Face coverings to be mandatory in Derry courthouse
But they will be mandatory within public spaces in courts or tribunal service buildings.
The guidance has been issued by the Department of Justice today.
It said their use in public spaces in their buildings was mandated as those were the areas people were most likely to meet people they would not meet ordinarily.
Courtrooms have already been set up for social distancing with capacity reduced.
Judges may ask those in the courtoom to remove facial coverings for identification purposes, if they are presenting evidence or if someone who relies on lip reading or facial expressions needs to see that person.
Courts are currently operating remotely but it is expected jury trials may restart in the forthcoming weeks after five months in lockdown.
