In a judgment published last week, the court said it could find no evidence that Magill, who at the time worked for Deloitte & Touche, had acted unfairly.
Magill spent over 12 years engaged in proceedings against former council leader Dame Shirley Porter. The £3m investigation centred on claims that the council had engaged illegally in a housing sales policy designed to keep the London borough under Conservative control.
Magill imposed a £31.7m surcharge on six individuals involved in formulating the policy in 1996. A series of appeals have seen the claims against Dame Shirley and David Weeks, her successor as council leader, upheld, though the surcharge was reduced to £26.4m.
The average cost of fraud increased 35.4% to £3.9m in 2016, compared to 2015 data
