"Earlier, Mr Thwaites cross-examined immigration official Paul Roach over a counterfeit stamp found in the Brazilian's passport, asking if this meant he had been in the country illegally.
Mr Roach told the court Mr de Menezes first entered the country on 13 March 2002 and was given six months' leave to remain, before extending his stay, as a student, to 30 June 2003.
The next record was of him arriving in Ireland from France on 23 April 2005 but there was no notification of when he returned to the UK.
The court heard how as a person entering Britain from Ireland, he would have had an automatic three-month leave to remain which at the earliest would have run out on 23 July, the day after he was killed.
A counterfeit stamp found on his passport may only have been added after he entered the UK, Mr Roach said."
