/fɔrˈməl lɔː/ – Phrase
Definition: luật thủ tục, luật tố tụng.
A more throughout explanation: Formal law refers to laws that are written and codified, typically enacted by a legislative body or other governing authority. These laws are officially recognized and enforced by the government, and they provide a framework for regulating behavior and resolving disputes within a society. Formal laws are distinguished from customary laws or informal norms, as they are explicitly defined and documented in legal statutes or regulations.
Example: The formal law requires all individuals to wear a seatbelt while driving a motor vehicle.
