Hello Ros my name is ***** ***** I will help you with this.
The fact this person is a JP does not stop them giving a reference.
As long as they are not conflicted in the case then there is no issue.
They are able to give a reference if they wish. It may just be a polite way of saying that they do not want to.
But there is no issue in a JP giving a reference, they do not even need to say they are a JPCan I clarify anything for you about this today please?
