Having now downloaded and briefly read the actual report, the main issue appears to be with the operation of the ATC unit and ingrained practices, more than that of the individual. However, it does raise a question as to whether the competence of this controller had come into question previously and if so, why had nothing been done about it before this check?
I challenge the comment above about anyone with half a brain. It requires a certain kind of brain to do the job well, from experience more a practical one that is able to make quick and reasoned decisions, rather than an academic one, but certainly much more than half of one.
