A council will have to foot a Pfund750,000 legal bill for a court case in which a disgraced social worker lied, leading to her criminal past being exposed.
Bath and North East Somerset Council employed Lynda Barnes, who had a conviction for conspiring to murder her ex-husband.
Mrs Barnes, 55, from Nailsea, North Somerset, was employed by Banes in 2005 despite the fact that she had been sacked by its predecessor, Avon County Council, ten years earlier following her conviction.
She was given a two-year suspended jail sentence at Bristol Crown Court on March 24 1995 after pleading guilty to conspiracy to murder her ex-husband after asking someone to hire a hit man for Pfund10,000.
Mrs Barnes worked as a social work team manager for Banes for more than three years on child protection cases.
The matter came to light during a child protection case being heard in a family court where she is alleged to have lied on oath and asked another social worker to lie to the court.
The judge in the case, Judge Paul Barclay, was appalled and carried out his own inquiries into Mrs Barnes' past.
He published his ruling in the case last week after Mrs Barnes failed in a Court of Appeal application to prevent her being identified.
Judge Barclay has now ordered the council chiefs who hired her to pay half the legal aid costs of the families involved in the case.
They are expected to exceed Pfund500,000, which will be on top of the council's own legal fees, which could be around Pfund250,000.
Today the council reassured taxpayers that services would not be directly affected by the case.
A spokesman said they had planned for the possibility of a hefty legal bill in their budget and would take the case from their 'risk reserves' pot.
