Procedural Posture

Trade Practices Act 1974 (cth) Ss 52, 53(c) and 53(d) and Passing Off Proceeding Involving Use of Cadbury Purple in Chocolate Confectionery Business / Evidentiary Ruling on Respondent's Objection to Admission of Two Affidavits of Dr Brian John Gibbs

Legal Issues

  1. 1 ['Whether the affidavits of Dr Brian John Gibbs satisfied s 79 of the Evidence Act 1995 (Cth) as opinion evidence based on specialised knowledge.' 'Whether opinion evidence about likely consumer behaviour in purchasing everyday chocolate products was outside the knowledge and experience of a trier of fact.' 'Whether the affidavits should alternatively be excluded under s 135 of the Evidence Act 1995 (Cth).']

Ratio Decidendi

Although Marketing and Behavioural Science was an organised and recognised area of specialised knowledge and Dr Gibbs was qualified in it, the issues in the proceeding concerned retail purchasing decisions by ordinary consumers of an inexpensive everyday product. Those issues were within the knowledge and experience of a trier of fact and concerned ordinary human behaviour, so the affidavits were not admissible under s 79. If admissible, the affidavits would in any event have been excluded under s 135 because their limited probative value was outweighed by risks of confusion, disputation, complication and waste of time.

Court Disposition

Affidavits excluded; respondent's objection upheld.

Orders

  • ['The affidavits of Brian John Gibbs are not admitted into evidence.']
