Commentary on Sections Part 3: Planning Control. Section 56: Directions etc. as to method of dealing with applications
The Department may make a development order to specify how applications are to be dealt with.  It can direct that a council is restricted in its power to grant permission for some developments, and require it to consider conditions suggested by the Department before granting permission on an application.  A development order may require councils and the Department to consult specified authorities or persons before determining applications.  A development order can also specify the person to whom applications need to be sent to under the Act, and who should in turn be sent copies.
