Major Sources of U.S. Law and Federal-State Conflicts
This paper examines the principal sources of law under the American system of jurisprudence, including the U.S. Constitution, natural law, administrative law, statutory law, and common law. It explains how these sources generally complement one another while also identifying circumstances in which they conflict. Special attention is given to the Supremacy Clause and the legal concept of "characterization" used to resolve jurisdictional disputes. A hypothetical vignette involving a disabled African American Vietnam veteran arrested in Idaho for possessing medical cannabis legally purchased in Montana illustrates the real-world consequences of unresolved federal-state conflicts, particularly in marijuana law. The paper concludes with a call for nationwide legal harmonization.

What makes this paper effective
- The paper moves logically from abstract legal theory (constitutional foundations, natural law) to concrete application (the cannabis vignette), making complex legal concepts accessible without oversimplifying them.
- The use of a specific hypothetical vignette grounded in real Idaho and Montana law gives the argument practical weight and illustrates the human cost of unresolved legal conflicts.
- Direct quotations from authoritative sources—Black's Law Dictionary, the Cornell Law School Legal Information Institute, and the Supremacy Clause itself—lend credibility and demonstrate appropriate engagement with primary and secondary legal materials.
Key academic technique demonstrated
The paper effectively uses the "general-to-specific" organizational technique: it first establishes a broad conceptual framework (the hierarchy and types of U.S. law), then narrows to a precise legal mechanism (conflict of laws and the Supremacy Clause), and finally applies those principles to a concrete, socially relevant scenario. This layered approach is a hallmark of competent undergraduate legal writing.
Structure breakdown
The paper is organized into five sections. The introduction frames the purpose and scope. The second section surveys the major sources of law in hierarchical order. The third section analyzes how laws interact, including the resolution of conflicts through classification and the Supremacy Clause. The fourth section presents a hypothetical client scenario to illustrate federal-state cannabis conflict. The conclusion synthesizes the key findings and advocates for legal harmonization.
Introduction
Today, most Americans are rightfully proud of the fact that the United States is a land of laws, but many may not realize the multiple sources of the laws that routinely affect their daily lives (Lupu, 2013). The purpose of this paper is to provide a description of the major sources of law under the American system of jurisprudence and how these different sources of law either complement or conflict with one another. In addition, a hypothetical vignette describing a potential conflict between federal and state law concerning the possession of medical cannabis products in Idaho is presented, followed by a summary of the research and important findings in the conclusion.
