The wife of whistleblower Richard Boyle has implored Prime Minister Anthony Albanese and Attorney General Mark Dreyfus to put an end to her husband's prosecution. 

The couple's lives have been shattered as a result of the charges filed against Boyle after he exposed the Australian Taxation Office's ruthless pursuit of tax debts from small businesses, actions he deemed destructive and inhumane in their quest to meet revenue targets.

Boyle, who initially voiced his concerns internally before turning to an independent watchdog and the media in 2018, is facing 24 charges relating to his pre-whistleblowing activities. 

These include alleged unauthorised photography of taxpayer information and secret recordings of conversations with colleagues. 

Earlier this year, his attempt to use Australia's whistleblower protections to halt his impending trial proved futile, leaving him facing potential imprisonment.

Currently, Boyle is making an appeal to the SA Supreme Court, arguing that the state's district court erred in ruling that the Public Interest Disclosure Act could not safeguard him for acts conducted in preparation for whistleblowing. 

This case carries significant weight in assessing the strength of Australia's whistleblower protection laws.

Mr Boyle's wife Louise Beaston, deeply affected by their ordeal since federal police and tax officers raided their home in 2018 and her husband was charged in 2019, has sent impassioned letters to Albanese and Dreyfus, urging them to exercise their rarely use powers to terminate the prosecution. 

She pointed out the devastating toll the ongoing legal battle has taken on their mental and physical health, noting that Boyle had only ever sought to reveal the truth.

Despite growing calls for intervention, Labor has thus far resisted intervening in Boyle's case. 

Dreyfus, for his part, has stressed the importance of integrity and the rule of law in Australia's criminal justice system, reserving his powers to intervene for exceptional circumstances.

One of the beneficiaries of Boyle's whistleblower actions, Dirk Fielding, expressed his remorse for the predicament Boyle now finds himself in. 

Boyle came to Fielding's aid when the ATO used aggressive debt collection tactics that imperilled his publishing business. 

Fielding credited Boyle with saving his business from ruin and admitted to feeling partially responsible for Boyle's legal troubles, given that his tax information was discovered in Boyle's home.

“I honestly feel that I am to blame,” he said.

“I feel absolutely terrible for Richard who's put his life on the line to help me … and he's been persecuted to such an extent. It's just insanity.”

As Boyle's criminal trial approaches, his legal team is pursuing immunity from prosecution by challenging whistleblower protection laws. 

This legal battle's outcome holds significant implications for the protection of all current and future whistleblowers in Australia, as observed by Kieran Pender of the Human Rights Law Centre.

The plea for Attorney General Mark Dreyfus to pardon Boyle under section 71B of the Judiciary Act, a power he exercised last year to discontinue the prosecution of lawyer Bernard Collaery, has also gained traction. 

Fielding and Beaston both echoed the sentiment that Boyle's actions were righteous and should not result in incarceration.
