“an application for…permission to enter or permission to stay may be refused where false documents are provided to the Secretary of State or a third party in support of the application whether or not to the applicant’s knowledge.”
“It is highly likely therefore that where an applicant uses in all innocence a false document for the purpose of obtaining entry clearance, or leave to enter or to remain, it is because some other party, it might be a parent, or sponsor, or agent, has dishonestly promoted the use of that document. The response of a requirement of mandatory refusal is entirely understandable in such a situation. The mere fact that a dishonest document has been used for such an important application is understandably a sufficient reason for a mandatory refusal. That is why the rule expressly emphasises that it applies whether or not to the applicant’s knowledge.”
