So given the above, Whack’s central underpinning premise is valid. So why, as he asks in the OP, does it not apply in these situations? There are two answers in the securities laws contenxt, although one is really a subset of the other. As always, the first stop is the text.
Section 10(b) of the Securities Exchange Act of 1934 (as amended) reads in relevant part:
It shall be unlawful for any person, directly or indirectly, by the use of any means or instrumentality of interstate commerce or of the mails, or of any facility of any national securities exchange–
…
b. To use or employ, in connection with the purchase or sale of any security registered on a national securities exchange or any security not so registered, or any securities-based swap agreement (as defined in section 206B of the Gramm-Leach-Bliley Act), any manipulative or deceptive device or contrivance in contravention of such rules and regulations as the Commission may prescribe as necessary or appropriate in the public interest or for the protection of investors.
Looking at that section, we see that this could be a specific intent crime. The prohibition is against “manipulative or decpetive practices” suggests that you’re not doing anything in violation if you’re not manipulating or decieving someone. Unlike say the crime of larceny, which doesn’t require you to decieve someone out of their money, just to take it.
I’m not a full-time securities lawyer, so I don’t know all the history of this stuff, but I do know tha tthe courts have read a “scienter” requirement into Section 10(b). Scienter means knowledge – that is, as I said above, to violate the statute you need some level of knowledge that what you’re doing is manipulative. There is a ton of litigation on just how broad this requirement is (and whether negligent ignorance is enough knowledge, of if you need to actually know), but the basic rule is clear – if you do something that you have no reason to suspect is manipulative, decpetive, or illegal, then in most circumstances you’re not violating 10(b).
However, it isn’t that simple. Because publicly traded companies have a responsibility to follow the laws. So they can’t just plead ignorance completely. They typically have to get advice from securities lawyers and accountants about what the proper treatment is. This means two things. First, it means that in general, ignorance remains not an excuse because you have a responsibility to learn what’s allowed. But it also means that in the securities realm, there is an “advice of counsel” defense. The securities laws are exceedingly complex and, given how often companies try to end run around them, they become more complex every day. It’s impossible for someone to know all this stuff who doesn’t do it for a living. (And even then.) So what you’re expected to do is hire a good lawyer and tell him waht you want to do. And if he tells you it’s illegal, don’t do it. But, if he tells you it’s legal and he’s wrong, well, you tried your best to be in compliance, and you failed through no fault of your own. In this situation, again, given how difficult it is for the layman to keep up with all the intricacies of securities laws, “My lawyer told me it was OK” is a valid defense. As a society we understand that it’s inappropriate to hold you to the same “ignorance is no defense” standard with these incredibly complex rules than we do with the law against shooting people. You can’t just do whatever you want, but if you make serious efforts to find out what’s legal and you proceed on the basis of what you find out, we’re not going to punish you for following bad advice.
I think that answers the question in this situation – while ignorance of the law is no excuse generally, the complexity of the securities laws and regulations mean that ignorance is a legitimate defense so long (roughly) as it’s a reasonable ignorance, especially if based on efforts to find the answers which should have yielded the correct answers but didn’t.
