The court pleading submitted by the Petitioner are available here. And the papers for the Respondent - Warren Slocum, are here. The California Secretary of State is being represented by the Attorney General and their pleading is viewable here.
Note: On Verafirma's (developers of the electronic signature application) Facebook site the firm states, "California Secretary of State writes amicus brief opposing Verafirma -- reveals deep and profound lack of understanding of even simplest technology." Pretty strong words!
