/dɪˈskrɛʃəˌnɛri rul/ – Phrase
Definition: quy phạm tùy nghi.
A more thorough explanation: A discretionary rule is a legal principle or standard that allows a judge or decision-maker to use their own judgment or discretion in applying the rule to a particular case or situation. This means that the rule is not absolute or mandatory, but rather gives the decision-maker the flexibility to consider the specific circumstances and make a decision based on their own judgment.
Example: The judge applied a discretionary rule when deciding to admit the new evidence in the case.
