The FBI and Apple remain at loggerheads over the company's refusal to unlock the iPhone 5C of San Bernardino killer Syed Farook.
Apple has already issued two statements denying it will bend to the will of the FBI. In the second of these, the company's chief attorney argued that unlocking the phone would actually create more crime.
The tech giant's general counsel Bruce Sewell plans to argue such a move would ultimately jeapordise the cyber security of Americans, leaving them vulnerable to hackers and criminals.
District Attorney for Manhattan Cyus Vance, in his opening statement, said unlocking orders should be subject to warrants, but that Apple should not be usurping the place of the US Government in keeping the American people safe.
Barclays Plc is to publish its first earnings report since the appointment of new CEO Jes Staley in December to turn around the bank's fortunes.

Irish hoteliers are planning to invest in refurbishments this year, but remain cautious about a two-tier recovery.
2015 was the best year for Irish hotels in over a decade, and an Irish Hoteliers Federation survey shows 93% are to increase investment, while 82% have seen a rise in business so far this year.

Argentina has agreed to end its 14-year battle over debt repayments for $4.64bn.
The country has hammered out a deal with its main holdout creditors, which will be presented to Congress next week, and would allow for the country's return to global credit markets.
According to Reuters, the creditors, including billionaire Paul Singer of Elliott Management, will receive a sum totalling 75% of the outstanding amount, including interest and principal.
The deal follows the election of centre-right President Mauricio Macri in November. During his campaign, Macri pledged to take a free-market approach, abandoning the protectionism of predecessor Cristina Fernandez.
