It would set a precedent for important local issues for years to come.
Would any councillor who campaigned on a social issue, for example, be barred from voting on measures to deal with it?
That's why it's murky territory.
Should the councillors vote, the council faces a legal risk. It has an obligation, on our behalf as ratepayers and residents, to avoid messy and potentially costly legal complications.
Should they not vote, the decision could be seen to be fatally flawed. We elected a mayor and 12 councillors - a cross-section of our district - to represent us. Don't they all have their own opinions that should be taken into account?
We've noted before that next Tuesday's decision will likely not be the end of the matter.
This council has achieved a lot in a short time since the 2013 election. We've seen and heard the plans - there's still a lot to be done. Let's hope this issue can be put to rest soon and our elected representatives can get on with everything else they need to do.
