444.Under previous legislation, in most cases the burden of proof was reversed once the claimant had established a case to an initial level. However, the burden of proof was not previously reversed in race discrimination claims brought because of colour and nationality; claims of victimisation which related to race discrimination; non-work disability discrimination claims; and sex discrimination claims which related to the exercise of public functions. In these areas the burden of proof is now reversed once the claimant establishes his or her case to an initial level.
