The prosecutor in the case of a Birmingham pair who made more than £1million in bogus claims for cab fares said Lisa Burrows exploited her workplace's policy of providing funds for taxi travel.
Burrows was employed as the area finance manager for the Crown Prosecution Service in the West Midlands.
The 42 year old and Tahir Mahmood were sentenced to six years in prison.
Burrows identified that the CPS spent considerable sums on the provision of taxis.
She then decided, along with Mr Mahmood, to exploit that by making false claims for non-existent journeys.
Mahmood played a full and significant role in the conspiracy in the initial planning of the fraud and by ensuring that they could get their hands on the money in cash form by setting up bank accounts in false names.
He withdrew nearly £1 million in cash over five years, most of which is still unaccounted for.
