When you’re injured because of a federal employee’s negligence, the Federal Tort Claims Act (FTCA) gives you a rare right: the ability to sue the United States for damages. But one of the most common—and dangerous—obstacles in these cases is something called the Discretionary Function Exception.

If the government successfully raises this defense, your claim can be dismissed even if you were clearly harmed by negligence. That’s why understanding this exception—and how to defeat it—is critical to maximizing your FTCA recovery.

At National Security Law Firm, our mission is simple: to fight back against unfair denials, overcome government defenses, and maximize every client’s settlement or judgment.


What Is the Discretionary Function Exception?

The Discretionary Function Exception (DFE) is a built-in limitation to the FTCA found in 28 U.S.C. § 2680(a). It bars lawsuits against the United States for:

“Any claim… based upon the exercise or performance or the failure to exercise or perform a discretionary function or duty… whether or not the discretion involved be abused.”

In plain English:
If the government employee was performing a function that involved judgment or choice grounded in public policy, the government may be immune—even if that decision caused harm.

This means the court won’t second-guess policy-based decisions like how to allocate resources, design safety programs, or prioritize inspections. But many agencies try to stretch this defense far beyond its purpose—using it as a catch-all shield for negligence.

That’s where strategy and experience matter.


The Two-Part Test: How Courts Determine Whether DFE Applies

The U.S. Supreme Court has established a two-step test (from Berkovitz v. United States and United States v. Gaubert) to decide whether the exception applies:

  1. Was the employee’s conduct discretionary?
    Did the action involve judgment or choice—or was it governed by a mandatory rule, regulation, or policy?
    If the employee was required to follow a specific directive and failed to, the DFE does not apply.

  2. Was the judgment based on public policy considerations?
    Even if the action involved discretion, it must also be the kind of decision that Congress intended to protect—i.e., grounded in social, economic, or political policy.
    Routine, operational negligence (like failing to maintain a vehicle or property safely) usually fails this prong.

If either prong is not met, the government cannot invoke the DFE.


Common Examples of When the Discretionary Function Exception Does Apply

  • Policy Decisions:
    Choosing how to allocate limited resources for road maintenance in a national park.

  • Design Choices:
    Selecting guardrail types, traffic control systems, or security screening protocols at airports.

  • Enforcement Discretion:
    Deciding how to monitor or enforce safety rules at federal facilities.


When the Exception Does Not Apply

Many government lawyers try to stretch the DFE to cover everything. But courts consistently reject it in cases involving negligence in carrying out mandatory duties or failure to perform basic operational tasks.

Examples include:

  • A postal truck accident caused by careless driving (not policy-based).

  • Medical malpractice at a VA hospital (professional judgment, not policy discretion).

  • Failure to follow a mandatory safety regulation or inspection checklist.

  • A maintenance worker’s failure to repair known hazards on federal property.

The key difference: policy-level discretion vs. operational negligence.

When the government’s conduct involves day-to-day carelessness—not policy-making—DFE doesn’t protect them.


How to Defeat the Discretionary Function Exception

Defeating DFE requires careful strategy and insider knowledge of how agencies operate. At National Security Law Firm, our FTCA attorneys—including former federal agency counsel—use a proven framework:

1. Identify Mandatory Policies or Regulations

We start by digging into agency manuals, internal SOPs, safety bulletins, and contracts. If a rule requires specific action (like inspecting a vehicle before operation or maintaining safe premises), we show the employee had no discretion.

2. Reframe the Conduct as Operational Negligence

We position the case as about how a task was carried out—not why it was done. This draws a sharp line between everyday negligence (not protected) and high-level policy discretion (protected).

3. Use FOIA to Uncover Evidence

Through targeted Freedom of Information Act (FOIA) requests, we often expose agency procedures or internal findings that contradict their DFE defense. These documents can prove the act was ministerial, not discretionary.

4. Challenge the Policy Connection

We argue that even if some discretion existed, it wasn’t policy-based. Neglecting maintenance or ignoring safety standards doesn’t involve weighing political or economic priorities—it’s simple negligence.

5. Leverage Expert Testimony

Experts can explain why the government’s actions were operational, not strategic—especially in cases involving medical care, engineering design, or safety protocols.


Case Example: When DFE Defense Failed

In Indian Towing Co. v. United States (1955), the Coast Guard negligently failed to maintain a lighthouse, causing a shipwreck. The government claimed immunity under DFE—but the Supreme Court disagreed, holding that once the government undertook to operate the lighthouse, it had a duty to maintain it with due care.

This landmark case established that once the government acts, it must do so safely.


Why It Matters

If the government can invoke the Discretionary Function Exception, your case can be dismissed before it ever reaches trial. But with the right strategy, you can:

  • Keep your case alive

  • Force the government to the negotiating table

  • Secure the full compensation you deserve

Every detail matters—from the wording in the SF-95 to the internal policies your attorney uncovers.
