Mwangi v Republic (Criminal Appeal 73 of 1992) [2000] KECA 282 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a robbery conviction based only on indirect evidence, ruling that minor gaps in testimony don't defeat a strong case.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether a conviction based exclusively on circumstantial evidence could properly be upheld, i.e. whether the inculpatory facts were inconsistent with the appellant's innocence and whether there were co-existing circumstances weakening or destroying the inference of guilt.
- 2.Whether the discrepancies and gaps in the evidence (the number of rounds of ammunition, the serial number prefix, the dates and chain of custody of the firearm, and who recovered the expended cartridges) were so fundamental as to cause prejudice under section 382 CPC.
- 3.Whether the prosecution's failure to call Mr Kikwai, who personally delivered the firearm to the ballistics examiner, warranted an adverse inference against the prosecution under Bukenya v R.
- 4.Whether the trial magistrate was entitled to admit the appellant's inquiry statement notwithstanding that the record did not specifically show compliance with sections 210 and 211 of the Criminal Procedure Code, and whether that omission was curable under section 382 CPC.
- 5.Whether the Court of Appeal could, on a second appeal and suo motu, consider the propriety of the first appellate court's exclusion of the inquiry statement.
- 6.Whether the trial magistrate was right in declining to allow the prosecution to reopen its case and call rebuttal evidence at the end of the defence hearing during the trial within a trial.
- 7.Whether the appellant's possession of the firearm used in the robberies, recovered about 16 days after the robberies, was so recent as to justify the inference that he participated in them, and whether his explanation that he later stole the gun rebutted the presumption of participation.
Key legal issues
#Whether the conviction founded exclusively on circumstantial evidence met the Simon Musoke test
A conviction resting exclusively on circumstantial evidence can stand only where the inculpatory facts are inconsistent with innocence and no co-existing circumstances weaken or destroy the inference of guilt; the ballistic linkage of the murder weapon to the appellant's possession 16 days after the robberies, coupled with his confessed common purpose, satisfied that test.
The Court adopted the Simon Musoke test as the governing standard for convictions resting exclusively on circumstantial evidence. The ballistics expert's unchallenged opinion established that the rifle found on the appellant fired the cartridge cases and the bullet recovered from the robbery scenes. The only suggested co-existing circumstance was the appellant's claim that he stole the gun after the robberies, but his inquiry statement confessed to being party to the plan to rob, so the inference of participation was not weakened. Both courts below were entitled to draw it.
Whether the discrepancies in the evidence were fundamental or inconsequential under section 382 CPC
The discrepancies - the number of rounds, the serial number prefix, the dates of handling the firearm and who recovered the cartridge cases - were minute details, inconsequential under section 382 CPC because they caused the appellant no prejudice.
The Court held that trials inevitably attract discrepancies, especially where the offences occurred in May 1986 but the trial commenced a year later and restarted de novo over two years later after the first magistrate's elevation to the High Court. The governing test is whether discrepancies are so fundamental as to cause prejudice or are inconsequential to the conviction and sentence. The rifle's serial number tied it to the occurrence book entries and the ballistics examination, so the discrepancies were matters of minute detail that did not affect the tenor and substance of the prosecution case.
Whether the failure to call Mr Kikwai attracted the Bukenya adverse inference
The prosecution's failure to call Mr Kikwai, who delivered the firearm to the ballistics examiner, was of no consequence because the adverse inference arises only where the remaining evidence is barely adequate, which was not the case here.
The Court recited the Bukenya rule: where the prosecution fails to call a witness and the evidence supporting the charge is barely adequate, the court may infer that the witness's evidence would have been adverse to the prosecution. It declined to hold the evidence of possession barely adequate: the appellant admitted the arrest, the firearm's particulars were entered in the occurrence books at Ol Kalau and Nyahururu, his inquiry statement admitted possession, and PW14 testified to transmitting the firearm to the examiner. PW1 was simply mistaken about the date of handover.
Whether the inquiry statement was properly admitted despite the record not specifically showing compliance with sections 210 and 211 CPC
The trial magistrate was entitled to admit the inquiry statement; the record's failure to specifically state compliance with sections 210 and 211 CPC was a curable omission under section 382 CPC and caused the appellant no prejudice.
The first appellate court had held the trial within a trial a nullity because the record did not specifically show compliance with sections 210 and 211 of the Criminal Procedure Code. The Court of Appeal rejected that conclusion: the appellant gave sworn evidence in the trial within a trial, which he could not have done unless the court explained that he was at liberty to do so; the position would differ only had the record been silent on whether he testified. The omission was curable and the appellant, having testified, suffered no prejudice.
Whether the Court could raise, suo motu on second appeal, the propriety of the first appellate court's exclusion of the inquiry statement
A second appellate court may raise suo motu, as a point of law, the propriety of the first appellate court's exclusion of evidence supportable by the record, where the ends of justice so require.
Counsel for the appellant submitted the Court lacked jurisdiction to revisit the admissibility issue on second appeal, particularly as it had not been raised by either side and had been resolved in the appellant's favour below. The Court held that where a finding is supportable by evidence which was improperly excluded by the first appellate court, there is no impediment in law to considering the propriety of that exclusion; leaving such a finding to stand merely because it favoured the appellant would defeat the ends of justice.
Whether the trial magistrate was right to refuse to reopen the prosecution case after the defence hearing
The trial magistrate was quite right in declining to allow the prosecution to reopen its case and call rebuttal evidence at the end of the defence hearing during the trial within a trial.
The prosecutor's statement 'I have about 2 other witnesses' at the end of the defence hearing during the trial within a trial was not an explicit request to call rebuttal evidence on the allegation that the inquiry statement had been extorted. The Court held it unusual to reopen the prosecution case at the end of the defence hearing, the more so where the prosecution had closed after being given a hint that the admissibility of the statement would be challenged. The trial magistrate was therefore quite right to refuse.
Whether recent possession of the murder weapon, with a common purpose confessed, justified the inference of participation in the robberies
Possession of the murder weapon about 16 days after the robberies justified the inference of participation; the appellant's claim that he later stole the gun availed him nothing because he confessed to being party to the plan to rob, and he bore the duty to rebut the presumption of participation.
The rifle used in the attacks was found on the appellant on 27th May 1986, about 16 days after the robberies of 11th May 1986. The first appellate court considered that such a firearm does not easily change hands but failed to consider the appellant's explanation in his inquiry statement. The Court held that, since the statement confessed to being party to the plan to rob, it did not matter that only his accomplices executed the robbery: they had a common purpose and went out to execute it together. The appellant failed to rebut the presumption of participation.
Legal principles established
#- A conviction based exclusively on circumstantial evidence can only be upheld if the inculpatory facts are inconsistent with the innocence of the accused and there are no co-existing circumstances which would weaken or destroy the inference of guilt.
- In assessing discrepancies in the evidence, an appellate court must be guided by section 382 CPC, asking whether the discrepancies are so fundamental as to cause prejudice to the accused or are inconsequential to the conviction and sentence.
- Where the prosecution fails to call a witness and the evidence supporting the charge is barely adequate, the court trying the case is entitled to draw an adverse inference that the witness's evidence would have been adverse to the prosecution.
- An omission to specifically record compliance with sections 210 and 211 CPC in a trial within a trial is curable under section 382 CPC where the accused, having testified, suffers no prejudice.
- A second appellate court may properly raise suo motu, as a point of law, the propriety of the first appellate court's exclusion of evidence which is supportable by the record, where the ends of justice so require.
- It is unusual for a court to reopen the prosecution case at the end of the defence hearing to enable it to call further evidence.
- An accused who confesses to being party to a plan to rob is liable for the robbery committed by his accomplices in execution of that common purpose, and bears the duty to rebut the presumption of participation arising from recent possession of the murder weapon.
Court orders
#- 1.The appeal was dismissed in its entirety, upholding the convictions and sentences on all three counts (two counts of capital robbery contrary to section 296(2) and one count of simple robbery contrary to section 296(1) of the Penal Code).
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court (the superior court on first appeal)
- Jurisdiction invoked
- Second appeal to the Court of Appeal against conviction and sentence; the judgment does not expressly cite the jurisdictional provision, but the court exercises second-appeal jurisdiction over the first appellate court's decision and addresses its own limits in rejecting the submission that it lacked jurisdiction to entertain the admissibility issue.
Relief refused
#Allowance of the appeal against conviction and sentence on all three counts
The circumstantial evidence - the ballistic linkage of the murder weapon to the appellant's possession 16 days after the robberies, coupled with his confessed common purpose - satisfied the Simon Musoke test, and the discrepancies were inconsequential under section 382 CPC.
Exclusion of the ballistic and circumstantial evidence on account of the chain-of-custody gaps and the prosecution's failure to call Mr Kikwai
The discrepancy as to the date the firearm reached the ballistics examiner was not fundamental given the serial number and PW14's evidence of transmission, and the evidence of possession was not 'barely adequate', so no Bukenya adverse inference arose.
Costs
No order as to costs appears in the judgment; the judgment is silent on costs.
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
We find no co-existing circumstances to weaken or destroy the inference of the appellant's involvement and accordingly find no basis for interfering with his convictions and sentences in all the three counts and accordingly dismiss his appeal in its entirety.
the Court is satisfied that the inculpatory facts are not only inconsistent with the innocence of the appellant but also that there exists no co- existing circumstances which would weaken or destroy such inference.
An appellate court in considering those discrepancies must be guided by the wording of section 382 CPC, viz whether such discrepancies are so fundamental as to cause prejudice to the appellant or they are inconsequential to the conviction and sentence.
the Court trying the case is perfectly entitled to draw an adverse inference that had the witness testified his evidence would have tended to be adverse to the prosecution case.
the omission to specifically state that sections 210 and 211 CPC had been complied with is curable under the provisions of section 382 CPC. The appellant having testified cannot be said to have been prejudiced.
It is clearly a point of law which the Court can properly raise suo motu, for the ends of justice.
However, considering that in the statement he confesses to having been party to the plan to rob, it did not matter that only his accomplices participated in the intended robbery. They had a common purpose and together went out to execute it.
In the result we find that there is ample evidence upon which the concurrent findings of fact by both the courts below were based, that the appellant had possession of the firearm in issue on 27th May 1986, which firearm according to PW12 was the one which was used against PW3, her husband, and the fruit vendor, on 11th May, 1986.
Issues in the judgment
#Internal inconsistency on the time of the Ngarariga attack: the narrative states the victims stopped 'at about 5.30 pm' and were attacked before setting off, while the later analysis states 'We earlier stated that PW 3, her late husband and the fruit vendor were attacked at about 5.20 pm on 11th May 1986'.
The second robbery victim is named 'Joseph Kamau Kiburu' on first mention but 'Joseph Kamau Kaburu (PW10)' in the narrative thereafter.
Exhibit numbering is inconsistent: the paper bag recovered from the appellant is earlier described as 'exhibit 8', yet the same number is later assigned with 'respectively' to the sunglasses found on a companion.
