Barristers in the Criminal Bar Association will support a work-to-rule by solicitors against new cuts to Legal Aid.
Barristers voted by 55 percent to join the action.
This means that from 27 July barristers will refuse to cover work for colleagues who are the instructed advocate in Legal Aid cases.
Such “returns” account for a large amount of the day-to-day work in criminal courts.
Barristers, solicitors and others working in the legal system are set to join a protest on Wednesday of this week.
It will be outside Westminster Magistrates Court in central London from 9am.
