The Ark Tribe court case will now reconvene on July 20-22 after the magistrate decided to adjourn the matter further.

The magistrate who needed to adjourn the case twice previously, said that the proceedings were vaildly brought and that the case should now continue as planned.

The defence, who originally argued the case should be thrown out on the grounds the prosecution lacked proper authority, will now continue their defence with Ark pleading not guilty.

Inside the Adelaide's Magistrate's court, the lawyers have now begun their defence of Ark Tribe, a normal construction worker accused of nothing more than failing to attend an interrogation by the Construction Star Chamber for the Australian Building and Construction Commission.

Previously lawyers argued that the ABCC had not correctly begun the prosecution - as the proper authority did not exist. As a result they said the charges should be thrown out.

Lawyers for the Commonwealth DPP contested the argument and the magistrate moved for an adjournment.

Both sides made written submissions on the matter, with the court case now continuing as a result of the magistrate's ruling.

If the arguments of Ark's lawyers were upheld, the case would have ended. Now, however, it will continue with both sides making arguments on substantive issues.

Workers, members of the broader community and unionists, were out in force outside and inside the court in support of Ark and against the ABCC.

CFMEU National Secretary Dave Noonan said today, "If Ark goes in; construction workers across the country would go out."
