Source Policy
Last reviewed: May 2026
Every claim of law on UK Law Reference must be traceable to a primary source. This page explains the hierarchy of sources we use, how we cite them, when secondary sources are acceptable, and how we approach foreign and international law.

When Secondary Sources Are Acceptable
Secondary sources are used where:
- A primary source states the rule but does not explain the reasoning usefully for a general audience
- The development of a legal doctrine over time is being traced
- A legal concept is better explained through authoritative commentary than raw primary sources
- There is a specific interpretative dispute where established commentary has crystallised the arguments
Secondary sources are never used where a primary source directly answers the question.
Foreign Law Sources
We reference foreign and international law only where it has direct bearing on UK law:
- EU retained law — sourced from legislation.gov.uk and EUR-Lex
- ECHR — Convention text from the Council of Europe; ECtHR judgments cited by application number
- International conventions — cited in treaty form with domestic implementing legislation
- Commonwealth jurisdictions — clearly identified as persuasive only, with weight noted
Source Verification
All external links are checked at time of writing or review. We do not link to unofficial summarisation sites, legal advice forums, or AI-generated legal content as sources. We do not treat Wikipedia as a source of legal authority. Report broken links via our corrections inbox.
