Criminal behaviour claims extend trade union investigation

THE Federal Government has extended the Royal Commission into Trade Union Governance and Corruption to give it more time to probe claims of criminal behaviour at the request of the commission's head.

The final report is now due before December 31 next year.

Attorney-General Senator George Brandis said on Tuesday he had received a letter from Commissioner Dyson Hayden last week who said criminal conduct had been identified during the hearings.

In the letter Mr Hayden said "the inquiry thus far has revealed evidence of criminal conduct, which includes widespread instances of physical and verbal violence, cartel conduct, secondary boycotts, contempt of court and other institutional orders and the encouragement of others to commit these contempts."

An interim report will be delivered in December this year.
