Demitri was in court Wednesday when the judge dissolved the temporary restraining order his third wife, Christeline Petersen, got against him when she made allegations of domestic violence. The judge found Christeline did not meet her burden of proof.

Christeline testified what we had first reported ... claiming Dimitri slammed her head into the headboard and choked her during sex after she told him to stop.

Dimitri countered by showing text messages he claims Christeline sent him saying she liked the choking. In the end, the judge said she could not ascertain which party was telling the truth ... so she tossed the case. As for Christeline's separate allegations against Ashley -- one of Dimitri's other wives -- the judge tossed that case, as well.

As we first reported ... Christeline, who came to the U.S. from South Africa to be courted as a third wife on the TLC reality show, claimed in legal docs she suffered bruises, scratches and redness around her neck.
