Intrinsic and Extrinsic Aids in Statutory Interpretation
This page introduces the concept of statutory interpretation and the aids used to understand and apply legislation. It focuses on two main categories: intrinsic and extrinsic aids.
Intrinsic Aids
Intrinsic aids are internal elements found within the Act itself, such as headings, sub-headings, and marginal notes. These aids help clarify the meaning and scope of statutory provisions.
Example: Section 4 of the Theft Act 1968 defines 'property' to include money and all other property, real or personal. Similarly, Section 9 of the same Act extends the definition of 'buildings' to include 'inhabited vehicles', thus encompassing caravans.
The use of intrinsic aids offers several advantages:
- It increases the likelihood of courts interpreting the Act as Parliament intended.
- It provides greater certainty in legal interpretation.
- It shows respect for parliamentary intent.
- It offers quick and easy access to relevant information.
However, intrinsic aids also have limitations:
- Definitions are not always provided for all terms, as seen with "dishonesty" in the Theft Act 1968.
- They may not always prevent harsh or absurd decisions.
- They are not included in every statute.
Extrinsic Aids
Extrinsic aids are external sources used to interpret statutes, including dictionaries, Law Commission reports, previous case law, and Hansard theofficialrecordofparliamentarydebates.
Example: In DPP v Cheeseman, the Oxford English Dictionary from 1847 was used to interpret an Act from the same year.
A significant development in the use of extrinsic aids occurred in the Pepper v Hart case 1993, where the House of Lords relaxed rules regarding the use of Hansard in statutory interpretation.
Advantages of using Hansard include:
- It is publicly available for consultation.
- It can clarify statutory language.
- It provides insight into the reasons behind the Act's creation.
However, using Hansard also has disadvantages:
- There's a risk of focusing on irrelevant material.
- The specific words in question may not be mentioned in the debate.
- It can lead to additional costs as lawyers feel obliged to review debates to avoid negligence claims.
Highlight: The use of both intrinsic and extrinsic aids in statutory interpretation is crucial for A Level law students to understand, as it forms a fundamental part of legal analysis and application.
