Prominent among the commissions were the Shah Nawaz Committee of 1956 headed by Shah Nawaz Khan and the Mukherjee Commission, the one-man body headed by Justice Manoj Mukherjee, a retired judge of the Supreme Court of India, instituted in 1999.
The Mukherjee commission had dismissed the air crash theory.
"One of the main reasons for Justice M.K. Mukherjee to dismiss the air crash theory was that the Japanese cremation/hospital records of 1945 vintage did not contain any reference to either Bose or any of the people claimed to have been cremated after the reported air crash," the book said.
In 1994, the Ministry of Home Affairs asked the Ministry of External Affairs for the copy of a Japanese record conclusively proving Netaji's death. The ministry responded through a Top Secret note that it had none, the book claimed.
American DNA expert Terry Melton had agreed to undertake a test of the Renkoji remains in 2001, but it could not be done as the government developed cold feet.
"Suresh Bose, one of the older brothers of Netaji and a member of the Netaji Subhas Chandra Bose Inquiry Committee, stated on oath before his death in 1972 that his brother was alive at the time," said the book, published by Vitasta Publishing Pvt. Ltd.
"The Mukherjee Commission was constrained to conclude that there was no clinching evidence to prove that Bhagwanji, a secretive holy man who died in Faizabad in 1985 with links to Suresh Bose, was not Netaji, as handwriting and DNA tests performed by government experts were negative," reads the book.
The book claims that the tests done to prove the holy man Bhagwanji (Gumnami Baba) of Faizabad was Netaji "were fudged".
In his book, Dhar has written about a systematic obstruction of justice by the government of India in its 'stranger-than-fiction' subplots, relying heavily on official records, the bulk of them still security-classified in violation of democratic norms.
"It is something that started in 1946 but the issue is still a mystery. I want to raise the issue of transparency and justice. It is a story but the main intention is to obtain declassification of official records," said Dhar.
