The judges made several important obiter observations: (1) There was discussion about whether the right violated was under section 11(1) (freedom) or section 25(3) (fair trial), with different judges preferring different analyses, though agreeing on the outcome. (2) Extensive comparative analysis was provided of Canadian, American, English, German and European jurisprudence on self-incrimination, interrogation procedures, and immunity. (3) Comments were made on the appropriate breadth of the concept of 'freedom' in section 11(1), with Ackermann J advocating a broad approach and Chaskalson P, Mokgoro J and Sachs J cautioning against too expansive an interpretation that would subject all regulatory legislation to strict scrutiny. (4) Discussion of the relationship between enumerated rights in Chapter 3 and residual rights under section 11(1). (5) Comments on the two-stage approach to constitutional adjudication and the danger of 'definitional balancing' at the first stage. (6) Observations about the importance of procedural safeguards to freedom and the role of courts in a constitutional democracy. (7) Discussion of the differences between the adversarial and inquisitorial systems of criminal justice. (8) Comments on the distinction between 'real evidence' that exists independently and compelled testimonial evidence. (9) Various judges noted that broader challenges to sections 417 and 418 might arise in other cases (indeed, Bernstein had been argued but not yet decided).
