From the introduction on p.10:
"The Genetically Engineered Foods Mandatory Labeling Initiative (A.G. File No. 11-0099 – hereinafter the Initiative) would have a substantial impact on California consumers. The Initiative would change how many of the foods they eat are produced and would make that food more expensive. At the same time, however, the Initiative would provide relative little by way of consistent and useful information to consumers because of the loopholes and exceptions in its language and the uneven ways in which it would apply to the same food consumed in different settings. "
Oh the wonders and joys of rent seeking.
