This article is the second in a series.

When the federal government detains someone, it takes responsibility for that person’s safety. If officers wrongfully detain someone, use force, deny medical care, or allow a death in ICE custody, the key legal question is not whether the policy was controversial. Instead, the question is whether the conduct violated enforceable duties under the Federal Tort Claims Act (FTCA).

In this article, we explain one of the most common defenses in these cases:

The Discretionary Function Exception.

If you litigate under the FTCA, you will see this defense early. You will also see it often. The government raises it in many cases, usually in a motion to dismiss.

Because of that, you need to understand how it works.

What Is the Discretionary Function Exception?

The FTCA waives sovereign immunity in limited situations. However, Congress created several exceptions.

One of the most powerful is the Discretionary Function Exception (DFE).

In simple terms, the government argues:

“You cannot sue us for policy decisions grounded in judgment or discretion.”

Courts apply a two-step test.

Step One: Did the Conduct Involve Judgment or Choice?

First, courts ask whether the conduct involved judgment or choice.

If a rule required a specific action, the exception does not apply. However, if the employee had discretion, the analysis moves to step two.

Step Two: Was the Judgment Based on Public Policy?

Next, courts ask whether the judgment involved public policy considerations.

For example, courts look at decisions involving:

If both steps apply, courts will dismiss the claim.

Where the Government Overreaches

In ICE detention cases, the government often pushes the DFE too far.

The key distinction is simple:

For example, if ICE uses mandatory language like “shall,” officers must follow it. When they ignore those rules, they do not make a policy decision. They fail to do their job.

Common examples include:

Courts regularly draw this line. The government often tries to blur it.

Why Framing Matters

Framing can make or break the case.

Many complaints attack “bad policy.” That approach invites dismissal.

Instead, focus on specific failures:

In short, do not argue:  “They should not have adopted this policy.”

Instead, argue: “They failed to follow their own required rules.”

That difference often decides whether the case survives. 

Medical Neglect and Suicide Cases

In detention-related deaths, the DFE is frequently asserted.

But where mandatory intake screenings, suicide-watch requirements, monitoring protocols, or medical referral procedures exist, failure to follow them may fall outside the exception.

The key distinction remains:

Protected policy design vs. Failure to carry out required safety measures

That line matters.

Contractor Facilities and the DFE

The DFE often appears alongside the “independent contractor” defense.

The government may argue both:

  1. The facility was privately operated.
  2. Oversight decisions were discretionary.

Again, the analysis turns on specifics:

These are fact-intensive questions.

Bottom Line

The Discretionary Function Exception is powerful. But it is not unlimited.

In ICE and federal detention litigation, the outcome often turns on how precisely the claim is framed at the outset.

If the complaint attacks policy, it is vulnerable.

If it identifies specific mandatory duties that were violated, it has a stronger path forward.

If you believe someone was harmed in federal custody, early legal analysis matters. Discretionary Function issues are often decided before discovery begins.

Frequently Asked Questions About the Discretionary Function Exception

What is the Discretionary Function Exception under the FTCA?

The Discretionary Function Exception is a provision of the Federal Tort Claims Act that bars claims based on protected policy judgments made by federal employees. If the conduct involves discretionary decision-making grounded in public policy considerations, the claim may be dismissed.

Does the Discretionary Function Exception apply to ICE detention cases?

It is frequently raised in ICE and federal detention cases. However, it does not automatically apply. Courts distinguish between protected policy decisions and failures to follow mandatory procedures or established directives.

What is the difference between policy decisions and operational negligence?

Policy decisions typically involve balancing governmental priorities or allocating resources. Operational negligence involves failing to carry out required duties, such as ignoring mandatory medical screening, monitoring requirements, or use-of-force protocols.

Can a case be dismissed before discovery because of the DFE?

Yes. Courts often decide Discretionary Function issues at the motion to dismiss stage. Complaints must clearly identify violated mandatory directives and non-discretionary duties.

How do you plead around the Discretionary Function Exception?

The focus should be on specific mandatory requirements that were ignored. Broad attacks on policy design are more vulnerable to dismissal. Precision in framing matters.
