Prop. 37, the Proposition to label GMO foods did not pass in California.  This was understanably a let down for Whole Foods, and others who want to know exactly what goes in their food. However, asking the government to regulate is not a pure Libertarian request.  Instead, Libertarians advocate that people should demand the results with their business, not by government force.

A not-so-typical GMO Case Study about Monsanto and the 'people' behind Monsanto.
Now we are left to wonder, who are these people? Are they Libertarians? If they are, can we consider them Fake Libertarians?
