The Conservative government in Westminster is using its parliamentary majority to impose the Legacy Bill on Northern Ireland.

Virtually no-one here wants it; not people who lost loved ones, not the political parties.

Many families are still waiting for answers.

There are 900 Troubles cases which remain unsolved. They relate to 1,200 murders, a third of all the killings.

So why is the bill being pushed through?

Legacy was not addressed in the 1998 Good Friday Agreement.

It was too soon, too complex to crack and was put to one side.

In the intervening 25 years there have been numerous attempts to sort it out.

In 2014, there was agreement on a legacy plan which left open the option of court proceedings, but it has never been implemented, amid intermittent Stormont collapses and what the SDLP claim was UK government foot-dragging.

The British government says it is now bringing the whole issue to a head with a proposal that will produce the most information in the shortest timeframe.

The plan is to shut down access to the courts and push future cases into a commission which will produce reports for families who contact it.

Cynics say a big driver is to protect former British Army veterans and the state from embarrassing revelations during inquests and civil actions.

The single biggest issue is an amnesty for killers who provide information to the commission.

But few people believe there is any motivation for someone responsible for a murder decades ago to come forward now.

Another factor to consider is that the legacy plan has a provisional five year lifetime.

So killers still alive only have to sit it out for a few more years and the very slim prospect of arrest and prosecution will most likely disappear forever.
