6. 6 Personal Data in Public Domain still Subject to PDPO  Government confirmed LRC’s view “putting personal data in the public domain does not make the data available for use for any purpose”  Hon Chu JA in Re Hui Kee Chun, CACV 4/2012 DPP3 “is directed against the misuse of personal data and it matters not that the personal data involved has been published elsewhere or is publicly available”
