ADS-B Mandate – ATCs Responsible for Deaths?

[peuce]

I often wonder if Airservices/CASA have considered all the effects of greater surveillance.

For example, with a greater visibility of air traffic, have they considered the greater workload of Controllers...burdened with a duty of care to intervene in any potential conflictions...whether inside or outside Controlled Airspace?

Will more Controllers be required? If so, where from?
