The High Court has ruled that New South Wales laws targeting outlaw motorcycle gangs are invalid.

The laws were introduced by Nathan Rees immediately after a fatal brawl between the Comancheros and Hell's Angels at Sydney Airport in March 2009.

The Criminal Organisation Control Bill had the power to declare bikie clubs illegal organisations.

Under the law, Bikie members could be jailed for associating with each other, have their assets frozen and be restricted from certain employment opportunities.

Lawyer Wayne Baffsky, who fought this decision in the High Court for his Hell’s Angel’s client Derek Wainohu said that this was a “completely unnecessary piece of legislation” and “unconstitutional”.
