Nick Gordon No-Shows in Court, Loses in Bobbi Kristina Wrongful Death Suit

Bobbi Kristina's boyfriend has been found responsible for her death after failing to show up in court for the wrongful death lawsuit her family filed against him.

Nick Gordon repeatedly failed to meet court deadlines in the case, and his no-show Friday in an Atlanta court was the final straw. The judge entered a judgment against him, giving the estate the win by default ... according to Bobby Brown's attorney.

You'll recall Bobbi's estate filed the suit against Gordon, alleging he gave her the toxic mix of drugs, which the medical examiner said played the key role in her drowning death.

Bobby's attorney tells us the judge's ruling confirms what the family believed all along ... that "Nick Gordon was responsible for her death." Any damages Nick will be ordered to pay will be determined in a future hearing.

No criminal charges were ever filed against Gordon.
