OTTAWA — A little-known, never-used government tribunal will spend as much as $8.1 million of taxpayers' money by the end of 2012-13, federal documents show.

The Public Servants Disclosure Protection Tribunal was set up in 2007 to protect public servants from retaliation after reporting immoral or illegal activities in government. Since then, it hasn't heard a single case.

The fact that the tribunal hasn't been used comes to light following the sudden departure on Oct. 18 of Christiane Ouimet, the first federal public sector integrity commissioner, while her office was being investigated by Auditor General Sheila Fraser.

The tribunal would take cases referred by the Ouimet's office. In three years, the commissioner didn't find any wrongdoing in any of the 170 complaints her office received.

Fifty-eight whistleblowers complained to the commissioner's office since 2007-2008, saying they were mistreated or violated after filing a report. The commissioner launched only four investigations as a consequence of those complaints, and only two have been completed.

Because neither had findings of reprisal, the tribunal has never been referred a case.

"It's clearly a waste of money," said David Hutton, executive director with the Federal Accountability Initiative for Reform, a registered charity advocating for whistleblower protection. "This whole expensive system has achieved absolutely nothing. In fact, it has made things worse."

Hutton said the tribunal gives whistleblowers an "illusion of protection" when the reality is civil servants are left without recourse after filing a complaint to the integrity commissioner about irresponsible, immoral or illegal government activities.

The tribunal spent $836,000 in 2008-09, according to its performance report from that year, and has tabled spending estimates of $1.83 million for each successive year until 2012-13.

Lisanne Lacroix, the registrar and deputy head of the tribunal's office, said she is surprised they haven't received a single case in three years. But, as she pointed out, the lack of work has meant less money actually spent.

"I have $1.828 million in my budget," she said. "But since we haven't had any cases, I haven't spent it."

Money not used is returned to the government each year.

While waiting for a case, the office has established rules and guidelines, trained staff and become familiar with legislation, Lacroix said.

She said the office currently employs four full-time and two part-time employees.

But if and when the tribunal eventually hears a case, there is virtually no chance the public servant will win, Hutton argues.

An equivalent "kangaroo court" in the United States heard 2,000 complaints, and only four cases prevailed, Hutton said. "It's virtually impossible for an employee to prove that an employer took reprisal against them. It's very hard to look at this system and come to any conclusion other than this is for show."

Prime Minister Stephen Harper created an independent Public Sector Integrity Commissioner to protect whistleblowers in 2007, with the intention of making civil servants feel protected when calling government on a misdoing.

But some opposition MPs say it's clear the legislation isn't working.

"I think you can safely say the Conservatives broken promises are expensive," NDP MP Pat Martin said. "It's a smoke-and-mirror illusion of whistleblower protection, when really, the legislation is inadequate to really protect them in any case."
