Shawn Campbell and 3 Others v The King (No 2) (Jamaica)
Why It Matters
The decision will set a precedent for how Jamaican courts handle charter‑breached digital evidence and jury integrity, influencing future prosecutions and defendants’ rights.
Key Takeaways
- •Juror Kaine convicted of attempting to pervert justice via bribery.
- •JS2 evidence obtained in breach of Jamaican Charter, raising admissibility concerns.
- •Texts from Campbell incriminate him before and after the murder.
- •Crown argues JS2 justifies applying PROVO to dismiss the jury.
- •Cell‑site data minimally addressed, limiting its evidentiary impact.
Summary
The Jamaican Supreme Court heard the appeal of Shawn Campbell and four co‑defendants against the Crown, focusing on whether key digital evidence – labelled JS2 – should be admitted after a statutory breach, and whether the jury should be discharged under the PROVO doctrine.
The hearing highlighted several pivotal points: juror Mr Kaine was convicted of attempting to pervert the course of justice through a bribery scheme; JS2 was extracted in violation of section 16 of the Jamaican Charter, prompting a debate over its exclusion; incriminating text messages from Campbell surrounding the August 2011 killing were identified as the only materially harmful content; cell‑site analysis was presented but received scant judicial commentary; and the Crown contended that the tainted JS2 justified invoking PROVO to nullify the jury’s verdict.
Counsel repeatedly cited the Putnam precedent, warning that “the longer the poison has been circulating, the harder it is to produce a fair trial,” and underscored the uncertainty about how long the alleged contamination persisted. References to specific appellate paragraphs (e.g., 155, 5827, 24) were used to locate the raw data and its interpretive spreadsheets, illustrating the procedural complexity of the evidence chain.
The outcome will shape Jamaican criminal procedure by clarifying the limits of charter‑compliant digital forensics and the thresholds for jury disruption. A ruling favoring exclusion could tighten evidentiary safeguards, while affirmation of PROVO would signal a broader willingness to overturn verdicts when procedural integrity is compromised.
