>Description of Ad Hominem
>Translated from Latin to English, "Ad Hominem" means "against the man" or "against the person."
>An Ad Hominem is a general category of fallacies in which a claim or argument is rejected on the basis of some irrelevant fact about the author of or the person presenting the claim or argument. Typically, this fallacy involves two steps. First, an attack against the character of person making the claim, her circumstances, or her actions is made (or the character, circumstances, or actions of the person reporting the claim). Second, this attack is taken to be evidence against the claim or argument the person in question is making (or presenting). This type of "argument" has the following form:
>Person A makes claim X.
Person B makes an attack on person A.
Therefore A's claim is false.
The reason why an Ad Hominem (of any kind) is a fallacy is that the character, circumstances, or actions of a person do not (in most cases) have a bearing on the truth or falsity of the claim being made (or the quality of the argument being made).
>Example of Ad Hominem
>Bill: "I believe that abortion is morally wrong."
Dave: "Of course you would say that, you're a priest."
Bill: "What about the arguments I gave to support my position?"
Dave: "Those don't count. Like I said, you're a priest, so you have to say that abortion is wrong. Further, you are just a lackey to the Pope, so I can't believe what you say."

Or, here is another example:
I don't even need to read the article because they aren't a doctor and so they don't know what they are talking about and they are probably an anti-psychiatrist* anyway!
(Even though anti-psychiatrists are psychiatrists who have criticisms of the current state of psychiatry. Szasz, Breggins etc were trained as psychiatrists, worked on in-patient wards, worked as therapists, prescribed medication etc etc etc. The appropriate ad hominum attack is really 'scientology'. You know, waiting for the UFO's to come back. Clearly anyone who suggests that ECT might not be appropriate as a first line treatment for depression must believe that the UFO's are coming back...)

It should be noted that much of the literature in the journals exhibits a considerable bias - typically in the other direction as when researchers / clinicians have a financial investment or tie to a particular pharma company or ECT manufacturer (which they often don't disclose). This person was upfront about their bias. What the person has to say should be assessed on its merits. As should those who have financial ties to pharma. While a paralegal isn't qualified to be RUNNING experiments I would think that the critical thinking skills could be useful for offering a review on the findings of the experiements that had been run.
I don't know what happened in the court of law but my feeling was that the information that the paralegal found would be presented in order to question the claim that a competent psychiatrist wouldn't know about the considerable risks to memory etc in order to adequately inform their patient and / or the patients family of the risks. I don't imagine the judge would have said 'you are a lawyer, what do you know? The doc said he didn't know and since he is a doc he must be competent (the opposite of an ad hominum - an appeal to authority).
The primary sources are referenced so if one is dubious one could in fact chase up the primary sources oneself.
