The shadow minister for innovation, industry, science and research, Sophie Mirabella, wrote to the government requesting it establish an inquiry. Mirabella said she is aware of as many as 100 cases of alleged workplace harassment. On 20 July 2012 Comcare issued CSIRO with an Improvement Notice with regard to handling and management of workplace misconduct/code of conduct type investigations and allegations. On 24 June 2013 Mirabella advised the Australian House of Representatives that in relation to the worker's compensation claim for psychological injuries of ex-CSIRO employee, Martin Williams, which was vigorously defended by Comcare on the advice of the CSIRO, that CSIRO officers had provided false testimony on no less than 128 occasions under oath when the matter went before the Administrative Appeals Tribunal. Mirabella stated, "even in establishing the framework for this inquiry it is obvious there's an inappropriate 'hands on' approach by CSIRO."
