A constitutional petition can fail before a judge ever decides whether a right was actually violated. That is the practical lesson behind Anarita Karimi Njeru v Republic, a 1979 High Court decision that has survived a complete change of constitutional order and still appears in Kenyan rights litigation. The legal question is deceptively simple: how clearly must a person explain a constitutional complaint before a court and the opposing party can fairly deal with it? The answer is not that every petition must be drafted like a perfect textbook pleading. It is that a constitutional case must show a workable connection between the facts, the right said to be infringed, the person said to have infringed it, the injury, and the remedy being requested.

The case behind the pleading rule

Anarita Karimi Njeru had been the headmistress of St Mary’s Girls’ Secondary School at Egoji in Meru. She was convicted before a Resident Magistrate on charges of stealing by a person employed in the public service. During the defence case, her lawyers wanted to call Richard Francis Mase, an accountant connected with the firm that had audited the school’s accounts. A witness summons was issued only after the defence had been called, it was returned unserved, and the magistrate declined to adjourn the proceedings for another attempt to secure the witness. Njeru later asked the High Court for constitutional redress, relying on the fair-trial guarantees in section 77 of Kenya’s former Constitution.

The litigation therefore involved more than pleading style. Trevelyan and Hancox JJ considered whether the constitutional procedure could be used after another judicial route had already been pursued, whether refusal of the adjournment had denied the accused reasonable facilities to secure a defence witness, and whether the constitutional complaint had been stated with sufficient particularity. The court upheld a preliminary objection connected with the earlier proceedings and also found no fair-trial violation on the witness issue. That history matters because Anarita is sometimes reduced to a single sentence about precision, as if vagueness alone decided the case. It did not.

What “reasonable precision” actually requires

The lasting principle is that a constitutional claimant should identify, with a reasonable degree of precision, the complaint, the constitutional provision said to be infringed, and the manner in which the complained-of conduct produced that infringement. In practical terms, a petition should let a reader understand who did what, which constitutional protection is engaged, why those facts amount to a violation or credible threat, what injury followed or is likely to follow, and what order the court is being asked to make. A long list of constitutional articles is not a substitute for that chain of reasoning.

That rule protects both sides. A public officer accused of violating Article 47 of the Constitution, for example, needs to know whether the complaint concerns lack of notice, refusal of a hearing, absence of reasons, bias, irrationality, or some other defect. Those are not interchangeable allegations. They may require different records, witnesses, explanations and remedies. Precision therefore serves fair notice and efficient adjudication rather than judicial preference for elegant drafting.

The 2010 Constitution softened formalism, not clarity

Modern Kenyan constitutional procedure makes it important to read Anarita together with the Constitution of Kenya 2010 and later authority. Article 22 gives broad standing to enforce the Bill of Rights and requires procedural formalities to be kept to a minimum. Article 159(2)(d) directs courts to administer justice without undue regard to procedural technicalities. Those provisions do not abolish the need to define a dispute. They prevent the precision requirement from turning into an obstacle course of empty formality.

The Court of Appeal made that balance explicit in Matemu v Trusted Society of Human Rights Alliance & 5 others [2013] KECA 445 (KLR). It reaffirmed Anarita but stressed that precision is not the same as exactitude. Pleadings are supposed to give fair notice and identify the controversy; they need not contain a formulaic recital of every fact or a ritual quotation of constitutional text. Where a pleading is curably deficient, amendment may be more consistent with substantive justice than treating every omission as fatal.

Rule 10 turns the principle into a filing discipline

The Constitution of Kenya (Protection of Rights and Fundamental Freedoms) Practice and Procedure Rules, 2013, commonly called the Mutunga Rules, give advocates and self-represented litigants a practical framework. Rule 10 requires a petition to disclose the facts relied on, the constitutional provision violated, the injury caused or likely to be caused, details of related civil or criminal cases, and the relief sought, alongside the required party and signature information. That structure closely reflects what Anarita is trying to achieve: a court should not have to reconstruct the constitutional theory from scattered facts and submissions.

A useful drafting method is to treat each alleged violation as its own complete proposition. If three respondents are sued, the petition should distinguish what each one is alleged to have done. If several rights are invoked, the pleading should explain the factual route to each important right rather than attaching every conceivable constitutional article. If earlier proceedings exist, their relationship to the petition should be disclosed so that jurisdiction, res judicata, abuse of process or alternative-remedy issues are confronted openly. Evidence can develop later, but the theory of the case should not first emerge during final submissions.

Why the rule remains current in 2026

The Anarita principle is not a museum piece from the former Constitution. In Katiba Institute v Attorney General & 2 others; Ndii & 20 others (Interested Parties) [2026] KEHC 258 (KLR), the High Court again treated reasonable precision as part of the fairness of constitutional adjudication. The court asked whether the impugned conduct and constitutional provisions were identified with sufficient specificity as against each respondent. That continuing use is important because it shows that the modern question is functional: could the respondent understand the case and could the court fairly determine it?

For an ordinary person entering court, this changes how a grievance should be organised. A statement such as “the government violated my constitutional rights” is a starting complaint, not yet a complete constitutional case. The useful next questions are concrete. What decision, omission, arrest, notice, refusal or regulation is being challenged? Who is legally responsible for it? What right or constitutional duty does that conduct engage? How did the conduct cause the alleged injury? Which remedy would correct or prevent it? Answers to those questions usually make a petition clearer than adding more constitutional provisions.

What courts and lawyers should avoid

Anarita can be misused in two opposite ways. One is to ignore vagueness and allow a party to shift its constitutional theory throughout the case, leaving the respondent to answer a moving target. The other is to weaponise the precedent against a litigant who has plainly identified the dispute but has not used ideal legal language. Matemu and Article 22 point away from both extremes. The proper inquiry is whether the claim is sufficiently intelligible for fair notice, proof, response and adjudication.

That also means a court should distinguish pleading from proof. A petition may clearly allege that a named officer denied a hearing before cancelling a licence, yet still fail because the evidence does not prove the denial. Conversely, strong evidence cannot always rescue a petition that never told the respondent that denial of a hearing was the constitutional complaint. Pleading and proof perform different jobs, and Anarita is principally about the first.

Why Anarita matters beyond lawyers

The case matters because constitutional litigation is a form of public accountability. Clear pleadings help judges identify the real constitutional question, help public bodies explain their conduct, reduce surprise, and make remedies more accurately fit the proven violation. They also make judgments easier for the public to understand. A reader should be able to see why a particular fact engages a particular constitutional protection and why the court granted or refused a particular order.

The enduring value of Anarita is therefore not a demand for technical perfection. It is a discipline of connection. Under the 2010 Constitution, the claimant should be given meaningful access to constitutional justice, but the respondent is equally entitled to know the case being answered. Read with Matemu, the Mutunga Rules and Articles 22 and 159, the case asks for enough precision to make constitutional justice possible, not enough technicality to keep people out of court.
