As someone who has done professional disciplinary hearings (for lawyers, security guards and PI's), as a panel member or adjudicator, let me give you some insight into what we can tell from that notice and what we can't.
The most important thing we can't tell is whether there have been previous disciplinary findings or complaints about that person. That is a big deal. First time offenders are viewed with more of an goal of correction or improvement than punishment or deterrence. If that was his first time before the panel that counts in his favour.
The fact that he pled guilty to some of the charges is also very important. It shows that he was willing to admit that he has done wrong and knows he needs to do better in the future. It is a sign of remorse and accepting responsibility. It shows an appropriate mindset.
I think the punishment is fair if he is a first time offender. He got a long probation and "suspenders" (as we like to say) which is moderately heavy. You need to keep in find that purpose of the tribunal is to protect the public from unprofessional operators, not to deliver justice of any such for you.
I would be willing to bet that even if you appeal that sentence will be upheld.
If you do appeal, please check back and let us know how it turns out.
