Troubles cast long shadow over politics and justice
It was a year when the past once again cast a shadow over politics and the criminal justice system.
It began with Director of Public Prosecutions Barra McGrory under fire for decisions to charge three former soldiers with killings during the Troubles.
Unionist politicians and a number of military campaign groups accused him of conducting a witch hunt.
They claimed there was a disproportionate focus by the Public Prosecution Service (PPS) and police on investigating killings by the Army.
The director hit back in robust fashion.
He said those who accused him of treating former soldiers unfairly had insulted him and his office.
The police also produced figures that disproved the claims, revealing that investigations into killings by the Army accounted for about 30% of its legacy workload.
But that hasn't stopped the criticism, and there are now calls for a statute of limitations to prevent security force members being prosecuted for offences early in the Troubles.
In his final interview before retiring as director, Barra McGrory said a partial amnesty that only applied to the security forces could be open to legal challenge.
The year ended with the Police Ombudsman, Dr Michael Maguire, in the firing line.
Unionists called for his resignation after a judge was severely critical of his report on the Ulster Volunteer Force (UVF) murders of six Catholics at Loughinisland in June 1994.
Mr Justice McCloskey said the ombudsman's determination that there had been collusion between some police officers and the killers was "unsustainable in law".
The judge did not say collusion had not occurred, but that Dr Maguire did not have the legal powers to reach his conclusion.
The expectation is that the judge will quash the report when the court considers the matter again on January 12th.
That will almost certainly lead to appeals by the ombudsman and lawyers representing families of the victims.
Allegations of collusion were also at the heart of another high-profile case.
More than seven years after agreeing to become a so-called supergrass, the PPS announced that it will use evidence from former UVF commander Gary Haggarty in the trial of a man accused of murdering two Catholics in Belfast city centre in February 1994.
But it will not use him as a witness against two former police Special Branch officers he's accused of protecting and directing him.
Barra McGrory said his evidence alone was insufficient to secure a conviction.
Lawyers acting for a relative of one of Haggarty's victims have launched a legal challenge in an attempt to overturn that decision.
The government and all of the political parties have repeatedly said agreement on how to deal with the legacy of the Troubles is a priority, but such agreement appears as far away as ever.
Secretary of State James Brokenshire will finally launch his long-promised public consultation on how to deal with legacy issues early in the New Year.
It will include a question about a possible statute of limitations.
The consultation will not tell him anything he and the parties do not already know.
It is likely to simply reinforce how contentious the past remains, and how far apart the parties are.
The prospect of an agreement on how to move forward on the issue is remote.
