Bristol City Council v A Mother & Ors

Bristol City Council v A Mother & Ors

The court declined to extend proceedings for further inquiry or detailed guidance, finding the discrepancy in hair-strand test results was due to human error, not scientific flaws, and that the four agreed propositions on hair-strand testing sufficed. Further inquiry or guidance would be unnecessary, disproportionate, and outside the court's remit.
