During a three-week trial, the prosecution have claimed that the trio used false documents in an attempt to make the bank believe they were entitled to the money.
The jurors heard that one of the men, 75-year-old lawyer Antonio Siracusa, became involved in the alleged scam after suffering financial difficulties and was found in possession of numerous fake documents.
The prosecution claim that co-accused Tommaso Caruso (50) played a key role in the operation and was involved in creating some of the documents at the heart of the alleged scam.
The third defendant, 38-year-old Enrico Vergo, became involved at a later stage, acting as an interpreter for the men when they visited the bank, on the Esplanade, in February.
The defendants deny a charge of conspiracy to commit fraud. Mr Siracusa claims he believed he was involved in a legitimate humanitarian project.
Mr Caruso claims he only became involved because he wanted to prove to Mr Siracusa, who he saw as a father figure, that he was being caught up in a scam.
Mr Verga, meanwhile, claims he thought the operation was legitimate.
Jurors were sent out at about 12.10 pm on Monday and resumed their deliberations this morning.
