I think it falls under ethical integrity. No one is asking you to "police the industry", let's not get melodramatic.
You sir, are the one that seems to have no clue as to how courts work, believe me it's not like TV. Beyond a reasonable doubt is limited to criminal cases, not civil law suits. You can ask old OJ about that. If you remember he was acquitted in criminal court, but found guilty in civil court. The rules are completely different. I am not a lawyer, so I cannot debate actual law with you. I would suggest you speak to legal council, if you need assistance in this area. As far as my knowledge, I have been an expert witness before, and am quite comfortable with how the system works. We'll just say, the award doesn't always seem fair. But then again, you could always close up shop, and open up again under another name. But then you'd have to go change all those panel stickers again.
I don't think we're talking about personal opinions. I thought we were talking about specific code violations.
I'll pose a hypothetical question:
I'm a HO with little electrical knowledge, you come out and do some non-maintenance/non-repair work. While you are doing the work, you see two NEC code violations in the panel, performed by someone else. Since no one asked for your "opinion", you say nothing to me, and slap your highly decorated and artistically eye catching sticker on my panel.
A couple weeks later, there's a problem that occurs. So I call the number on your highly decorated and artistically eye catching sticker that's on my panel. You come by again, this time you tell me that there are two code violations in my panel that caused the problem. So I ask, why didn't you tell me when you were here before. Your answer, because you didn't ask. My response, a lot of four letter words, followed by get off my property. And forevermore, I tell anyway that needs an electrician NOT to call you.
Now, which would have served your interests better? Being ethical or not?
I get the impression that most do not agree with you on this, and for that I am satisfied. You run your business the way you like! I am comfortable with knowing whom not to call.
BTW: Did you pull a permit on the non-maintenance/non-repair work you did?
