The drummer was sentenced to eight months of home detention after pleading guilty to charges of threatening to kill and drug possession.

Rudd's lawyer, Craig Tuck, argued the drummer should have been discharged without conviction, insisting his sentence was "excessive".

In a judgment released early on Tuesday (06Oct15) in New Zealand, Justice Raynor Asher ruled the conviction matched the crime and stated, "Even with the convictions, Mr. Rudd may practice as a musician in session work and in concerts in New Zealand and in other countries."

Rudd recently told Rolling Stone the charge of "threatening to kill" an associate was a "complete crock of s**t".

The drummer, who was kicked out of AC DC as he fought the allegations against him, is working with a top psychiatrist as he battles "my imbalances and personal issues".

Rudd has also been banned from having alcohol in his house and faces a court appearance next month (Nov15) after a guest arrived at his home with beer.
