Apparent Bias

Apparent bias is present where a judge or other decision-maker is not a party to a matter and does not have an interest in its outcome, but through his or her conduct or behaviour gives rise to a suspicion that he or she is not impartial. An issue that has arisen is the degree of suspicion which would provide the grounds on which a decision should be set aside for apparent bias. Currently, cases from various jurisdictions apply two different tests: "real likelihood of bias" and "reasonable suspicion of bias".

The real likelihood test centres on whether the facts, as assessed by the court, give rise to a real likelihood of bias. In R. v. Gough (1993), the House of Lords chose to state the test in terms of a "real danger of bias", and emphasized that the test was concerned with the possibility, not probability, of bias. Lord Goff of Chievely also stated that "the court should look at the matter through the eyes of a reasonable man, because the court in cases such as these personifies the reasonable man". However, the test in Gough has been disapproved of in some Commonwealth jurisdictions. One criticism is that the emphasis on the court's view of the facts gives insufficient emphasis to the perception of the public. These criticisms were addressed by the House of Lords in Porter v. Magill (2001). The Court adjusted the Gough test by stating it to be "whether the fair-minded and informed observer, having considered the facts, would conclude that there was a real possibility that the tribunal was biased". This case therefore established the current test in the UK to be one of a "real possibility of bias".

On the other hand, the reasonable suspicion test asks whether a reasonable and fair-minded person sitting in court and knowing all the relevant facts would have a reasonable suspicion that a fair trial for the litigant is not possible. Although not currently adopted in the UK, this test has been endorsed by the Singapore courts.

It has been suggested that the differences between the two tests are largely semantic and that the two tests operate similarly. In Locabail, the judges stated that in a large proportion of the cases, application of the two tests would lead to the same outcome. It was also held that "rovided that the court, personifying the reasonable man, takes an approach which is based on broad common sense, and without inappropriate reliance on special knowledge, the minutiae of court procedure or other matters outside the ken of the ordinary, reasonably well-informed members of the public, there should be no risk that the courts will not ensure both that justice is done and that it is perceived by the public to be done". In the Singapore High Court decision Tang Kin Hwa v. Traditional Chinese Medicine Practitioners Board (2005), Judicial Commissioner Andrew Phang observed that the real likelihood test is in reality similar to that of reasonable suspicion. First, likelihood is in fact "possibility", as opposed to the higher standard of proof centring on "probability". Secondly, he suggested that real in real likelihood cannot be taken to mean "actual", as this test relates to apparent and not actual bias. He also observed that both the court's and the public's perspectives are "integral parts of a holistic process" with no need to draw a sharp distinction between them.

In contrast, in Re Shankar Alan s/o Anat Kulkarni (2006), Judicial Commissioner Sundaresh Menon thought that there was a real difference between the reasonable suspicion and real likelihood tests. In his opinion, suspicion suggests a belief that something that may not be provable could still be possible. Reasonable suggests that the belief cannot be fanciful. Here the issue is whether it is reasonable for the one to harbour the suspicions in the circumstances even though the suspicious behaviour could be innocent. On the other hand, likelihood points towards something being likely, and real suggests that this must be substantial rather than imagined. Here, then, the inquiry is directed more towards the actor than the observer. The issue is the degree to which a particular event is not likely or possible. Menon J.C. also disagreed with both Lord Goff in Gough and Phang J.C. in Tang Kin Hwa in that he thought the shift of the inquiry from how the matter might appear to a reasonable man to whether the judge thinks there is a sufficient possibility of bias was "a very significant point of departure". The real likelihood test is met as long as the court is satisfied that there is a sufficient degree of possibility of bias. Although this a lower standard than satisfaction on a balance of probabilities, this is actually directed at mitigating the sheer difficulty of proving actual bias, especially given its insidious and often subconscious nature. The reasonable suspicion test, however, is met if the court is satisfied that a reasonable member of the public could harbour a reasonable suspicion of bias even though the court itself thought there was no real danger of this on the facts. The difference is that the driver behind this test is the strong public interest in ensuring public confidence in the administration of justice. As of September 2011, the Court of Appeal of Singapore had not yet expressed a view as to whether the position taken in Tang Kin Hwa or Shankar Alan is preferable.
