The binding legal principles established are: (1) A distributor or licensee of copyright material has locus standi to participate in infringement proceedings where they can demonstrate a legitimate commercial interest, even if the precise scope of their licensing rights is disputed. (2) Under section 1 of the Copyright Act 98 of 1978, an imported article constitutes an 'infringing copy' if its manufacture in South Africa would have constituted copyright infringement, regardless of whether it was lawfully acquired in the country of origin. (3) In exercising the discretion under section 24(1) to order delivery up of infringing copies, the court may properly consider: the necessity of the order to enforce interdicts, the number of infringers involved, the absence of any lawful use for the infringing articles in South Africa, and the past conduct of infringers indicating likelihood of continued infringement. (4) Territorial copyright restrictions, including regional encoding systems, are enforceable in South Africa, and deliberate circumvention of such systems to exploit copyright works outside the authorized territory constitutes actionable infringement.
