Monday’s strike action will see barristers reject orders in Category A crown court cases such as murder and manslaughter.

They will also deny orders for new trials in any cases arising from hung juries or appeals.

There are warnings that more strike action could be coming unless there is an immediate increase in criminal legal aid fees.

The Law Society of Northern Ireland, the lawyers’ professional body, has warned that the criminal justice system will collapse unless urgent action is taken.

He added that lawyers would no longer be able to undertake criminal legal aid cases at current fee levels.

“The Law Society… is aware of the growing frustration of criminal defense lawyers with the failure to increase legal aid fees and delays in payments for work already completed,” a statement said.

The body called on Justice Minister Naomi Long to take action.
