Brenda Young, of Eastgate, Honley, was shocked when bailiffs turned up at her home to clamp her car last Friday evening.
The bailiffs carried out the clamping on the orders of Huddersfield Magistrates' Court for non-payment of a parking fine and court costs.
However, Mrs Young had already shown court staff documents proving she had lodged an appeal against the original £185 fine at Bradford Court and was waiting for a date for the hearing.
She said she had been assured that the bailiffs would be told not to proceed. The bailiffs initially clamped her husband Geoffrey's car - because Mrs Young's vehicle was still on a loan and was the property of the finance company.
The bailiffs then had a change of heart - and returned to unclamp Mr Young's car and clamp Mrs Young's vehicle.
Now, the clamp has come off for good.
Following phone calls to the court by her solicitor, Neil Murphy, the bailiffs returned on Monday to remove the clamps.
Mrs Young said court staff had blamed an administrative error for the clamping.
But she said: "We have human rights legislation which says everyone should be given a fair trial and be innocent until proven guilty.
"But that doesn't seem to be the case here.
"I feel really angry because everyone concerned had the right pieces of paper. It was almost as though no-one was talking to anyone else."
She added: "The mistake happened at Huddersfield Magistrates' Court and spread from there.
"If they made a mistake, they should own up to it and make sure it doesn't happen to anyone else."
Huddersfield court officials have refused to comment on or discuss the issue with anyone not involved.
