Court procedure
Actus curiae neminem gravabit
An act of the court should harm no one.
Courts may correct prejudice caused by their own acts. Its application depends on the facts and the relief legally available.
Natural justice
Audi alteram partem
Hear the other side.
A person affected by a decision should have a fair opportunity to be heard. The required procedure depends on the statute and circumstances.
Equity and remedies
Commodum ex injuria sua nemo habere debet
No one should benefit from their own wrong.
A party should not gain a legal advantage through its own wrongful conduct, including misuse of court proceedings.
Statutory interpretation
Ejusdem generis
Of the same kind.
General words following a specific list may be limited to the same identifiable class. Legislative purpose and context can require a broader reading.
Natural justice
Nemo judex in causa sua
No one should judge their own cause.
Decision-makers must be impartial. This principle addresses bias and conflicts of interest in adjudication.
Statutory interpretation
Noscitur a sociis
A word is understood by its companions.
Surrounding words can help resolve the meaning of an ambiguous expression. The statutory context remains controlling.
Evidence and negligence
Res ipsa loquitur
The thing speaks for itself.
The circumstances of an accident may support an inference of negligence. The inference depends on the evidence and is not automatic.
Civil remedies
Ubi jus ibi remedium
Where there is a right, there is a remedy.
The recognition of a legal right ordinarily carries a means of enforcing it, subject to statutory jurisdiction and procedural rules.
