Jurors at the inquest of Jean Charles de Menezes are retiring to consider their verdict.
Coroner Sir Michael Wright has ruled out unlawful killing, leaving the jury with a straight choice between lawful killing or an open verdict.
The coroner told the 11 jurors to cast aside "any emotion" over the innocent Brazilian's shooting after hearing more than seven weeks of evidence.
Tulse Hill’s Mr de Menezes, 27, was gunned down by specialist firearms officers at point blank range after being mistaken for failed suicide bomber Hussain Osman.
The coroner took the unconventional step of issuing a "questionnaire" relating to the circumstances surrounding the incident on a Tube train at Stockwell on July 22, 2005.
After choosing between lawful killing or an open verdict, the jurors must decide whether firearms officer C12 shout the words "armed police" at Mr de Menezes before firing, did Mr de Menezes stand up from his seat before he was grabbed in a bear-hug by officer Ivor and did Mr de Menezes move towards C12 before he was grabbed in a bear-hug by officer Ivor?
The jurors will then decide whether a string of additional factors - including identification, photographs, communications and orders issued from the control room at New Scotland Yard - caused or contributed to the death of Mr de Menezes.
They will have to decide whether differences in police officers' accounts were caused by "failure of recollection" or by "misunderstandings and failures of communication" at the time, the coroner said.
For the first time, the public was given a full account of the incident from key witnesses on board the Underground carriage where the shooting took place.
The inquest at the Oval cricket ground heard from 100 witnesses, including the two men who shot dead the electrician.
