The UK government is to progress an organ donation law championed by a six-year-old Belfast boy who needs a heart transplant.
The legislation has been held up due to the collapse of Stormont.
The family of Dáithí Mac Gabhann had been pushing hard to get it through.
It would effectively make all adults in Northern Ireland organ donors unless they opted out.
The issue developed into a row in recent weeks with Northern Secretary Chris Heaton Harris saying the Assembly was the quickest way to pass it.
Last week, a Stormont recall called with the intent of passing the necessary secondary legislation failed when the DUP refused to support the election of a speaker.
The DUP, which is refusing to renter power-sharing in opposition to the Northern Ireland Protocol maintained it could be done at Westminster.

It said an upcoming bill there to extend the deadline for an assembly election to 2024 could be easily and quickly amended to include it.
The Northern Secretary had argued the scope of the bill was too narrow and that such a move would be difficult.
But now it is going ahead.
Mr Heaton Harris spoke to the Mac Gabhann family last night and has now confirmed an amendment will be tabled in the Commons.
"I have been incredibly moved by Dáithí's story and his family's dedication. I know that the party leaders in Northern Ireland feel the same.
"In recognition of just how important this issue is, I have decided to bring forward an amendment to the Executive Formation Bill which will allow for the overdue legislation to be made by the NI Department of Health and see this change to the law become a reality.
"I would like to reiterate that, if the amendment is selected, the UK Government’s intervention here is exceptional. Decisions such as these should be being taken by locally-elected decision-makers.
"I urge the parties to take the necessary steps to tackle all the other vitally important measures, just like this one, that they could deliver in Northern Ireland by simply agreeing to restore the institutions."
