Whether the FTCA's discretionary-function exception bars claims based on the government's decisions to create the fertilizer program and establish its production, packaging, labeling, and shipping specifications.
Holding
Yes. Section 2680(a) bars these claims because the challenged decisions were discretionary policy and planning judgments.
Reasoning
The FTCA waives immunity only for specified negligent or wrongful acts, and its waiver is expressly limited by exceptions. Section 2680(a) excludes claims based on the exercise or failure to exercise a discretionary function or duty, even when the discretion is abused. The Court read the provision in light of its text and legislative history, which showed that Congress did not intend tort suits to test the wisdom or negligent execution of authorized governmental programs and administrative judgments.
The protected discretion is not confined to the Cabinet-level choice to undertake a program. It also reaches executive and administrative determinations made in establishing plans, specifications, and schedules of operation. Where officials have room to exercise policy judgment in selecting a course of action, the discretionary-function exception applies; otherwise, a plaintiff could evade the exception merely by challenging a subordinate's implementation of a superior's authorized plan.
The alleged negligence in manufacturing FGAN was inseparable from the government's plan. The specifications governing the PRP coating, bagging temperature, paper bags, and product labels were adopted through expert judgment informed by TVA experience, industry practice, production needs, costs, and the known characteristics of FGAN. Those choices involved balancing safety, feasibility, and the practical success of the foreign-fertilizer program, not merely routine operational carelessness.
The Court also found no demonstrated knowledge of a probable danger sufficient to make these planning judgments actionable. FGAN had been produced and shipped for years without a comparable accident, and the evidence did not establish that officials knew it would likely ignite or explode when handled as it was here. The Court therefore treated the asserted failures to conduct further tests or use different specifications as discretionary determinations insulated by § 2680(a).
