009.
Harper Grey released a statement Monday saying that the firm will no longer make any political donations.
The firm also said that it had returned all legal fees paid to Robertson during his term as special prosecutor.
Prior to his resignation, Robertson had cleared Heed of all wrongdoing in connection to the distribution of pamphlets containing inflammatory statements about the NDP's platform during last year's election campaign.
They were deemed illegal because they didn't contain required information about who paid for them.
Under Robertson's watch, Heed's campaign manager Barinder Sall was charged with three criminal and three Election Act offences in connection to the flyers.
The campaign's financial officer Satpal Johl is facing one Election Act charge.
Vancouver lawyer Peter Wilson was appointed as the new special prosecutor in the case on Friday.
