Do you have a reliable source for that? The source in your link has no date, no author, and no source for the information. The snopes article that Bo-4 linked says that Harrison Bounel never had the SSN that Barak Obama has.
When I did a Google search on Judge Hollander, the only sources that showed up were GOP/Conservative mouthpieces and not reliable news sources.
GOP Daily Dose said Judge Hollander gave Attorney Orly Taitz additional time to file an amended complaint. Taitz believes that this ensures the Judge will act in favor of the complaint but that is only an opinion. It never says that the Judge ordered an investigation.
Do you have something better? Until then, this is just a rumor from strongly biased sources.
