1. Common law: the English family — precedent's primacy (the stare decisis), the judge-made law's growth from case-to-case (the "brooding omnipotence" myth's correction: the living accumulation), the adversary procedure, the jury's history, the law-equity division's legacy; the diffusion: USA, India (Nepal's procedural parent), Canada, Australia, the commonwealth family; the method: induction-and-distinguishing; the minds: Blackstone-to-Holmes ("the life of the law has not been logic: it has been experience" — the classic quotation to attribute);
2. Civil law (the Romanistic family): the Roman-jus commune descendants — the codification's primacy (the Code Napoléon 1804 as the model), the statute as the law's source, the judge as the code's mouth (Montesquieu's bouche de la loi), the inquisitorial tradition's history, the scholarly doctrine's weight (the professor's-and-commentator's role — la doctrine), the deductive method; the diffusion: France, Germany (the Pandectists' science and the BGB 1900 — the second great branch), the Latin world, East Asia's adaptations (Japan, China's private-law borrowings), and Nepal's own codified style's affinity (the Muluki Ain tradition — the system's formal kinship despite the procedure's common-law inheritance);
3. Socialist legal system: the Soviet-and-socialist family — the law as the state's-and-party's instrument (the superstructure theory: the economic base determining the law), the public law's primacy (the plan-and-property's state design), the tribunals' history (the comrades' courts), the legal profession's state-service character, the critique-and-collapse (the post-1989 transitions: the systems' re-convergence toward the civil-law mainstream; the continuing Chinese-and-Vietnamese variations — the "socialist market" hybrids); the family's lessons (the law's instrumentality's dangers — the rule-of-law's counter-lesson).
