Major opposition parties have decided to approach the Supreme Court for the demand of verification of at least 50% of VVPAT machines with EVMs.
Relevance of Topic for Prelims 2019:
Due to the frequent issues and objections involved with EVMs & VVPAT, candidates are expected to know about facts related to VVPAT.
- Voter Verifiable Paper Audit Trial (VVPAT) is an independent system attached to an EVM that allows the voters to verify that their votes are cast as intended.
- Voters can see the printout but not take it out; VVPAT helps him in verifying that his vote was registered correctly.
- Rule 49A of the Conduct of Elections Rules, 1961, provides that every EVM shall have a control unit and a balloting unit. Under this provision, the Election Commission of India has provided for the VVPATs in the election process.
How it Works?
- When a vote is cast, a slip is printed on the VVPAT printer containing the serial number, name and symbol of the candidate voted.
- This remains visible to the voter through a transparent window for 7 seconds.
- Thereafter, this printed slip automatically gets cut and falls into a sealed drop box.
- VVPAT’s use thermal printers and print lasts for around 5years.
- These slips can be used for tallying by the ECI in later stage of time if needed.
Who makes VVPAT?
- VVPATs are made by only two public sector units namely- Bharat Electronics Limited (BEL) and Electronics Corporation of India Limited (ECIL) in consultation with experts from Election Commission of India.
When was VVPAT first used?
- VVPATs were first used in the by-election for the ‘Noksen Assembly’ seat in Nagaland in 2013.
- In the 2019 Lok Sabha elections, VVPATs are being used in all the constituencies and all the EVMs.
Why is the ECI opposed to 50% verification of VVPATs?
- As per ECI, this whole process will lead to delay in the result declaration by minimum 6 days.
- ECI has opined that this will unnecessarily create infrastructural burden and wastage of manpower & resources of the organisation and country as a whole.
