Complain about a judge, magistrate, tribunal member or coroner

You can complain if you’re unhappy with a judge, magistrate, tribunal member or coroner’s:

  • behaviour
  • language
  • conduct

There’s a different complaints process in Scotland.

You must make your complaint within 3 months.

You cannot use the complaints process to challenge a decision or sentence. You should get legal advice about how to appeal.

How to complain

There’s a different process for tribunals, magistrates’ courts and judges sitting in other courts.


Contact the Tribunal President for the tribunal you went to, for example the employment tribunal or immigration tribunal.

Magistrates’ court

Contact the advisory committee for the area your court is in. You can ask a member of staff at court if you’re not sure which advisory committee to contact.

Judges sitting in other courts

This includes:

  • Crown Court judges
  • coroners
  • district judges

You can complain online on the Judicial Conduct Investigations Office (JCIO) website.
