Cause — in plain language

Plain language

a reason or justification that makes something legally right or wrong, or the thing that brings about a particular result or effect

• reason or justification
• grounds for action
• what brings about a result
• legal justification

What to watch for

• The everyday meaning of 'cause' as 'reason' is close but misses the legal precision. Legal 'cause' often refers to specific standards like 'probable cause' or 'just cause' that have technical requirements.
• In employment law, 'for cause' has a specific meaning that is narrower than everyday usage. It typically requires serious misconduct, not just poor performance or personality conflicts.
• In tort cases, 'cause' splits into 'cause in fact' (but-for cause) and 'proximate cause' (legal cause). Using the same plain-language phrase for both loses an important legal distinction.
• The phrase 'for cause' in contracts usually refers to termination rights, not general justification. Translating it as simply 'for a reason' misses the specific legal consequences.

Why This Term Is Hard to Translate. "Cause" looks like an everyday word, but it carries specific legal meanings that depend entirely on context. The same word might refer to grounds for termination in an employment contract, evidence standards in criminal procedure, or causation in a personal injury case. Each meaning requires a different plain-language approach.

What to Watch For.

• Employment context: "For cause" termination usually requires serious misconduct like theft, fraud, or gross negligence — not just poor performance. The plain-language version should reflect this higher standard.
• Criminal context: "Probable cause" is a specific legal standard requiring facts and circumstances that would lead a reasonable person to believe a crime occurred.
• Tort context: Distinguish between "cause in fact" (the but-for test) and "proximate cause" (the legal cause that matters for liability).

Common Misunderstandings by Non-Lawyers.

• "'Cause' just means any reason." (No — legal cause has specific meanings that vary by context and often require meeting particular standards.)
• "If I don't like my boss, that's cause for firing." (Wrong — employment 'cause' typically requires serious misconduct, not personality conflicts.)
• "Anything that contributed to an accident is the legal cause." (Not true — only the primary or proximate cause matters for liability, not every contributing factor.)

Legal definition

A reason or justification that makes something legally right or wrong, or the thing that brings about a particular result. In law, "cause" can mean different things depending on the situation: it might be the grounds for firing someone, the evidence needed to arrest a person, or the main factor that led to someone getting hurt.

Meanings by context

employment law: Serious misconduct or poor performance that allows an employer to fire someone without following normal procedures.

criminal law: Enough evidence to reasonably believe someone committed a crime.

tort law: The main thing that actually caused the injury, not just something that happened around the same time.
