Legal Maxims & Fundamental Terminology

Latin legal maxims serve as concise jurisprudential principles that guide judicial interpretation, procedural fairness, and statutory construction across common law systems. Natural justice relies on two cardinal maxims: Nemo Judex In Causa Sua (no one should be a judge in their own cause, preventing bias) and Audi Alteram Partem (hear the other side, guaranteeing fair hearing). Procedural finality in civil litigation is governed by Res Judicata (Section 11 of the Code of Civil Procedure), barring re-litigation of already decided matters. Criminal liability requires both Actus Reus (the prohibited act) and Mens Rea (the guilty mind). Other vital maxims include Ubi Jus Ibi Remedium (where there is a right, there is a remedy) and Damnum Sine Injuria (damage without legal injury). Legal reasoning exams assess the precise application of these doctrines.
