Explain the socialist legal system with its rise and decline.

A legal system is the integrated whole of a society's law: its sources (constitution, statutes, precedent, custom), institutions (courts, tribunals, the legal profession, enforcement machinery), concepts-and-categories (its doctrinal architecture — property, obligation, crime in its own design), legal method (how lawyers argue-and-judges decide), and legal culture (the society's legal values-and-attitudes). The comparative lawyers' frame (Comparative Law's canon — Semester 3): the legal family (the world's systems grouped by kinship: René David's families, Zweigert-and-Kötz's styles, Glenn's traditions); the classification's criteria (history, sources' hierarchy, methodology, ideology).
