Two officials of the Construction, Forestry, Mining and Energy Union have been charged following referrals from the trade unions royal commission.
Michael Greenfield, an organiser with the NSW construction branch of the CFMEU, will face a Sydney court in November charged with intimidation of Commonwealth public officials, the Commonwealth Director of Public Prosecutions (CDPP) has confirmed.
The public officials in question are Fair Work Building Industry (FWBI) inspectors.
Luke Collier, an officer with the CFMEU, has also been charged with intimidation of FWBI inspectors and with assault under NSW laws, the CDPP said.
Mr Collier's matter has been listed for mention in a Sydney court in February.

The charges against the men follow evidence heard at the royal commission last year about a confrontation between FBWI inspectors and union officials at the Barangaroo building site in Sydney in July, 2014.
The penalty for obstruction of a Commonwealth official is two years' jail.
Earlier this month, a blackmail charge against another CFMEU official, former rugby league player John Lomax, was dropped when prosecutors did not present any evidence to the court.
Mr Lomax had been charged by police attached to the trade unions royal commission.
He said he was considering legal action after the charges were dropped.
Commissioner Dyson Heydon referred Mr Greenfield, Mr Collier and a number of other CFMEU officials to the Commonwealth DPP and other agencies for consideration of charges in his December, 2014, interim report.
