This is the first handbook of Data Privacy. Butterworths Hong Kong Data Privacy Handbook is a detailed work of reference containing up-to-date materials on the Personal Data (Privacy) Ordinance (Cap 486), the major piece of legislation pertaining to matters on personal data privacy in Hong Kong. The Handbook reproduces the text of the Ordinance as currently in force, together with details on amendments and repeals. The Handbook provides section-by-section annotations to the Ordinance. These annotations encompass significant judicial decisions and rules of court, as well as notes ranging from definitions of words and phrases to discussion on practical aspects and contentious issues relating to particular sections in a succinct format. This Handbook will be an indispensable companion for lawyers, businesspersons, in-house counsels, company directors, company secretaries, judicial officers and all those who are engaged or interested in data privacy in Hong Kong.
