Harbour Revision Orders (HROS) are devolved to the Marine Management Organisation (MMO), which handles all aspects of the process, except for their final laying in Parliament. All HROS must include a formal consultation process which is overseen by the MMO, and the department is a statutory consultee on all HROS, along with other relevant bodies. These procedures for handling HROs, alongside legal checks and normal policy checks prevent HROS being used a fast-track process, as it is noted by the MMO that HROS commonly take at least a year to process.
