Mokgoro J made extensive obiter comments on the philosophy underlying freedom of expression, noting that it serves both a 'marketplace of ideas' function and, more importantly, underpins each individual's empowerment to autonomous self-development and is foundational to human dignity. She noted that section 15 should be read not in isolation but as part of a web of mutually supporting rights. She extensively reviewed foreign jurisprudence from the United States, Canada, India, Zimbabwe and Europe on obscenity law and the right to receive information, while cautioning that the application of obscenity laws in these jurisdictions had sometimes resulted in discriminatory enforcement against marginalized groups and culturally subordinated communities. The judgment deliberately left open the question of what form of regulation of sexually explicit material would be constitutionally permissible, particularly in relation to child pornography, material involving violence, exploitation, degradation of women and children. Didcott J emphasized the importance of not pre-empting future cases, given that new legislation was in preparation to replace the existing censorship regime. Langa J and Madala J stressed that the right to privacy, while broad, is not absolute and may be limited in appropriate circumstances, particularly regarding children and exploitative material. Sachs J identified 'strategic overbreadth' as an additional fatal defect - the Act's failure to distinguish between possession in private versus for sale, or between what is offensive versus harmful, and its lack of any attempt to balance competing constitutional values.
