"It is not the people's verdict because the CPI-M managed to manipulate the EVMs during the elections with the help of the administration," Tripura Pradesh Congress President (TPCC), Sudip Roy Burman told reporters.
The Left Front secured 50 seats in the 60-member assembly to return to power for the fifth time in a row while the Congress managed to get only 10 seats.
Two days after the TPCC reviewed the election results on Tuesday, Burman claimed the EVMs used in the state were earlier used in Assam in 2011 and those machines might have been tampered with at that time.
"How those machines can be used during the Tripura election when a case was pending in the Supreme Court?" he asked.
He said the party was consulting the matter with qualified engineers and contemplating moving court.
