Justice Markandey Katju was an eminent judge of the Supreme Court of India and formerly, Chairman of the Press Council of India. A man with extensive juridical skill and knowledge which accompanies said experience. And when such a person writes and is active in the blogosphere, people take note. Keeping this in mind, he may wish to screen what he publishes under his name, online or otherwise. Particularly, calling M.K. Gandhi a British agent who harmed India, is not something that will endear him to a lot of people.

But we refuse to judge a judge for making such judgy comments on the Mahatma.

Gandhi was a great man, with profound ideals and a strong resolve. A leader of the masses, who gave direction and a purpose to our freedom struggle and was instrumental in our achievement of independence.

However, he was a man. And men have their faults.

Justice Katju writes about how Gandhi and his devotion to Hinduism indirectly propagated the divide-and-rule policy of the British. Katju also propounds that Gandhi led the freedom movement away from a revolutionary struggle to "a harmless nonsensical channel called Satyagrah."

Gandhi's famous trusteeship theory, which says that all the resources and wealth of society are placed under a trust of the people and the wealthy landlords, money lenders etc are trustees of this trust, is according to Katju, "all nonsense, and an act of deceiving the people."
