The All-India Services Act, 1951 (Act No. 61 of 1951) is a foundational piece of Indian legislation that provides the statutory framework for the management of the All-India Services (AIS). It was enacted by Parliament on October 29, 1951, to regulate the recruitment and conditions of service for persons appointed to the AIS, which are common to both the Union and the States.
The Act's origin lies in the need to establish a unified administrative system after India's independence, replacing the colonial-era services like the Indian Civil Service (ICS). While the Constitution continued the existing rules under Article 313, the Act was necessary to provide the requisite statutory authority for the Central Government to manage the services and promulgate decisions on service conditions. This structure solved the problem of maintaining administrative uniformity and efficiency across the new federal polity, reinforcing the concept of cooperative federalism.
The core mechanism of the Act is contained in Section 3, which empowers the Central Government to make rules for the regulation of recruitment and conditions of service, but only after consultation with the Governments of the States concerned. The Act governs the three existing All-India Services: the Indian Administrative Service (IAS), the Indian Police Service (IPS), and the Indian Forest Service (IFS), which was created under the Act in 1966. The Act is directly connected to Article 312 of the Constitution, which enables Parliament to create All-India Services.
The Act has been subject to amendments, including one in 2020 that omitted the phrase "including the State of Jammu and Kashmir". More recently, the Union government proposed amendments to the cadre rules, which are framed under this Act, to ensure a mandatory "Cooling Off" requirement of 3 years after central deputation and to compel state governments to offer officers for central deputation. A proposed amendment in 2022 also sought to introduce a periodic performance review for officers after five years of tenure.
