How Faulty Software Landed Dozens of UK Postmasters In Prison (usnews.com) 64

The Associated Press reports: In a ruling that reversed one of the biggest miscarriages of justice in British legal history, 39 people who ran local post offices had their convictions for theft, fraud and false accounting overturned Friday because of what an appeals court said was clear evidence of "bugs, errors or defects" in an IT system.

The decision follows a years-long, complex legal battle that could see Britain's Post Office face a huge compensation bill for its failures following the installation, from 1999, of what turned out to be the defective Horizon computerized accounting system in local branches. Dozens of staff were convicted after the Fujitsu-supplied system pointed to an array of financial misdemeanors that bewildered the postal workers. Six others had their convictions quashed previously, while another 700 or so workers also are believed to have been prosecuted between 2000 and 2014... Jobs, homes and marriages were lost as a result of wrongful convictions, and some did not live long enough to see their names cleared by Britain's Court of Appeals.

Confirmation that the convictions were quashed was met with cheers and tears. A few bottles of bubbly were also popped.

Martin S. (Slashdot reader #98,249) writes, "As a software geek, the part I find most troubling is that blind faith that those in authority placed in the software without proper accounting..." The BBC reports some desperate sub-postmasters even "attempted to plug the gap with their own money, even remortgaging their homes, in an (often fruitless) attempt to correct an error."

The judge in the case complains that for years the Post Office had "consistently asserted that Horizon was robust and reliable" and "effectively steamrolled over any subpostmaster who sought to challenge its accuracy," according to an article in The Scotsman: Nick Read, Post Office chief executive said: "I am in no doubt about the human cost of the Post Office's past failures and the deep pain that has been caused to people affected. Many of those postmasters involved have been fighting for justice for a considerable length of time and sadly there are some who are not here to see the outcome today and whose families have taken forward appeals in their memory. I am very moved by their courage."

There were 73 convictions in Scotland caused by the failure. Although a total of 47 postmasters in England and Wales have had their cases referred to the Appeal Court, there has never been similar action in Scotland.

However, now the Scottish Criminal Cases Review Commission has written to the people it believes may also have been the victims of possible miscarriages of justice in Scotland relating to the Horizon computer system.

    Should be the ones paying now. Let them serve the same sentences that others served while they incorrectly defended the tool at the cost of their own employees livelihoods and freedom!

    • Should be the ones paying now. Let them serve the same sentences that others served while they incorrectly defended the tool at the cost of their own employees livelihoods and freedom!

      Deliberately abusing the justice system to falsely imprison someone is a much more serious crime than basic accounting fraud. Their sentences must be far greater than anything served by any of the postmasters.

  • Because the computer said so.

  • figured that out. I was wondering how in the heck all these USPS Postmasters and Postmistresses were in jail and I never heard about it before ;) Guess Postmistresses was a hint ;)

    When I was browsing earlier I saw postmistresses and chuckled wondering if the wives were jailed to;)

    So what I don't understand is how these convictions stood.

    Suppose I work for corporation XYZ, and an accounting tool says there's a million dollars missing from an account I control.

    But the authorities can't find where the million dollars went, there's no record of what account it went to. (since with this faulty software there likely was no actual theft). They can't show that I authorized the transactions. They can't show that I withdrew any cash. They can't show any accounts I own with suspiciously high balances. My house and car are the same as before.

    And they have 700 other cases that are similar, it's not just me.

    Ergo: I say I didn't do it and they cannot find any way I benefited if I did do it.

    How did this exceed the British government's standard of proof for a criminal conviction?

    • missing from the till? If they are tacking cash then it may be that I was taking the bank drops home.

      • Well again, it seems odds that 700 people don't have a shred of actual cash in their house or suspicious purchases.

        • I doubt they searched their houses, and it is not hard to hide cash. I believe the amounts "missing" were relatively small and could easily have been spent in non-spectacular or non-recordable ways - like restaurant meals or gifts for relatives. Not that it happened anyway.

      It's really surprising. The judge, summing up in one of the cases pretty much pointed this out. He said:

      There is no direct evidence of her taking any money... She adamantly denies stealing. There is no CCTV evidence. There are no fingerprints or marked bank notes or anything of that kind. There is no evidence of her accumulating cash anywhere else or spending large sums of money or paying off debts, no evidence about her bank accounts at all. Nothing incriminating was found when her home was searched...Do y

        As a software engineer myself this is also a huge red flag. It's typical for software hiding a pile of catastrophic bugs to "work" 90-99 percent of the time just fine without any problems. And for the testing team to seemingly never find anything that one time they tried a feature.

        Yet when I examine the code I find muddled logic, use of dangerous thin

        • The errors were all in the same direction. Many of the things you said would lead to random looking errors in each direction. Oh well, Iâ(TM)d love to see what the actual bugs were...
          • by jeremyp ( 130771 )

            Errors in the other direction would look like the Post Office had more money than it should have. There's no incentive to pursue that further because it doesn't look like a theft, from their point of view.

      • Regardless if the software is flawless, how would the software point out the person taking money out of the till without evidence?

        Were they assuming it was clairvoyant?

        • money_in_till = starting_money + cash_in; //BUG: does not account for giving change.
          printf("This much money should be in the till: %f", money_in_till);

          Manager counts till, finds that it doesn't contain money_in_till. It can't, because the software is reporting too much money.

          If you completely trust the software, the logical assumption is the clerk stole money from the till. After all, they were the only people with access to the till, and clerks do steal from tills sometimes, whether or not the software i

          • Or someone else has copied keys and sneaks in on lunch breaks and takes the money, or whatever ... I could see this being sufficient evidence for a civil suit after dismissal, the Brits convicting in a criminal trial purely based on this evidence suggests something is fundamentally wrong with their court system though.

        • There was no need to do this. The contract between the subpostmasters (franchisee) and the post office, specified that the subpostmaster was liable for any shortfalls in the accounts.

          If the till was short, the subpostmaster was contractually obliged to top it up.
          • by sjames ( 1099 )

            You still need a proper accountant to show that there really is a shortfall. The crux of the problem is that Horizon apparently often claims the account should have more money than it actually should.

      • I don't know how much more firmly a judge can say that it's a very weak case, yet the Jury, for some reason, accepted that software is flawless.

        I'm not a fan of trial by jury, particularly particularly when the issues are technical such as about software. A panel of independent experts should be used in such cases, otherwise the jury hasn't a clue what it is about just goes the way of the most charming lawyer.

    • by sjames ( 1099 )

      More to the point, the software claims the till should contain $200, but only $150 is actually counted. BUT, the system cannot show how the till would have gone from the $50 it started with in the morning to $200. They SHOULD have had a full accounting that could go sale by sale and show where the extra $150 should have come from. If that can only show that $100 came in, there was no theft.

      Instead, the prosecution used the old "The COMPUTER says..." (and yes, you can actually hear the all caps when someone

      I agree totally. If people had only double checked their figures they wouldn't have landed in all this legal trouble in the first place. Same goes for trusting tax preparation software. Don't sign your return until you've checked everything carefully, then double checked it!

      • Another one without a clue what they are talking about. Customers paid 100 pound. Till contains 1000 pound. Software says there should be 1500 pound. Post office insists post master stole 500 pounds, destroys evidence that the software is faulty, post master goes to jail. Nothing to sign off.

    There are only a couple of companies that I won't flat out work for - Fujitsu is the most egregious of them. Remember the great Fujitsu hard drive debacles of the 2002 era? This was one reason and Horizons is another.

    Fujitsu have lied on the stand, have colluded with the Post Office to insert false accounts into the system (they had update access to other peoples accounts and were falsley inserting records at the Post Offices behest) They have perjured on the stand, they have conspired (and succeeded!) in perverting the course of justice, and so far they have gotten away with it.

    It is high time that people simply stopped working for them. Any recruiter that calls me wanting to offer a contract is told in no uncertain terms where to go. Refuse to deal with them. Don't consider them for tender. It's not worth your companies good name to contract with these people. They are cheap for a reason - and you can see this now.

    Simply cut them off and punish them properly for their decades of failing in this regard. It's your moral duty to do so.

      Doesn't matter the company.

      Never, ever get involved in any government IT project. They are universally shit - overpriced, unutterably poorly specified, implemented by morons, and then funded into perpetuity in the hope it will magically fix itself.

      Local government, NHS, and then government QUANGOs and things like the Post Office, DVLA, etc. Never, ever, ever, ever - as an IT professional with an ounce of professional decency - go anywhere near them.

      The hard disk debacle you're talking about involved Hitachi Global Storage Systems (HGST) drives branded as IBM DeskStar made in a single plant in Europe. If you got one from a different plant, it would work fine. I have one that's still working now, and it ran almost continuously for a decade.
      • No thats a different one, and IBM fessed up and replaced the duff ones we had with no questions.

        Fujitsu HDD had a failure rate of about 80% outside the warranty period and Fujitsu just went "lalalal fingers in ears we are not listening" and cost us many thousands - we had a couple of hundred fail inside of six months. They knew there was a problem, they just decided to stonewall and completely ignore people.

    It wasn't faulty software. Rather than admit faults with the software, the Post Office put their own postmasters in jail.

  • How is this even possible? How is it that so many people got convicted without the software being tested and how did they prove where the money went? And how is it that with so many postmasters being picked up they never even suspected it could be the system? Yeah, if it where one or two I can imagine, but reading the article it goes into the hundreds.
