Arbitration analysis: This case deals with the challenge of a sole arbitrator on the ground of apparent bias pursuant to section 24(1)(a) of the English Arbitration Act 1996 (the ‘Act’) in the film industry. Applying the test laid down in the landmark ruling of Haliburton, the court found that the arbitrator’s actions would lead a fair-minded and informed observer to conclude that there was a real possibility that the arbitrator was biased. Following Haliburton, the court’s approach in the present case serves as an illustration par excellence of factual circumstances that may give rise to the successful invocation of apparent bias within the meaning of the Act. Notably, the enquiry into apparent bias is fact-driven and, as such, will differ on a case-by-case basis. The ruling is of interest to arbitrators more generally but, in particular, to those who arbitrate in niche industries more specifically as these tend to give rise to the type of circumstances, such as professional acquaintanceship, from which situations of apparent bias that qualify for a successful challenge under section 24 may readily arise.
