You are a lawyer, but those who aren't might be under the impression that some sort of wall separates the two and that no attention is paid to what happens on the other side, but that's not the case. Judges pay a lot of attention, if only when assessing damages. Concepts rooted in common law have been integrated in Quebec, and similarly, certain civil law notions are considered in common law jurisdictions. Ultimately, judges want to issue rulings that make sense, sensible judgments, and if other courts have already ruled that certain concepts make sense, judges will find reassurance in that and make judgments that will shape the case law going forward.
