The mystery of the “Madu” machine—the black box attached to EVMs that sparked a political firestorm this week—has finally been addressed. But the answer has arguably deepened the procedural fog surrounding the Mumbai Civic Elections.
The Official Line: “It is Just a Backup”
In a pre-election press conference, BMC Commissioner Bhushan Gagrani clarified that the device in question is technically called the “Printing Auxiliary Display Unit” (PADU).
“We are showing the PADU machine, which will serve as a backup option for voting. A total of 140 PADU units have been sent… This is the first time PADU machines will be used in the elections.”
— Bhushan Gagrani, BMC Commissioner
What is a PADU? (The Technical Reality)
While the Commission calls it a “backup,” technical specifications reveal it is far more than a simple screen. Developed by Bharat Electronics Limited (BEL), the PADU is a “Slave Unit” that connects directly to the EVM’s Control Unit.
Crucially, it is not just a display; it is a data extractor. According to technical manuals, this unit is capable of printing:
- Candidate-wise vote tallies.
- Event Logs: Exact timestamps of when the poll started and ended.
- Voter Timestamp Data: The time every single vote was cast.
This capability is exactly why the secrecy surrounding its introduction is so volatile. A machine that can extract and print minute-by-minute voter data is a powerful audit tool. If mishandled or manipulated, it could theoretically be used to map voting patterns with terrifying precision.
The Procedural Ambush
The core issue is not the technology, but the timing. Raj Thackeray’s primary allegation—that political parties were never shown this machine during the standard First Level Checking (FLC)—stands unrefuted.
The Verdict
The “Madu” is indeed a “PADU.” But by hiding a legitimate backup tool in the shadows, the Election Commission has turned a technical solution into a political weapon.
