Part 7: Bulk personal dataset warrants Section 203: Meaning of "protected data"
This section defines "protected data" as any data contained in a bulk personal dataset other than data which is one or more of the following: systems data (as defined in section 263(4)); data which is not private information (so in other words, private information is protected data); or identifying data which is capable of being logically separated from the dataset and, if it were so separated, would not reveal anything which could reasonably be considered the meaning of the rest of the data which would remain in the dataset.
	Systems data is essentially data that enables or facilitates the functioning of any system or service. Identifying data may help to identify persons, systems, services, locations or events. If the data cannot be classified either as systems data or identifying data, then it will fall within the definition of protected data so long as it is private information. The term private information includes information relating to a person's private or family life. Data which may not fall within the definition of private information could include that which is publicly available, such as information from books, newspapers, TV and radio broadcasts or data that is freely available on-line. Protected data in a bulk personal dataset may therefore include, for example, the contents of letters, e-mails or other documents.
