“2.11 The DBS does not have an investigatory function but, as part of its decisionmaking process, it can seek relevant information from other organisations, agencies and bodies. This can include, for example, police reports, court documents, competent body findings, adult social care or children’s services reports, and employer disciplinary hearing records. It may, therefore, approach a probation provider for disclosure of relevant information on an offender, for example from sources such as pre-sentence reports and OASys. Any requests should be considered on a case-by-case basis and in compliance with information sharing policies and data protection principles. In doing this, it is important to bear in mind that the DBS is carrying out a statutory function with the purpose of preventing crime (harm to children and vulnerable adults). It may be necessary to extract from or redact records to ensure that only information that is relevant and proportionate to the function of the DBS and to safeguarding and prevention of crime purposes is disclosed. 2.12 When considering the appropriate level of disclosure, the probation provider also needs to bear in mind that the DBS is obliged to share with the person concerned all the information it has used to make its barring decision. If information cannot be passed to the person being considered for barring, for example in the interests of the prevention and detection of crime, the DBS cannot legally consider this information in the barring decision-making process. It is required to secure only as much relevant information as is necessary and reasonably sufficient to make a fair and defensible barring decision. The test applied by the DBS in relation to barring considerations is the civil standard of proof, “on the balance of probabilities”.”
