Do UK immigration officials have the discretion to refuse entry to arriving visitors solely because of condescending answers, rude behavior and arrogant answers to questions?
I know the officers are free to refuse you entry by deliberately making unreasonable inferences, e.g. £3,000 for a one week visit is not enough and does not convince me you’re a genuine visitor, etc. I get that.
However my question is specifically: Do the rules allow them to refuse entry because Mr. XYZ was rude to an officer of UK immigration and thus...?
Does such a case fall under General grounds for refusal Section 3 of 5 – Considering entry at UK port
Paragraph 320(19) V 3.3
Refusing the applicant entry to the UK is conducive to the public good. For example, because of the applicant’s character, conduct or associations, it is undesirable to give them leave to enter.
For clarity I am referring to non-violent, nonaggressive, noncriminal behavior.
