Legal professionals must skillfully evaluate source credibility to build strong arguments. This involves assessing factors like author expertise, publication reputation, and currency of information. Proper evaluation ensures reliance on authoritative and relevant sources.

Critical analysis of primary and secondary legal materials is crucial. Understanding court hierarchies, precedential value, and subsequent treatment of cases helps determine their weight. For scholarly articles and practitioner materials, examining methodology and practical applicability is key.

Types of legal sources

• Legal sources form the foundation of legal research and writing, providing the basis for legal arguments and decisions
• Understanding different types of legal sources is crucial for effective legal analysis and interpretation in the field of Legal Method and Writing
• Proper categorization of legal sources helps in determining their weight and applicability in legal reasoning

Primary vs secondary sources

• Primary sources contain the law itself, created by government bodies with the authority to make law
• Primary sources include constitutions, statutes, regulations, and court decisions
• Secondary sources explain, analyze, or comment on primary sources
• Secondary sources encompass legal treatises, law review articles, and legal encyclopedias
• Primary sources carry more weight in legal arguments than secondary sources

Binding vs persuasive authority

• Binding authority must be followed by courts in a particular jurisdiction
• Binding authority includes constitutions, statutes, and higher court decisions within the same jurisdiction
• Persuasive authority can influence a court's decision but is not mandatory to follow
• Persuasive authority includes decisions from other jurisdictions, secondary sources, and dissenting opinions
• The weight of persuasive authority depends on factors such as the reputation of the source and the strength of its reasoning

Hierarchy of legal authority

• Constitutional law sits at the top of the legal hierarchy, superseding all other forms of law
• Federal laws take precedence over state laws in areas where the federal government has jurisdiction
• Statutes enacted by legislatures generally override common law (judge-made law)
• Within court decisions, higher court rulings bind lower courts in the same jurisdiction
• Executive orders and administrative regulations must comply with statutory and constitutional law

Factors affecting credibility

• Credibility assessment is a critical skill in Legal Method and Writing for evaluating the reliability and persuasiveness of legal sources
• Understanding these factors helps legal professionals determine the weight to give different sources in their research and arguments
• Credibility factors apply across various types of legal sources, from case law to scholarly articles

Source reputation

• Older sources may be valuable for historical context or tracing the development of legal principles
• Publication dates are crucial for assessing the currency of statutes, as laws can be amended or repealed
• In rapidly evolving areas of law (technology, healthcare), more recent sources carry greater weight
• Regular updates or new editions of legal texts indicate ongoing relevance and accuracy

Peer review process

• Peer-reviewed legal journals subject articles to scrutiny by experts in the field before publication
• The peer review process helps identify errors, inconsistencies, or weak arguments in legal scholarship
• Law reviews from top-tier law schools often employ rigorous peer review processes
• Peer-reviewed sources generally carry more weight than non-reviewed publications in academic circles
• Information about the peer review process is typically available in the journal's editorial policies

Citation frequency

• Frequently cited sources often indicate widespread acceptance and influence in the legal community
• Citation analysis tools (Westlaw KeyCite, LexisNexis Shepard's) track how often a source is referenced
• High citation frequency can suggest that a source is considered authoritative on a particular legal issue
• Recent citations are generally more valuable than older ones in assessing current relevance
• Citation patterns can reveal the evolution of legal thought on a specific topic over time

Evaluating online sources

• Online legal research has become increasingly prevalent in Legal Method and Writing, necessitating skills in evaluating digital sources
• The internet provides quick access to a vast array of legal information, but not all online sources are equally reliable
• Critical evaluation of online sources helps ensure the accuracy and authority of information used in legal analysis

Official vs unofficial websites

• Official government websites (.gov domains) provide authoritative versions of statutes, regulations, and court opinions

• Understanding court hierarchy helps determine the authoritative weight of a case decision

Precedential value

• Published opinions typically carry more precedential weight than unpublished ones
• En banc decisions (full court) generally have greater precedential value than panel decisions
• Majority opinions set precedent, while concurring and dissenting opinions may offer persuasive reasoning
• The breadth or narrowness of a court's holding affects its applicability to future cases
• Precedential value can be influenced by the clarity and thoroughness of the court's reasoning

Age of decision

• Recent decisions are generally more relevant, especially in rapidly evolving areas of law
• Older cases may still be authoritative if they have not been overruled or superseded
• The age of a decision should be considered in light of subsequent legal developments
• Historical cases can provide important context for understanding the evolution of legal principles
• Be cautious of relying on older decisions without checking their current status

Subsequent treatment

• Shepardize or KeyCite cases to determine how they have been treated by subsequent court decisions
• Cases that have been overruled or abrogated lose their precedential value
