Northern Ireland Secretary Karen Bradley's ongoing failure to compensate victims of historical abuse in the absence of a Stormont executive is not unlawful, a High Court judge in Belfast has ruled.

An abuse survivor failed in his bid to compel Ms Bradley to implement stalled redress mechanisms for victims and call an Assembly election.

But Judge Bernard McCloskey opened the door for a further potential challenge if Ms Bradley does not act on draft legislation on the compensation scheme that has been developed by Stormont civil servants.

He said the current political vacuum was unsatisfactory but it was not unconstitutional.

"The plight of victims and survivors of historical institutional abuse in Northern Ireland illustrates graphically just how damaging this is for certain sections of society," he said.

The case was taken by an unnamed male victim, who is now in his 70s, known to the court as JR80.

He was challenging the lack of action on recommendations by a state inquiry into historical institutional abuse in the North.

The proposals put forward by the HIA inquiry, chaired by retired judge Anthony Hart, are mired in uncertainty due to the Stormont impasse.

They were published just as the DUP/Sinn Féin-led executive was imploding in January 2017, so no elected local ministers have been able to take action.

A public consultation on the proposed shape of the compensation scheme closed last month, but the plans cannot be implemented without intervention by the UK government.

The HIA inquiry studied allegations of abuse in 22 homes and other residential institutions between 1922 and 1995.

There were 76 homes that operated during that time and abuse victims from all of them would be eligible to apply for compensation.

The facilities were run by the state, local authorities, the Catholic Church, the Church of Ireland and children's charity Barnardos.

The inquiry recommended compensation payouts ranging from £7,500 to £100,000 for victims.

Members of the Northern Ireland Affairs Committee at Westminster have written to Ms Bradley urging her to intervene and legislate for compensation.
