"An either way offence, also known as an indictable offence, may be heard either in the Magistrate’s Court or in the Crown Court. The defendant will initially appear in the Magistrate’s Court. Both the defendant, and the Magistrate have the option to request that the case is transferred to the Crown Court."

It seems a matter of competence to hear the case. As we don't have a similar instance in Brazil, maybe you'd have to add an explanation note.
