Some of their decisions in biology are equally suspicious. For example, should genes, proteins, or DNA be patentable? That one has gone to the Supreme Court on occasion. But patenting human genetics can lead to crazy scenarios like "suddenly the entire human population in the United States is violating Monsanto's patent", which is patently absurd. Of course, I am purposefully exaggerating and twisting some of the arguments, but you can see how the courts can get biology just as wrong as any other technology.
On a related and amusing note: In March 2000, President Clinton announced that the genome sequence could not be patented, and should be made freely available to all researchers. The statement sent Celera's stock plummeting and dragged down the biotechnology-heavy Nasdaq. The biotechnology sector lost about $50 billion in market capitalization in two days. see http://en.wikipedia.org/wiki/Human_Genome_Project
