Decisive question

Does FIFRA preempt a state-law failure-to-warn claim that would require a cancer warning the EPA did not require?

Controlling dependency

Whether the state duty enforced a requirement parallel to the federal misbranding standard, or imposed an additional one the manufacturer could not lawfully satisfy.

Defeat condition

Proof that the state duty enforced the same federal requirement would have sustained the construction.

How it compared

Divergence. The determination correctly predicted that review was required and that a mature national conflict needed terminating, but did not predict the outcome. NLI published the reason: misframing by premature equivalence, assuming the duties were parallel because both broadly required adequate warnings, which reproduced the lower court’s own category error.

This is the clearest recorded failure in the set and is published for that reason. A record that reports only successes cannot be checked.

NLI’s role

Published analysis only. No participation in the case.

Limits of this record

NLI was not counsel, a party, or a participant in this case, and filed nothing in it. This record establishes only that NLI published the stated determination on the stated date and how that determination compared with the decision the Court later reached. It does not establish that NLI influenced the outcome, that NLI’s reasoning was adopted, or that a comparable result should be expected in any other matter.
