The court expressed important obiter regarding Rule 67A of the Uniform Rules of Court: 1. The court respectfully disagreed with Mashavha v Minister of Police regarding Rule 67A's retrospective application, suggesting that the rule affects adjectival/procedural rather than substantive rights. 2. No vested rights exist regarding party and party costs until the court makes its costs order - prior to that there is only a spes or legitimate expectation. 3. Rule 67A does not change the maximum recoverable amount (R4,500/hour under Scale C, same as the previous regime), so no substantive rights are affected. 4. The change in who determines the scale (from taxing master to judge) is procedural, and under Unitrans principles, the new procedure applies when the court is asked to determine the scale, regardless of when costs were incurred. 5. If attorney and client costs had not been awarded, the court would have granted costs on Scale C throughout, given the complexity, importance of constitutional environmental rights, engagement of senior counsel by both sides, specialized knowledge required, and public interest nature of the case. 6. The court noted difficulties with the subjective vs objective test for determining importance under Rule 67A, and suggested that the taxing master's discretion within the scale set by the court remains unchanged. 7. The court emphasized that NEMA's streamlined private prosecution provisions (not requiring a nolle prosequi) reflect the legislature's recognition of the State's inability to prosecute all environmental offenders and the constitutional importance of environmental protection for present and future generations.
