/keɪs ʌv ðə fɜrst ɪmˈprɛʃən/ – Phrase
Definition: vụ án chưa có tiền lệ, vụ án đặt ra vấn đề pháp lý đầu tiên.
A more thorough explanation: A “case of first impression” refers to a legal case in which a particular issue or question is presented to a court for the first time, without any prior legal precedent or established principles to guide the court’s decision. In such cases, the court must analyze the facts and legal arguments presented to make a determination that may set a new precedent for future cases involving similar issues.
Example: In the case of the first impression, the court must carefully consider the novel legal issue presented and make a decision that will set a precedent for future cases.
