/ˈdjuːpəli/ – noun
Definition: (Scot) bản phản bác lần thứ hai của bị đơn, phản bác lần thứ hai.
A more thorough explanation: In legal context, duply refers to a legal pleading in Scottish law and old common law. It is a response made by a defendant to a plaintiff’s replie (or reply), essentially a counter-response to the arguments raised by the plaintiff in their reply. It is the third stage in the sequence of pleadings.
Example: In a civil case, after the plaintiff filed a replie to the defendant’s initial response, the defendant’s lawyer submitted a duply addressing the points raised in the plaintiff’s response.
