Writers identified with the Critical Legal Studies movement (CLS) claim that there is no coherent and determinate body of legal doctrine or a distinctive form of legal reasoning, and consider that the categories available for classifying legal problems simply mask the incoherency and indeterminacy of legal doctrine, inhibit the growth of the law, and create injustice by causing us to treat unequal situations as if they were equal. Professor Barkan argues that by critiquing the jurisprudential assumptions upon which legal resources are created, materials are
collected, and research practices are justified, CLS causes us to look critically at legal research.
