IEBC’s Playbook for Repeat Litigation

Public institutions with a broad statutory mandate (electoral bodies, regulators, revenue authorities) face a particular kind of litigation risk: the same legal question, dressed up in new facts, arriving again and again. A recent High Court decision shows how a well-settled precedent, properly invoked, can shut that kind of challenge down efficiently, without the institution having to relitigate the merits from scratch each time.

The Case, Briefly

In Mwenda Johnstone Gichuru v IEBC & 2 Others (High Court at Meru, Petition No. E015 of 2022), a university lecturer resigned from his post to contest the position of Speaker of the Meru County Assembly, but did so less than six months before the general election, short of the resignation deadline required under Section 43(5) of the Elections Act for public officers seeking elective office. The Independent Electoral and Boundaries Commission declined to clear him as a candidate on that basis.

The petitioner challenged that refusal in the High Court, arguing that the six-month rule made no logical sense for a Speaker election, since the Speaker vacancy only arises after the general election is over, meaning, in his view, there was no way to know six months in advance when to resign.

C.B. Mwongela & Co. Advocates, acting for IEBC, didn’t need to re-argue the underlying policy merits of the six-month rule at all. Instead, the firm’s position (accepted in full by the Court) was that the constitutionality of Section 43(5) had already been conclusively decided by the Court of Appeal in earlier litigation, and that the petitioner’s argument was simply the same settled question wearing a different set of facts. The High Court agreed, dismissed the petition entirely as barred by res judicata, and awarded costs to IEBC.

Why This Approach Works

For an institution like IEBC, which administers the same statutory framework across hundreds of elections and thousands of candidates, the risk isn’t just losing one case, it’s the prospect of every disappointed candidate independently re-litigating the same constitutional question, indefinitely, each dressed in slightly different facts. If courts entertained each of those challenges on the merits from zero, institutional litigation costs and legal uncertainty would compound without limit.

Res judicata exists precisely to prevent that. Once a matter has been directly and substantially decided by a competent court, the same issue (even between different parties, in a different factual setting) does not need to be re-litigated. Raising this defence early and well means an institution doesn’t have to re-win an argument it has already won.

The skill in this kind of case isn’t complex advocacy on the substantive law, it’s recognising, quickly and precisely, that a “new” challenge is in fact an old one, and marshalling the prior authority cleanly enough that the court doesn’t need to look past the preliminary point at all.

The Takeaway for Institutional Clients

For government agencies, statutory commissions, and regulators that face structurally repetitive litigation (the same class of decision challenged over and over by different aggrieved parties) this case is a reminder that:

Tracking your own litigation history and the appellate precedent it has generated is a genuine institutional asset, not just a filing exercise;

A res judicata or precedent-based defence, raised early and precisely, can dispose of a case before it consumes significant institutional resources; and

Counsel who know an institution’s litigation history well are able to spot these patterns faster than counsel encountering the matter for the first time.
