Sec. 2(i), 4
Which entity is the Fiduciary?
Shared platforms across group companies make the determining party ambiguous. The Act attaches duties to whoever determines purpose and means, so the answer has to be recorded per processing activity rather than assumed from the org chart.
Sec. 8(3), 11
Cross-entity sharing is sharing
Moving personal data between group companies is disclosure to another Fiduciary, with the notice and lawful-basis consequences that follow.
Sec. 10
SDF notification by class
Volume and sensitivity make large groups the most likely candidates for Significant Data Fiduciary notification, which switches on DPO, auditor, DPIA and algorithmic duties on a government timetable rather than yours.
