The Supreme Court collegium's recommendation for out-of-turn elevation of two judges is "appalling" and "outrageous" and has sent "shockwaves through the legal community", a former judge of the Delhi High Court written to President Ram Nath Kovind. If the recommendation for the elevation -- which in one case will supercede more than 30 senior judges -- is accepted, the "historical blunder" will ruin the credibility of the country's top court, his letter said.
