Returning the Office of Profit bill was the most difficult decision President APJ Abdul Kalam made during his tenure in the country's highest office.
"The difficult decision is, of course, one bill -- the Office of Profit -- that bill I had to return to Parliament. As per the Constitution, a President can do it but I happened to be the first fellow," the 75-year-old Kalam said in an interaction with PTI journalists in New Delhi.
He was replying to a question as to what was the most difficult moment during his term as President.
"And also a debate was started in the nation and Parliament took a decision to establish some guidelines," Kalam, whose term as President expires on July 24, said.
The President, in May last year, had returned the Office of Profit bill that exempted 56 posts from the purview of the bill, asking Parliament to reconsider it and to have "comprehensive and generic" criteria besides making it "fair and reasonable" and applicable in a "clear and transparent" manner across all the states and union territories.
While returning the bill, Kalam had urged both houses of Parliament to reconsider the propriety of the applicability of the law with retrospective effect.
The second most difficult moment, the President said, was how to introduce bio-fuel in the country. "Now the government has agreed for 10 per cent mixing of bio-fuel in petrol and diesel," he said.
Kalam hoped car manufacturers will modify engines so that a higher percentage of bio-diesel extracted from jathropa plants and sugarcane can be mixed in fuels to reduce the nation's dependence on imports of petroleum products.
