"can use multiple attempts to pursue loopholes in the judicial system"

Your ignorance on full display yet again.

First trial discharged, jury unable to reach a verdict.

Second trial, found guilty.

Appealed to court of appeal, conviction upheld.

Appealed to High Court, submissions heard over 2 days, leave to appeal granted, convictions quashed via unanimous verdict of all 7 high court justices.

Conviction, appeal, high court.

All normal, all available to anyone with credible grounds of appeal.

Read Austlii website, and get informed better. Because at the moment you are posting complete BS.
