Introduction to Legal Research and Writing

Legal research and writing are foundational skills for any law student and practicing attorney. In Missouri, as in other jurisdictions, these skills are essential for effective practice.

Legal Research

Legal research involves the process of identifying and retrieving information necessary to support legal decision-making. Key resources for legal research include primary sources (statutes, cases, constitutions, regulations) and secondary sources (law reviews, treatises, legal encyclopedias).

Legal Writing

Legal writing is a specialized type of technical writing used by lawyers to express legal analysis and legal rights and duties. It includes legal memoranda, briefs, and judicial opinions, among other documents.

Primary Sources


Missouri Revised Statutes (RSMo): These are the codified laws of the State of Missouri. Students must become familiar with navigating the RSMo to find relevant statutory law for various legal issues.

Case Law

Missouri case law is developed through the decisions of Missouri courts. Key reporters include the Southwestern Reporter for appellate decisions and Missouri Reports for Supreme Court decisions.


Missouri Code of State Regulations (CSR): This contains rules created by state agencies.


U.S. Constitution and Missouri Constitution are both foundational documents that law students must understand.

Secondary Sources

Case Law Review Using IRAC

Palsgraf v. Long Island Railroad Co. (1928)

  • Issue: Whether the railroad was negligent and if that negligence extended to unforeseen plaintiffs.
  • Rule: The court established the principle that the defendant owes a duty of care only to those who are reasonably foreseeable victims of their actions.
  • Application: The court found that Palsgraf’s injuries were not the foreseeable result of the railroad’s employees’ actions.
  • Conclusion: The court ruled in favor of Long Island Railroad, holding that the injury to Palsgraf was not a foreseeable harm arising from the negligence of the railroad employees.

Missouri v. Jenkins (1989)

  • Issue: The issue was whether the district court could order the state of Missouri to increase taxes to fund remedial education programs following a finding of de jure segregation.
  • Rule: The U.S. Supreme Court held that federal courts do not have the authority to directly impose tax levies for school desegregation.
  • Application: The Supreme Court determined that the district court’s order for the state of Missouri to levy taxes was inappropriate because it overstepped the scope of federal judicial authority.
  • Conclusion: The decision was reversed and remanded, limiting the power of federal courts in ordering remedies that directly affect a state’s fiscal policies.
