Latin Legal Maxims Reference
Search common Latin legal maxims by phrase or meaning, with literal translation, plain-language sense and a worked example.
A searchable reference of the Latin maxims that appear in common-law judgments, statutes and law-school syllabi, each with its literal translation, what the principle actually does in practice, and a worked example. Search works both ways: type the Latin, or type the idea you half-remember — 'hear the other side' finds audi alteram partem, 'burden of proof' finds actori incumbit onus probandi. Entries are grouped by area, from natural justice and criminal law to the rules of statutory interpretation such as ejusdem generis and noscitur a sociis.

Why use Latin Legal Maxims Reference
Plain-language sense
Every entry says what the principle does in practice, not just what the Latin translates to.
Search by meaning
Matching runs over the translation and the explanation, so you can find a maxim you cannot spell.
Grouped by area
Filter to natural justice, interpretation, evidence or the constitutional writs and read them together.
Common use cases
- Find the maxim behind a principle you can describe but cannot name, before citing it in a memo.
- Check whether the maxim you are about to quote is binding doctrine or, like falsus in uno, only a rule of caution in India.
- Revise the statutory interpretation maxims — ejusdem generis, noscitur a sociis, expressio unius — as one group.
- Explain to a client in plain words what res judicata or locus standi means for their case.
Frequently asked questions
What does audi alteram partem mean?
Hear the other side. It is the rule of natural justice that no one may be condemned without notice of the case against them and a genuine opportunity to answer it. A decision taken without that opportunity can be set aside however strong the underlying evidence, because the defect is in the process rather than the merits.
What is the difference between ratio decidendi and obiter dicta?
The ratio decidendi is the rule of law on which the outcome actually turned, and it is the binding part of a judgment. Obiter dicta are observations made along the way that were not necessary to the decision — persuasive, sometimes very persuasive, but not binding on a later court.
What is the difference between damnum sine injuria and injuria sine damno?
Damnum sine injuria is real loss with no violation of a legal right, and gives no cause of action — losing customers to a lawful competitor is the standard example. Injuria sine damno is the violation of a right with no measurable loss, and is actionable, though the damages may be nominal.
Is falsus in uno, falsus in omnibus applied in India?
Not as a rule of law. Indian courts treat it as a rule of caution: where part of a witness's evidence is untrue or exaggerated, the court sifts the reliable portion from the rest rather than rejecting the testimony wholesale, as courts in some other systems do.
