Private Members' Bills: How do they work and what can they achieve?

07 May 2024 - by Matthew Jackson

The NI Assembly Speaker Edwin Poots MLA today announced that submissions for Private Members' Bills opens on 13th May until 5th July.

This presents an opportunity for organisations to engage with MLAs on areas they are campaigning on and also to support the legislative journey of a Bill.

What is a Private Members’ Bill?

A Private Members’ Bill is a legislative proposal which is brought before the Assembly by a Member of the House who is not a Minister. That means it is not necessarily Executive policy and has not been prepared by a specific Department.

They are an opportunity for backbench MLAs to initiate and drive legislation, and affect real change on a given issue.  

What happened in the last mandate?

Of the 20 bills introduced (between January 2020 and March 2022), 10 were passed by MLAs and became law. This was an increase from the seven Bills passed during the entirety of the 2011-16 mandate.

Changes brought about by these bills include modernisation of defamation law (Mike Nesbitt MLA), free period product provision in public buildings (Pat Catney), ensuring safe leave from work in cases of domestic abuse (Rachel Woods) and greater facilitation of integrated education (Kellie Armstrong MLA).

Importantly however, even if a bill fails to make it through the legislative process, it can still have an impact on shining a light on an issue and persuading the relevant Minister and department to act.

For example, although Clare Bailey’s Climate Change Bill was withdrawn at Further Consideration Stage, much of it was incorporated into the Department’s own Climate Change Bill which became law in March 2022. Somewhat differently, Colin McGrath MLA’s Education (Curriculum) (CPR and AED) Bill was adopted by the Education Minister following Second Stage, with the provisions enacted through secondary legislation.

And while John Blair MLA’s Hunting of Wild Mammals Bill also failed to become law, falling at Second Stage, it garnered over 16,000 consultation responses, received much media attention and will more than likely return again this mandate.

Is the process for a PMB any different than Executive Bills?

The Standing Orders which govern the Assembly make no distinction between Executive Bills introduced by Ministers and those brought by Members, and the technical procedure once introduced to the Assembly is identical.*

However Executive bills will have significantly more resource behind them, with departments supporting their development unlike those put forward as Private Members’ Bills; though this in itself is an opportunity for organisations to offer their expertise.

Nonetheless, Executive business will always take precedence over Private Members business in the Assembly Chamber, particularly during busy periods such as we saw during the COVID response, and towards the end of a mandate when a range of Bills are competing for airtime.

For this reason, it is advisable to submit your Bill early in the mandate to maximise its chances of becoming law.
