What is Current Upward Limit of Election Expenses in India?

During 2009 Lok Sabha elections, most candidates were allowed to spend a measly Rs 25 lakh on the campaign, while the cap for assembly seats was Rs 10 lakh. The EC revised the upward limit to Rs 40 lakh and Rs 16 lakh for Lok Sabha and assembly constituencies, respectively. Such numbers may suffice for student union elections at a sizeable university, but do no justice to the crores that candidates routinely spend in order to win state-level or national elections.
