In this open letter, Amnesty International urges the Minister to ensure that the public hearing on plans by the company, Vedanta Aluminium, for the six-fold expansion of its alumina refinery at Lanjigarh is postponed until existing concerns are addressed. Amnesty International is gravely concerned by the evidence that – far from addressing the negative human rights impact of the existing refinery – the government of Orissa and Vedanta Aluminium appear to be continuing with practices that breach international and national laws and standards.
