Just as a legal concept denotes fairness and conformity to law, shaping interpretation of rights and obligations. The term just denotes conformity to law and moral rectitude, encompassing fairness, equity and reasonableness; it signifies that an act or claim is lawful, well founded and legitimate rather than merely subjectively fair. Context-sensitive, the word also functions adverbially to indicate immediacy, and doctrinally to denote lawful ground, requiring analysis of whether moral justice, positive legal rights, reasonableness, or temporal immediacy governs interpretation and entitlement.
