Aylesbury Magistrates Court faces the looming possibility of closing as early as October, according to a magistrate.
A consultation period on whether the court should be closed and cases held at High Wycombe and Milton Keynes is believed to begin next month.
Chloe Lambert, an Aylesbury magistrate since 1990, said she would resign from her position if the court does close.
She said: “An email went around saying that Bucks was over courted and there are too many courts for business we are doing which I find faintly surprising.
“I can’t believe our business is as such that we don’t need to run courts in Aylesbury but I think it is a foregone conclusion.
“I’m extremely concerned especially as Aylesbury is the county town. It should have the magistrates court.
“Magistrates are supposed to be all about local justice. I’m not as familiar with the situation in Wycombe or Milton Keynes as Aylesbury. I have lived here for over 40 years and I know what’s going on here.
“If it means further delays of getting cases to court then it totally defeats everything we were trained to do in speeding up justice.”
The magistrate said she feared many of her colleagues would also resign and that county council should be concerned as it will have an economic impact.
A HM Courts and Tribunals Service spokesperson said: “HM Courts and Tribunals Service continues to keep the use of its estate under review to ensure it meets operational requirements.
“Any new proposals to close courts beyond those already announced will be subject to consultation. No decisions have been made in regards to any future closures.”
