If, as Michaelia Cash has consistently maintained since last October, she had nothing to do with the guest appearance by the media at controversial Australian Federal Police raids on Australian Workers Union offices in Melbourne and Sydney, surely the best way to put the matter to bed would be to front up to the Federal Court as requested and say so.
The embattled jobs minister was placed in an extremely embarrassing position when the media was tipped off that the raids, being carried out as part of a Registered Organisations Commission investigation into the AWU, were about to occur.
Queried about the matter at the time of the October 24, 2017, raids which made that evening's national television news, Ms Cash vehemently and indignantly denied either she, or anybody employed by her, had anything to do with what was obviously a very serious breach of operational security.
That all changed within 24 hours when the minister conceded the media tip-off had come from her office and had been made by a then staffer, David De Garis.
Mr De Garis accepted responsibility. He then fell on his sword, leaving the way open for Ms Cash to ignore calls for her to resign in accordance with the long established Westminster principle of Ministerial accountability.
Both Ms Cash and Mr De Garis have now been subpoenaed to give evidence in Melbourne in August at a Federal Court bid by the AWU to have the ROC investigation terminated.
The obvious question, and one people have now been asking for the better part of 10 months, is just how such an extreme and provocative action, which was always going to become public by its very nature, could be taken without the Minister being aware of it.
Ms Cash, on the one hand, needs to explain how she came to be operating such loose ship. Mr De Garis, on the other hand, needs to explain how and why he felt comfortable acting unilaterally to this extent.
The AWU, meanwhile, maintains the investigation, into donations by the union to GetUp!, is a political witch hunt targeting, amongst others, the Opposition Leader, Bill Shorten.
It, along with many other individuals and organisations on the left, including GetUp!, regards the ROC - which operates as part of the Fair Work Commission - as a politically partisan agency established with the primary purpose of going after the Coalition's adversaries.
Speaking at the time of the raids, the Opposition workplace relations spokesman, Brendan O'Connor, accused the Prime Minister of treating the AFP as "a political plaything".
"The government is using the power of the state and using taxpayer dollars to attack its political opponents," he said. "There were cameras waiting outside the premises of the AWU before the police arrived... clearly there's (been) collusion with this agency (the ROC) and the government with the media to ensure that this matter is elevated publicly".
That allegation, if true, needs to be investigated thoroughly and comprehensively.
This can only occur if Ms Cash stops hiding behind the lawyers she has retained to challenge the Federal Court subpoena and answer the pertinent questions.
