/əˈrɪdʒənl ˈækʃən/ – Phrase
Definition: đơn kiện gốc.
A more thorough explanation: An original action refers to a legal proceeding initiated in a court that has original jurisdiction over the matter, as opposed to an appellate court that reviews decisions made by lower courts. In this context, an original action is typically the first legal proceeding in a particular matter, rather than an appeal or other type of review.
Example: In the original action filed by the plaintiff, they alleged breach of contract by the defendant.
