What happens if the losing side at a provincial court of appeal abandons the matter?

When the losing side at a provincial court of appeal abandons the matter, the ruling made by the court stands as the final decision in that case. Consequently, this ruling becomes law within the province because it establishes a precedent that can influence future cases or legal interpretations.

In the context of the Canadian legal system, once an appeal is abandoned, the lower court's decision is effectively upheld and has the force of law. This does not mean that the decision is universally applicable across all provinces unless it is a Supreme Court ruling; however, within the jurisdiction of the province where the ruling was made, it is binding.

The other options reflect misunderstandings of the legal processes involved. An overturned ruling would imply that a subsequent decision has modified or annulled the original ruling, which does not occur when an appeal is abandoned. The Supreme Court hearing the case would require an active appeal rather than abandonment, and sending the case back to the trial division implies ongoing litigation, which does not happen when a party chooses not to pursue the matter further.
