The legal grounds for revoking weapons licences

Firearms, ammunition, incapacitating sprays, and certain tools and devices with the potential to pose a risk to health or life, may only be possessed with a weapons licence issued by a competent authority. Firearms licences are both issued and revoked as administrative decisions. A revocation decision must meet the general requirements for this type of administrative act, and also specify the applicable legal grounds. When a negative decision is issued, resulting in a right being taken away (such as firearms licence revocation), special consideration should be given to the grounds, making it clear why the authority chose to take such a decision. Pursuant to the generally applicable administrative procedure laws, a statement of factual grounds should, in particular, specify the facts the court considered proven, including the underlying evidence, provide the reasons why the court dismissed other evidence as implausible, and inconclusive, and state the legal reasons for the decision, including references to the relevant laws.
