A PPS spokesperson told BBC News NI: “In April 2024, the PPS took decisions not to prosecute 16 individuals [including 15 soldiers] in relation to allegations of false evidence relating to the Bloody Sunday Inquiry.
“A request to review these decisions was received by the PPS.”
The spokesperson described the process as ongoing, adding the outcome will be issued “in due course”.
They said the review was being carried out by a senior PPS lawyer who was not involved in taking the original decisions.
A solicitor representing some of the Bloody Sunday families, Ciarán Shiels, said he did not see any reason why the PPS could not make a decision “by the end of the month”.
Referring to Judge Patrick Lynch’s Soldier F verdict, in which he said some soldiers had perjured themselves, Mr Shiels added: “A judge said that a witness was serially untruthful to matters central to the enquiries into Bloody Sunday.
“This is something the Public Prosecution Service needs to take fully onboard.”
