The first step in changing party policy is to submit a motion to conference. Practically any party unit can do that, including Branches, and Electoral Councils.
Once you have passed the motion at a branch or SEC or FEC, the secretary has to submit it. If you’re quick, there’s still a few hours left to get it onto the agenda for the 2016 conference:
Has to be done by 12:00 noon today (Friday 6th November).
The motion will then go to the appropriate Committee. If they agree with it, they will recommend that Conference support it.
If Conference agrees with the Committee, which they usually do, then it’s Party Policy.
It can be that easy, depending on the motion.
It often isn’t.
If the Committee doesn’t support your motion, then to get it passed, you’re going to need to get the Committee’s decision overturned by Conference. And that’s no easier than it sounds.
