KG Kannabiran, 1929-2010.
Among much else: "In 1971, he filed a writ petition successfully challenging the Andhra Pradesh Preventive Detention Act, 1970, under which writers, poets and intellectuals had been arrested." (The Hindu, December 31 2010).
Especially at a time Binayak Sen has been imprisoned, you will be missed, Mr Kannabiran.
Go in peace.
