Gnango, R v

Factual and Procedural Background

The Defendant, aged 17 at the time, and an unidentified gunman (“Individual B”) became embroiled in a pre-arranged or spontaneous gun-fight on a residential estate in The City. During an exchange of fire, a passer-by (“Victim”) was struck and fatally injured by a bullet fired from Individual B’s weapon. Scientific evidence excluded the Defendant’s gun as the source of the fatal round.

Both shooters fled. Individual B was never charged; the Defendant was arrested four days later. At trial in the Crown Court the Defendant was convicted of Victim’s murder on the basis of directions founded on “parasitic accessory liability”. The Court of Appeal quashed the conviction, holding that the directions were unsustainable. The Supreme Court granted permission to appeal to resolve a certified question of general public importance concerning liability where two parties intentionally fight with lethal intent and an innocent third person is killed.

Legal Issues Presented

1. Whether, and in what circumstances, a combatant (D2) is guilty of murder when his opponent (D1), intending to kill or cause grievous bodily harm to D2, mistakenly kills a bystander.
2. The compatibility of three common-law doctrines—joint enterprise (“parasitic accessory liability”), transferred malice, and the “victim rule”—with the facts of a mutual gun-fight.
3. Whether the Court of Appeal erred in holding that no joint enterprise existed because each gunman’s intent was “equal and opposite”.

Arguments of the Parties

Prosecution’s Arguments

• The Defendant and Individual B jointly embarked on an affray involving firearms; the Defendant foresaw that Individual B might shoot with murderous intent, thus satisfying parasitic accessory liability for Victim’s murder.
• Alternatively, by agreeing to a duel-like shoot-out, the Defendant aided and abetted Individual B’s attempt on his life; under transferred malice, that secondary participation makes him liable for Victim’s death.
• The common-law “victim rule” (derived from R v Tyrrell) does not bar liability because the rule is confined to protective offences and does not extend to violent crimes such as murder.

Defence’s Arguments

• There was no joint enterprise: each shooter pursued a personal, antagonistic purpose to kill the other; reciprocal intent cannot amount to a shared common purpose.
• The Defendant could not aid and abet his own attempted murder; therefore any doctrine relying on secondary participation must fail.
• Even if an affray was jointly committed, treating it as the springboard for murder would impermissibly expand parasitic accessory liability and create unjust policy consequences for spontaneous public-order violence.

Court's Reasoning and Analysis

The majority held that the Court of Appeal had misconstrued joint enterprise principles. On the facts the only realistic inference was that both gunmen consciously agreed—either pre-arranged or instantly—to engage in a lethal shoot-out in a public place. That mutual agreement rendered each participant liable for:

• Attempted murder of his opponent; and therefore
• The actual murder of Victim via the doctrine of transferred malice.

The Court rejected the argument that a person cannot be an accessory to his own attempted murder. The “victim rule”, limited to protective offences, did not apply to violent crimes such as murder. Further, because the combat was consensual (analogous to a duel), each shooter’s conduct necessarily encouraged the other to fire; thus, whether characterised as a principal in a joint enterprise or as an accessory via aiding and abetting, the Defendant’s liability was established.

The court also dismissed reliance on “parasitic accessory liability” based solely on the statutory offence of affray, deeming it artificial to separate the intention to commit affray from the homicidal intent inherent in a gun-fight. Ultimately, the jury’s guilty verdict could stand because the directions, though framed in affray terms, required the jury to be sure there was a plan to “have a gun-fight” with intent to kill or cause grievous bodily harm—criteria sufficient to fix the Defendant with liability for murder.

Holding and Implications

Appeal allowed; conviction for murder restored.

By answering the certified question affirmatively, the Supreme Court confirmed that a combatant may be convicted of murder where his opponent kills an innocent bystander in a mutually intentional, lethal confrontation. The decision clarifies that the “victim rule” does not shield participants in violent crimes and that transferred malice applies equally to principals and accessories engaged in planned deadly violence. While the judgment leaves open broader policy issues involving group disorder, it establishes that those who willingly participate in public gunfights assume liability for foreseeable fatal outcomes, regardless of whose bullet strikes the victim.
