West Bengal has once again found itself in the eye of an economic storm after the Mamata Banerjee-led Trinamool Congress (TMC) government revoked three decades of industrial incentive schemes with retrospective effect. The move has sent shockwaves across the corporate fraternity, with leading business houses terming it “a betrayal of trust” and rushing to the Calcutta High Court to challenge the law’s constitutionality.
The Revocation of West Bengal Incentive Schemes and Obligations in the Nature of Grants and Incentives Bill, 2025, notified on April 2, strips away benefits provided under various industrial policies since 1993. What makes the decision unprecedented is its retroactive sweep, negating entitlements that had already accrued to investors under successive state-promised schemes.
Losses and Court Challenges
Two of the country’s most established conglomerates, the Dalmia and Birla Groups, have publicly estimated losses amounting to ₹430 crore from the rollback. Others are expected to declare figures as assessments continue.
Companies that had structured projects, expansions, and financial planning on the basis of guaranteed state support now face sudden disruption. Industry associations argue that this undermines the doctrine of “legitimate expectation” and erodes the sanctity of state commitments, principles long upheld in Indian constitutional jurisprudence.
Multiple petitions filed in the Calcutta High Court contend that the move violates Articles 14 and 19(1)(g) of the Constitution, as it imposes arbitrary restrictions on business and negates previously binding obligations.
A History of Flight and Distrust
For Bengal, the episode reopens deep wounds. Once India’s second-most industrialised state, West Bengal saw decades of decline under Communist rule marked by militant trade unionism, strikes, and an openly hostile stance toward capital. That legacy drove stalwarts like the Birlas and Singhanias away from Kolkata.
When Mamata Banerjee came to power in 2011, hopes of revival were pinned on a pro-industry policy. Yet her own political rise had been cemented by the Singur agitation, which forced Tata Motors to abandon its Nano project. The scars of that controversy linger, and today’s rollback only strengthens perceptions that Bengal remains unpredictable for business.
According to the Ministry of Corporate Affairs, more than 6,600 companies, including over 100 listed firms, shifted their base out of Bengal between 2011 and 2025. The state’s share in India’s GDP has halved since 1960, and its per capita income lags even behind neighbours like Odisha.
Welfare vs. Growth?
The government has defended the Act on grounds of “redirecting funds towards marginalised groups.” Yet economists warn that redistribution without fresh wealth creation risks collective stagnation. Incentives, they argue, are not charity but multipliers, mechanisms that attract capital, generate jobs, and expand the state’s tax base.
Critics also point out that the state’s definition of “marginalised” has often been applied selectively, with political overtones. By diverting resources away from industry towards narrowly targeted welfare schemes, the government risks prioritising short-term appeasement over long-term economic health. The result is a policy that may win political support today but could weaken Bengal’s growth foundations tomorrow.
The timing also raises eyebrows. At a moment when India, under the central government’s Production-Linked Incentive (PLI) scheme, is attracting record investments, Bengal has chosen to signal hostility to capital. In the last fiscal year, the state received a meagre ₹2,534 crore in FDI, failing to feature in the top ten destinations.
The Road Ahead
The legal battle in the Calcutta High Court will determine whether the retrospective rollback survives judicial scrutiny. But the immediate casualty is confidence. Investors, already cautious due to Bengal’s law-and-order concerns, now face the additional risk of seeing written commitments invalidated after decades.
For ordinary Bengalis, the consequences could be severe. Job creation in the private sector, already sluggish, may suffer further setbacks. A state struggling with high multidimensional poverty and a fiscal deficit of 38% of GSDP can ill afford another round of industrial flight.
A Bitter Irony
At the Bengal Global Business Summit earlier this year, the Chief Minister welcomed business leaders with promises of opportunity and cooperation. Barely months later, the very foundations of those assurances have been shaken.
The irony is stark: at a time when the rest of India is racing ahead with pro-growth policies, West Bengal seems determined to revisit the failed economics of the past. The ones who will ultimately pay the price are not the conglomerates with diversified portfolios, but the ordinary workers of Bengal, caught in the crossfire between politics and prosperity.
