Should developers have to provide infrastructure?

I'm surprised to hear that threats of legal actions would be an issue for local authorities. I'd have thought that they'd be able to resource legal actions without too much difficulty. Didn't Dun Laoghaire take a long running case against the owners of the infamous M50/Carrickmines site?
 
Just to reply to some comments:

The counsellors were involved in rezoning the land. Once it had been rezoned residential it was pretty inevitable that it would be built on.

The development is not small- the application in question is for less than half of the site (another application being flagged for Sept/Oct for the other side of Glenageary Rd Upper). It is in fact the largest proposed development in DLR for some years.

Some of the issues highlighted at the protest meeting (eg changing Mountown roundabout to signal controlled junction) are in fact decisions made by the planners, not the developer.

Protest meeting provided ample evidence that local opinion is pulling in all directions at once (fewer cars vs no cycle paths, not enough social housing vs too much...) Also gave wonderful sight of socialist workers party speaking in favour of retention of a golf club which none of its members will ever have the opportunity to set foot on....

Local politics is actually fascintating. This one will run and run.

Does anyone have the reply to my earlier request for clarification on contributions, if any, made by developers to the cost of providing infrastructure?

Please clarify what you mean by this comment. The minutes of the council meeting above show specifically that this site was rezoned by Minister Martin Cullen following a written request from the County Manager.
