The Law Reports, produced by the Incorporated Council for Law Reporting (ICLR), are the most authoritative and should be cited principally. They provide detailed accounts of significant cases and are preferred for their comprehensiveness and reliability. If a report from The Law Reports is unavailable, other sources like the Weekly Law Reports or specialist law reports may be used.

Key Point: Citing the correct law reports is essential for ensuring the accuracy and authority of legal references, which is critical in legal practice and scholarship.
