 Singh was sworn in on 28 July 1979 but never faced Parliament to prove his majority when Reddy convened it on 20 August.Reddy had appointed him Prime Minister since he had produced a letter claiming to have a parliamentary majority with the support of the opposition Congress Party led by his rival, the former Prime Minister Indira Gandhi.In return for her support, Gandhi demanded that a law establishing special courts to try her and her son Sanjay Gandhi be repealed – a proposition that was unacceptable to Charan Singh.
