Is the Planning Committee Revolting?

Reading the minutes of the last planning committee meeting I notice that the Planning Committee overturned the Head of Planning's (or the relevant planning officer's) recommendations for refusal in all three of the applications which were subject of site visits that day. All were basically 'open countryside' locations and subject to those policies.
This seems to becoming a habit and shows a certain amount of resilience, despite the Councillors being "wet, cold and hungry" and the threat that the applications may be called in by the Assemby.
It also suggests to me that the Planning Committee are losing confidence in the planning officer's ability to make correct decisions. It also confirms that many of these decisions, by officers or members, are flawed. It all points to a failing system which needs thorough 'restructuring' and investigation.
