As I confirmed to the House during the passage of the Planning Act, on 24 November 2009, Official Report, column 532, we are committed to a review of the evidence on the extent of development on back gardens to establish whether or not there is a clear and genuine problem. If there is a problem, we will consider action to remedy the situation, only if it would not undermine our objectives on housing.
The terms of the review are due to be decided shortly, and we will publish the information.
