The Crown is urging the judge to find Ottawa mayor Larry O'Brien guilty.

O'Brien was not called to the witness stand on Monday. The defence rested its case without presenting evidence.

The court heard closing arguments from the Crown Monday morning and will hear from the defence throughout the afternoon.

In closing arguments, Crown Scott Hutchison says this case is not just about Terry Kilrea's testimony.

He says it is about "a matrix of corroborative evidence that should, at the end of the day, overcome any issue the defence has with Terry Kilrea's credibility."

Hutchison also says O'Brien's version is inconsistent with a number of material facts presented before the court.

However, the Crown has recognized the discrepancies in the details Kilrea could recall. The team is asking the judge to place little value on this when considering Kilrea's credibility.

"It's not like Terry Kilrea made up the meeting." Hutchison went on to say, "it doesn't matter that he couldn't remember dates and times."

Defence attorney Michael Edelson told the courts "...it was evasive at times, unresponsive, incoherent, obtuse, inconsistent and at times false and untrue," in reference to Terry Kilrea's testimony.

The charges against the mayor stem from allegations he encouraged fellow mayoral candidate Terry Kilrea to drop out of the 2006 municipal race in exchange for a federal appointment to the National Parole Board.

Edelson's closing arguments could continue into Tuesday.

It may be weeks before Justice Cunningham gives the final verdict.
