Stormont MLAs have rejected a controversial Government plan to ban prosecutions for Troubles murders.

In a recalled sitting of the devolved legislature, members backed a non-binding motion denouncing the contentious proposals to introduce a statute of limitations on crimes committed during the Northern Ireland conflict.

The motion, tabled by SDLP deputy leader Nichola Mallon, passed by way of an oral vote, without any dissenting voices, at the end of a two-hour debate at Stormont.

Earlier, Ms Mallon told the chamber that a prosecution amnesty would not be acceptable in any other modern democracy in the world.

Opening the debate, she accused the Government of attempting to sweep victims’ pain under the carpet.

She said the proposals would let “perpetrators, state and paramilitary, walk free and instead condemn the victims and their families to a lifetime of pain and suffering through the denial of hope, truth and justice”.

Ms Mallon branded the proposals a “unilateral move” by the UK Government to deliver a “Tory party answer to a problem created by that same party and its backbench MPs”.

“Backbenchers who have created a bogus myth that an endless parade of veterans are being dragged through the courts here to answer for their past.

“When the fact is that is not true,” she said.

“Rather than debunk the myth and deal in facts, Boris Johnson and Brandon Lewis have decided to cruelly abandon victims and survivors as they play to the gallery.”

As the debate took place in Belfast, some victims of terrorism travelled to Downing Street in London to express opposition.

Other campaigners gathered outside Parliament Buildings at Stormont.

Northern Ireland Secretary Brandon Lewis announced last week that he intends to introduce legislation to create a proposed statute of limitations which would end all prosecutions for incidents up to April 1998 and would apply to military veterans as well as ex-paramilitaries.

The proposals, which Prime Minister Mr Johnson said would allow Northern Ireland to “draw a line under the Troubles”, would also end all legacy inquests and civil actions related to the conflict.

But the plan has been heavily criticised by all the main political parties in Northern Ireland as well as the Irish Government, and a range of victims’ and survivors’ groups.

Ms Mallon said the amnesty proposal had devastated and re-traumatised survivors and bereaved families.

“It hasn’t drawn a line.

“It has made the situation worse,” she said.

The Stormont minister added: “This British Government, in doing this, is telling families that their loved one’s life didn’t matter, that their lives, their families’ loss isn’t worthy enough to be properly investigated in a process with integrity.

“It is disgusting and, Mr Speaker, it would not be acceptable in any other modern democracy in the world – and it cannot, and must not, be deemed acceptable here.”

Ms Mallon urged all Stormont parties to unite in their opposition to the amnesty and work together to develop an agreed way forward on dealing with the past.

She said a failure to do so in recent years had created the opportunity for the UK Government to step in and propose the statute of limitations.

Ms Mallon urged parties to recommit to the stalled 2014 Stormont House Agreement proposals, which included an independent investigations unit.

Addressing the chamber during the debate, DUP MLA Mervyn Storey said victims “cannot and should not be ignored in this way”.

“The Secretary of State seems to have chosen a path which finds equivalence between the soldier and police officer, and those who planted the bomb or pulled the trigger,” he said.

“This is morally reprehensible.”

The DUP MLA also criticised Sinn Fein for accusing the UK Government of “covering up the truth”, highlighting that the IRA was responsible for the vast majority of Troubles crimes.

Sinn Fein deputy First Minister Michelle O’Neill said the proposals would deny bereaved families their rights.

“The British political system cannot handle the truth,” she told MLAs.

“The British Government fears the bravery, the courage and resilience of the families.”

Ms O’Neill added: “The legacy proposals to deny families any legal redress to justice is a statement of moral bankruptcy.

“The British Government approach is cynical because they’re seeking to insulate their forces from legal challenges by shutting down the established legal options that are open to families.

“Today we must send a very clear message that any political attempts to interfere in live and pending legal proceedings will be resisted by everyone across this House.”

Ulster Unionist Party leader Doug Beattie voiced opposition to any move toward an amnesty.

“We have been quite clear that the soldier, the policeman, a terrorist, a member of the public or a politician, if you break the law, then you should face the law,” he said.

“And everybody deserves the opportunity to get justice.

“It doesn’t mean they always will, but we cannot take away that hope.”

However, Mr Beattie also criticised the 2014 Stormont House legacy proposals, highlighting that they did not envisage a reinvestigation of crimes, other than murders.

Alliance Party leader Naomi Long said the legacy proposals were “neither victim-centred or victim-focused”.

“To the contrary, both the proposals and how they have spun out in the media before any victims groups were even aware they were coming have re-traumatised many families, compounded the hurt and sense of abandonment which they feel and has sought to rob them of any remaining hope they had that they might ever see justice for their loved ones,” she said.

Ms Long also queried “what kind of message” the legacy proposals send to those still engaged in terrorism and to their victims.

“The Secretary of State’s proposals are profoundly flawed and not grounded on the needs of victims’ families for truth and justice,” she said.
