The All India Services plays the most prominent role in civil service. The candidates to these services are recruited on all India basis and can be posted both at the centre or at the state.
Presently India has three All India services.
1. Indian Administrative Services (IAS)
2. Indian Police Services (IPS)
3. Indian Forest Services (IFS)
These services are called as All India services as they belong both to the Central and State Governments. The services of these officers could be utilized by both the central and state governments and they can be transferred from central to state and vice-versa.
Article 312 (i) of the Indian Constitution states that, Rajya Sabhajnitiates a resolution supported by not less than 2/3rd of the members present and voting. If necessary, in the national interest, Parliament may by law provide for the creation of one or more All India Services.
