The United States legal system comprises multiple federal circuits, each responsible for handling appeals and cases from a specific geographical region.

Let us delve into what you need to know about the 9th Circuit Court, including its jurisdiction, history, notable cases, and its impact on IRS tax-related matters.

Understanding the 9th Circuit Court

Judges in the 9th Circuit are appointed for life by the President of the United States and confirmed by the Senate.

History of the 9th Circuit Court

A. Formation

The 9th Circuit Court's history dates back to the Judiciary Act of 1891, also known as the Evarts Act. This legislation restructured the federal courts and established the system of circuit courts of appeals to relieve the workload of the U.S. Supreme Court. The 9th Circuit was initially created to cover a vast geographical area of the western United States.

B. Growth and Reorganization

Over the years, the 9th Circuit Court's jurisdiction expanded due to the growth of the western states. It was reorganized and split into the 9th and 10th circuits in 1929. However, this division was short-lived, and the 9th Circuit regained its current configuration in 1948.

C. Impactful Cases

Throughout its history, the 9th Circuit has been involved in numerous landmark cases that have shaped American jurisprudence. Notable cases include decisions related to civil rights, environmental law, immigration, and taxation.

The 9th Circuit Court's Impact on IRS Tax-Related Matters

The 9th Circuit Court plays a pivotal role in interpreting federal tax laws and regulations, particularly in cases where taxpayers challenge the IRS's actions or policies. Here are key aspects of the 9th Circuit's involvement in IRS tax-related matters:

  • Tax Litigation: The 9th Circuit Court handles a significant number of tax-related cases, including disputes between taxpayers and the IRS. These cases can involve issues such as tax liability, deductions, credits, penalties, and more.

  • Tax Fraud and Evasion Cases: The 9th Circuit has heard tax fraud and evasion cases. In these cases, individuals or entities accused of fraudulent or evasive tax practices may appeal their convictions or penalties to the circuit court.

  • Tax Treatment of Income: One of the critical roles of the 9th Circuit is interpreting the tax treatment of various types of income. This includes determining whether income is subject to taxation, whether it qualifies for specific tax credits or deductions, and how it should be reported on tax returns.

  • Environmental Tax Matters: The 9th Circuit Court has often handled tax-related matters tied to environmental issues, such as tax incentives for renewable energy projects, conservation easements, and taxation of natural resource extraction.

  • Tax Appeals and Procedural Matters: The circuit court hears appeals related to tax cases decided by federal tax courts and lower federal courts. Additionally, it deals with procedural issues related to tax cases, such as jurisdictional matters and challenges to IRS enforcement actions.

Notable Cases Heard by the 9th Circuit Court

  • California v. Trump (2019): In this high-profile case, the 9th Circuit Court ruled on a challenge to the Trump administration's decision to divert federal funds from military construction projects to fund the construction of a border wall. The case had significant budgetary implications and touched on issues of executive authority.

  • United States v. Hom (2017): This case involved the IRS's ability to collect taxes on a taxpayer's foreign income. The 9th Circuit ruled that the taxpayer could not avoid U.S. taxation on foreign income by simply keeping the funds offshore.

  • Altera Corporation v. Commissioner of Internal Revenue (2019): This case revolved around transfer pricing regulations and whether the IRS could require U.S. companies to include stock-based compensation costs in their cost-sharing agreements with foreign subsidiaries. The 9th Circuit ruled in favor of the IRS, upholding the agency's authority to issue such regulations.

  • Hawai'i Wildlife Fund v. County of Maui (2018): This environmental case had tax implications related to municipal wastewater treatment. The 9th Circuit ruled that discharges from wastewater treatment facilities that reach the ocean via groundwater can be subject to the Clean Water Act, potentially impacting taxation and compliance for municipalities.

  • Bullock v. Internal Revenue Service (2015): This case involved the discharge of tax debt through bankruptcy. The 9th Circuit addressed whether taxes that were not assessed before a taxpayer filed for bankruptcy could still be discharged. The ruling clarified the dischargeability of certain tax debts in bankruptcy proceedings.

The Role of Precedent in the 9th Circuit

Like other federal circuit courts, the 9th Circuit places great importance on precedent or legal decisions that serve as authoritative examples for future cases. Precedent helps maintain consistency and predictability in the application of federal law. When the 9th Circuit issues a ruling on an IRS tax-related matter, it establishes a precedent that can influence how similar cases are decided within its jurisdiction.

Criticisms and Controversies

The 9th Circuit Court is not without its share of criticisms and controversies. Some critics argue that the court leans liberal in its rulings, while others point to its size and caseload as factors that contribute to delays in rendering decisions. Additionally, the court's expansive jurisdiction over nine states can make it challenging for judges to fully understand each region's unique legal and cultural nuances.


The 9th Circuit Court of Appeals plays a crucial role in interpreting federal law, including IRS tax-related matters, within its vast geographical jurisdiction. It has a rich history of handling complex cases and has issued decisions that have profoundly impacted American jurisprudence. Whether you are a taxpayer, legal professional, or simply interested in the workings of the federal judiciary, understanding the 9th Circuit's role and influence is essential for navigating the complexities of the U.S. legal system.
