Definition
The principle of statutory interpretation that statutes dealing with the same subject matter should be read and interpreted together harmoniously — a term in one statute that is also used in a related statute on the same subject is presumed to bear the same meaning.
The principle of 'in pari materia' (Latin: 'on like subject matter') holds that statutes dealing with the same subject matter should be construed together as a coherent body of law. When a term appears in multiple statutes dealing with the same subject, the meaning established in one statute may be adopted in interpreting the same term in another related statute, unless there is a clear indication that different meanings are intended. This principle promotes consistency in the legal treatment of a subject matter and prevents the same word from meaning different things in different statutes dealing with identical or closely related issues.
Statutory Definition
No statutory definition — pari materia is a canon of statutory construction developed through case law. The General Clauses Act, 1897 (Section 3) provides definitions for terms used across statutes — this is a statutory embodiment of the pari materia principle. Courts apply the principle when: (a) two statutes deal with the same subject or same class of persons; (b) a term is used in both without separate definition; and (c) there is no clear indication that different meanings are intended.
Etymology & Origin
Latin 'in pari materia' (in like matter) from 'in' (in) + 'par/pari' (equal, like) + 'materia' (matter, subject). Statutes 'in pari materia' are those 'in the same matter' — dealing with the same legal subject.

Pari Materia: Reading Related Laws Together
Law is not written in isolation — statutes on the same subject form a legislative framework that should be read as a coherent whole. The pari materia principle prevents the absurdity of the same word meaning one thing in the Income Tax Act and something entirely different in the Wealth Tax Act, when both deal with the same subject of direct taxation. Courts read statutes in pari materia together to produce consistent, coherent law.
Application in Indian Courts
Indian courts have applied the pari materia principle in numerous contexts: (a) Banking legislation: Terms defined in the Banking Regulation Act interpreted similarly in the Reserve Bank of India Act and the Companies Act when applied to banking companies. (b) Labour legislation: The definition of 'workman' under the Industrial Disputes Act has been used to interpret the same term in the Factories Act when the subject matter (labour relations) is the same. (c) Criminal statutes: Offences defined in the IPC (now BNS) are read consistently with corresponding offences in special statutes (NDPS, PMLA) when the subject matter overlaps.
Limits of Pari Materia
The principle does not apply mechanically: (a) A later statute may deliberately give a different meaning to a term — the legislative intent to depart from the earlier meaning overrides the pari materia presumption. (b) Where the context of the two statutes is sufficiently different, the same word may legitimately bear different meanings — 'person' in a tax statute may include companies; 'person' in a personal rights statute may not. (c) A specific statutory definition in one statute does not automatically override a different definition or meaning in another statute — the pari materia principle applies as a default, not an absolute rule.
“Pari materia is the law of legislative consistency — the presumption that Parliament does not speak with forked tongue on the same subject. When two statutes address the same matter, they should be read as one mind speaking through two documents, not as two independent voices in potential conflict.”
