Legal framework for IAS postings:

Under the All India Services (Conduct) Rules 1968 and Indian Administrative Service (Cadre) Rules 1954, posting and transfer decisions are the prerogative of the state government (for state cadre postings) or DoPT (for central deputation).

Civil Services Board (CSB):

Post the T.S.R. Subramanian SC judgment (2013), states were required to constitute a Civil Services Board headed by the Chief Secretary to recommend transfers and postings. However:

• The CSB recommendation is advisory, not binding on the state government
• The Chief Minister/Council of Ministers retains final authority
• In practice, political considerations influence many postings despite the CSB mechanism

How officers informally influence postings:

• Submitting a formal request letter to the Chief Secretary with a justification (health, expertise, family)
• Spouse-posting requests (DoPT OM Nov 24 2022 — see related question) carry significant institutional weight
• Performance and domain expertise — officers with specialized skills (finance, technology, tribal welfare) are often consulted before posting to relevant roles

What officers cannot do:

• There is no legal right to refuse a posting (refusal can constitute misconduct under Conduct Rules)
• Approaching the media or politicians directly to influence a posting is prohibited
• Filing a court case to resist a posting (except in cases of clear mala fide or minimum tenure violation)
