All landmark court rulings favouring the Orang Asli in recent years may end up being reversed if the government pushes ahead with its proposed amendments to the Aboriginal Peoples Act (Act 134), according to a senior lawyer.

Steven Thiru, a co-chair of the Bar Council's Orang Asli Committee, said this is a real concern as parliament has the power to enact laws that would nullify whatever the earlier decisions delivered by the courts.
