Robert, let me try to clarify your quandry.
First, the Board has a fudiciary responsibility to act in good faith using sound business judgement. So if there is a violation they should first try to resolve the problem with the homeowner. Many HOA's hire a management company to do this so as not to have neighbor pitted against neighbor (that dirty job is given to the MC)
Just like an owner not having funds for a suit, the Board can only bring suit when there are funds to cover the expenses involved. That may include the defendants if the HOA does not prevail in court. Thus, good business judgement must be exercised. Thus, it is not always a clear decision as to whether or not to try to enforce through the courts. I think most Boards would go to court to try to get an injunction to a) go onto the property and correct the violation and b)have their legal expenses and repair expenses assessed to the property.
Sounds good so far, but take the case I recently experienced where the owner was in violation for failing to maintain their yard (weeds, thistles, dead grass). They had moved out, filed for bankrupcy, andin the current financial downturn there is negative equity in the home. What should the Board do? Since the CC&Rs did not provide for going onto the property and correcting without an injunction from a judge; and due to being in bankrupcy the HOA attorney said do nothing. However, asside from the HOA, if I lived next door I would be a good neighbor. I would water their grass with my garden hose, fertilize their grass, pull their weeds, and otherwise keep their front yard looking good.
As to testifying in court the President and/or the managing agent would testify as a witness not necessarily as a representative of the HOA. I am not an attorney so I can not say for sure but have attended legal seminars and that is what the attorneys have presented. For example, in a case involing delinquent assessments an account ledger itemizing the assessments will be needed. A managing agent who prepared the ledger could be called as a witness to get it entered into the record.
"I also believe that nearly all enforcement is done through some kind of personal give and take by the violator and the owners or the Board, or the M/C or manager, and many times if that fails the issue is just ignored. That is how it seems to operate to me." good observation Robert, IMO
