Is anyone aware of an authoritative rule on how to use quotation marks for a statement that has been repeated in its entirety from one speaker, to a second, to a third, to a fourth, to a . . . . . .?
I understand basic nesting rules, but my (law) firm follows a convention that results in the following punctuation if a statement has been "passed down" through a series of speakers: "'"'"What goes up must come down."'"'"
This seems insane to me, but I can't find a "rule" that says to stop nesting entire quotes at a certain level.
I'm certainly interested in the group consensus, but even more interested in something authoritative.
