Such a notice is called a “stop notice”. 85 The Scottish Ministers can issue a stop notice regardless of whether the person has a marine licence or not and (if they have a licence) regardless of whether they are operating in accordance with the licence conditions. 86 A stop notice must state the Scottish Ministers’ reasons for issuing the notice, the date and time that the activity must cease being carried out and any steps required by the Scottish Ministers to ensure safe cessation. 87 An initial stop notice can be in effect for up to seven days. The stop notice may be extended but only up to a combined total period of 35 days. 88 This limit does not apply where an activity is being carried out without a marine licence. In such cases, stop notices can remain in effect until a marine licence is granted for the activity in question.
