Really.. I use to follow this general definition:
An ombudsman (English plural: ombudsmans or ombudsmen) is an official, usually (but not always) appointed by the government or by parliament, who is charged with representing the interests of the public by investigating and addressing complaints reported by individual citizens. In some jurisdictions, the Ombudsman is referred to, at least officially, as the 'Parliamentary Commissioner' (e.g., the West Australian state Ombudsman). The word ombudsman and its specific meaning, Norse in origin, has since been adopted into English as well as other languages, and ombudsmen have been instituted by other governments and organizations such as the European Union.
So, you see why I dislike elections for the function - underlined. In my opinion, the best person to select the next ombudsman is the previous one. That not being the issue to be discussed here (thanks Draleg), I'll not delve into that.
As for the tasks - bolded and italicised - of the ombudsman.. I think it's quite clear.
All an ombudsman has to do is find out what reasons there are for a person to be banned/warned, posts to be deleted, etcetera, IF (and only if) the administration/moderators fail to clarify why they took said action.
Basically, those 2 things; posts edited/deleted and user warned/banned, are the only actual complaints users can have about the staff. Accusations of bias and other subjective (user-perceived) incidents are harder, but can be resolved through minor investigative work - basically asking the offended/suspicious party what they notice, and the accused party what they meant or how they came to their conclusions. Basically, one might say asking questions is the sole job of the ombudsman.

Anything beyond that is crossing lines that shouldn't be crossed.
Ombudsmen are always subject to the Administration.. might I remind everyone to the fact that the task of the Ombudsmen is to negotiate between Moderators and Community.. Administration being a completely different level is in fact impossible (and should not be wanted) to 'control' (control not being the exact word.. but I fail to find the proper word; perhaps it is 'be accountable to someone'?).

All that said, I think the whole issue of "That person represents that group!" is idiotic and childish. If you are susceptible to such accusations, you fail to be even close to the position of trust an ombudsman requires.
Of course, ombudsmen can grow into such trust positions.. by fairly representing every complaint they find they can address. If the community has a general complaint about many mods at once, the ombudsman has the responsibility to publically address the issue, but only after conducting conversations with community leaders, moderators and of course the Administration.
It's simply not possible for an ombudsman to NOT represent a user in a good and fairly presented case, as such is their job. The issues need ALL be posted in public.. so that that public can judge the ombudsman and see that he does deserve their trust.
Of course, the Administration is in the position to overrule an ombudsman at any given time. To deal with a case involving the Administration, an ombudsman would require Site Admin endorsement. I seem to recall that didn't happen, but if it were to, it would be the only option to give an ombudsman the authority to converse with the Administration at an equal level.
And with that we've reached the pinnacle of ombudsmanship.. equality. An ombudsman is level with the Community, but also with the Moderators. We all know Moderators are members of the Community with a certain extra responsibility and the power to properly account for that responsibility. Administrators on the other hand are NOT just members of this Community.. hence my little expedition into requiring the Site Admin to agree.


I guess those are my thoughts, Draleg.
