Prelims level: Old Pension Scheme , NPS
Mains level: Read the attached story
Introduction
- The Maharashtra Cabinet has approved a proposal allowing certain state government employees to opt for the old pension scheme (OPS).
- The option is extended to employees who joined the service after November 1, 2005, based on recruitment advertisements issued before that date.
Transition in Pension Schemes
- Old Pension Scheme (OPS): The OPS guaranteed a pension of half the last basic salary plus dearness allowance after a minimum of 10 years of service, without employee contributions. It also provided family pension and Death cum Retirement Gratuity (DCRG).
- New Pension Scheme (NPS): Introduced to address the growing pension bill, the NPS is a market-linked, participatory scheme requiring contributions from both employees and employers.
Background and Implementation of NPS
- OASIS Project: Initiated in 1999, it led to the recommendation of the NPS by the Atal Bihari Vajpayee government in 2003.
- Scheme Details: Employees contribute 10% of their basic salary, matched up to 14% by the employer. The funds are invested in PFRDA-regulated pension funds with market-linked returns.
- Account Management: NPS provides a Permanent Retirement Account Number (PRAN) for lifelong account management.
- State Adoption: All states except West Bengal have implemented the NPS. Some opposition-ruled states announced plans to revert to the OPS.
Rationale Behind NPS Adoption
- Pension Debt Sustainability: The OPS was a fiscal burden without accumulated funds, whereas the NPS relies on accumulated funds.
- Addressing Ageing Population: With increasing life expectancy, the OPS became unsustainable.
- Preventing Early Retirements: The NPS encourages longer service due to its long-term investment fund ideology.
- Investment and Flexibility: NPS offers flexible investment options and the freedom to switch investment options and fund managers.
Criticism of NPS
- Market Risks: The exposure of retirement funds to market uncertainties raises concerns about old age security.
- Pension Amount Concerns: There is no minimum pension guarantee, and pensions under NPS do not adjust for inflation.
- Accountability Issues: Questions remain about the security of the invested corpus and accountability in market failures.
Conclusion
- State Governments’ Challenge: Reverting to OPS requires careful consideration of financial implications on future generations.
- Review and Strengthening of NPS: Measures such as introducing inflation-indexed annuities, assuring minimum returns, and ensuring timely registration and contributions can strengthen the NPS.
- Balanced Approach: A nuanced approach is needed to balance fiscal sustainability with providing adequate social security to retirees.

From UPSC perspective, the following things are important :
Prelims level: VVPAT
Mains level: Free and Fair Elections
Introduction
- Recent Developments: A political alliance, has requested a meeting with the Election Commission of India (ECI) to discuss and suggest changes regarding the use of Voter Verifiable Paper Audit Trail (VVPAT) machines.
- Proposal: The alliance proposes that VVPAT slips be handed to voters to place in a separate ballot box, with 100% counting of these slips, to enhance trust in the electoral process.
What are VVPATs?
- Function and Purpose: VVPAT machines, attached to EVMs, print a slip showing the voter’s choice, allowing voters to verify their vote for seven seconds before the slip drops into a secured box.
- Development History: The concept emerged in 2010, leading to the creation of prototypes by Bharat Electronics Limited (BEL) and Electronics Corporation of India (ECIL). After trials and feedback, the design was approved in February 2013.
- Implementation: The Conduct of Elections Rules, 1961, were amended to incorporate VVPATs. They were first used in Nagaland’s Noksen Assembly constituency in 2013 and were implemented in all polling stations by the 2019 Lok Sabha elections.
Current VVPAT Slip Counting Protocol
- EC’s Decision Process: In 2018, the ECI consulted the Indian Statistical Institute (ISI) to determine a statistically robust sample size for VVPAT slip verification.
- Existing Protocol: Initially, VVPAT slips of one randomly selected polling station per Assembly constituency were counted. This was increased to five polling stations per Assembly seat after a Supreme Court judgment in 2019.
- ISI Recommendation: The ISI suggested counting VVPAT slips from 479 EVMs to ensure a high confidence level that the proportion of defective EVMs is less than 2%.
Election Commission’s Stance
- Current Verification Adequacy: The EC argues that the current practice of verifying VVPATs from five polling stations per Assembly seat exceeds the ISI’s recommendation.
- Reliability Record: The EC highlights that in past elections, no cases of vote misattribution were detected in VVPAT checks, attributing discrepancies to human errors.
- Concerns over Full Verification: The EC views 100% VVPAT verification as regressive, time-consuming, and prone to human error, akin to manual ballot voting.
Conclusion
- Debate on Electoral Integrity: The discussion around VVPAT verification reflects ongoing concerns about ensuring electoral integrity and public trust in the voting process.
- Challenges Ahead: Balancing the need for efficient electoral processes with the imperative of maintaining voter confidence remains a critical challenge for the ECI and political parties in India.
