A federal judge has thrown out a Texas tax attorney’s lawsuit against his alma mater, Georgetown University Law Center, that claimed the school unlawfully banned him from  a job fair after concerns arose over discrepancies on his resume.

Judge Barbara Lynn of the U.S. District Court for the Northern District of Texas dismissed John Anthony Castro’s suit Tuesday on the grounds that the court lacked personal jurisdiction over the law school in Washington, D.C.  “Defendants’ only alleged contact with Texas is that Castro, a Texas resident, placed a phone call, on an unidentified date, to Georgetown University’s Career Services Office,” Lynn wrote in her opinion. “This single contact is not evidence that Defendants purposefully directed any activities to Texas.”
