This discussion questions the legal standing of an executive order that introduced the New Pension Scheme (NPS) before it was enacted into law, potentially overriding Article 309 pension rules. While Supreme Court rulings suggest executive orders cannot supersede Article 309, the government later passed the PFRDA Act with retrospective effect from the executive order's date. The response suggests this retrospective enactment removes ambiguity, making a legal challenge based on the executive order's initial validity unlikely to succeed.
