Common questions
Frequently Asked
4
What distinguishes a discretionary function from a ministerial act?+
A discretionary function involves judgment or policy choice by a government employee or agency. A ministerial act follows a specific directive or rule with no room for choice. The distinction determines whether the Federal Tort Claims Act exception applies.
Does the discretionary function exception protect even when discretion is abused?+
Yes. The Federal Tort Claims Act expressly states that the exception applies whether or not the discretion involved is abused. This prevents courts from second-guessing policy judgments regardless of outcome.
How does the discretionary function principle affect presidential aides' immunity?+
Presidential aides receive absolute immunity only when performing discretionary functions in sensitive areas of national concern closely tied to presidential decision-making. Otherwise they receive only qualified immunity that shields them unless they violate clearly established rights.
Can private contractors claim protection under the discretionary function principle?+
Private contractors may receive derivative immunity when they comply with reasonably precise government specifications that involve discretionary judgments. The protection applies when the government itself would be immune for the same discretionary choice.
