The 2010 election of the coalition government was, in hindsight, a significant moment for the planning system. Over the parliament that followed, the coalition government brought back a commitment to 'localism' in the planning system;  strengthened neighbourhood planning, and significantly reduced the volume of central government planning policy through the introduction of the NPPF.  

The election of the coalition government also resulted in a period of minimal central government intervention in planning decisions made by local planning authorities. The number of called-in planning applications and recovered appeals hit very low levels from which they have not recovered.

The Housing and Planning Act 2016 may well be an indication that this period of primacy for local decision makers is about to change. The Act introduces extremely broad powers that enable the Secretary of State to intervene in many aspects of the planning system, from the production of Local Plans to a Planning Authorities' discretion over affordable housing policy. One of the first of these powers to come into effect, was the power to intervene in Local Plan making. 

The Planning Minister decided to use these new powers, on the day that they first came into effect, to place the adoption of Birmingham City Council's Local Plan on hold. Notably, the Local Plan had already been examined and found sound by the planning inspectorate. 

Such a rapid intervention into the very last stages of a Local Plan is significant. At the very least, it indicates a willingness by the government to get far more involved in local decision making than had previously been the case. Alternatively, it could be seen as an indication that the age of localism is at an end. Are we now entering a new era of government intervention?
