On December, 2010, APHIS released its final EIS, which found the RRAs substantially equivalent to non-GM alfalfas. Normally, such a finding of substantial equivalence would warrant deregulation. However, the USDA expressed its preference that deregulation of the RRAs be accompanied by safeguards to prevent genes from GM alfalfa from contaminating neighboring organic crops. The issue of colliding GM and non-GM crops has already reached the courts on several occasions, most notably in In re Starlink Corn Products Liability Litigation (N.D. Illinois 2002) and Monsanto v. Schmeiser (Supreme Court of Canada 2004). Like the English Railway Fires Acts, which were intended to provide modest compensation to owners (often farmers) whose lands were damaged by sparks from steam engines, while simultaneously preventing tort liability from discouraging the perceived economic progress offered by railways, the PPA deregulation pathway could become a method of encouraging the expansion of GM crops. The decision by APHIS to deregulate, but only with potentially onerous conditions, has even raised the ire of, among others, the Wall Street Journal, which led its December 27, 2010, editorial page with an indictment of USDA's decision to rely on non-scientific factors alongside scientific ones. The editorial warns that "[i]f nonscience criteria are introduced as considerations for allowing the sale of biotech crops, the effect would be disastrous for the USDA's regulatory reputation."
If GM crops continue to be rapidly adopted around the world, legal issues involving colliding crops are sure to become more common. Managing the legal consequences of such collisions awaits solutions.
