>Imagine this happening for a serious criminal issue, with the years long back log on some courts, this could ruin someones life.
It can be much scarier.
There was a case in Russia when a scientist was accused in a murder that happened 20 years ago based on 70% face recognition match and fake identification as an accomplice by a criminal. [0] He spent 10 months in jail during "investigation" despite being incredibly lucky to have an alibi -- archival records of the institute where he worked, proving he was in an expedition far away from Moscow at that time. He was eventually freed but I'm afraid that police investigators that used very weak face recognition match as a way to improve their work performance stats are still working in the police.
