🏛️ Introduction: Understanding Aids to Interpretation
The interpretation of statutes is the art of discovering the true meaning of the language used by the legislature. However, statutes often contain ambiguities, omissions, or conflicting expressions.
To resolve such uncertainties, courts rely on “Aids to Interpretation.”
🔹 Definition:
“Aids to interpretation” are the tools or resources that assist the judiciary in understanding, explaining, and applying statutory provisions in a meaningful way consistent with legislative intent.
🔹 Classification:
Aids to interpretation are broadly divided into two categories:
-
Internal Aids – Found within the statute itself.
-
External Aids – Found outside the statute but relevant for interpretation.
