FORMER union boss Dave Hanna could face criminal charges over claims he corruptly received $150,000 in illegal kick-backs to spruce up his home from the developers of Orion Springfield Central.
The Royal Commission into Trade Union Governance and Corruption made the recommendation in handing down its damning report this week.
Former Orion project manager Mathew McAllum and Mirvac employee Adam Moore could also face a similar fate.
All three have been referred to the Director of Public Prosecutions who will decide whether criminal charges should be laid against them.
Mr Hanna allegedly received the free materials and services in 2013 from Mirvac - who were constructing stage two of the shopping centre at the time.
The material and services allegedly went towards building Mr Hanna's palatial home at Cornubia on the Logan River, south of Brisbane.
The Royal Commission previously heard Mirvac hid the cost of the invoices in the Orion project which was coming in under budget.
Invoices included electrical work, tiling, plumbing, internal linings, plasterboard, carpentry and fixtures.
But Mr Hanna covered the cost of the windows because Mirvac did not have a window contractor on the Orion project.
Commissioner Dyson Heydon, in handing down his long-awaited findings, was scathing in assessment of trade unions across the nation.
He said illegal activity had taken place in a wide range of industries, unions and were not isolated incidents.
"It is clear that in many parts of the world constituted by trade union officials, there is room for louts, thugs, bullies, thieves, perjurers, those who threaten violence, errant fiduciaries and organisers of boycotts," he said.
"The misconduct exhibits great variety. It is widespread. It is deep-seated."
Commissioner Heydon's final report made 79 recommendations and referred a host of people across the nation to authorities for possible charges.
Mr Hanna has denied any wrongdoing and told the ABC he would defend any charges if they were laid.
"I will vigorously defend myself should there be any further developments after consideration by other bodies has occurred," he said.
Mr Hanna was the Builders Labourers Federation secretary before he became president of the CFMEU after the two unions merged.
