Seems he may also escape prosecution.
A barrister writes:
Ryanair sparked outrage after apparently failing to remove the man, with Labour MP for East Hull Karl Turner saying the airline “failed spectacularly”.
Mr Turner, who is a qualified barrister and was once Labour’s shadow attorney general, tweeted: “Suspect the pressure to turn this aircraft around quickly and get it airborne meant that they have allowed this alleged offender to remain on the aircraft. He may now get away with it.”
He added: “@Ryanair failure to deplane the alleged racist offender, handing him over to the Spanish authorities probably means that he isn’t now prosecuted.”
He added: “Unfortunately because @Ryanair is registered in Dublin not in the UK the alleged offence could only be tried by UK authorities if it was ‘in flight’ to the UK. Section 92(1) Civil Aviation Act s.92(4) defines ‘in flight’.
“If this incident had have happened on an alternative airline under ‘British Control’ or it was already ‘in flight’ to the UK the prosecuting authorities could have prosecuted.”
