The judge in the influence-peddling trial of Ottawa Mayor Larry O'Brien will announce his verdict on Aug. 12.

Justice Douglas Cunningham made the announcement after 3 p.m. ET Tuesday afternoon after the defence had finished its closing argument and the Crown had completed its 20-minute reply.

Michael Edelson, the lawyer for Ottawa's mayor, declared Monday that the defence wasn't going to call any witness, including O'Brien, which meant both the Crown and the defence could begin closing arguments.

On Tuesday, Edelson continued to attack the credibility of Terry Kilrea, but also outlined what he saw as inconsistencies in the information presented by the witness called by Crown prosecutor Scott Hutchison.

Kilrea, O'Brien's opponent in the 2006 mayoral election, swore an affidavit that he'd received an offer to have his campaign expenses paid and help getting an appointment with the National Parole Board if he dropped out of the race.

Edelson called Kilrea "vindictive, hypocritical, mean-spirited, profane ... that's the Kilrea we're dealing with, that's an insight into the person. He's a mean-spirited hypocrite."

Edelson's argument centred on the fact that some of the witnesses called to testify throughout the trial — such as John Reynolds, David Penner, and federal minister John Baird — supported O'Brien's account, which could, in turn, suggest reasonable doubt.

The Crown began its closing arguments minutes later with prosecutor Scott Hutchison taking only about 20 minutes for his arguments.

Cunningham then announced he would rule when court resumes on Aug. 12.
