A kitchen company boss from Greater Manchester who was cleared of fraud claims the failed prosecution cost £4m, not the £2.1m stated in a report.
Vance Miller was taken to court by Oldham Council's trading standards, accused of conspiracy to commit fraud and making false representation.
The case was thrown out by a judge at Manchester Crown Court in January.
A report said the case cost £2.1m but Mr Miller said this was "nonsense". The council declined to comment.
Oldham Council's Trading Standards department's case focused on Mr Miller's kitchen business which went under a number of names, including Rock Solid Kitchens and Forever Kitchens.
Sue for compensation
The review, undertaken by lawyer Stewart Dobson, is due to be released to the pubic on Monday, and will go before Oldham Council's Audit Committee on 23 November.
Mr Miller said: "Before the trial began they gave me a bill of £2.17m.
"They served that on the defence.
"That did not include legal costs. That did not include defence costs. It did not include the £50,000 that has just been spent on this report."
The businessman from Ramsbottom said he and his solicitor had not seen the report.
He said he planned to sue for compensation.
In August, the council sacked its Trading Standards boss, Tony Allen, after receiving the first part of Mr Dobson's inquiry.
