The Constitution of Nepal guarantees a wide range of fundamental rights, including the right to equality, the right to freedom, the right against untouchability and discrimination, the right to information, and the right to a clean environment.
These rights are enforceable: a citizen whose fundamental right has been violated can petition the Supreme Court or a High Court directly for a remedy. That is the key distinction from the Directive Principles of State Policy, which set out the state's long-term goals but are not directly enforceable in the same way.
Candidates are regularly asked to distinguish between fundamental rights, directive principles and fundamental duties. If you can state which of the three is enforceable in court and which is not, you can answer most of what is asked about them.
