In the March 3, 2026, Texas Republican primary, Proposition 10 received 94.81% support from Republican voters. The proposition asked whether Texas should prohibit Sharia law in Texas courts. While the vote itself is non-binding, such overwhelming support sends a powerful signal about the priorities of Republican primary voters and may influence the legislative agenda heading into the 90th Texas Legislature in 2027.
But before lawmakers rush to file new legislation, a more fundamental question should be asked: Does Texas actually need a new law to prohibit Sharia law?
A careful look at existing statutes, the Texas Constitution, and the U.S. Constitution suggests that much of what Proposition 10 calls for is already addressed under current law. The real issue may not be a lack of legal authority, but rather clarity and enforcement of existing protections.
The Role of Primary Ballot Propositions
Primary ballot propositions in Texas do not create law. Instead, they function as policy surveys of party voters, allowing activists, party leadership, and legislators to gauge grassroots priorities.
Historically, these advisory propositions can significantly shape legislative debates. A recent example is the school choice proposition in the 2022 Republican primary. Republican voters overwhelmingly supported allowing parents to use state education funds for alternative schooling options.
That vote did not immediately change the law, but it profoundly influenced the 88th Texas Legislature in 2023. School choice legislation became one of the most heavily debated issues of the session. Numerous bills were filed, and the issue dominated legislative strategy, special sessions, and primary challenges to incumbents.
The primary vote demonstrated strong grassroots demand for education reform and created political pressure for legislators to address the issue. Even though school choice did not pass during the 88th Legislature, the issue remained central to Texas politics and greatly influenced the education reform enacted in the 89th Legislature (2025).
Proposition 10 could create a similar dynamic. A 94.81% vote is not merely a majority. It represents near unanimity among Republican primary voters, the very electorate that determines Republican nominations in Texas.
For legislators in safe Republican districts, ignoring such a signal can carry political risk.
Texas Law Already Limits Foreign Legal Systems
Despite the strong political message from Proposition 10, Texas already has laws that address the core issue.
In 2017, the Texas Legislature passed House Bill 45 (HB 45), authored by former State Rep. Dan Flynn (R-Van), which prevents Texas courts from applying or enforcing foreign laws, including religious legal systems, if doing so would violate constitutional rights guaranteed under the U.S. Constitution, the Texas Constitution, or public policy.
If a legal claim relies on foreign law that conflicts with these protections, Texas courts must refuse to enforce it.
This legislation was part of a broader national movement sometimes referred to as “American Laws for American Courts.” The goal was not to target a specific religion, but to ensure that constitutional protections remain supreme within the American legal system.
Constitutional Protections Already Conflict With Sharia Law
Even without HB 45, several constitutional provisions would prevent the enforcement of Sharia law in American courts.
Equal Protection
The Fourteenth Amendment to the U.S. Constitution guarantees equal protection under the law. Certain interpretations of Sharia law treat men and women differently in matters such as inheritance, testimony, and family law. Any attempt to enforce such rules in a Texas court would violate constitutional protections against discrimination.
Due Process
The Fifth and Fourteenth Amendments guarantee due process rights in legal proceedings. American courts require standardized legal procedures, impartial judges, and predictable rules of evidence. Legal systems that impose judgments outside these protections cannot be enforced.
Religious Establishment
The First Amendment’s Establishment Clause prohibits the government from establishing or enforcing a religious legal system. Civil courts cannot operate under religious law without violating this constitutional principle.
The Texas Constitution contains similar protections for religious liberty, equal rights, and due process.
Taken together, these provisions ensure that American constitutional law, not religious law, governs civil courts in Texas.
Why the Issue Still Resonates Politically
If existing law already addresses the issue, why did Proposition 10 receive such overwhelming support?
Part of the answer lies in public concern about enforcement and clarity. Over the past several years, controversies have emerged in Texas regarding allegations of private arbitration systems or residential developments that could potentially operate under religious legal rules.
In response to those concerns, the Texas Legislature and Governor Greg Abbott have taken steps to reinforce existing legal protections. For example, recent legislation has targeted attempts to establish housing communities governed by legal systems that conflict with state law.
These actions illustrate an important reality. The legal framework already exists, but policymakers occasionally revisit the issue when new circumstances raise questions about enforcement.
What the 90th Texas Legislature Might Do
Given the overwhelming support for Proposition 10, lawmakers in the 90th Texas Legislature may still pursue legislation related to the issue. However, such legislation should likely fall into one of several categories.
Clarifying Existing Statutes
Lawmakers may introduce bills that clarify how existing laws apply to arbitration agreements, foreign legal contracts, or family law disputes.
Strengthening Enforcement
The legislature could create additional enforcement mechanisms to ensure that courts and local governments comply with existing statutes prohibiting the enforcement of foreign laws that violate constitutional rights.
Symbolic Legislation
Some legislation may simply reaffirm the principle that Texas courts operate exclusively underconstitutional law. While such measures may not dramatically change the legal landscape, they often serve to reassure voters that lawmakers are responding to public concerns.
Legislative Oversight
Committees may also conduct hearings to review whether current laws are being properly enforced and whether additional guidance is needed for courts or local governments.
Enforcement Versus New Legislation
The central question raised by Proposition 10 is not whether Sharia law should govern Texas courts. Under existing law and constitutional principles, it already cannot.
The more relevant question for policymakers is whether the current legal framework is adequately enforced and clearly understood.
Texas already has:
- Constitutional protections guaranteeing equal rights and due process
- Statutes preventing the enforcement of foreign laws that violate constitutional rights
- Long-standing court doctrines that reject contracts or arbitration agreements contrary to public policy
Because of these protections, the issue facing the legislature may be less about creating new legal prohibitions and more about ensuring that existing law is applied consistently and transparently.
A Political Signal More Than a Legal Gap
The 94.81% vote for Proposition 10 represents a powerful political signal from Republican primary voters. Like the school choice proposition in 2022, it will likely influence legislative debates and campaign messaging heading into the next legislative session.
But when it comes to the actual legal framework governing Texas courts, the evidence suggests that the foundation is already in place.
For lawmakers in the 90th Texas Legislature, the challenge may not be writing entirely new laws, but rather demonstrating that Texas courts remain firmly anchored to the principles of the U.S. Constitution and the Texas Constitution.
