FR–DPSP conflict & Fundamental Duties

UPSC tests the conceptual distinction between FR (enforceable) and DPSP (non-enforceable) through conflict scenarios, specific article recall, and the 42nd Amendment watershed moment. Questions often ask which article belongs to which category, impact of DPSP on FR, and Fundamental Duties added in 1976. Avoid conflating DPSP with FR; remember DPSP are directive principles, not justiciable.
