L.A. County Superior Court Judge David Cunningham just told Justin's lawyer the star must make his case against Karen McNeil by personally testifying.
Justin's lawyer, legal pit bull Marty Singer, was furious, saying McNeil has violated the TRO 10 times already. And besides, Singer says, Justin is filming a movie and has a contract requiring him to be there.
The judge was unmoved, saying it's unfair to make a common working man appear in court but not a high-profile type who has a high-paying gig.
The judge told Singer he wants him to get in touch with Justin and have him on stand-by.
UPDATE 4:45 PM PT -- Court is back in session and no JT in sight. McNeil herself will take the stand and Justin's lawyers will submit a declaration on JT's behalf.
UPDATE 5:15 PM PT -- McNeil has been testifying for some time now. She says she won't continue to bother JT because she's had enough of arrogant, rich men. Child, haven't we all?
