The Government appointed Inspector will write up his or her report to the Secretary of State, advising whether to Confirm the Compulsory Purchase Order or to not confirm it. Amendments can also be made. On occasion, the Secretary of State will delegate approval or otherwise to the Inspector.
The report can often take a few weeks to be submitted and then take weeks or months to be considered by Government. Often delays are due to workload within Government, with limited resources to being able to assess reports.
