Commentary for Bava Metzia 47:10

אם תמצא לומר הלכה כמותו דוקא ברוב כנענים או אפילו ברוב ישראל

but not where the majority are Israelites, or [did he say this] also [with regard to things found in places] where the majority are Israelites? And if you come to the conclusion that [he said this] also where the majority are Israelites do the Rabbis differ from him or not? And if you come to the conclusion that they differ from him — they would certainly differ where the majority are Israelites — do they differ where the majority are heathens, or not?<span class="x" onmousemove="('comment',' [In view of the principle that we do not follow the majority in money matters.] ');">⁹</span>
