29 to 4: mapping every repealed Act to its new Code

The single most useful thing a practitioner can do in the first month after the Codes come into force is to map. Take every compliance obligation your organisation was already discharging, find its new Code home, and note the section number. Once you have the map, you know what is genuinely new (the parts of the Codes without a predecessor Act) and what is a re-labelling of what you were already doing.

This lesson gives you the map for all 29 repealed Acts. The mapping is at the level of statute, not clause. Each Code carries the substance of the Acts it repeals across into its own scheme, but individual sections may have been re-numbered, thresholds may have moved, and some clauses may have been dropped or added. Use this map as an index, not as a substitute for reading each Section in the Code.

Repealed by the Industrial Relations Code 2020

Three central Acts repealed by Section 104 of the IR Code:

1. The Trade Unions Act, 1926 is now Chapter III (Sections 5 to 26) of the IR Code. Registration of unions, rights and liabilities of registered unions, and dissolution now live here. The main operational change is the introduction of the "sole negotiating union" concept and the negotiating council mechanism under Section 14 [L3-C1].
2. The Industrial Employment (Standing Orders) Act, 1946 is now Chapter IV of the IR Code (Sections 28 to 39). The Model Standing Orders now issue from the Central Government. The applicability threshold has moved from 100 workers to 300 workers under Section 28 [L3-C2]. If your establishment was in the 100-299 band you have gained an exit from certification, but your existing certified standing orders continue to operate unless expressly withdrawn.
3. The Industrial Disputes Act, 1947 is spread across Chapters V (Voluntary Reference of Disputes to Arbitration), VI (Mechanism for Resolution), VII (Strikes and Lock-Outs), VIII (Lay-off, Retrenchment, Closure), IX (Special Provisions), and X (Unfair Labour Practices) of the IR Code. The most consequential change is the raising of the layoff/retrenchment prior-permission threshold from 100 workers to 300 workers under Section 77 [L3-C3].

Repealed by the Code on Wages 2019

Four central Acts repealed by Section 69 of the Wages Code:

1. The Payment of Wages Act, 1936 is now Chapter III (Sections 15 to 25) of the Wages Code. Timely payment, permissible deductions, deduction caps, and the fines regime move over. Coverage is now universal (no wage ceiling), which is the biggest structural change from the old Act.
2. The Minimum Wages Act, 1948 is now Chapter II (Sections 5 to 14) of the Wages Code. The scheme is retained but is now overlaid by a new national floor wage under Section 9 [L3-C4]: no State minimum wage may be less than the floor wage fixed by the Central Government.
3. The Payment of Bonus Act, 1965 is now Chapter IV (Sections 26 to 41) of the Wages Code. Eligibility, computation, disqualifications and rectification move over largely intact.
4. The Equal Remuneration Act, 1976 is now folded into Section 3 of the Wages Code (prohibition of gender discrimination in wages). The stand-alone Act is repealed but the gender-neutrality principle is now embedded in the wage-payment machinery of the Code.

Repealed by the Code on Social Security 2020

Nine central welfare Acts repealed by Section 164 of the SS Code:

1. The Employees' Compensation Act, 1923: now Chapter VII (Sections 74 to 99).
2. The Employees' State Insurance Act, 1948: now Chapter IV (Sections 24 to 53).
3. The Employees' Provident Funds and Miscellaneous Provisions Act, 1952: now Chapter III (Sections 15 to 23).
4. The Employment Exchanges (Compulsory Notification of Vacancies) Act, 1959: now Chapter XIII.
5. The Maternity Benefit Act, 1961: now Chapter VI (Sections 59 to 72).
6. The Payment of Gratuity Act, 1972: now Chapter V (Sections 53 to 58) [L3-C5].
7. The Cine Workers Welfare Fund Act, 1981: subsumed into Chapter IX.
8. The Building and Other Construction Workers Welfare Cess Act, 1996: now Chapter VIII (Sections 100 to 108).
9. The Unorganised Workers' Social Security Act, 2008: now Chapter IX (Sections 109 to 113); note that Chapter IX also introduces, for the first time, a separate framework for gig and platform workers in Section 114.

Repealed by the OSH Code 2020

Thirteen central Acts repealed by Section 133 of the OSH Code, including the Factories Act 1948, Mines Act 1952, Contract Labour (Regulation and Abolition) Act 1970, Inter-State Migrant Workmen Act 1979, Beedi and Cigar Workers Act 1966, Motor Transport Workers Act 1961, Plantations Labour Act 1951, Working Journalists Act 1955 and 1958 (two Acts), Sales Promotion Employees Act 1976, Cine Workers Act 1981, Dock Workers (Safety, Health and Welfare) Act 1986, and the Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act 1996. The consolidation logic is that all thirteen were doing conceptually similar work: setting the safety, health and working-condition baseline for a specific industry. The OSH Code merges them into a single framework with industry-specific chapters.

How to use this map

Take your existing compliance calendar. For every recurring filing, register, licence, or certificate you had on it as of 20 November 2025, find the row in this map that covers the old Act. That gives you the new Code Chapter to look at. Then find the corresponding Section in the new Code and the corresponding Rule. In many cases, the operational obligation carries over (a return that was annual under the old Act is annual under the Code; a register that had columns A, B, C now has columns A, B, C, D). In a few important cases the threshold or the frequency has moved, and those cases are the ones this course spends most of its time on. Modules 2 through 5 will take you through each Code in that spirit.
