Ensuring absolute transparency, administrative rigor, and adherence to standard democratic operating protocols, the Election Commission of India (ECI), under the supervision of the Chief Electoral Officer (CEO) of Tamil Nadu, concluded the first computerized randomisation of Electronic Voting Machines (EVMs) and Voter Verifiable Paper Audit Trail (VVPAT) units for the upcoming Assembly by-elections in the Madurantakam (Chengalpattu district) and Dharapuram (Tiruppur district) constituencies.
The procedural milestone was conducted in the presence of district election officers, returning officers, and designated authorized representatives from all recognized national and state political parties, verifying the impartiality of machine allocations across designated polling stations.

2. The Two-Stage EVM Randomisation Process Explained
To prevent any pre-programming or localized manipulation of voting hardware, the Election Commission employs an ironclad two-stage computerized randomisation process:
- First Randomisation (Constituency Level): From the district master warehouse pool of EVMs, computerized software randomly selects the exact serial-numbered Control Units, Ballot Units, and VVPATs assigned to each Assembly Constituency. Lists of the selected serial numbers are printed and handed over to representatives of all political parties.
- Second Randomisation (Polling Booth Level): Following the finalization of the contesting candidate list and symbol allotment, a second randomisation determines which specific machine will be placed at which exact polling booth in the constituency.
- Mock Poll Testing: Before actual voting commences on polling day, a mandatory mock poll of at least 50 votes is conducted in front of polling agents of all parties, and VVPAT paper slips are manually counted and verified against the electronic CU tally.
3. Deployment of Central Armed Police Forces (CAPF) and Webcasting
District election officials outlined extensive security and logistical arrangements to ensure free and fair polling:
Key Security and Monitoring Measures:
1. 100% Live Webcasting: All polling stations will feature continuous high-definition live streaming to the District Collectorate and CEO Command Center in Chennai.
2. Micro-Observers: Central government employees deployed as neutral micro-observers at all vulnerable and critical polling stations.
3. CAPF Strongroom Security: Inner-cordon 24/7 security of EVM strongrooms managed by Central Armed Police Forces (CAPF), with state armed police securing outer perimeters.
4. Voter Awareness and Model Code of Conduct Enforcement
Flying Squad Teams (FST) and Static Surveillance Teams (SST) have been deployed 24/7 across border check-posts in Chengalpattu and Tiruppur districts to enforce the Model Code of Conduct (MCC), preventing the illicit flow of cash, liquor, or freebies designed to influence voters:
- cVIGIL Mobile App: Citizens can capture real-time photo and video evidence of MCC violations, which automatically alerts the nearest flying squad for on-site investigation within 100 minutes.
- Voter Information Slips: Distribution of personalized QR-coded voter information slips to every household to ensure smooth, queue-free voting on polling day.
