Almost 40 new instances have been postponed underneath a two-month moratorium on using cell phone information in trials, which was imposed after police discovered a number of glitches within the software program that converts uncooked information from cellphone masts into usable proof.
Among the many errors police have found is a bent for the system to omit some information throughout the conversion course of, that means solely chosen calls are registered and the image of the cellphone’s location is materially incomplete.
The system has additionally linked telephones to the incorrect masts, related them to a number of towers without delay, typically lots of of kilometres aside, recorded the origins of textual content messages incorrectly and obtained the placement of particular towers incorrect.
Taken collectively, the issues meant not simply that harmless individuals might doubtlessly have been positioned at crime scenes however that criminals might have been wrongly excluded from inquiries, mentioned Jan Reckendorff, Denmark’s director of public prosecutions.
“It is a very, very severe situation,” he informed Denmark’s state broadcaster DR. “We merely can not reside with the concept info that isn’t correct might ship individuals to jail.”

The Danish justice minister, Nick Haekkerup, welcomed the choice, saying the primary precedence should at all times be to keep away from miscarriages of justice. “We shouldn’t take the chance that harmless individuals might be convicted,” he mentioned.
Operators insist the errors have largely stemmed from the interpretation of their information and so they shouldn’t be held accountable. Authorities contend that in some situations the information has additionally been at fault, however Jakob Willer, of the nation’s telecoms business affiliation, mentioned it was not their job to offer proof.
“We must always keep in mind: information is created to assist ship telecom companies, to not management residents or for surveillance,” Willer mentioned. He conceded it might be priceless to police, however insisted its major function was to facilitate communication between customers.
There are not any statistics on what number of courtroom instances in Denmark are selected the idea of cell phone information, however it’s typically used to corroborate different proof and, though not thought of as dependable as DNA, has beforehand been seen as extremely correct.
Karoline Normann, the pinnacle of the Danish legislation society’s legal legislation committee, mentioned proof as soon as thought of purely technical was now open to doubt. “Till now, cellular information has had a excessive significance and worth in courtrooms as a result of this type of proof has been thought of virtually goal,” she informed Agence-France Presse.
“This case has modified our mindset about cellphone information. We’re most likely going to query it as we usually query a witness or different kinds of proof, the place we take into account circumstances like who produced the proof, and why and the way.”
Remoted incidences of clearly inaccurate cellular information have occurred prior to now within the US and South Africa, however that is the primary time it has been questioned by a nationwide justice system. Three years in the past a Kansas household sued a digital mapping firm after being visited “numerous instances” by police.
Slightly than wait for his or her case to be examined underneath the evaluate, Danish prisoners have began demanding their launch on the grounds that their convictions had been primarily based on cell phone proof.
Not all are profitable. Two members of an an Aarhus legal gang – considered one of whom insisted he had spent the night time at his dad and mom’ house however was positioned at a criminal offense scene by cell phone information – had their appeals turned down this week as a result of different proof was thought of conclusive.
