I was selected for a job at IDBI Bank through the IBPS exam. The recruitment process stated that selected candidates would be employed in a public sector bank. However, now the government is planning to privatize IDBI Bank. Can I file a case against this, and if so, who should I file it against?

Based on current Indian law, you cannot file a case against the privatization of IDBI Bank. The government has the right to privatize public sector banks, and your employment contract likely includes a clause regarding potential privatization. You can approach the bank to discuss potential implications of privatization on your employment, but legal action is unlikely to be successful.
