Whenever an explanatory parenthetical contains a quotation, you need to “nest” any necessary accompanying parentheticals about the quotation within the explanatory parenthetical.
The following is an example of how this looks. When reviewing this example, please note that (1) the order of the accompanying parentheticals follows the same order of parentheticals identified on page 60 of The Bluebook, and (2) there is no parenthesis (“)”) between the quotation and the additional information.
Things can get a bit tricky (visually, at least) when an explanatory parenthetical with a quotation is added to a citation that is already supporting an in-text quotation. Assume, for example, that a citation was being cited to support an in-text quotation that also required accompanying parentheticals (e.g., “alteration in original” and “footnote omitted”).
