Distinguish primary from secondary sources with examples from Nepali legal materials.

The law itself — the doctrinal researcher's raw material:1. Constitutions — the Constitution of Nepal 2015 (the authentic Nepali text controls; the official translations aid).2. Statutes — Acts, Ordinances, the 2074 Code family; the Gazette (the amendments' home); delegated legislation (rules, regulations, by-laws).3. Precedents — the Supreme Court's decisions (NKP — Nepal Kanoon Patrika; the official Nepal Law Reports; the Supreme Court's database), High Court and lower decisions (persuasive), foreign precedents (comparative use).4. Treaties — the treaty texts and Nepal's ratification record (the Treaty Act 2047's world).5. Bills and drafting materials — where available (the interpretive aids of Interpretation of Law, LAW5504 U2).6. European-and-international tribunals' materials — for the comparative papers.
