At the inquest when the coroner asks 'why didn't you pass avoiding action?' I suppose you'll just say 'CAP 774 says I needn't'.
When RAS/RIS changed to TS/DS it was to 'reset' the rules so that everyone knew exactly what level of service and what their responsibilities were (amongst other reasons). All well and good, all defined within tight boundaries then all muddled by saying 'oh by the way you have a duty of care'. Duty of care being a grey area. So as a controller i might decide that two miles head on similar level will make me upgrade to DS from TS but my colleague may decide that 3 miles 500' apart will trigger the change. Difficult to see how you can criticize one controller in one airprox if you define rules then muddle them up
