Two construction union officials have been found liable of breaching workplace laws after refusing to show their right of entry permits when entering a work site and for swearing at the person who asked to see them.

When the site manager for the Bendigo Theatre Project, located on the grounds of the Bendigo Senior College, asked CFMEU officials Nigel Davies and Alex Tadic to show him their right of entry permits in July 2014, they refused.

The Federal Court of Australia heard that the site manager, Simon Ireland, told the pair they were welcome on the site if they showed him their permits, but if they did not, they would have to leave.

The court heard that Mr Tadic said words to the effect of, "I am not dealing with a f-----g pen pusher f--k off" and that he called Mr Ireland "a f-----g disgrace".
