The New Jersey Sports Betting Case That Changed U.S. Law
Meta description: Learn how Murphy v. NCAA, the New Jersey sports betting case, led the Supreme Court to strike down PASPA and let states decide whether to legalize sports betting.
A dispute over sports betting in New Jersey reshaped gambling law across the United States. In Murphy v. National Collegiate Athletic Association, the Supreme Court did not make sports betting legal nationwide. Instead, it struck down a federal law that restricted states from authorizing it. That constitutional ruling gave states—and Congress—room to determine what came next.
What Was the New Jersey Sports Betting Case?
The case is commonly called Murphy v. NCAA, after New Jersey Governor Phil Murphy and the National Collegiate Athletic Association, one of the organizations that challenged the state. The Supreme Court decided the case on May 14, 2018. Its central question was whether Congress could prevent states from changing their own laws to permit sports gambling.
The case grew out of New Jersey’s effort to offer sports betting at its casinos and racetracks. State officials argued that a federal prohibition limiting their options violated the Constitution’s division of power between the federal government and the states. The Supreme Court agreed, invalidating the federal law at issue.
The decision is important because it illustrates a constitutional principle called anti-commandeering: Congress generally cannot command state legislatures to enact, maintain, or administer a federal regulatory program. The ruling changed the legal landscape, but it did not require any state to allow wagering.
What Was PASPA?
The Professional and Amateur Sports Protection Act, known as PASPA, was enacted in 1992. It generally barred states and other government entities from sponsoring, operating, promoting, licensing, or authorizing sports gambling. The law included exceptions for a small number of places and activities, including certain forms of sports wagering that already existed or received specific treatment under the statute.
New Jersey was not among the states that could broadly offer sports betting under PASPA. The law did not simply create a federal licensing system for sportsbooks. Rather, it restricted state and local governments from authorizing the activity, while leaving much of the enforcement framework to state and federal authorities.
Congress described PASPA as a way to protect the integrity of sports and discourage the spread of sports gambling. Critics challenged its structure: instead of regulating private parties directly through a uniform federal system, PASPA limited what state governments could do. That distinction became central to the Supreme Court’s constitutional analysis.
How New Jersey Challenged the Law
New Jersey voters approved a state constitutional amendment in 2011 allowing the Legislature to authorize sports wagering at casinos and racetracks. The Legislature then passed a law to establish that authorization. The NCAA and several professional sports leagues sued, arguing that the state’s law violated PASPA. Federal courts agreed, and New Jersey lost its initial challenge.
In 2014, the state tried a different approach. Rather than creating a state-run sports betting program or issuing licenses under the challenged framework, it enacted a law that partially repealed state prohibitions on sports wagering at casinos and racetracks. The sports leagues sued again, arguing that PASPA prohibited this move as well. The case eventually reached the Supreme Court.
The procedural history mattered. The dispute was not simply whether New Jersey could open sportsbooks. It asked whether PASPA could forbid the state legislature from repealing its own laws. The Court examined whether that federal restriction crossed the constitutional line between regulating states and regulating private conduct.
What the Supreme Court Decided in Murphy v. NCAA
In a 6–3 decision, the Supreme Court held that PASPA’s restrictions on state authorization of sports gambling violated the anti-commandeering rule. Justice Samuel Alito wrote the majority opinion. The Court concluded that Congress cannot issue direct orders to state legislatures about whether to retain or repeal state-law prohibitions.
The Court rejected the idea that PASPA merely prohibited states from authorizing sports gambling while leaving them free to regulate it. In the majority’s view, telling a state that it may not change its laws in a particular way is also a form of control over the state legislature. The Constitution does not permit Congress to commandeer state lawmaking in that manner.
The Court also considered whether the problematic provisions could be separated from the rest of PASPA. It concluded that the provisions were not severable, so PASPA was invalidated as a whole. The ruling therefore removed the federal statutory barrier that had prevented states from authorizing sports betting under the law.
The decision did not hold that sports betting is a federally protected right. It did not require states to legalize gambling, establish a national sports betting regulator, or determine the details of state wagering rules. Those questions were left to lawmakers, subject to other applicable federal and state laws.
What Anti-Commandeering Means
Anti-commandeering is a federalism principle grounded in the Constitution’s structure. It limits the federal government’s ability to make states carry out federal policy. Congress may regulate private individuals and businesses when it has constitutional authority to do so, and it may offer states certain incentives. But it generally cannot simply order state legislatures or state officials to administer a federal regulatory scheme.
The Supreme Court had applied the principle in earlier cases, including New York v. United States (1992) and Printz v. United States (1997). Murphy extended the reasoning to PASPA’s restrictions on state legislation. The ruling’s significance therefore reaches beyond gambling: it clarified how Congress may—and may not—structure federal laws that affect state policy choices.
The decision did not mean federal law can never affect sports betting. Congress can legislate within its constitutional powers, and federal laws addressing matters such as interstate commerce, financial transactions, or criminal conduct may remain relevant. The ruling focused on PASPA’s particular command to state governments.
What Changed for States After the Ruling?
After PASPA fell, states could decide whether to authorize sports betting and how to structure it. Some moved quickly, while others chose not to legalize wagering or required additional legislative action. State approaches have varied in areas such as eligible locations, mobile betting, tax rates, licensing, permitted sports, and consumer protections.
New Jersey launched legal sports wagering in June 2018, shortly after the Supreme Court decision. Its casinos and racetracks became the foundation for a market that later included online and mobile betting. The state’s experience became a prominent example of how a jurisdiction could build a regulated market under its own laws.
Legalization has not followed one national template. A state may permit retail sportsbooks but restrict online wagering, allow mobile betting through licensed operators, or prohibit sports betting altogether. Tribal gaming arrangements, state constitutions, and local political decisions can also influence how a market is designed.
For an accurate, current picture, users should consult their state gaming regulator or official state government website. Rules and market availability change, and the presence of a sportsbook app does not necessarily mean that every type of bet is lawful in every location.
How State Sports Betting Laws Typically Work
When a state authorizes sports wagering, its law generally establishes which businesses may offer it and which agency will oversee them. Regulators can set licensing standards, audit requirements, advertising rules, and procedures for addressing complaints. Operators may also have to meet technical standards for account security and location verification.
Mobile betting usually depends on geolocation technology to confirm that a customer is physically within a jurisdiction where the wager is permitted. State rules may also require age checks, identity verification, and controls intended to detect suspicious betting activity. Specific requirements differ by jurisdiction and operator.
Consumer protections vary as well. Depending on state law, a regulator may require responsible-gambling information, self-exclusion options, limits on certain promotions, or a process for investigating disputes. These protections are not identical nationwide, so bettors should read local rules and account terms rather than assume that one state’s standards apply elsewhere.
| Issue | What It Means in Practice |
|---|---|
| Legal status | Each state decides whether to authorize sports betting within its jurisdiction. |
| Licensing | State regulators determine which operators may serve customers and under what conditions. |
| Mobile access | Online wagering is governed by state law and commonly uses location verification. |
| Consumer safeguards | Age checks, responsible-gambling rules, and complaint procedures vary by state. |
| Federal law | The Supreme Court invalidated PASPA, but other federal laws may still apply. |
What the Ruling Did Not Do
Several misconceptions persist about the New Jersey sports betting case. First, the Supreme Court did not legalize sports betting in all 50 states. It removed PASPA’s restriction on state authorization, leaving each state to decide whether to permit wagering.
Second, the ruling did not create a single national set of sportsbook rules. State legislatures and regulators set many of the practical requirements, which is why the legal age, permitted betting formats, tax treatment, and availability of mobile wagering can differ across state lines.
Third, Murphy did not eliminate every federal law that could apply to gambling businesses or transactions. It addressed PASPA’s specific limits on state action. Operators must still assess relevant federal, state, and local requirements, and a state’s authorization does not automatically resolve every legal question.
Finally, the decision did not guarantee that a state would collect revenue or that a market would succeed. Tax receipts, operator competition, enforcement costs, and public-health effects depend on local policy choices and market conditions.
Why the Case Still Matters
The practical effect of Murphy v. NCAA was a major expansion of state policymaking authority over sports betting. The case also demonstrated how constitutional structure can limit Congress even when lawmakers pursue a national policy goal. Rather than selecting a single rule for every state, the Court’s decision returned the authorization question to state political processes.
That shift has consequences for sports leagues, regulators, operators, and consumers. Leagues have developed integrity and data-related policies in a market that operates under different state laws. Regulators oversee licensed businesses, while operators must account for jurisdiction-specific requirements. Consumers encounter a patchwork of legal access and protections.
The broader lesson is that a Supreme Court ruling can change who has authority without dictating the final policy outcome. The Court removed a federal obstacle; it did not settle the debate over whether sports betting is beneficial, how it should be regulated, or how strongly its risks should be controlled.
