Dicey Morris & Collins

Dicey, Morris & Collins on the Conflict of Laws (often simply Dicey, Morris & Collins, or even just Dicey & Morris) is the leading English law textbook on the conflict of laws (ISBN 978-0-414-02453-3). It has been described as the "gold standard" in terms of academic writing on the subject,[1] and the "foremost authority on private international law".[2]

Dicey, Morris & Collins, 14th edition.



The textbook has had three principal general editors during its life:

Since 2015, Professor Jonathan Harris QC has been joint general editor with Lord Collins of Mapesbury.[3]

Between 1922 and 1949 A. Berriedale Keith was also a general editor of the text, but has not been honoured with a permanent place in the book's title.

In the most recent edition, the team of editors includes Professor C G J Morse, Professor David McClean, Professor Adrian Briggs, Professor Jonathan Harris, Professor Campbell McLachlan QC, Professor Andrew Dickinson and Professor Peter McEleavy.[2]



The first edition was published in 1896 under the title A Digest of the Law of England with reference to the Conflict of Laws. The 16th and most recent edition was published in 2022.

Unusually for an academic textbook, Dicey, Morris & Collins is set out in a series of "Rules". The format dates from the time when there was relatively little case law or statute law on the subject, and A.V. Dicey tried to formulate the text from first principles. The format became something of a self-fulfilling prophecy as during the evolution of the subject judges would often cite rules in the textbook as authoritative propositions for their rulings (see for example, Singularis Holdings Limited v PricewaterhouseCoopers [2014] UKPC 36 at paragraph 12[4]).
