The review will not affect the key features of the present system but will instead concentrate on the procedural aspects of the system with a view to improving its effectiveness and efficiency.
Mr Lang said: 'Under the banner of the Citizen's Charter, my general aim is to stimulate discussion on ways in which the effectiveness, efficiency and responsiveness of the system can be improved.
'My specific aim is to assess the adequacy of the decision making process in terms of its openness, fairness, consistency, speed and accountability to all interests;
'the degree to which development plans and development control promote development and conservation objectives and in so doing add to the quality of the natural and built environment; and
'the adequacy of the arrangements for monitoring the decision making process and for measuring the achievement of objectives, targets and standards of service'.
Mr Lang added: 'I should make it clear that no significant changes will be introduced until after the reorganised authorities are firmly in place'.
