MAJORITY OBITER:
1. Policy on preliminary litigation: As a general matter, challenges to search warrants should preferably be heard by trial courts under section 35(5) rather than in preliminary proceedings. This allows the trial court (best placed to balance competing interests) to consider unlawfulness and admissibility together, and avoids delays in commencing trials. However, courts cannot adopt an absolute policy refusing to hear such challenges, as this may violate sections 34 and 38 (access to courts). Once an appellate court has ruled on validity, collateral challenge at trial is impermissible. (Paras 62-67, 242-246)
2. Interpretation of section 29(1): The broad power to seize anything that "might have a bearing" on an investigation should not be read literally to authorize unlimited searches. It must be read with section 29(2) requiring strict regard for dignity and privacy. Investigators should restrict searches to classes of items they have reason to believe might be relevant, and must have a reason (not mere hope) for examining items. (Paras 138-146)
3. Section 29(9)(b): "Particulars regarding authority" should be interpreted broadly to include particulars about the scope of the search, not just the delegation of authority to the particular investigator. This enables searched persons to understand the ambit of the search by asking questions. (Paras 148-150)
4. Catch-all paragraphs generally: These are not necessarily invalid. Investigators cannot foresee every relevant class of document. They may examine unforeseen items if they have reason to believe relevance, but must respect privacy and dignity. (Paras 175-176)
5. Section 29(11) temporal scope: The privilege protection mechanism in section 29(11) applies only "during execution" of a warrant, not after the search is completed. Post-search privilege claims fall under common law protection, potentially rendering evidence inadmissible under section 35(5) or affecting trial fairness. (Paras 186-190)
6. Allegations regarding complaints to JSC: The Court emphasized that alleged improper approaches by a High Court judge to influence Constitutional Court judges had no effect on consideration of these cases. The judicial process remained independent and fair, decided according to law without fear, favor or prejudice. (Paras 4-6)
MINORITY OBITER:
1. Graduated investigative mechanisms: The NPA Act provides three mechanisms of varying intrusiveness: (i) voluntary cooperation under s 29(10)(a)(i); (ii) section 28 summons with interrogation; (iii) search and seizure warrants. The legislature intended these to be used progressively, with more invasive means justified only when less invasive means are inadequate. This reflects the Act's concern for constitutional rights. (Paras 251-270)
2. Constitutional interpretation methodology: The "need" requirement must be construed to prevent unwarranted invasion of constitutional rights, consistent with section 39(2). The construction must not permit greater invasion than required to achieve the Act's objectives, while not making the Act unworkable. This requires striking a balance at the heart of limitation of rights analysis. (Paras 268-272)
3. Concerns about attitude toward suspects: The minority expressed concern that treating persons suspected of dishonesty offences as inherently untrustworthy contradicts constitutional values and risks creating a category of suspects with lesser rights. This approach could render section 28 superfluous if general distrust always justifies section 29 warrants. (Paras 366-379)
4. Importance of justification in constitutional democracy: In a constitutional state founded on justification rather than authority, the state must justify invasive conduct, especially when affecting constitutional rights. This is fundamental to preventing arbitrary exercise of power and essential when attorneys' offices are searched. (Paras 363, 380)
5. Role of judicial officers: The judicial officer issuing warrants is "the only line of pre-emptive defence" against unwarranted privacy invasions. This constitutional role can only be performed effectively with full and candid disclosure of all relevant facts, including those the target would rely on if able to oppose. (Paras 327, 380)
