Sorry? There have been departments of Weights and Measures for literaly millenia.
They have required certification of those sorts of items with regular inspections and anti-tampering seals.
So yes, you can challenge evidence from mechanical scales, if they haven't been properly inspected and certified at the required intervals under the regulations.
- mattlondon 2y agoExactly that is my point - so for the example of some mechanical scales, if they have all been properly inspected and certified, then you can expect them to be reliable and accurate. So in a case, if there is evidence against someone that relies on the scales doing their job properly, and those scales have been inspected and certified, then you probably do not have a valid argument to say "ah yeah but the scales the defendant used might have not been working properly when they used them!". I.e. the accepted assumption is that the scales work correctly. Up until recently the same sort of assumption was given to computer systems from what I can tell. This is how we got into the Post Office scandal situation where people implicitly trusted that the computer was doing the right thing.
- rswail 2y agoThe problem was that the same sort of assumption was made without any basis in reality. If there's no "inspected and certified" then there is no officially recognized evidence that the system is accurate.
