According to the Legal Information Institute at Cornell Law School, federalism is &#8220;a system of government in which the same territory is controlled by two levels of government.&#8221; Under this framework, the U.S. Constitution has established a system of &#8220;dual sovereignty,&#8221; where states have surrendered many powers to the federal government\u2014but have retained others.<\/p>\n\n\n\n<p>Three constitutional provisions form the backbone of this arrangement:<\/p>\n\n\n\n<p><strong>The Supremacy Clause (Article VI)<\/strong> declares that the Constitution, and all laws made under it, are &#8220;the supreme law of the land.&#8221; This means that when federal and state laws conflict, federal law wins. The Supremacy Clause also underpins the doctrine of federal preemption\u2014the principle that federal law can override state law in certain areas, either explicitly or by implication.<\/p>\n\n\n\n<p><strong>Article I, Section 8<\/strong> lists Congress&#8217;s specific legislative powers, known as enumerated powers. These include the authority to coin money, regulate interstate commerce, establish post offices, declare war, and raise a military. Congress also holds the Necessary and Proper Clause, which grants it authority to pass all laws &#8220;necessary and proper&#8221; for carrying out its enumerated functions.<\/p>\n\n\n\n<p><strong>The Tenth Amendment<\/strong> reserves to the states\u2014or to the people\u2014all powers not delegated to the federal government. This reservation clause protects state authority over areas like education, public safety, local courts, and business regulation within state borders.<\/p>\n\n\n\n<p>Together, these provisions create a layered system of governance that has been interpreted and refined through centuries of Supreme Court decisions. One landmark ruling, McCulloch v. Maryland (1819), established that Congress holds implied powers beyond its enumerated list. Chief Justice John Marshall held that &#8220;necessary&#8221; should be understood broadly\u2014meaning &#8220;conducive to&#8221; or &#8220;appropriate and legitimate&#8221;\u2014not strictly indispensable. His famous conclusion: &#8220;Let the end be legitimate, let it be within the scope of the constitution, and all means which are appropriate, which are plainly adapted to that end&#8230;are constitutional.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\"><strong>Exclusive vs. Concurrent Powers: Who Governs What?<\/strong><\/h2>\n\n\n\n<p>Powers under American federalism fall into three categories: those held exclusively by the federal government, those reserved for the states, and those shared by both.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-small-font-size\">Exclusive Federal Powers<\/h3>\n\n\n\n<p>These are powers only the national government can exercise. They include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Coining money and regulating currency<\/li>\n\n\n\n<li>Declaring war and maintaining a national military<\/li>\n\n\n\n<li>Regulating immigration and naturalization<\/li>\n\n\n\n<li>Establishing post offices<\/li>\n\n\n\n<li>Conducting foreign policy and ratifying treaties<\/li>\n<\/ul>\n\n\n\n<p>States are explicitly prohibited from exercising these powers. Article I, Section 10 of the Constitution bars states from coining money, entering into treaties, or granting titles of nobility, among other things.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-small-font-size\">Reserved State Powers<\/h3>\n\n\n\n<p>Under the Tenth Amendment, states retain authority over matters of local concern. These reserved powers include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Establishing and overseeing school systems<\/li>\n\n\n\n<li>Creating public safety and law enforcement systems<\/li>\n\n\n\n<li>Regulating business and trade within state borders<\/li>\n\n\n\n<li>Managing state court systems<\/li>\n\n\n\n<li>Administering local government<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-small-font-size\">Concurrent Powers<\/h3>\n\n\n\n<p>Some powers belong to both levels of government simultaneously. Concurrent powers include taxation, building roads, and creating lower courts. Both Congress and state legislatures can exercise these powers independently\u2014though the Supremacy Clause applies if a conflict arises.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\"><strong>Federalism and the Criminal Justice System<\/strong><\/h2>\n\n\n\n<p>Federalism directly shapes who prosecutes criminal offenses in the United States\u2014and under some circumstances, the same conduct can trigger both state and federal charges.<\/p>\n\n\n\n<p>Most criminal law in the United States originates at the state level. Crimes like assault, theft, murder, and drug possession are typically prosecuted under state statutes by state prosecutors. Each state maintains its own criminal code, court system, and sentencing guidelines.<\/p>\n\n\n\n<p>Federal criminal jurisdiction is narrower but significant. Congress has authority to criminalize conduct that involves:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Interstate commerce or activity crossing state lines (e.g., drug trafficking across state borders)<\/li>\n\n\n\n<li>Federal property or federal officials<\/li>\n\n\n\n<li>Violations of federal statutes (e.g., federal weapons charges, bank fraud, tax evasion)<\/li>\n\n\n\n<li>Activities governed by specific federal laws, such as immigration violations<\/li>\n<\/ul>\n\n\n\n<p>Because federal and state criminal laws operate independently, a single act can sometimes violate both. A person <strong><a href=\"https:\/\/www.delewislaw.com\/blog\/firearm-penalties-in-indianapolis-what-you-need-to-know\/\" target=\"_blank\" rel=\"noreferrer noopener\">caught carrying a firearm illegally<\/a><\/strong> may face charges under both state law and a separate federal firearms statute. Both prosecutions can proceed\u2014and courts have consistently upheld this framework.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\"><strong>How Dual Sovereignty Impacts Criminal Defense<\/strong><\/h2>\n\n\n\n<p>The dual sovereignty doctrine means that the Double Jeopardy Clause of the Fifth Amendment does not bar successive prosecutions by separate sovereigns\u2014a ruling the Supreme Court reaffirmed in Gamble v. United States (2019).<\/p>\n\n\n\n<p>The <strong><a href=\"https:\/\/www.delewislaw.com\/blog\/double-jeopardy-understanding-your-fifth-amendment-rights\/\" target=\"_blank\" rel=\"noreferrer noopener\">Double Jeopardy Clause<\/a><\/strong> states that no person shall be &#8220;twice put in jeopardy&#8230;for the same offence.&#8221; Many defendants assume this protection prevents both state and federal governments from prosecuting them for the same conduct. This assumption is wrong.<\/p>\n\n\n\n<p>In Gamble v. United States, the Supreme Court declined to overturn the dual sovereignty doctrine in a 7\u20132 decision authored by Justice Samuel Alito. The Court clarified that the doctrine is not an exception to the right against double jeopardy\u2014it is a corollary to the text of the Fifth Amendment itself. Because an &#8220;offence&#8221; is defined by law, and laws are created by a sovereign, conduct that violates both a state law and a federal law constitutes two separate offenses under two separate sovereigns.<\/p>\n\n\n\n<p>The practical result: a defendant acquitted under state law can still face federal prosecution for the same underlying conduct, and vice versa.<\/p>\n\n\n\n<p>Justices Ruth Bader Ginsburg and Neil Gorsuch dissented. Justice Gorsuch warned that the doctrine &#8220;endorses a colossal exception to this ancient rule against double jeopardy&#8221; and that it &#8220;appears nowhere in the text of the Fifth Amendment.&#8221; These dissents signal ongoing tension around this doctrine\u2014but it remains binding law.<\/p>\n\n\n\n<p>For anyone <strong><a href=\"https:\/\/www.delewislaw.com\/criminal-defense.php\" target=\"_blank\" rel=\"noreferrer noopener\">facing criminal charges<\/a><\/strong>, understanding how federal and state jurisdictions interact can be the difference between a manageable outcome and a devastating one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\"><strong>Frequently Asked Questions About Federalism<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Can a state law contradict federal law?<\/h3>\n\n\n\n<p>Technically, yes\u2014states can pass laws that conflict with federal statutes. However, under the Supremacy Clause, federal law takes precedence when a genuine conflict exists. State laws that directly contradict federal law can be struck down through the doctrine of federal preemption.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are implied powers, and why do they matter?<\/h3>\n\n\n\n<p>Implied powers are federal authorities not explicitly listed in the Constitution but recognized through the Necessary and Proper Clause. The McCulloch v. Maryland ruling established that Congress can use any means &#8220;appropriate and legitimate&#8221; to carry out its enumerated functions. This has allowed federal authority to expand significantly over time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I be prosecuted by both the state and federal government for the same crime?<\/h3>\n\n\n\n<p>Yes. Under the dual sovereignty doctrine affirmed in Gamble v. United States (2019), both a state government and the federal government can prosecute you for the same conduct without violating the Double Jeopardy Clause, because each prosecution is brought by a separate sovereign under separate laws.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is federal preemption?<\/h3>\n\n\n\n<p>Federal preemption occurs when a federal law overrides or displaces a state law in the same subject area. Preemption can be explicit (clearly stated in the federal statute) or implied (inferred from congressional intent or the scope of federal regulation).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which court handles federal criminal cases?<\/h3>\n\n\n\n<p>Federal criminal cases are heard in U.S. District Courts, which are the trial-level courts of the federal judiciary. State criminal cases are handled in state trial courts. Appeals follow separate tracks\u2014federal convictions are appealed through the federal circuit courts, while state convictions move through state appellate courts.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Quick Recap: Key Facts to Remember<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Federalism divides governing authority between the national government and the states<\/li>\n\n\n\n<li>The Supremacy Clause (Article VI) makes federal law the &#8220;supreme law of the land&#8221;<\/li>\n\n\n\n<li>Article I, Section 8 lists Congress&#8217;s enumerated powers; the Necessary and Proper Clause extends these through implied powers<\/li>\n\n\n\n<li>The Tenth Amendment reserves powers not delegated to the federal government to the states<\/li>\n\n\n\n<li>Concurrent powers (e.g., taxation, road-building) are shared by both levels of government<\/li>\n\n\n\n<li>Most criminal law is state law, but federal criminal jurisdiction covers interstate activity, federal property, and specific federal statutes<\/li>\n\n\n\n<li>The dual sovereignty doctrine, reaffirmed in Gamble v.

For individuals facing criminal charges, it shapes who prosecutes you, which laws apply, and what protections you can invoke. The dual sovereignty doctrine, in particular, means that a state outcome\u2014whether acquittal or conviction\u2014does not necessarily end your legal exposure.<\/p>\n\n\n\n<p><strong>If you or someone you know is facing criminal charges in Indiana, getting informed legal counsel early is critical.<\/strong> <strong><a href=\"https:\/\/www.delewislaw.com\/contact-us.php\" target=\"_blank\" rel=\"noreferrer noopener\">Schedule a free criminal case review<\/a><\/strong> with our criminal defense lawyers in Indianapolis today.
