The bottom line

#

Kenya's Court of Appeal confirmed that an unqualified prosecutor's part in a trial taints only that portion, not the entire trial.

What this practically means

#

Executive summary

#
The Court of Appeal (Bosire, Githinji & Aganyanya JJ.A) dismissed in its entirety a second appeal by Peter Kihia Mwaniki against his conviction for robbery with violence contrary to section 296(2) of the Penal Code and the resulting sentence, affirming the decisions of the trial magistrate's court and the High Court on first appeal (Lesiit & Makhandia, JJ.). The appellant, a gardener, contended he was kidnapped by robbers who raided his employer's New Muthaiga home on 24th August 2001, but eye witnesses Hansa Bakrania and houseboy John Irungu Wachira testified that he actively participated — leading the robbers through the house, taking room keys, changing clothes, tying up the houseboy and leaving with them wearing a stolen leather jacket. On the procedural grounds: the court held that although a police corporal below the rank of Assistant Inspector had improperly prosecuted part of the trial contrary to section 85(2) of the Criminal Procedure Code, that invalidity did not vitiate the entire trial; only the evidence of the fourth prosecution witness was expunged, and the remaining evidence sufficed to sustain the conviction. Failure to produce the motor vehicle and the appellant's clothes as exhibits was held not fatal. The constitutional complaint of detention beyond 14 days before presentation to court under section 72(3)(b) of the former Constitution failed because the point was raised for the first time on second appeal, denying the prosecution a chance to explain the delay, and the 14-day period is not absolute. This judgment now binds subordinate courts on the partial-nullity rule and the treatment of late-raised constitutional delay objections.

Questions the Court framed

#

The issues the Court set itself to decide, in its own words.

  1. 1.Whether prosecution of part of the case by a police officer below the rank of Assistant Inspector of Police (Cpl. Osiemo) rendered the entire trial a nullity
  2. 2.Whether the appellant was a participant in the robbery or merely a victim of kidnapping
  3. 3.Whether the two courts below adequately considered the appellant's defence
  4. 4.Whether failure to tender essential exhibits (the motor vehicle and the appellant's clothes) was fatal to the prosecution case
  5. 5.Whether the delay of over 14 days in presenting the appellant to court after arrest violated section 72(3)(b) of the former Constitution

Key legal issues

#
01

Effect of prosecution by an unqualified police officer

Holding

Participation of Cpl. Osiemo, who was not qualified under section 85(2) CPC, did not render the whole trial a nullity; only the evidence he led was expunged and the rest of the proceedings were valid.

Reasoning

Following Elirema, proceedings conducted by a person below the rank of Assistant Inspector are a nullity, but that nullity attaches only to the portion of the trial he conducted. The court adopted the respondent's submission that the fourth witness's evidence could be expunged without affecting the rest, in the interests of justice, and then tested the remaining evidence for sufficiency.

p. 2
02

Whether the appellant was a participant or a victim

Holding

The eye-witness evidence of Hansa and Wachira established that the appellant voluntarily participated in the robbery; his defence of kidnapping was rejected.

Reasoning

Witnesses saw the appellant leading robbers through the house, taking room keys, changing clothes, tying up the houseboy and leaving with the robbers wearing a stolen leather jacket. Circumstantial indicators — opening the gate on the pretext of taking out garbage, the dogs being locked up, and the jacket recovered with him — corroborated participation. His surrender was a ruse motivated by pressure from relatives and police interest.

p. 3
03

Adequacy of consideration of the defence

Holding

Both courts below considered and properly rejected the appellant's defence; the ground had no merit.

Reasoning

The trial magistrate reviewed the eye-witness accounts and made explicit findings that the appellant was positively identified during a daytime robbery and that his kidnapping defence was untrue. The first appellate court considered the same evidence and reached the same conclusion, so the complaint of inadequate consideration failed.

p. 4
04

Non-production of exhibits

Holding

Failure to avail the motor vehicle and the appellant's clothes was not fatal; more incriminating exhibits were produced and no failure of justice arose.

Reasoning

Although it would have been proper to avail the exhibits, the omission was not fatal because other, more incriminating exhibits were tendered and the eye-witness testimony independently established guilt.

p. 4
05

Delay in presentation to court after arrest

Holding

The constitutional complaint under section 72(3)(b) of the former Constitution failed because the issue was raised for the first time on second appeal, denying the prosecution the opportunity to explain the delay.

Reasoning

The appellant was arrested on 1st September 2001 and presented on 11th October 2001, beyond 14 days, but the issue was never raised at trial or on first appeal where evidence on the delay could have been called. The 14-day period is not absolute and the burden of explanation falls on the party alleging the delay was justified.

p. 4

Legal principles established

#
  • Where an unqualified police prosecutor below the rank of Assistant Inspector conducts only part of a trial, the invalidity affects only the proceedings conducted during his participation and does not extend to what was done according to law; the offending evidence may simply be expunged.
  • Failure to produce an essential exhibit is not fatal to a prosecution case where other incriminating exhibits were produced and no failure of justice arose.
  • The 14-day time frame for presenting an arrested person to court under section 72(3)(b) of the former Constitution is not absolute, and a person who alleges a breach must raise it at trial so the prosecution can explain the delay.

The invalidity of what he did may only properly affect the proceedings relating to the time he prosecuted. In our view the invalidity should not extend to what was done according to law.
