Which one is it then?
lies of commission, which entails making a flat-out untrue statement, I missed where he had the flat out falsehood.
Omissions are not necessarily untrue, but they are misleading. If he had a TUE wouldn't that mean you can nullify the lies of omission?
Character lies are not necessarily untrue either, but they do attempt to create a false or misleading impression. Was he taking Vyvanse for ADHD or a competative advantage? I have a hard time believing its the latter.
without the whole story, it's hard to say if he will be sanctioned.
