This is the trial judge's comprehensive written judgment recording primary facts and findings in the case.

The Court reviewed and summarised the trial judge's factual findings and the strands of circumstantial evidence recorded in that judgment.

Test for appellate review in criminal cases: whether the verdict is unsafe and the correct approach to appellate scrutiny.

The Court applied the Pollock safety test as the overarching question in reviewing the convictions.

Reiteration and clarification of the Pollock safety test.

The Court cited Duffy to reinforce that the correct test is whether convictions are safe.

Guidance on appellate approach in non‑jury (judge alone) trials and the judge's task in giving reasons.

The Court applied the principles to emphasise deference to primary fact findings but retained appellate scrutiny of inferences and legal direction.

Authority cited for general proposition on judge's obligations in trials without jury (as referenced in Murray).

Used to support the proposition that a judge must give reasons and notice difficult points of law.

Source for four appellate principles applicable to non‑jury trials.

The Court applied the four Thain principles (deference to primary facts; appellate parity on inferences from documents; reversal if misdirection; avoid conjecture).

Referenced in context of the Thain principles.

Supported the summary of appellate principles for judge‑alone trials.

Discusses effect of defective or erroneous findings in Diplock/non‑jury judgments.

Used to consider whether any erroneous findings undermined the safety of the convictions.

Principle on defective findings: whether the judge would inevitably have convicted absent errors.

Invoked as part of the analysis whether errors (if any) would have been decisive.

Related authority on assessing effects of erroneous findings in non‑jury judgments.

Referenced to assist in evaluating any potentially defective findings.

Principle that appellate court must be satisfied the remaining evidence would inevitably have led to conviction if misdirection occurred.

Cited to frame the Court's approach to alleged misdirections and whether they undermined convictions.

Authority on using vehicle and movement evidence in circumstantial cases.

Used to support the restrained, contextual use of vehicle movements and timing as corroborative strands.

Recent non‑jury authority relevant to appellate approach.

Applied as part of the appellate framework; no specific novel rule extracted beyond general approach.

Discusses circumstantial evidence and how juries (and by analogy judges) should approach competing inferences.

Applied to reiterate that circumstantial strands must be assessed together and that alternative innocent inferences must be excluded to convict.

Principles on drawing inferences from circumstantial evidence.

Quoted to emphasise common‑sense approach to competing inferences from single pieces of evidence.

Authority on strands of circumstantial evidence forming a cumulative case.

Used to reject submission that weak strands should be ignored where cumulatively they are probative.

Classic statement on circumstantial evidence as a rope of several cords.

Applied to justify holistic assessment of multiple evidential strands.

Application of Galbraith no‑case test in circumstantial contexts.

Cited for guidance that a reasonable tribunal could draw adverse inferences on one possible view of the evidence.

Discusses appellate flexibility in reviewing inferences drawn by first instance courts.

Noted to reinforce scope for appellate intervention where inferences are found to be wrong.

Principle that discharge/recusal of a jury is exceptional.

Referred to in the context of recusal; supported restrained approach to discharge/recusal.

Authority where a judge refused to recuse despite exposure to potentially prejudicial material.

Applied to support trial judge's refusal to recuse where risk was manageable by judicial awareness and impartiality.

Quoted for the proposition that judges can compartmentalise and avoid subconscious influence.

Relied upon in the recusal analysis and to support continuation of the trial judge.

Approach to exposure of prejudicial material and discharge/recusal discretion.

Followed (via Ghadghidi/Arthurton line) to assess whether the judge's impartiality was compromised.

Line of authority on exposure to prejudicial material and discharge criteria.

Applied as part of the recusal analysis.

Privy Council authority on trial exposure to prejudicial material and whether juries/tribunals should be discharged.

Applied to frame the discretionary approach to recusal/discharge.

Principles on admissibility of bad character/background evidence, particularly in gang/motive contexts.

Relied upon to justify admission of prior incidents as relevant motive/background evidence.

Admissibility of previous gang violence as evidence of motive; rejects temporal limitation.

Used to support admission of background incidents irrespective of temporal gap.

Confirms previous violent incidents are admissible when directly relevant to alleged facts (motive/identity).

Applied to validate admission of background material as relevant to motive and identity.

Further application of background/motive principles in multi‑defendant cases.

Referenced to support the judge's admission and circumscribed use of background evidence.

Use of telephony/cell evidence for timing, association and sequencing rather than as standalone proof.

Cited to justify the judge's restrained use of telephony as chronological and associational, not conclusive.

Similar proposition on cautious deployment of telephony evidence.

Used to support the trial judge's approach.

Principles on assessing inferential material and cumulative strands in circumstantial cases.

Applied to emphasise holistic assessment of strands rather than isolated scrutiny.

Sequencing, movement and opportunity evidence can support cumulative inferences.

Relied upon to justify using movement/sequence evidence as corroborative context.

This citation appears in the judgment in the context of vehicle movement evidence; the precise rule was not elaborated.

The Court noted that vehicle movement evidence, when integrated with timing and association, can be corroborative; the judge's use was proportionate.

Principles on bad character evidence and narrative integrity.

Used to support a balanced admission of contextual bad character material while excluding more prejudicial matters.

Guideline authority on murder tariffs and starting points for minimum terms.

The judge applied Whitla to place this case in a higher starting point category (20 years) given aggravating features; the Court upheld that application.

Discusses upward adjustment of the starting point in sentencing.

Cited for the proposition that significant aggravating factors may justify substantial upward adjustment.

Guidance on reductions for guilty pleas in murder cases and related sentencing matters.

Applied to determine appropriate reduction for late guilty pleas (court accepted a two and a half year reduction for Appellants D and E).

Earlier guideline on murder tariffs recalibrated by Whitla.

Referenced to situate Whitla and sentencing approach in historical context.

Discusses whether intention to cause grievous bodily harm (GBH) rather than to kill operates as mitigation.

Applied to explain that lesser intent is fact‑sensitive and may not materially mitigate where violence is gratuitous or extensive.

Authority on extent of mitigation from lack of intention to kill.

Cited to emphasise that absence of intent to kill does not automatically yield significant mitigation.

Addressed reduction for delay and that any reduction should attach equally to all offenders.

Invoked; the Court applied the principle and found no culpable delay warranting reduction in this complex, non‑cooperative case.

Principles on delay and sentence reduction.

Applied with McGinley to reject allowance for delay on the facts.

The sentencing ruling by the trial judge in this case (reported separately).

The Court reviewed that sentencing judgment and upheld the chosen tariffs after considering aggravation and mitigation.
