It was refused by PCO.
Paragraph 24 of the investigation report states, “However, should additional evidence be uncovered corroborating a criminal intent to obstruct justice, it would be recommended that the occurrence be reopened for further investigation.”
I have a really tough time understanding, in the face of the obstruction that the RCMP was facing by the Prime Minister and the consequent lack of evidence to further pursue getting to the heart of the issue—that being obstruction—why the RCMP didn't see fit to even pick up the phone and contact the Prime Minister and schedule an interview with him.
