Questione giuridica chiave
Whether the appellate authority could rely on secret reference materials to assess the authenticity of the foreign driving licence without granting access or meaningful inspection to the applicant and the reviewing court.
Decisione estratta
The authority violated the right to be heard by relying on undisclosed reference materials without enabling appropriate inspection and adversarial comment; the finding of forgery could not stand on that basis.
Motivazione estratta
Police secrecy interests may justify protecting the reference database from full disclosure, but the deciding court must still be able to review the evidence and the party must be able to comment on the relevant comparison criteria in a meaningful way.
