A group of 42 sub-postmasters and postmistresses will learn later whether convictions for stealing money will be quashed amid a Post Office IT scandal.
What is the Horizon computer scandal?
The Horizon system, developed by the Japanese company Fujitsu, was first rolled out in 1999 to some post offices to be used for a variety of tasks including accounting and stocktaking.
But from an early stage it appeared to have significant bugs which could cause the system to misreport, sometimes involving substantial sums of money.
Horizon-based evidence was used by the Post Office to successfully prosecute 736 people.
But campaigners fought a long and series of legal battles for compensation in the civil courts, which have been followed by referrals by the Criminal Cases Review Commission.
