A new (2024) edition of the Equal Treatment Bench Book (ETBB) has been published. As it notes in the preface:
Treating people fairly requires awareness and understanding of their different circumstances, so that there can be effective communication, and so that steps can be taken, where appropriate, to redress any inequality arising from difference or disadvantage. This Bench Book covers some of the important aspects of fair treatment of which all judges should be aware, making some suggestions as to steps that judges may wish to take, in different situations, to ensure that there is fairness for all those who engage in legal proceedings in our courts and tribunals.
And as King LJ notes in her foreword:
Since 2018 it has been published online and, whilst its focus is primarily aimed at all judicial office holders and is written by judges for judges, it has also come to be regarded as an invaluable resource for litigants in person and to many other people connected directly or indirectly with issues relating to equal treatment.
Each chapter has been updated, with significant revisions, in particular, to the chapter on “capacity (mental)”.
