Line of Duty Wiki

A Regulation 15 Notice, also known as a Yellow Notice or Reg 15 is a police disciplinary notice.


The notice is found in Part 3 of The Police (Conduct) Regulations 2012. The purpose of the Regulation 15 notice is to advise the officer, as soon as practicable, that a complaint has been made or a conduct matter has come to light that warrants an investigation by the professional standards department. Such complaints can be with regard to alleged General Misconduct, or the more serious Gross Misconduct.

The notice is a protection for the officer to allow them to secure any evidence that may assist in their defence and to seek appropriate advice from a Police Federation Representative or solicitor. They have 10 working days to respond to it in writing. If an officer receives a total of three Regulation 15 Notices on their record, they are most likely to be issued with a Red Notice, which terminates their employment with Central Police.

Despite being nicknamed "the Yellow Notice", the document itself is not always printed on yellow paper.

A Disastrous Affair[]

DCI Tony Gates is issued with a notice by AC-12 for failing to declare a gratuity provided to him. The gratuity in question was a free breakfast from the Sunflower Cafe. However, the main purpose of the notice was to distract him from the main investigation into him regarding his crime figures. Gates was issued with a second notice later in the episode, when the investigation into his activities was widened.


During an interview with AC-12 it is mentioned that DS Matthew Cottan already has two notices against his record, as well as a Final Written Warning given in 2009, for dereliction of duty due to his gambling addiction. It is this, and the threat of a further red notice that convinces him to go behind the back of DCI Anthony Gates.
