The Federal Prosecutor's Field Manual: Sources of Law and the 27 Amendments

The Landscape and Hierarchy of Legal Authority

In the American legal system, a source of law is defined as the official origin from which legal rules derive their binding authority. For any legal argument to be valid, it must be grounded in an established source; opinion without such grounding is merely opinion. The internal hierarchy of these sources, organized from highest to lowest authority, is as follows:

U.S. Constitution: Ratified in $1788$ , it is the supreme law of the land. All other forms of law—including statutes, regulations, and executive orders—must conform to it. It establishes governmental structure, grants and limits powers, and protects individual rights. For example, if a state mandates church attendance, thus violating the $1^{\text{st}}$ Amendment's Establishment Clause, the law is rendered void.
Federal Statutes (U.S. Code): These are laws enacted by Congress and signed by the President, codified in the United States Code (U.S.C.). Under the Supremacy Clause (Art. VI), federal statutes override conflicting state laws. Notable examples include Title $18$ (crimes), Title $21$ (drugs), Title $26$ (taxes), and Title $42$ (civil rights). A specific application is $18$ U.S.C. § $1343$ (wire fraud), which allows an Assistant United States Attorney (AUSA) to charge a defendant for fraudulent investment schemes sent via email.
U.S. Constitution — Amendments: The $27$ amendments are also supreme law. They expand rights and modify governmental structure. The Bill of Rights (the first ten amendments) protects individual freedoms. For instance, if police search a home without a warrant, the $4^{\text{th}}$ Amendment requires a judge to exclude the evidence found.
Federal Regulations (Code of Federal Regulations): Rules issued by agencies such as the DEA, ATF, EPA, FDA, and SEC under authority delegated by Congress and codified in the CFR. These carry the force of law as long as the agency does not exceed its statutory boundaries. For example, an AUSA may charge a chemist with trafficking based on a DEA regulation that schedules a specific fentanyl analogue as a Schedule I substance.
Case Law (Judicial Decisions / Precedent): Published opinions that interpret existing laws, binding under the principle of stare decisis. Decisions from the U.S. Supreme Court bind all American courts, while $9^{\text{th}}$ Circuit decisions bind federal courts within that specific circuit. Case law fills gaps in silent or ambiguous statutes. In Riley v. California ( $2014$ ), the Supreme Court ruled that police must obtain a warrant to search a cell phone incident to arrest, establishing the law for all officers and courts.
State Constitutions: Each of the $50$ states possesses its own constitution. While conforming to the U.S. Constitution, state versions may grant broader rights. California's constitution, for example, provides express privacy protections in Article I, § $1$ , which may lead to the suppression of evidence that would have been admissible under federal $4^{\text{th}}$ Amendment standards.
State Statutes: Enacted by state legislatures, these are the primary source of criminal law in state courts. Examples include the California Penal Code, Evidence Code, Family Code, Probate Code, and Vehicle Code. California Penal Code § $187$ defines murder as the unlawful killing of a human being or fetus with malice aforethought, which a District Attorney (DA) would prosecute in Superior Court.
Treaties: Agreements with foreign nations ratified by $\frac{2}{3}$ of the Senate. Equal in authority to federal statutes under the Supremacy Clause, the later one in time generally controls in a conflict. Treaties govern things like international trade and extradition. For instance, an AUSA would use the mutual extradition treaty between the United States and Mexico to bring a drug cartel leader back to the U.S. for trial.
Executive Orders: Directives issued by the President for managing the executive branch. They carry the force of law but cannot override the Constitution or federal statutes. They can be rescinded by subsequent presidents. An example is a presidential directive to AUSAs to prioritize violent crime over certain drug offenses; this changes enforcement focus without creating or eliminating crimes.
Local Ordinances: Laws created by city councils or county boards regarding local matters like zoning, noise, or public health. These are prosecuted by city attorneys or county counsel. An example is a Los Angeles City Council ordinance banning smoking within $20$ feet of a restaurant entrance.
Common Law (Judge-Made Law): Principles developed by courts over centuries to fill gaps where no statute exists. Inherited from English common law, it still governs areas of contract, tort, and property law unless a legislature enacts a statute that overrides it. An example is applying common law fiduciary duty to a case where a business partner takes company funds, but no specific state statute covers the act.

The Seven Original Articles of the U.S. Constitution

Ratified in $1788$ , the original seven articles define the structure of the American government and the specific powers and limits of the federal authority.

Article I: The Legislative Branch Establishes Congress, comprised of the Senate and House of Representatives. Section $8$ lists "enumerated powers" such as taxing, borrowing, regulating commerce, and declaring war. It includes the "Elastic Clause" (the power to make laws "necessary and proper"). Section $9$ prohibits certain actions, including the suspension of habeas corpus (except in rebellion), ex post facto laws, and bills of attainder. For prosecutors, the Commerce Clause is the basis for statutes like the Controlled Substances Act, as upheld in Gonzales v. Raich ( $2005$ ).

Article II: The Executive Branch Establishes the Presidency and the President's roles as commander-in-chief, primary negotiator of treaties, and nominator of federal judges and officers. The President's duty is to "take care that the laws be faithfully executed." An AUSA's authority flows from the President through the Attorney General and the U.S. Attorney, all of whom are Article II appointees.

Article III: The Judicial Branch Creates the Supreme Court and grants Congress the power to create inferior courts (district and circuit courts). It grants federal judges life tenure and salary protection to ensure impartiality. It also narrowly defines treason. Every federal courtroom where an AUSA practices is an Article III court.

Article IV: Relations Between States The Full Faith and Credit Clause requires states to recognize the judicial proceedings of other states. The Extradition Clause requires the return of fugitives to the state where the crime occurred. It also guarantees every state a republican form of government and mandates that states not discriminate against citizens of other states (Privileges and Immunities).

Article V: The Amendment Process Defines the difficult two-step process for constitutional change: (1) Proposal by $\frac{2}{3}$ of both houses of Congress or a convention called by $\frac{2}{3}$ of state legislatures; and (2) Ratification by $\frac{3}{4}$ ( $38$ of $50$ ) of the states. The $26^{\text{th}}$ Amendment was the fastest to be ratified, taking fewer than $100$ days.

Article VI: The Supremacy Clause Mandates that the Constitution, federal laws, and treaties are the supreme law of the land, binding all state judges. It requires a constitutional oath for officials and prohibits any religious test for public office. This clause allows an AUSA to prosecute federal marijuana offenses even in states where the substance is legal under state law.

Article VII: Ratification Established that the Constitution would take effect upon ratification by $9$ of the $13$ original states. Delaware was the first to ratify in December $1787$ , and New Hampshire was the ninth in June $1788$ . Rhode Island was the final state to ratify in May $1790$ .

The Bill of Rights: Amendments 1 Through 10

Ratified on December $15$ , $1791$ , these first ten amendments protect individuals from federal government overreach.

$1^{\text{st}}$ Amendment (Religion, Speech, Press, Assembly, Petition) This amendment contains the Establishment Clause and Free Exercise Clause. Freedom of speech is not absolute; it excludes true threats, incitement (Brandenburg v. Ohio, $1969$ ), fraud, obscenity, and defamation. A prosecutor might charge a defendant under $18$ U.S.C. § $875$ for sending emails threatening a federal judge's life, as true threats are not protected.

$2^{\text{nd}}$ Amendment (Right to Bear Arms) Protects an individual's right to possess firearms (Heller, $2008$ ), but allows for regulation of protected classes. Felons and domestic violence misdemeanants are lawfully prohibited from possession under $18$ U.S.C. § $922(g)$ . Post-Bruen ( $2022$ ), these regulations are frequently challenged based on historical tradition.

$3^{\text{rd}}$ Amendment (Quartering of Soldiers) Prohibits the government from forcing citizens to house soldiers in their homes during peacetime without consent. While rarely litigated, it reinforces the principle of the home as a sanctuary from government intrusion.

$4^{\text{th}}$ Amendment (Search, Seizure, and Privacy) Protects against unreasonable searches and seizures, requiring warrants based on probable cause. It is enforced via the Exclusionary Rule (Mapp v. Ohio, $1961$ ). Key doctrines include reasonable expectation of privacy (Katz), Terry stops, and the automobile exception. Prosecutors must be expert in warrant exceptions like consent and exigent circumstances.

$5^{\text{th}}$ Amendment (Grand Jury, Double Jeopardy, Self-Incrimination, Due Process, and Takings) Requires a grand jury for federal felonies and prohibits double jeopardy (though the "dual sovereignty" doctrine allows separate state and federal prosecutions for the same act). It protects the right to remain silent (Miranda) and mandates Due Process, which is the source of the prosecutor's "Brady obligation" to disclose exculpatory evidence. It also requires just compensation for government property seizures.

$6^{\text{th}}$ Amendment (Counsel, Speedy Trial, Jury, and Confrontation) Guarantees six essential trial rights: (1) Speedy Trial (federal limit is $70$ days); (2) Public Trial; (3) Impartial Jury (protects against Batson violations); (4) Notice of charges; (5) Confrontation Clause (Crawford v. Washington, $2004$ , which limits testimonial hearsay); and (6) Right to effective counsel (Gideon and Strickland).

$7^{\text{th}}$ Amendment (Jury Trial in Civil Cases) Guarantees the right to a jury in federal civil cases where the value exceeds \text$20. It is not incorporated against the states. In asset forfeiture cases—which are civil proceedings against property—claimants often demand jury trials under this amendment.

$8^{\text{th}}$ Amendment (Bail, Fines, and Punishment) Prohibits excessive bail, excessive fines (Bajakajian, $1998$ ), and cruel and unusual punishment. Salerno ( $1987$ ) allows for preventive detention if a defendant is a danger to the community. Sentencing must meet "evolving standards of decency," such as the ban on executing the intellectually disabled (Atkins) or juveniles (Roper).

$9^{\text{th}}$ Amendment (Rights Retained by the People) States that the list of rights in the Constitution is not exhaustive. This is the foundation for unenumerated rights, such as the right to marital privacy established in Griswold v. Connecticut ( $1965$ ).

$10^{\text{th}}$ Amendment (Reserved Powers) Establishes federalism by reserving all powers not delegated to the federal government to the states or the people. In Printz v. United States ( $1997$ ), the Supreme Court ruled that Congress cannot "commandeer" state officers to enforce federal programs, such as background checks for handgun purchases.

Reconstruction Era Amendments: 11 Through 15

Ratified between $1795$ and $1870$ , these amendments addressed the aftermath of the Civil War and issues of state sovereignty.

$11^{\text{th}}$ Amendment (Sovereign Immunity of States) Ratified in $1795$ , it prevents states from being sued in federal court by citizens of other states or foreign nations without the state's consent. Individual officers, however, can be sued for injunctive relief or under § $1983$ .

$12^{\text{th}}$ Amendment (Presidency/VP Electoral Votes) Ratified in $1804$ after a tie in the $1800$ election necessitated $36$ ballots by the House to elect Thomas Jefferson over Aaron Burr. It requires electors to cast separate ballots for President and Vice President. This amendment is critical for prosecutors handling election-related interference or obstruction of official proceedings.

$13^{\text{th}}$ Amendment (Abolition of Slavery) Ratified in $1865$ , it abolished slavery and involuntary servitude except as punishment for a crime. It provides the constitutional authority for Congress to legislate against human trafficking, resulting in statutes like $18$ U.S.C. § $1589$ (forced labor) and § $1590$ (human trafficking).

$14^{\text{th}}$ Amendment (Citizenship, Due Process, Equal Protection) Ratified in $1868$ , it is the most litigated amendment. It grants birthright citizenship, incorporates the Bill of Rights against the states via the Due Process Clause, and mandates Equal Protection. It is the basis for civil rights prosecutions under $18$ U.S.C. § $242$ and serves as the legal foundation for cases like Brown v. Board, Loving, and Obergefell.

$15^{\text{th}}$ Amendment (Voting Rights and Race) Ratified in $1870$ , it prohibits denying the right to vote based on race, color, or previous condition of servitude. It is the basis for the Voting Rights Act of $1965$ . Enforcement was weakened by Shelby County v. Holder ( $2013$ ), which struck down the preclearance formula.

Modern Amendments: 16 Through 27

Ratified between $1913$ and $1992$ , these amendments reflect the growth and reform of the modern American state.

$16^{\text{th}}$ Amendment (Federal Income Tax) Ratified in $1913$ , it authorized Congress to collect taxes on income without regard to census enumeration. This funds the IRS and the entire federal infrastructure. AUSAs utilize this amendment to charge tax evasion ( $26$ U.S.C. § $7201$ ), most famously used to convict Al Capone when other crimes could not be proven.

$17^{\text{th}}$ Amendment (Direct Election of Senators) Ratified in $1913$ , it moved the selection of Senators from state legislatures to a direct popular vote to reduce corruption. It gives governors the power to make appointments for vacancies until a special election is held—a provision involved in the public corruption case of Governor Rod Blagojevich.

$18^{\text{th}}$ Amendment (Prohibition) Ratified in $1919$ , it prohibited the manufacture, sale, and transport of intoxicating liquors. It is considered a failure as it fostered an organized crime infrastructure. Its legacy includes the eventual development of the RICO statute ( $18$ U.S.C. § $1961$ – $1968$ ) to dismantle those criminal networks.

$19^{\text{th}}$ Amendment (Women's Suffrage) Ratified in $1920$ after a $72$ -year movement starting at Seneca Falls in $1848$ , it guarantees that the right to vote cannot be denied on account of sex.

$20^{\text{th}}$ Amendment (Term Start Dates) Ratified in $1933$ , it moved the presidential inauguration to January $20$ at noon and the start of congressional sessions to January $3$ . This reduced the "lame-duck" period. This constitutional timeline is highly relevant to the prosecution of events surrounding the certification of elections.

$21^{\text{st}}$ Amendment (Repeal of Prohibition) Ratified in $1933$ , it is the only amendment to repeal another ( $18^{\text{th}}$ ). Section $2$ gives states broad authority to regulate alcohol within their borders, including the right of counties (e.g., in Kansas) to remain dry.

$22^{\text{nd}}$ Amendment (Presidential Term Limits) Ratified in $1951$ following FDR's four terms, it limits a President to serving a total of two four-year terms (or a maximum of $10$ years total if succeeding mid-term). It prevents the entrenchment of executive power.

$23^{\text{rd}}$ Amendment (D.C. Electoral Votes) Ratified in $1961$ , it granted citizens of Washington D.C. the right to vote in presidential elections by allocating them $3$ electoral votes (matching the least populous state).

$24^{\text{th}}$ Amendment (Abolition of Poll Taxes) Ratified in $1964$ , it prohibited poll taxes in federal elections. Harper v. Virginia ( $1966$ ) later extended this to state elections. It eliminated a major tool of voter suppression utilized against Black voters.

$25^{\text{th}}$ Amendment (Presidential Succession and Disability) Ratified in $1967$ , it outlines procedures for filling VP vacancies (Section $2$ ) and declared presidential inability to serve (Section $4$ ). This was used when Spiro Agnew resigned, leading to Gerald Ford's nomination and subsequent elevation to President upon Richard Nixon's resignation.

$26^{\text{th}}$ Amendment (Voting Rights for 18-Year-Olds) Ratified in $1971$ in just $100$ days during the Vietnam War, it lowered the voting age from $21$ to $18$ . It resolved an administrative nightmare created by Oregon v. Mitchell ( $1970$ ), which had allowed different voting ages for state and federal elections.

$27^{\text{th}}$ Amendment (Congressional Pay) Originally proposed in $1789$ by James Madison, it was finally ratified in $1992$ —a gap of $203$ years. It prevents a pay raise for Congress from taking effect until an intervening election of Representatives has occurred. This is a crucial context when prosecuting congressional bribery cases under $18$ U.S.C. § $201$ .
