Appeals Court Lifts Ban on Student Loan Repayment Plan
By
Reviewed
By Harry William
Background
In August 2022, President Biden announced a plan to forgive up to $20,000 in federal student loans for eligible borrowers and extend the pause on federal student loan payments through December 31, 2022. However, a federal judge in Texas issued an injunction blocking the implementation of the loan forgiveness program, arguing that it was an unlawful exercise of executive authority.
Appeals Court Ruling
On December 29, 2022, a three-judge panel of the United States Court of Appeals for the Eighth Circuit lifted the injunction, allowing the Biden administration to move forward with the student loan forgiveness program. The court ruled that the plaintiffs, a group of states led by Texas, had not shown a likelihood of prevailing on their legal challenge to the program and that they would not suffer irreparable harm if the injunction were lifted.
Legal Arguments
The plaintiffs argued that the student loan forgiveness program violated the separation of powers doctrine by exceeding the executive branch’s authority. They claimed that the Higher Education Relief Opportunities for Students Act of 2003 (HEROES Act), which the Biden administration cited as legal authority for the program, did not provide the necessary authority to forgive student loans.
The court disagreed, finding that the HEROES Act “broadly authorizes” the Secretary of Education to modify loan terms and conditions “in order to ensure that borrowers are not placed in a worse position financially as a result of a national emergency.” The court noted that the COVID-19 pandemic had created a national emergency and that the student loan forgiveness program was a reasonable exercise of the Secretary’s authority to address the financial difficulties faced by borrowers.

Impact of the Ruling
The Eighth Circuit’s ruling is a significant victory for the Biden administration and for millions of student loan borrowers. The ruling clears the way for the administration to implement the student loan forgiveness program, which is expected to provide substantial financial relief to eligible borrowers.
The ruling is also a setback for the plaintiffs, who have vowed to continue their legal challenge to the program. The plaintiffs may appeal to the Supreme Court, which could ultimately decide the fate of the student loan forgiveness program.
Key Issues for Further Discussion
The Eighth Circuit’s ruling raises several important issues for further discussion, including:
- The limits of executive authority: The court’s ruling suggests a broader interpretation of executive authority under the HEROES Act. This could have implications for other actions taken by the Biden administration to address the COVID-19 pandemic and other national emergencies.
- The separation of powers: The plaintiffs’ legal challenge to the student loan forgiveness program was based on the separation of powers doctrine. The court’s ruling in favor of the Biden administration suggests that the courts may be less likely to intervene in executive actions that are based on statutory authority.
- The impact on student loan borrowers: The student loan forgiveness program is expected to provide substantial financial relief to millions of borrowers. However, the program is also likely to face further legal challenges, and it is possible that it could be overturned or modified.
Conclusion
The Eight Circuit’s ruling is a major development in the ongoing legal battle over the Biden administration’s student loan forgiveness program. The ruling allows the administration to move forward with the program, but the legal challenges are likely to continue. The ultimate fate of the program will likely be decided by the Supreme Court.

Student Loan Freeze Blocked: What Borrowers Need to Know Now
Many student loan borrowers were eagerly awaiting the implementation of the Biden administration’s SAVE program, designed to offer significant debt relief and more manageable repayment options. However, recent court rulings have blocked key provisions of the program, leaving borrowers in a state of uncertainty.
Student Loan Freeze Blocked: What Happened?
On June 24th, 2024, federal judges in Kansas and Missouri issued temporary injunctions halting key aspects of the Department of Education’s SAVE program. This program aimed to:
- Expand debt forgiveness: Cancel a significant portion of student loan debt for borrowers who meet specific income-driven repayment plan criteria.
- Adjust income-driven repayment plans: Lower monthly payments for borrowers enrolled in income-driven plans, making repayments more manageable for those struggling financially.
These provisions were challenged by Republican-led states who questioned the Department of Education’s authority to implement such a large-scale forgiveness program without congressional approval.
Understanding the SAVE Program and Court Challenges
The SAVE program was launched in late 2023 as a cornerstone of the Biden administration’s efforts to address the growing student loan crisis. The program promised to be the most affordable repayment option ever offered, potentially impacting millions of borrowers.
However, the legality of the program’s debt forgiveness component was always a concern. Critics argued that the Department of Education overstepped its authority by enacting such a large-scale forgiveness plan without congressional authorization. This legal ambiguity ultimately led to the court challenges that have now blocked the program’s key provisions.
Here’s a table summarizing the key points of the court ruling and its impact:
| Aspect | Details |
|---|---|
| Court Ruling | Blocked key provisions of Biden’s SAVE program including further loan forgiveness and income-driven repayment plan adjustments. |
| Affected Borrowers | Millions enrolled in the SAVE program, potentially impacting their monthly payments and debt forgiveness timeline. |
| Reason for Block | Legal challenges by Republican-led states questioning the Department of Education’s authority for such large-scale forgiveness. |
| Current Status | The Department of Education is reviewing the rulings and may appeal. Borrowers are still responsible for repayments after the previous pause ended. |
What Does the Block Mean for Borrowers?
For borrowers who were counting on the SAVE program for debt relief or lower monthly payments, this news is undoubtedly frustrating. The court rulings create uncertainty about the future of the program and potentially impact repayment plans for millions.
Here’s what borrowers should know in the immediate aftermath:
- Repayments are still due: The court block does not eliminate the requirement to resume student loan repayments after the previous COVID-era pause ended.
- Program status is unclear: It’s uncertain if or when the SAVE program’s provisions will be implemented. The Department of Education may appeal the rulings, but the process could take months or even years.
- Explore alternative options: While the SAVE program is on hold, borrowers should explore other repayment options to manage their student loan debt.

Alternative Repayment Options and Resources
The court block on the SAVE program shouldn’t leave you feeling powerless. Here are some alternative repayment options and resources to help you navigate this uncertain period:
- Income-Driven Repayment (IDR) Plans: These plans adjust your monthly payment based on your income and family size. While the SAVE program aimed to improve existing IDR plans, the current options can still provide significant relief for borrowers with financial hardship. Explore the Department of Education’s website (https://studentaid.gov/idr/) to learn more about IDR plans and determine if you qualify.
- Deferment and Forbearance: These programs allow you to temporarily postpone or reduce your monthly payments. Deferment applies if you meet specific criteria like enrollment in school or military service. Forbearance offers a more flexible option but may accrue interest on your unsubsidized loans. Utilize these options cautiously, as they should be temporary solutions, not long-term strategies.
- Loan Consolidation: Combining multiple federal loans into a single loan simplifies repayment and potentially qualifies you for a lower interest rate. However, consolidation locks you out of certain forgiveness programs, so weigh the pros and cons carefully.
- Refinancing: Explore private refinancing options that might offer lower interest rates than your current federal loans. Refinancing with a private lender eliminates your eligibility for federal benefits like income-driven repayment and forgiveness programs. Carefully consider this option and ensure the new loan terms are truly advantageous before refinancing.
Expert Insights: Navigating This Uncertainty
The recent court block on the SAVE program has undoubtedly caused anxiety for many student loan borrowers. To help you navigate this uncertain period, we spoke with Sarah Thompson, a certified financial planner specializing in student loan debt management. Here, Sarah shares her insights and advice:
Q: With the SAVE program on hold, what’s the most important step borrowers should take right now?
Sarah: The most crucial step is to proactively assess your current financial situation. Gather all your student loan documents and understand your total loan amount, interest rates, and repayment plan details. This knowledge empowers you to make informed decisions about managing your debt.
Q: What alternative repayment options should borrowers consider?
Sarah: Income-Driven Repayment (IDR) plans are a great starting point. They adjust your monthly payments based on your income, making them more manageable. Additionally, explore deferment and forbearance options if you’re facing temporary financial hardship. Remember, these are temporary solutions so have a plan to transition back to standard repayment when possible.
Q: Should borrowers consider loan consolidation or refinancing?
Sarah: Consolidation simplifies repayment by combining multiple loans, potentially lowering your interest rate. However, it locks you out of some forgiveness programs. Refinancing with private lenders might offer lower rates, but you lose federal benefits. Carefully evaluate your options and ensure the new terms are significantly better before refinancing.
Q: Is there any hope for the SAVE program, or should borrowers move on?
Sarah: The Department of Education might appeal the court ruling, but the process could be lengthy. It’s wise to focus on managing your debt with available options while staying informed about any updates on the SAVE program.
Q: Any additional advice for borrowers navigating this uncertainty?
Sarah: Absolutely! Develop a budget that prioritizes essential expenses and allocates funds for student loan repayments. There are also student loan forgiveness programs available for specific professions and public service careers. Research these options to see if you qualify. Finally, don’t hesitate to seek professional financial advice. A qualified advisor can create a personalized plan to tackle your student loan debt effectively.
By following these expert insights and taking proactive steps, you can navigate this period of uncertainty with a clear plan for managing your student loan debt. Remember, knowledge and proactive action are your best tools for tackling student loan challenges.
Conclusion
The court block on the SAVE program is a significant setback for student loan borrowers. However, it’s crucial to remember that you’re not powerless.
