Dear Intern,

To fulfil our 2022 risk assessment strategy, our team is required to investigate whether all aspects of CTB's new AR software - Change Room 3.0 - comply with Australian laws and regulations. Since you are currently studying 'LAW101' at university, we would like you to tackle some preliminary questions concerning the legal and regulatory context of this software. To this end, we require thorough answers to the following question.

To guide in determining the legal principles that may regulate the functionality and use of AR software, explain:

(a) Whether 'Ethics-by-Design Guidelines'*, developed for the technology industry by a multidisciplinary non-profit organisation, is considered binding 'law'; and

(b) The difference, using relevant examples, between 'public law' and 'private law'?
