#Key legal issues
#Whether the Tribunal erred in admitting the 2nd Respondent's Notice of Preliminary Objection filed out of time under Rule 9 NET Procedure Rules
The Tribunal properly exercised its discretion to admit the objection out of time, in line with Article 159(1)(d), and no prejudice was suffered by the Appellant who opposed it in submissions
The court applied Mbogo v Shah on non-interference with discretionary decisions. The Tribunal considered the Rule 9 timelines and its duty under Article 159(1)(d) to administer justice without undue regard to procedural technicalities. The Appellant had notice and opportunity to oppose the objection through submissions dated 25th August 2021, so no prejudice was suffered, and the objection was properly filed and admitted.
Whether the appeal fell under Section 129(1) or Section 129(2) of EMCA
The appeal fell under Section 129(1) EMCA; the 2015 amendment expanded locus standi so that any person aggrieved by the grant of a licence may appeal under Section 129(1), whether or not they participated in the licensing process
The court traced the three amendments to Section 129 and held the 2015 amendment changed the language of Section 129(1)(a) to expand standing to any person aggrieved by the grant of a licence, irrespective of participation. The court declined to follow Odunga J's narrower reading and distinguished the dual-stream approach in Simba Corporation and Prof Albert Mumma. Section 129(2) concerns other decisions not covered under Section 129(1).
Whether the preliminary objection raised factual disputations requiring evidence
The time-limitation objection was a pure issue of law and was rightly admitted for determination
From the pleadings the Appellant was not part of the licence issuance process, facts not contested, and the challenge concerned the grant of licence Ref NEMA/EIA/PSL/10439 dated 26th March 2021, making the appeal fall under Section 129(1) and rendering the limitation question a pure point of law determinable without evidence.
Legal principles established
#- An 'aggrieved person' under Section 129(1)(a) EMCA is not limited to persons who participated in the licensing process; all appeals with respect to licensing should be filed under Section 129(1) regardless of participation
- Section 129(2) EMCA deals with decisions of the Director-General, the Authority, Committees or agents not covered under Section 129(1), not with licensing decisions
- An appellate court will not interfere with the exercise of discretion by a trial court/tribunal unless the determination is clearly wrong or based on wrong principles
