This document discusses various internal aids to interpretation of statutes under Bangladesh law, including: 1) Short titles, long titles, preambles, marginal notes, headings, explanations and schedules which provide context and guidance on the intent and scope of legislation. 2) Internal aids like preambles are not used to defeat enacting clauses but to guide interpretation, while marginal notes are not legally binding. 3) Illustrations appended to sections are also valuable in understanding the real scope of laws. 4) Case law principles establish that schedules form part of statutes but cannot override express provisions, and inconsistencies between schedules and Acts result in the Act prevailing.
