Ravi was a founding member of the Anti-Death Penalty Asia Network and the Singapore Anti-Death Penalty Campaign’s community group. Over the course of his career, he worked to save more than 40 inmates from death row. The legal challenges brought by Ravi to court between 2010 and 2012 in the case of Yong Vui Kong, a young Malaysian national on death row in Malaysia, led to an indirect moratorium on death penalty cases in the country, which ultimately contributed to the amendment of the law in respect of the mandatory death penalty for certain drug offences. His involvement in the case of Nagaenthran K Dharmalingam, an intellectually-disabled death row inmate, drew worldwide attention. In addition to his efforts in Malaysia and Singapore, Ravi worked as a mentor to lawyers in Pakistan and Tanzania on challenging the death penalty in these countries as part of a scheme organised by the
6th World Congress Against the Death Penalty and the non-governmental organisation,
Together Against the Death Penalty (ECPM).
