The old phrase “guilty and how” seemingly would apply to Mr. Seipp. He was convicted for failing to remain at the scene of an accident. He appealed his conviction but the Supreme Court of Canada dismissed his appeal:
The evidence on which Mr. Seipp relies is that he fled the scene to avoid criminal liability for possession of a stolen vehicle. This is not evidence to the contrary. Rather, it is evidence that Mr. Seipp intended to avoid criminal or civil liability from his care, charge, or control of the vehicle involved in the accident. R. v. Seipp, 2018 SCC 1
Another common reason for suspects failing to remain at the scene of an accident is that there were driving while impaired. Based on Mr. Seipp’s case, and not surprisingly, that would not amount to a defence either.
