The building watchdog has launched a new proceeding against union heavyweight Joe McDonald for his involvement in unlawful industrial action at the City Square project last year.
The Australian Building and Construction Commission said it had filed an application in the Federal Court in Perth yesterday over what it claims was an unlawful strike at the city project in July.
The ABCC alleges that Mr McDonald, who is the CFMEU assistant secretary in WA, visited the site on July 15 and spoke with employees, who then left the site and failed to return for the rest of the day.
Brookfield Multiplex, which is the head contractor for the City Square project, is currently seeking a Federal Court order to restrain Mr McDonald from being involved in industrial action at the site.
Brookfield's application is set to be heard early next month, and the ABCC today said it is seeking to consolidate its proceeding with the company's.
The maximum penalties for the unlawful industrial action are $22,000 for an individual and $110,000 for an organisation.
