Salmon Letters

In Britain, Salmon Letters, or Crampton Letters, are official letters sent out by a public inquiry to people who will be subject to criticism when the inquiry's report is released. The aim of the letter is to give the person a chance to prepare for the resultant exposure and possible legal recourse which may need to be taken when allegations against them become public. The letters also serve to inform someone of the allegations they may have to answer during the tribunal period of the inquiry which may become matters of interest to the public once the report is published.
Salmon Letters are named after Cyril Salmon, Baron Salmon, who first conceived of the idea in 1966 when chairing a report into how tribunals of inquiry were to be conducted.
The letters are also known as Maxwellisations after Robert Maxwell, who complained after criticism of his dealings in a public report. Other reports have delved further into this process, leading to them also being named after those reports, as Crampton Letters and Scott Compliance.
Salmon Letters are often sent out in the initial stages of an inquiry, with more dispatched later if further allegations are made. This is common in child abuse inquiries, such as the North Wales Child Abuse Inquiry which started in 1996. The Department for Education's guidelines on the matter include a sample letter which points out to alleged perpetrators that the resultant report has no connection to criminal or any other proceedings.
Salmon Letters have been sent out in most major public inquiries since first being recommended by Baron Salmon in his report Royal Commission on Tribunals of Inquiry. In some cases, particularly the Chilcot Inquiry it has been cited that delay on the part of those being criticized, in responding to allegations, has led to a delay in the final report. The Scott Inquiry report noted that adherence to the rules of Salmon Letters had been 'unhelpful' in obtaining clarity.
Whilst the original 1966 report determined that the notification of an allegation was within the fairness of such an inquiry, the responsibility to send the letters out was not enshrined in the Inquiries Act of 2005. However, the Inquiries Rules Act of 2006 requires the chairperson of an inquiry to call the person's attention where the inquiry will be critical of their conduct. This would normally be in the form of a warning letter. The Act stipulates that;
...The inquiry panel must not include any explicit or significant criticism of a person in the report, or in any interim report, unless

a. the chairman has sent that person a warning letter; and

''b. the person has been given a reasonable opportunity to respond to the warning letter.''
