A legal case study includes the detailed study, analysis and research upon a particular legal issue. This is considered one of the most efficient methods for acquiring legal knowledge as it concentrates only on a particular issue. This method is used by the research students, professors and lawyers. Even though it helps to acquire in-depth knowledge about the evolution of the law, supplementing legislation, circumstances for the enforcement, social scenario, application or impact upon the society, drawbacks of the law or case law, friction with the society and culture include the advantages in legal case study, the time consuming aspect is a major demerit. Also it deals only with rights and duties of an individual, group or community. Mostly suitable for the students of research in law.
