1. Under the Employment Equity Act, where unfair discrimination is alleged on a listed ground (sections 6 and 11(1)), the employer bears the burden of proving either that discrimination did not occur or that it was justified. Where discrimination is alleged on an arbitrary ground (section 11(2)), the complainant bears the burden of proving the conduct was not rational, amounted to discrimination, and was unfair.
2. An employer's business and operational needs can constitute exceptional circumstances justifying differential treatment of employees and deviation from employment policies, but such needs must be demonstrated objectively and must be genuine and legitimate - they cannot simply be accepted on the employer's assertion.
3. Where comparator employees of the same protected characteristic (e.g., race) as the complainant receive similar differential treatment, this undermines claims that the protected characteristic was the basis for discrimination.
4. The test for both actual bias and reasonable apprehension of bias is whether "a reasonable, objective and informed person would, on the correct facts, reasonably apprehend bias." The threshold is high, and there is a presumption that judicial officers are impartial.
5. Allegations of bias must be raised timeously. A litigant who has full knowledge of facts supporting a bias claim but waits until after an adverse judgment to raise such allegations displays conduct inconsistent with a reasonable apprehension of bias and undermines the administration of justice. Such late-raised allegations will not be entertained.
6. A judge's previous professional or pecuniary association with a party, particularly one that ended years before the judge's appointment to the bench, does not give rise to a reasonable apprehension of bias unless the subject matter of the litigation arises from such associations or it can be shown that the association may reasonably be apprehended to obstruct the discharge of judicial duty.
7. In determining whether to grant leave to appeal under section 167(3) of the Constitution, the Court must be satisfied that the matter raises a constitutional issue or an arguable point of law of general public importance, and that it is in the interests of justice to grant leave. Prospects of success remain an important consideration in the interests of justice enquiry.
