Addressing Mathadi workers (head loaders) in Navi Mumbai on Sunday, Pawar had asked them to take advantage of the multi-phase polling in the state by voting twice, first at their hometowns and then at places of work. He also asked them to "erase the indelible ink applied to the forefinger".
NCP spokesman Nawab Malik told reporters that EC had sent a notice to Pawar based on complaints of a few opposition parties regarding the comments.
"The clarification has been sent and we are confident that appropriate decision will be taken," he said.
After his statement kicked up a controversy, Pawar sought to tone it down, saying his remarks were made in a "lighter vein and had a tinge of satire".
