"On August 31, 1974, sitting MP MB Rana passed away and then speaker GS Dhillon decided not to adjourn the House and Budget was presented," a source told CNN News 18.
Budget's postponement over Ahamed's death is unlikely
There has been a precedent where a Budget presentation has been made following an obit reference about a deceased MP.
Ahamed was an MP in the Lok Sabha (LS). The LS can be adjourned to mourn his death, while the Budget presentation can be made in the Rajya Sabha.
Sources said all Budget papers printed bear today's date and its postponement will create problems.
