Amber Heard Cried, Yelled, Screamed ... You're Not Taking My Depo!!!

Amber Heard refused to go under oath Saturday for her deposition, crying, yelling and screaming in defiance ... so claim Johnny Depp's lawyers, who want the judge to call BS on her and dismiss the domestic violence case.

TMZ broke the story, Amber showed up around 11:50 AM Saturday for a 10 AM deposition. She was there until around 9 PM but never even walked in the deposition room, where lawyers, a court reporter and videographer were waiting.

According to new legal docs filed by Johnny's lawyer, Laura Wasser, Amber repeatedly refused to submit to questioning. According to the docs, at 2 PM Wasser and company wanted Amber to leave the adjoining office where she had been waiting and enter the conference room so the depo could begin.

According to the docs, Amber refused to enter. At 5:30 PM, Wasser again requested Amber to enter the depo room and again she refused. She never went in the room, instead, according to Wasser, she began crying and carrying on in the adjoining office.

Wasser says Amber also refused to turn over documents she had requested.
