Two teams of investigators with experience in integrity were assembled to uncover corruption in the CFMEU union, but were swiftly disbanded.
The Albanese government's CFMEU reform chief, Mark Irving KC, abandoned the anti-corruption teams, leaving serious misconduct allegations untouched for months.
Irving was concerned that seeking more powers could risk reviving calls for the coalition's Australian Building and Construction Commission.
A top figure in the union was later sacked.
