Arbitration analysis: Mr Michael Green QC, sitting as a Deputy Judge of the Chancery Division, dismissed a serious irregularity challenge, made pursuant to section 68 of the Arbitration Act 1996 (AA 1996), against an award of the Beth Din of the Federation of Synagogues in London (the Beth Din). The claimant unsuccessfully alleged apparent bias on the part of the 'Rosh' or Head of the Beth Din. In dismissing the challenge, the court, among other matters, relied on the decision of the Court of Appeal in Halliburton Company v Chubb Bermuda Insurance Ltd, which has been appealed to the Supreme Court and the judgment is awaited.
