Andrew Montgomery chased Dean Montgomery along a street while his victim clutched the severed lobe. He then launched a vicious assault on his relative. Dean was left needing extensive reconstructive surgery to create a new ear as the detached part could not be saved.
The assault came after a family dispute over a grave plot, with various exchanges between family members over the two weeks before the attack.
Montgomery approached Dean in Dundee on July 30 last year, when a fight broke out. Both men fell to the ground, with Dean aware the accused was biting his ear.
Fiscal depute Trina Sinclair said: "The accused had a grip of his ear in his teeth and the complainer was afraid to pull away in case his ear became detached. He was then aware of part of his ear falling to the ground. He picked it up at this time and had it in his hand."
Miss Sinclair said: "The accused caught up with the complainer and knocked him to the ground and repeatedly punched him on the head and body." Montgomery, 34, of Dundee, pleaded guilty to assaulting Dean Montgomeryto his severe injury and permanent disfigurement.
Jack Brown, defending, said there had been a long-standing family dispute and Dean "was not the shrinking violet".
