The Recording Industry Association says it has won its first music piracy case before the Copyright Tribunal under a controversial law, with the offender being fined $616.
RIANZ - an organisation which represents record labels and musicians - said today a claim it brought to the tribunal was upheld, in a decision that is the first of its kind under 2011 changes to copyright laws.

The amendment to the law allows rights holders - such as movie studios or music companies - to issue warning notices to users believed to be illegally downloading copyrighted content.

After a third notice, rights holders can bring a case before the tribunal, which can fine an offender up to $15,000.

In a statement, RIANZ said today it was pleased the tribunal had "upheld laws protecting the rights of artists" and via email a spokesperson said the exact penalty dished out to the offender was $616.57.

"However, as you'll note, it's not about the money for RIANZ, it's about making a point that illegal file sharing is not okay and that if you do it and are caught you can expect to face a fine," a spokesperson said.

RIANZ said there are 11 further cases still live before the Tribunal.

The recording industry body would not release the tribunal's full decision and the Herald has made a request to the Ministry of Justice for this.
