In brief
Overview
Biotech crops have produced enormous benefits for the nation's farmers and consumers.
According to Garre, the district court issued a broad‑based injunction against planting a highly beneficial, genetically engineered alfalfa crop, and erred in two fundamental respects.
Background and question before the Court
According to Justice Ginsburg, the Court recognized that the district court violated NEPA by failing to prepare an Environmental Impact Statement (EIS).
What each side argues
Petitioners (Monsanto Company)
According to Stewart, petitioners argue that the Court should decide the case rather than defer to the ongoing EIS process.
Petitioners contend that the district court’s vacatur had the effect of undoing the deregulation of Roundup Ready alfalfa.
According to Mr. Garre, counsel for the petitioners argues that the injunction is unlawful and is causing immediate harm to farmers.
According to Mr. Garre, counsel further asserts that there is no evidence of cross‑pollination with hay and that the alleged harm is merely psychological objection to genetically engineered alfalfa.
Respondents (Geertson Seed Farms)
Respondents maintain that their proposed interim plan—allowing continued planting with protective measures—is fundamentally different from the action that triggered the EIS.
What happened at oral argument
According to Chief Justice Roberts, chief Justice Roberts inquired whether the respondents were obligated to meet the injunction standards for the elements of the injunction that fell short of remand to the agency.
According to Justice Ginsburg, justice Ginsburg questioned whether a simple vacatur of the deregulation decision—making Roundup Ready alfalfa a regulated article again—would be sufficient.
Justice Kennedy asked whether the alleged harm to organic farming alone was sufficient to justify an injunction.
According to Justice Alito, justice Alito posed a question to counsel regarding Mr. Robbins’ arguments.
According to Chief Justice Roberts, chief Justice Roberts thanked counsel and noted that the case was submitted.
