Where, in the course of interviewing an applicant for a firearm licence, information comes to the attention of the police officer conducting the interview which could indicate that the applicant is unfit to possess a firearm, and which should reasonably lead to further enquiries being made, it is negligent not to make such enquiries. The police have a duty to take reasonable steps to verify information provided by firearm licence applicants and to investigate circumstances that may indicate temperamental unsuitability, including the circumstances surrounding withdrawn criminal charges disclosed during the application process. The essential question in processing firearm licence applications is not merely whether an applicant has been convicted of a crime, but whether the applicant is a suitable person to possess a firearm in all respects, including temperamental suitability. The burden is on the applicant to satisfy the police that he or she is a fit and proper person to possess a firearm, and applicants must comply with reasonable requests to provide relevant information.
