"Principles of Statutory Interpretation" is a foundational text that delves into the methods and principles used by courts and legal professionals to interpret and apply statutes. Statutory interpretation is a critical aspect of legal practice, as it ensures that the law is applied in a way that reflects legislative intent while maintaining consistency and fairness.

The book covers key interpretation principles, including:

1. Literal Rule: Interpreting the statute according to the plain, ordinary meaning of the words, unless it leads to absurd or unreasonable results.

2. Golden Rule: Modifying the literal meaning of a word or phrase if its plain meaning leads to an absurdity or conflict with the rest of the statute.

3. Mischief Rule: Identifying the "mischief" or problem that the statute was intended to address and interpreting it in a way that remedies that issue.

4. Purposive Approach: Focusing on the purpose behind the legislation, rather than just the literal meaning of its provisions, to achieve the intended effect.

5. Ejusdem Generis: A rule of interpretation that limits the general meaning of words to the same category or class as the specific words listed before them.

6. Noscitur a Sociis: Interpreting a word based on the context of the other words with which it is associated.
