Three Magistrates courts in the Thames Valley are set to close.
The Ministry of Justice has announced courts in Aylesbury, Bicester and Newbury will be shut down.
It could mean longer journeys for victims and witnesses who would have to travel to Reading instead.
The Ministry of Justice says savings have to be made, and much of the work of magistrates courts can now be done online.
But the Thames Valley Police Commissioner Anthony Stansfeld said he was disappointed by the decision.
