I have done some research on this topic during the past weeks. There has been many changes outside Mauritius to bring forward a more representative judiciary. But on our island, it does not seem to be a problem at all! But God knows how we are racist?
Judges act in a way for the 'show' of public representation as here, we have a great diversity of culture and religion. If a judge seems to favor someone or to sentence someone according to his/her caste/religious belief/color/age/gender/sexual orientation then this judge is bound to be eradicated from the judicial system.
We do not have a formal debate for this in Mauritius. And I can't find cases of discrimination. In the past, however, I think there was judicial bias against women. But now we have more female judges in Mauritius.
