The worst in my opinion may be the examiner jackson. Committed the ultimate failure in the whole examining system, may have contributed to the death of two people and he gets costs!!
The only failure he was convicted of was "knowingly making a false entry in the skill test document", in relation to the times and airfields. The narrative does read like the CAA suspected him of something more, but he wasn't prosecuted on anything more. So it's pure speculation to make any connection between his incorrectly recorded skill test record and the deaths of the guy he passed, and his wife, a month later.
