Plain language
a specific instruction, regulation, or principle that dictates how something must be done or how a decision must be made
- regulation
- requirement
- standard
- procedure
- guideline
What to watch for
- Non-lawyers often confuse 'rule' with 'law.' A rule is often a specific, technical requirement (like Rule 144), whereas a law is a broader legislative act. Using them interchangeably can obscure the source of the requirement.
- In a courtroom, 'to rule' is a verb meaning to decide. Translators must ensure they don't confuse the noun (a regulation) with the verb (a judge's decision).
- When a document refers to a 'Rule' (capitalized), it usually points to a specific, numbered section of a code of procedure. Translating it as a generic 'guideline' loses the reference to the specific legal source.
Distinguishing from Similar Terms.
- Rule vs. Statute: A statute is a law passed by a legislature (like Congress). A rule is often a more detailed regulation created by an agency or a court to explain how that law works in practice.
- Rule vs. Order: An order is usually a specific command from a judge directed at the people involved in a single case. A rule is a general standard that applies to everyone in similar situations.
Common Misunderstandings by Non-Lawyers.
- "A rule is just a suggestion." (No — in a legal context, a rule is a mandatory requirement that carries legal consequences if ignored.)
- "Rules are only for courts." (No — government agencies create rules that affect businesses and individuals every day, such as environmental or financial regulations.)
What to Watch For.
- Numbered Rules: When you see "Rule" followed by a number (e.g., Rule 10b-5), it is a formal citation. Do not translate the number away; it is the "address" of the specific legal requirement.
