There’s no formal vote but if you have a page where two people have a long discussion of A vs B and a few other people take position A (and write a sensible comment—“I support A” might not be enough) but no additional person takes position B according to Wikipedia policy there’s consensus for A.
Then when the page gets changed to A it’s invalid for anybody to switch it to B. The lines around what counts as consensus are a bit fuzzy but in general that’s the decision making process. If people don’t agree on what consensus is conflicts can be escalated.
