The Tribunal made several important obiter observations:
1. Section 41 of the National Water Act is not mandatory in all circumstances. The use of "may" accords considerable discretion to the responsible authority to determine whether public participation processes are required, coupled with a duty to conduct such processes "in a proper case."
2. Rule 12 of the Water Tribunal Rules on subpoenas applies only to subpoenaing witnesses and evidence in preparation for hearing a valid appeal already properly before the Tribunal. It cannot be used by a person seeking to validate their standing to lodge an appeal in the first place.
3. The Tribunal has no jurisdiction to adjudicate or provide remedies under NEMA, PAJA, or PAIA. Appellants cannot use the section 148 appeal process to obtain information and reasons for a decision from the responsible authority that should have been sought through other statutory mechanisms.
4. Although the procedural issues raised were important for clarifying participatory rights and procedural fairness, and the matter had practical effect on similarly situated persons, these issues could not be determined because the appellants lacked standing. The interests of justice favored clarifying the extent of the class of persons with locus standi.
5. The matter was not moot despite the expiry of the three-year WUL, because the determination had practical effect on persons similarly situated who intended to or had already lodged appeals without having lodged prior objections.
